Wisconsin Winters

NOAA'S NATIONAL WEATHER SERVICE SAYS: KNOW YOUR WINTER WEATHER TERMS NOAA's National Weather Service urges residents to keep abreast of local forecasts and warnings and familiarize themselves with key weather terminology. Winter Storm Warning: Issued when hazardous winter weather in the form of heavy snow, heavy freezing rain, or heavy sleet is imminent or occurring. Winter Storm Warnings are usually issued 12 to 24 hours before the event is expected to begin. Winter Storm Watch: Alerts the public to the possibility of a blizzard, heavy snow, heavy freezing rain, or heavy sleet. Winter Storm Watches are usually issued 12 to 48 hours before the beginning of a Winter Storm. Winter Storm Outlook: Issued prior to a Winter Storm Watch. The Outlook is given when forecasters believe winter storm conditions are possible and are usually issued 3 to 5 days in advance of a winter storm. Blizzard Warning: Issued for sustained or gusty winds of 35 mph or more, and falling or blowing snow creating visibilities at or below ¼ mile; these conditions should persist for at least three hours. Lake Effect Snow Warning: Issued when heavy lake effect snow is imminent or occurring. Lake Effect Snow Advisory: Issued when accumulation of lake effect snow will cause significant inconvenience. Wind Chill Warning: Issued when wind chill temperatures are expected to be hazardous to life within several minutes of exposure. Wind Chill Advisory: Issued when wind chill temperatures are expected to be a significant inconvenience to life with prolonged exposure, and, if caution is not exercised, could lead to hazardous exposure. Winter Weather Advisories: Issued for accumulations of snow, freezing rain, freezing drizzle, and sleet which will cause significant inconveniences and, if caution is not exercised, could lead to life-threatening situations. Dense Fog Advisory: Issued when fog will reduce visibility to ¼ mile or less over a widespread area. Snow Flurries: Light snow falling for short durations. No accumulation or light dusting is all that is expected. Snow Showers: Snow falling at varying intensities for brief periods of time. Some accumulation is possible. Snow Squalls: Brief, intense snow showers accompanied by strong, gusty winds. Accumulation may be significant. Snow squalls are best known in the Great Lakes region. Blowing Snow: Wind-driven snow that reduces visibility and causes significant drifting. Blowing snow may be snow that is falling and/or loose snow on the ground picked up by the wind. Sleet: Rain drops that freeze into ice pellets before reaching the ground. Sleet usually bounces when hitting a surface and does not stick to objects. However, it can accumulate like snow and cause a hazard to motorists. Freezing Rain: Rain that falls onto a surface with a temperature below freezing. This causes it to freeze to surfaces, such as trees, cars, and roads, forming a coating or glaze of ice. Even small accumulations of ice can cause a significant hazard.

Before Winter Storms and Extreme Cold

Add the following supplies to your disaster supplies kit:

• Rock salt to melt ice on walkways
• Sand to improve traction
• Snow shovels and other snow removal equipment.

Prepare your home and family

• Prepare for possible isolation in your home by having sufficient heating fuel; regular fuel sources may be cut off. For example, store a good supply of dry, seasoned wood for your fireplace or wood-burning stove.
• Winterize your home to extend the life of your fuel supply by insulating walls and attics, caulking and weather-stripping doors and windows, and installing storm windows or covering windows with plastic.
• Winterize your house, barn, shed or any other structure that may provide shelter for your family, neighbors, livestock or equipment. Clear rain gutters; repair roof leaks and cut away tree branches that could fall on a house or other structure during a storm.
• Insulate pipes with insulation or newspapers and plastic and allow faucets to drip a little during cold weather to avoid freezing.
• Keep fire extinguishers on hand, and make sure everyone in your house knows how to use them. House fires pose an additional risk, as more people turn to alternate heating sources without taking the necessary safety precautions.
• Learn how to shut off water valves (in case a pipe bursts).
• Know ahead of time what you should do to help elderly or disabled friends, neighbors or employees.
• Hire a contractor to check the structural ability of the roof to sustain unusually heavy weight from the accumulation of snow - or water, if drains on flat roofs do not work.

