Winter Storm Facts
Know the Terms
Winter Storm Watch - Indicates that severe weather may affect your area.
Winter Storm Warning - Indicates that a winter storm is occurring, or will occur in your area.
Freezing Rain - Rain that freezes when it hits the ground creating a coating of ice on roads, walkways, trees, and power lines.
Sleet - Turns to ice pellets before reaching the ground. Sleet also causes moisture on roads to freeze and become slippery.
Wind Chill - Calculation of how cold it feels outside when the effects of temperature and wind speed are combined.
Blizzard Warning - Sustained winds or frequent gusts to 35 miles per hour or greater and considerable amounts of falling or blowing snow are expected for a period of three hours or longer.
Frost/Freeze Warning - Below freezing temperatures are expected.
Heavy Snowfalls - Snow accumulation of four inches in a 12- hour period or six inches in a 24-hour period.
Ice Storms - Occur when freezing rain falls from clouds and freezes immediately when it touches the ground.
Frostbite - A condition where localized, sometimes permanent, damage occurs to skin and other tissue due to extreme cold. Symptoms of frostbite include a loss of feeling and a white or pale appearance in extremities such as fingers, toes, tip of the nose, and ear lobes.

Actions to Consider
If in a Vehicle
Did You Know...
70 percent of winter deaths related to snow and ice occur in automobiles. Also a blanket or rug under the front of a tire will help "unstick" a vehicle by increasing traction. It can be used on walkways to prevent slipping and it provides traction under wheels of vehicles stuck in ice and snow.
