PUBLIC INFORMATION STATEMENTA microburst is a downdraft of cold air descending quickly from a collapsing thunderstorm and is a common phenomena with thunderstorms. The down-rushing air hits the ground and spreads out like a fan and can leave a great deal of destruction in it's wake. This is why we say to take precautions from Severe Thunderstorm Warnings similar to Tornado Warnings. The destroyed property doesn't care whether the wind was straight-line or rotating - objects can be lofted and blown about by either!
