Summer storms are usually intense and short. You can see them blowing in, and then all heck breaks loose, and then a half hour later it could be sunny again. The micro bursts are the scariest, there is really no escape if you are camped when they hit. One hit our local park last summer the morning that I was leaving with my wife for our canoe honeymoon. We went out to the park and were shocked by the devastation. My sister in laws 27 foot trailer was destroyed by several healthy big poplar trees that were torn up by the roots! Usually the poplars break off half way up or something, but this time, they were just pulled right out. The entire episode was only about an hour long, and the sun came out afterwards, but for the poor folks in the park, it was a nightmare. Several people were in their trailers as trees fell around and on them.