Prepare your car

• Check or have a mechanic check the following items on your car:
  • Antifreeze levels - ensure they are sufficient to avoid freezing.
  • Battery and ignition system - should be in top condition and battery terminals should be clean.
  • Brakes - check for wear and fluid levels.
  • Exhaust system - check for leaks and crimped pipes and repair or replace as necessary. Carbon monoxide is deadly and usually gives no warning.
  • Fuel and air filters - replace and keep water out of the system by using additives and maintaining a full tank of gas.
  • Heater and defroster - ensure they work properly.
  • Lights and flashing hazard lights - check for serviceability.
  • Oil - check for level and weight. Heavier oils congeal more at low temperatures and do not lubricate as well.
  • Thermostat - ensure it works properly.
  • Windshield wiper equipment - repair any problems and maintain proper washer fluid level.
• Install good winter tires. Make sure the tires have adequate tread. All-weather radials are usually adequate for most winter conditions. However, some jurisdictions require that to drive on their roads, vehicles must be equipped with chains or snow tires with studs.
• Maintain at least a half tank of gas during the winter season.
• Place a winter emergency kit in each car that includes:
  • a shovel
  • windshield scraper and small broom
  • flashlight
  • battery powered radio
  • extra batteries
  • water
  • snack food
  • matches
  • extra hats, socks and mittens
  • First aid kit with pocket knife
  • Necessary medications
  • blanket(s)
  • tow chain or rope
  • road salt and sand
  • booster cables
  • emergency flares
  • fluorescent distress flag

Dress for the Weather

• Wear several layers of loose fitting, lightweight, warm clothing rather than one layer of heavy clothing. The outer garments should be tightly woven and water repellent.
• Wear mittens, which are warmer than gloves.
• Wear a hat.
• Cover your mouth with a scarf to protect your lungs.

If you are outdoors

• Avoid overexertion when shoveling snow. Overexertion can bring on a heart attack - a major cause of death in the winter. If you must shovel snow, stretch before going outside.
  
  
• Cover your mouth. Protect your lungs from extremely cold air by covering your mouth when outdoors. Try not to speak unless absolutely necessary.
  
  
• Keep dry. Change wet clothing frequently to prevent a loss of body heat. Wet clothing loses all of its insulating value and transmits heat rapidly.
  
  
• Watch for signs of frostbite. These include loss of feeling and white or pale appearance in extremities such as fingers, toes, ear lobes, and the tip of the nose. If symptoms are detected, get medical help immediately.
  
  
• Watch for signs of hypothermia. These include uncontrollable shivering, memory loss, disorientation, incoherence, slurred speech, drowsiness, and apparent exhaustion.
  
  
• If symptoms of hypothermia are detected:
  
  
  • get the victim to a warm location
  • remove wet clothing
  • put the person in dry clothing and wrap their entire body in a blanket
  • warm the center of the body first
  • give warm, non-alcoholic or non-caffeinated beverages if the victim is conscious
  • get medical help as soon as possible.

If you are driving

• Run the engine and heater about 10 minutes each hour to keep warm. When the engine is running, open a downwind window slightly for ventilation and periodically clear snow from the exhaust pipe. This will protect you from possible carbon monoxide poisoning.

• Exercise to maintain body heat, but avoid overexertion. In extreme cold, use road maps, seat covers, and floor mats for insulation. Huddle with passengers and use your coat for a blanket.

• Take turns sleeping. One person should be awake at all times to look for rescue crews.

• Drink fluids to avoid dehydration.
  

• Be careful not to waste battery power. Balance electrical energy needs - the use of lights, heat, and radio - with supply.
  
  
• Turn on the inside light at night so work crews or rescuers can see you.
  
  
• If stranded in a remote area, stomp large block letters in an open area spelling out HELP or SOS and line with rocks or tree limbs to attract the attention of rescue personnel who may be surveying the area by airplane.
  
  
• Leave the car and proceed on foot - if necessary - once the blizzard passes.
