Accurately forecasting winter weather is a complicated process. It starts with a wide network of observing systems such as satellites, Doppler radars and automated surface observing systems. Computer forecast models take this information and estimate what will happen next.
How do you know when a winter storm is coming?
Watch for winds blowing from the east. Warm, moist air from the Gulf of Mexico rises as it flows north, producing snow if there’s frigid air at ground level. Clouds rolling in from the southwest indicate approaching storms.
How do ice storms affect humans?
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.

Tips To Staying Safe And Warm During Ice Storm Recovery
- Stay inside and dress in warm, layered clothing.
- Close off unneeded rooms.
- When using an alternative heat source, follow operating instructions, use fire safeguards and be sure to properly ventilate.
- Stuff towels and rags underneath doors to keep the heat in.
How much ice does it take to cause power outages?
According to most meteorologists, just one quarter of an inch of ice accumulation can add about 500 pounds (230 kg) of weight per line span. Damage from ice storms is easily capable of shutting down entire metropolitan areas.
How much ice does it take to knock power?
Half an inch of ice can add as much as 500 pounds to a power line, and damage can begin when accumulations exceed a quarter of an inch. Additional weight can be applied if a tree branch breaks off and rests on it, increasing the potential for the power line to come down.
What states have ice storms?
Places that could be hit with a glaze to two-tenths of an inch of ice include Oklahoma City and Tulsa, Oklahoma; Springfield, Missouri; Evansville, Indiana; Memphis, Tennessee; Louisville, Kentucky; Huntington and Charleston, West Virginia; and much of Virginia.
