When driving into a hailstorm, find a safe place to pull over and turn your car so the hail is hitting the windshield.Surfaces may become slick, so use caution if you’re outside.Hail of any size can be dangerous when pelted in high winds. If weather conditions are prime for a storm, move cars, boats, RVs, and lawn and patio furniture into a covered area.But considering the fact that large stones can fall at speeds faster than 100 miles per hour, it’s important that you cover your noggin and learn what to do when hailstorm conditions are present. In fact, the costliest thunderstorm event in U.S. Hail most commonly causes damage to property, vehicles (remember all of those “Hail Sales” at your local dealership?) and crops more than $1 billion in damage each year. The cold air causes the raindrops to freeze into small blocks of ice. These hard, frozen nuggets are formed when raindrops pass through a belt of cold air on their way to earth. The sky is falling! The sky is falling! Oh, wait - that’s just hail.
