TRANSCRIPT OF AUDIO

From the Cumberland Gap to the Atlantic Ocean, this is Virginia Water Radio for the week of November 29, 2021.  This episode is part of a series this year of winter-related episodes.

MUSIC – ~10 sec – instrumental.

That excerpt of “Mid-winter Etude,” by Timothy Seaman of Williamsburg, Va., opens our annual episode on winter preparedness.  This coincides with Virginia Winter Weather Awareness Week, which is being observed this year from November 29 to December 3, according to the Wakefield, Va., National Weather Service office.

In 2021, winter astronomically begins in Virginia on December 21 at 10:59 a.m.  That’s the Eastern Standard time of the winter solstice in the Northern Hemisphere, when that hemisphere is at its maximum annual tilt away from the sun. 

At its beginning, middle, or end, winter can bring cold temperatures, hazardous roads, power outages, and fire hazards.  To help you be prepared, here are 10 tips compiled from information provided by the Virginia Department of Emergency Management, the Federal Emergency Management Agency, and the U.S. Centers for Disease Control and Prevention, or CDC.

1. Avoid traveling in winter-storm conditions if you can. If you must travel, get road conditions from the Virginia 511 telephone system, Web site, or app.   And have an emergency kit for your vehicle, including jumper cables, water, non-perishable food, blankets, a flashlight, and other items.

2. Have battery-powered sources of lighting and information, particularly weather information, along with enough batteries to last through a power outage of several days.  Whenever possible, use flashlights and not candles during power outages.  If you do use candles, put them in safe holders away from anything combustible, and don’t leave a burning candle unattended.

3.  Make a family emergency plan that covers sheltering; evacuation from your area; escape from a home fire; emergency meeting places; communications; a supply of food, water, and medications; and other factors specific to your circumstances; and practice your plan.

4.  Get fireplaces, wood stoves, and chimneys inspected and cleaned.

5.  Install a smoke detector in every bedroom and on every floor level, test them monthly, and replace the batteries at least annually.

6.  Install a carbon monoxide detector in your home and check or replace the battery every six months.

7.  If you use space heaters, make sure they’ll switch off automatically if the heater falls over; plug them into wall outlets, not extension cords; keep them at least three feet from combustible objects; don’t leave heaters unattended; and check for cracked or damaged wires or plugs.

8.  Generators, camp stoves, and other devices that burn gasoline or charcoal should be used outdoors only.

9.  Learn where to shut off water valves in case a pipe bursts.

And 10.  Be careful of overexertion during snow shoveling.

More information on preparing for winter weather, fires, and other emergencies is available online from the Virginia Department of Emergency Management, at vaemergency.gov.

Next time the forecast calls for snow, freezing rain, or other wintry weather, here’s hoping that you can stay warm, dry, and safe.

Thanks to Timothy Seaman for permission to use this week’s music, and we close with about 25 more seconds of “Mid-winter Etude.”

EXTRA INFORMATION ABOUT WINTER WEATHER PREPAREDNESS AND FIRE SAFETY

On Winter Weather Preparedness

The following information is quoted from the Virginia Department of Emergency Management (VDEM), “Winter Weather,” online at https://www.vaemergency.gov/winter-weather/, accessed 11/29/21.

Winter storms can range from freezing rain or ice, to a few hours of moderate snowfall, to a blizzard that lasts for several days.  Many winter storms are accompanied by dangerously low temperatures, power outages and unpredictable road conditions.  Before, during, and after a winter storm, roads and walkways may become extremely dangerous or impassable.  Access to critical community services such as public transportation, child care, healthcare providers and schools may be limited.  Preparing your home, car and family before cold weather and a winter storm arrives is critical.

