Strong wind gusts can toss loose objects, damage weak buildings, break branches off trees and overturn large vehicles. Remember, severe thunderstorms can produce tornadoes. Heavy downpours can cause flash floods and water pooling on roads. If you hear thunder, then lightning is close enough to be dangerous.
