Very large hail can damage property, break windows, dent vehicles and cause serious injury. Very strong wind gusts can damage buildings, down trees and blow large vehicles off the road. Intense lightning is likely with any thunderstorm that develops. Remember, severe thunderstorms can produce tornadoes. Heavy downpours can cause flash floods and water pooling on roads.