Overview for Dealing with a Winter Storm
*During a winter storm, stay off the roads as much as possible and only drive when absolutely necessary.  Always give snow plows the right of way.
*Never use a generator, grill, camp stove or gasoline, propane, natural gas or charcoal burning device inside your home, garage, basement, crawlspace or any other partially enclosed area.
*Snow shoveling is a known trigger for heart attacks!  Always avoid overexertion when shoveling.
*When severe weather occurs, plan to check on elderly or disabled neighbors and relatives.
*If you must travel, know road conditions before you leave home.  Visit 511Virginia.org or call 511 for road condition updates.
*Protect yourself from frostbite!  Hands, feet and face are the most commonly affected areas so wear a hat, mittens (which are warmer than gloves) and cover your mouth with a scarf to reduce heat loss.
*Keep dry!  Change out of wet clothing frequently to prevent a loss of body heat.
*Wear several layers of loose-fitting, lightweight, warm clothing rather than one layer or heavy clothing.

Prepare Your Home
*Make sure your home is properly insulated.
*Check the weather stripping around your windows and doors.
*Learn how to shut off water valves in case a pipe bursts.
*Have additional heat sources on hand in case of a power outages.
*Keep a fire extinguisher accessible.
*Replace the batteries in your carbon monoxide detector annually.

Prepare Your Car
*Batteries lose power as temperatures drop, be sure to have yours tested.
*Check your car’s antifreeze level.
*Have your radiator system serviced.
*Replace your car’s windshield wiper fluid with a wintertime mix.
*Proactively replace your car’s worn tires and wiper blades.
*To help with visibility, clean [snow or ice] off your car entirely, including your trunk, roof, windows and headlights.

Did You Know?
*Dehydration can make you more susceptible to hypothermia.
*If it’s too cold for you, it’s too cold for your pet!  Don’t leave pets outside for prolonged periods of time and have plenty of fresh, unfrozen water on hand.
*Each year, snow, sleet, slush and/or ice on the road leads to approximately, 537,000 crashes, 136,000 injuries, and 1,800 deaths.
*It can snow at temperatures well above freezing
*Temperatures do not have to be below zero degrees to cause harm

On Fire Safety

The following information is quoted from the Virginia Department of Emergency Management (VDEM), “Fires,” online at https://www.vaemergency.gov/fires/, accessed 11/29/21.

In just two minutes, a fire can become life-threatening.  In just five minutes, a home can be engulfed in flames.

Learn About Fires
*Fire is FAST! 
In less than 30 seconds a small flame can turn into a major fire. It only takes minutes for thick black smoke to fill a house or for it to be engulfed in flames.
*Fire is HOT! 
Heat is more threatening than flames. Room temperatures in a fire can be 100 degrees at floor level and rise to 600 degrees at eye level. Inhaling this super-hot air will scorch your lungs and melt clothes to your skin.
*Fire is DARK! 
Fire starts bright, but quickly produces black smoke and complete darkness.
*Fire is DEADLY! 
Smoke and toxic gases kill more people than flames do. Fire produces poisonous gases that make you disoriented and drowsy. Asphyxiation is the leading cause of fire deaths, exceeding burns by a three-to-one ratio.

Create and Practice a Fire Escape Plan
*In the event of a fire, remember that every second counts, so you and your family must always be prepared.  Escape plans help you get out of your home quickly.
*Twice each year, practice your home fire escape plan.  Some tips to consider when preparing this plan include:
*Find two ways to get out of each room in the event the primary way is blocked by fire or smoke.
*A secondary route might be a window onto a neighboring roof or a collapsible ladder for escape from upper story windows.
*Make sure that windows are not stuck, screens can be taken out quickly, and that security bars can be properly opened.
*Practice feeling your way out of the house in the dark or with your eyes closed.
*Teach children not to hide from firefighters.  

Smoke Alarms
*A working smoke alarm significantly increases your chances of surviving a deadly home fire.
*Install both ionization AND photoelectric smoke alarms, OR dual sensor smoke alarms, which contain both ionization and photoelectric smoke sensors.
*Test batteries monthly.
*Replace batteries in battery-powered and hard-wired smoke alarms at least once a year (except non-replaceable 10-year lithium batteries).
*Install smoke alarms on every level of your home, including the basement, both inside and outside of sleeping areas.
*Replace the entire smoke alarm unit every 8-10 years or according to manufacturer’s instructions.
*Never disable a smoke alarm while cooking – it can be a deadly mistake.

