[00:00.00]Fortunately, a hurricane does not last long, about 20 to 30 minutes on the average. [00:07.70]Usually it destroys an area about 16 miles long and the great damage [00:13.36]that it does in one place lasts only about 30 seconds. [00:17.54]Hurricanes normally occur on hot, humid days but not necessarily in the summer. [00:23.82]More than 200 hurricanes strike in the United States every year. [00:29.02]It is not possible to predict when a hurricane will strike although the U.S. [00:34.91]Weather Bureau gives storm warnings when conditions are right to cause a hurricane. [00:40.37]The safest place to be if a hurricane seems likely is in some underground area such as a cellar or a basement.
