Winter

Winters are cold, snowy, and temperatures around -30°F (-34.4°C) are common in the northern counties - in fact, during the coldest month of January the mercury may plummet to -40°F (-40°C). Clouds cover the skies for a significant part of the year in many places.

WINTER STORM RESOURCES

Winter storms are bad weather that generates precipitation at low temperatures such as snow, sleet, and freezing rain. Winter storms can range from light snow flurries to a blizzard, which is a long-lasting storm with very strong winds and intense snowfall. Because strong winds can carry heat away from the body, it may often feel colder outside during a storm than the temperature would indicate, called the wind chill. Risks due to winter storms can include traffic accidents on icy roads, heart attacks from shoveling snow, or hypothermia from prolonged exposure to the cold.

BEFORE ...

Be informed about how to access updated weather information. Families should know what winter storm conditions are expected in their area and which official radio stations, websites, and/or social media will provide weather updates and alerts. They should also learn how schools and their employers will provide notifications of early closings or cancellations. Help families to understand the different winter storm alerts:

Winter Weather Advisory: An accumulation of snow, freezing rain, freezing drizzle, and sleet is expected but won’t reach watch or warning level criteria. The storm will likely cause inconvenience, requiring heightened awareness and the need to exercise caution.

Winter Storm Watch: The possibility of a blizzard, heavy snow, heavy freezing rain, or heavy sleet exists for the watch area. A winter storm watch is usually issued 12 to 48 hours before the event, and people in the watch area should start preparedness activities such as shopping for groceries and other supplies.

Winter Storm Warning: Hazardous winter weather in the form of heavy snow, heavy freezing rain, or heavy sleet is expected in the warning area. A winter storm warning is usually issued 12 to 24 hours before the event.

Blizzard Warning: When a storm has sustained or gusty winds of 35 mph or more, and snow or blowing snow decreases visibility to ¼ mile or less. These conditions will last for at least 3 hours and families should stay indoors.

Frost/Freeze Warning: Issued when below-freezing temperatures are expected. 

Wind Chill Advisory: Issued when the wind chill temperature is forecast to be between -15˚F to -24˚F.

Wind Chill Warning: Issued when the wind chill temperature is forecast to be -25˚F or lower. 

Have working smoke and carbon monoxide detectors. Storms can cause power outages and increase the risk of house fires and carbon monoxide poisoning when people improperly use alternate sources for heat and cooking. 

Know how to stay warm in the event of a power outage. Encourage families to have a back-up heat source, such as a wood-burning fireplace or stove. It is never safe to use a generator, grill, camp stove, or other gasoline/propane/charcoal-burning device indoors. Families that need assistance staying warm in the event of a power outage should locate a person nearby with whom they can stay or a community shelter or “warming center.” Ensure that families have warm coats, gloves or mittens, hats, warm clothing, and extra blankets to help stay warm. 

Assemble an emergency supply kit. Families should have access to enough water, food, and other emergency supplies. Families should also include a radio with batteries to get weather updates and supplies for pets. Children can also pack their own kits and include their favorite toys. Review the family preparedness plan for additional guidance.

Keep vehicles prepared for winter weather. Families should keep vehicles’ gas tanks at least half full throughout the winter to prevent the fuel line from freezing. It is best to keep a winter survival kit in their vehicle, including items such as a shovel, blankets, and windshield scraper. 

Plan for children’s needs. Families should give children factual information about winter storms in simple terms. Parents can include children in preparedness activities. The mobile app Help Kids Cope provides information on how to talk with children of different developmental levels.

DURING...

Knowing what to do during a winter storm can help families stay safe. Consider the following: 

During a winter storm watch, families should:

Monitor the local weather forecast for winter storm alerts and current updates. Make sure phones can receive Wireless Emergency Alerts (WEA) and stay aware of changing weather conditions. Temperatures may drop rapidly, winds may increase, or snow may begin to fall at heavy rates.
Monitor the school district website for school closures or other important updates.

Prepare their home for the winter storm. Families should stock their home with enough non-perishable food and water for 3 days (may need more depending on the length of the storm). Have them also stock up on supplies for potential power outages, including batteries, flashlights, and firewood. It is also helpful to keep mobile devices fully charged.

During a winter storm warning, families should:

Check the temperature and wind chill before sending children out to play. Children should stay indoors if the wind chill is 10˚F or lower.

Keep children warm and protected when playing outside. Children should have a snack before going out to give their bodies energy in the cold weather. Children also need to wear sunscreen, as snow can reflect a significant percent of the sun’s ultraviolet rays. Parents or caregivers should dress children warmly in layers of clothes. Older babies and young children need one more layer of clothing than an adult would wear. Wool and other fabrics are preferable to cotton. Waterproof pants and jackets are great top layers, and children should also wear warm socks, boots, mittens, and a hat. Scarves and face masks can help minimize skin exposure. Children should come inside when they’re cold, start to shiver, or their teeth chatter.