Smoke Alarm Safety for People with Access or Functional Needs
*Audible alarms for visually impaired people should pause with a small window of silence between each successive cycle so that they can listen to instructions or voices of others.
*Smoke alarms with a vibrating pad or flashing light are available for the hearing impaired. Contact your local fire department for information about obtaining a flashing or vibrating smoke alarm.
*Smoke alarms with a strobe light outside the home to catch the attention of neighbors, and emergency call systems for summoning help, are also available.

During a Fire
*Crawl low under any smoke to your exit – heavy smoke and poisonous gases collect first along the ceiling.
*Before opening a door, feel the doorknob and door. If either is hot, or if there is smoke coming around the door, leave the door closed and use your second way out.
*If you open a door, open it slowly. Be ready to shut it quickly if heavy smoke or fire is present.
*If you can’t get to someone needing assistance, leave the home and call 9-1-1 or the fire department. Tell the emergency operator where the person is located.
*If pets are trapped inside your home, tell firefighters right away.
*If you can’t get out, close the door and cover vents and cracks around doors with cloth or tape to keep smoke out.  Call 9-1-1 or your fire department. Say where you are and signal for help at the window with a light-colored cloth or a flashlight.
*If your clothes catch fire, stop, drop, and roll – stop immediately, drop to the ground, and cover your face with your hands.  Roll over and over or back and forth until the fire is out.  If you or someone else cannot stop, drop, and roll, smother the flames with a blanket or towel.  Use cool water to treat the burn immediately for 3 to 5 minutes.  Cover with a clean, dry cloth.  Get medical help right away by calling 9-1-1 or the fire department.

Fire Escape Planning for Older Adults and People with Access or Functional Needs
*Live near an exit. You’ll be safest on the ground floor if you live in an apartment building. If you live in a multi-story home, arrange to sleep on the ground floor, and near an exit.
*If you use a walker or wheelchair, check all exits to be sure you get through the doorways.
*Make any necessary accommodations, such as providing exit ramps and widening doorways, to facilitate an emergency escape.
*Speak to your family members, building manager, or neighbors about your fire safety plan and practice it with them.
*Contact your local fire department’s non-emergency line and explain your special needs. Ask emergency providers to keep your special needs information on file.
*Keep a phone near your bed and be ready to call 911 or your local emergency number if a fire occurs.

After a Fire – The following checklist serves as a quick reference and guide for you to follow after a fire strikes.
*Contact your local disaster relief service, such as The Red Cross, if you need temporary housing, food and medicines.
*If you are insured, contact your insurance company for detailed instructions on protecting the property, conducting inventory and contacting fire damage restoration companies.  If you are not insured, try contacting private organizations for aid and assistance.
*Check with the fire department to make sure your residence is safe to enter. Be watchful of any structural damage caused by the fire.  The fire department should see that utilities are either safe to use or are disconnected before they leave the site.  DO NOT attempt to reconnect utilities yourself.
*Conduct an inventory of damaged property and items.  Do not throw away any damaged goods until after an inventory is made.  Try to locate valuable documents and records.
*Begin saving receipts for any money you spend related to fire loss.  The receipts may be needed later by the insurance company and for verifying losses claimed on income tax.
*Notify your mortgage company of the fire.

Cooking
*Stay in the kitchen when you are frying, grilling, or broiling food. If you leave the kitchen for even a short period of time, turn off the stove.
*Wear short, close-fitting or tightly rolled sleeves when cooking.
*Keep children away from cooking areas by enforcing a “kid-free zone” of 3 feet around the stove.
*Position barbecue grills at least 10 feet away from siding and deck railings, and out from under eaves and overhanging branches.

