Meteorologists do more than prepare and forecast the weather. Experts from the National Center for Atmospheric Research met recently in Washington, D.C., to advance ideas to prevent fatal car crashes in severe weather. “NBC Nightly News” reports of all deadly atmospheric events, getting into your car and hitting the road, before severe weather episodes, causes the most fatalities. Icing and episodes of fog instantly occur without warning and one out of every four crashes is caused by weather, with more than 7,000 Americans killed annually. Stationary weather stations feed roadway signs, warning of danger ahead and soon cars will have them. Self-contained weather stations will include sensors to measure not only temperature and moisture but black ice, hail and fog. Until then, slow down in rough weather. Fastcast: Cloudy.