Avoid unnecessary trips and take precautions when traveling. Encourage families to keep their cell phones charged and with them at all times, and let someone know where they are going, how they will get there, and when they expect to arrive. If their car gets stuck, families should stay with it and wait for help unless help is visible within 100 yards. 

Take steps to stay warm in the event of a power outage. Families should always follow manufacturer’s instructions when using a generator. A generator should always be used outside and away from windows and doors. To keep warm, families should wear several layers of lightweight, warm clothing and hats, mittens, and scarves. To retain heat in the home, seal off unused rooms by stuffing towels in the cracks under the doors and cover the windows with blankets or sheets at night. If without heat for a long time or feeling unsafe, have families go to a friend’s or family’s house or a community warming center/shelter. 

Keep pets inside during cold winter weather.

AFTER...

After a winter storm, most families will recover and be able to return to their normal routines rather quickly. Most children will demonstrate resilience after a winter storm, however, some children may react differently if they were injured in a car accident or experienced the loss of a loved one or pet and may need additional grief support to help them adjust.

WINTER SEASON

The winter season brings a variety of adverse weather extremes. You may experience heavy snow, ice accumulation, freezing temperatures and wind chill. Winter storms are often called the "deceptive killers" since many deaths can be attributed to indirect causes of adverse weather. For example, icy roads lead to an increase in traffic accidents.  Prolonged exposure to the cold may enhance chances for hypothermia, and stress from snow removal my increase changes for heart  related problems. It is important to recognize the different types of extreme weather that can be experienced during the winter season.

Cold Temperatures

Exposure to cold can cause frostbite or hypothermia and become life-threatening. Infants and elderly people are most susceptible. What constitutes extreme cold varies in different parts of the country. In the South, near freezing temperatures are considered extreme cold. Freezing temperatures can cause severe damage to citrus fruit crops and other vegetation. Pipes may freeze and burst in homes that are poorly insulated or without heat. In the North, extreme cold means temperatures well below zero.

Cold Weather Tips...

When the weather turns cold and wind chills dip, newer homes will struggle to maintain temperature and older homes will NOT maintain temperature and the temperature WILL drop while the heating system is working at full capacity.

1. Please raise the temperature in your home, 2 to 4 degrees above your normal setting, this will help maintain a comfortable temperature.  Homes have a hard time catching up on heat when the temperatures drop too low.

2. Take all programmable thermostats out of setback mode and set on a permanent HOLD.

3. If you have a furnace; replace the filter.

4. Keep garage doors closed.

5. Limit opening exterior doors.

6. Make sure air vents and radiators are not blocked or obstructed.

7. If you have a 90%+ furnace and boiler: You must keep the intake and exhaust clear of ice and snow. During these cold temperatures, ice can build up. A 90%+ furnace and boiler have 2 white PVC pipes; an exhaust pipe and an intake pipe that are generally on the side or back of your home. In some instances, they are on your roof, do NOT go on your roof to clear the pipe.

If the temperature in your home is dropping and your radiators are HOT with boiler systems or you have HOT air coming out of your vents with furnaces DO NOT PANIC. Please make sure that your heating system continues to operate.

If the temperatures drop in your home, it will not be able to recover until temperatures rise and the windchill diminishes. Our heating systems cannot overcome temperatures -20 to -30 with wind chill up to -50+. They are sized to operate at 0 degrees outdoor. Put your thermostat on hold 70 degrees or higher.

To help minimize temperature loss you can boil water, make soup, or stews; they help introduce humidity and warmer temperatures into your home. DO NOT USE YOUR OVEN or a GRILL TO HEAT YOUR HOME. Please check on neighbors and elderly residents during these extreme temperatures. Stay warm and safe this week and share this email with any of your family and friends.

Snow

Heavy snow can immobilize a region and paralyze a city, stranding commuters, closing airports, stopping the flow of supplies, and disrupting emergency and medical services. Accumulations of snow can cause roofs to collapse and knock down trees and power lines. Homes and farms may be isolated for days and unprotected livestock may be lost.  The cost of snow removal,repairing damages, and the loss of business can have severe economic impacts on cities and towns.

Ice Storms

Heavy accumulations of ice can bring down trees and topple utility poles and communication towers. Ice can disrupt communications and power for days while utility companies repair extensive damage. Even small accumulations of ice can be extremely dangerous to motorists and pedestrians. Bridges and overpasses are particularly dangerous because they freeze before other surfaces.
 

Ice storms are the result of prolonged periods of freezing rain. Freezing rain occurs if the warm layer in the atmosphere is deep and there is a shallow layer of below freezing air at the surface. The precipitation can begin as either rain and/or snow but becomes all rain in the warm layer. The rain falls back into the air that is below freezing but since the depth is shallow, the rain does not have time to freeze into sleet.

Upon hitting the ground or objects such as bridges and vehicles, the rain freezes on contact. Some of the most disastrous winter weather storms are due primarily to freezing rain.