Smoking
*Smoke outside and completely stub out butts in an ashtray or a can filled with sand.
*Soak cigarette butts and ashes in water before throwing them away. Never toss hot cigarette butts or ashes in the trash can.
*Never smoke in a home where oxygen is used, even if it is turned off. Oxygen can be explosive and makes fire burn hotter and faster.
*Be alert – don’t smoke in bed! If you are sleepy, have been drinking, or have taken medicine that makes you drowsy, put your cigarette out first.

Electrical and Appliance Safety
*Frayed wires can cause fires. Replace all worn, old or damaged appliance cords immediately and do not run cords under rugs or furniture.
*If an appliance has a three-prong plug, use it only in a three-slot outlet. Never force it to fit into a two-slot outlet or extension cord.
*Immediately shut off, then professionally replace, light switches that are hot to the touch and lights that flicker.

Portable Space Heaters
*Keep combustible objects at least three feet away from portable heating devices.
*Buy only heaters evaluated by a nationally recognized laboratory, such as Underwriters Laboratories (UL).
*Check to make the portable heater has a thermostat control mechanism, and will switch off automatically if the heater falls over.
*Only use crystal clear K-1 kerosene in kerosene heaters. Never overfill it. Use the heater in a well-ventilated room.

Fireplaces and Woodstoves
*Inspect and clean woodstove pipes and chimneys annually and check monthly for damage or obstructions.
*Use a fireplace screen heavy enough to stop rolling logs and big enough to cover the entire opening of the fireplace to catch flying sparks.
*Make sure the fire is completely out before leaving the house or going to bed.

Children
*Take the mystery out of fire play by teaching children that fire is a tool, not a toy.
*Store matches and lighters out of children’s reach and sight, preferably in a locked cabinet.
*Never leave children unattended near operating stoves or burning candles, even for a short time. 

More Prevention Tips
*Never use a stove range or oven to heat your home.
*Keep combustible and flammable liquids away from heat sources.
*Portable generators should NEVER be used indoors and should only be refueled outdoors or in well-ventilated areas.

TRANSCRIPT OF AUDIO

From the Cumberland Gap to the Atlantic Ocean, this is Virginia Water Radio for the week of November 22, 2021.  This revised episode from January 2014 is part of a series this year of winter-related episodes.

SOUND – ~5 sec

That’s the landing sound of a large, distinctive duck that can be found in winter on Virginia’s coastal waters.  Have a listen for about 10 seconds to some more of this species’ sounds, and see if you know this bird.  And here’s a hint: the bird’s name, and the male’s beautiful color, may remind you of a painting.

SOUND – ~12 sec

If you guessed a Canvasback, you’re right!  Canvasbacks breed on water bodies in the prairies of Canada and the northern United States, but they winter in large sections of the U.S. and Mexico, with one concentration in the Chesapeake Bay area.  According to the Chesapeake Bay Program, at one time almost half of North America’s Canvasbacks wintered around the Chesapeake, but that number has decreased to about 20 percent because of reductions in Bay submerged aquatic vegetation, or Bay grasses, a valuable winter food for this species.  Canvasbacks are diving ducks, meaning they typically go completely underwater to obtain food and avoid predators.  In winter, Canvasbacks feed largely on plant roots and buds, while in summer they’ll add to their plant diet a variety of aquatic insects and other animals. 

Predators on adult and young Canvasbacks include mink, coyotes, foxes, owls and other birds, some reptiles and fish, and human hunters, while Canvasback eggs are eaten by various mammals and birds.

The Canvasback is considered one of the most distinctive North American ducks.  The following quote from the Cornell Lab of Ornithology’s “Birds of the World” Web site describes how the bird stands out.  Quote: “This exclusively North American species is considered the ‘aristocrat of ducks.’  The male's striking appearance—rich chestnut-red head and neck, black chest, white back, and long, sloping, blackish bill—along with its large size distinguish it in the field.”  Unquote.

Thanks to Lang Elliott for permission to use the Canvasback sounds, from the Stokes Field Guide to Bird Songs.  We close with about 50 seconds of music appropriate for the Canvasback’s Chesapeake Bay connection.  Here’s “Chesapeake Bay Ballad,” by Torrin Hallett, a graduate student at the Yale School of Music.

EXTRA INFORMATION ABOUT CANVASBACK DUCKS

The scientific name of the Canvasback is Aythya valisineria.

Here are some points about Canvasbacks, excerpted from the Virginia Department of Wildlife Resources (formerly Department of Game and Inland Fisheries), “Fish and Wildlife Information Service/Canvasback,” online at https://services.dwr.virginia.gov/fwis/booklet.html?&bova=040064&Menu=_.Taxonomy&version=18949.

Physical Description

“The adult male has a head that is rusty red, shading to almost black near the bill.  The breast is grayish-black and the sides and back are light gray to white.  The wings and speculum are gray, and the eye is red.  The bill is long and sloping, black, with decidedly long sloping profile that clearly distinguishes it from the redhead. …The adult female head is light brown.  The sides and breast are olive-brown to gray-brown, and the underparts are light gray. The back is gray, finely barred with darker gray, and the wings are grayish brown.  …They have short wings, and a rapid wingbeat.  This species has difficulty leaving the water.  It is one of the fastest flying ducks.  …It is one of the largest ducks.”

Breeding

“The breeding season is from May to June… This species breeds in Alaska, western Canada, northwest United States, western North America from the prairie provinces of Canada, south into the central and western states and occasionally as far east as Hudson Bay with a few as far north as Alaska.  Spring and early summer they are found in marshes with shallow waters [and in] flooded farmland.  In mid-summer they frequent large marshes and lakes, sloughs, and swampy areas.”

Migration and Winter Habitat and Behavior

“During migration, they fly in large ‘V’ shaped flocks at high altitudes. … They are also associated with larger bodies of water.  …Late migration is in the fall, and early migration in the spring.  This species migrates cross country from the northwestern United States to the Atlantic Coast, principally the Chesapeake Bay.  The migration corridors shift annually, and they have a strong tendency to return to the same breeding ground.  … The heaviest flight is from the Canada pothole country to the Chesapeake Bay. … They arrive at Chesapeake Bay later than most other ducks.  The Chesapeake Bay fall migration is from October 15 to December 15, with a peak from November 15 to December 15.  The spring migration is from February 20 to May 1, with the peak from March 1 to March 30.  They occupy specific and traditional rivers, lakes, and marshes on migratory areas.  … This species winters to Mexico [and to the] Atlantic and Gulf Coast.  ...Virginia is one of best areas for canvasbacks.    They are found in lakes, salt bays and estuaries, brackish and alkaline waters near the coast, estuaries and shallow bays, [and] rarely on the open sea. … The optimum in Chesapeake Bay areas is in fresh and brackish estuarine bays with extensive beds of submerged plants or abundant invertebrates, primarily in brackish rather than salt or freshwater areas. … There has been a 53% decline in wintering populations in the United States.  There has also been a decrease in the Atlantic flyway.”  [Population decreases have been caused by several factors, including drainage of breeding marshland, food supplies being depleted by carp and swan, pollution of wintering areas, disappearance of submerged aquatic vegetation in the Chesapeake Bay, droughts on breeding grounds, oil spills, and illegal hunting and trapping.]

Diet

“This species dives and obtains food from the bottoms of ponds, lakes, large rivers, open marshes, and muddy bottoms.  Plants are uprooted and the roots are eaten.  This species dives to 20-30 feet. … Important foods include…aquatic plants…, molluscs, insects, caddisfly and midge larvae, dragonflies, [and] small fish.  Chesapeake Bay foods include wild celery, widgeon grass, eelgrass, pondweed, clams and mud crabs.  Juvenile foods include caddisfly larvae, midge larvae, and mayfly nymphs.”
