Hurricane Alley Tropical Weather
Basic InformationHurricane Alley is an area designated by weather forecasters where most hurricanes that hit the United States form. Find out more about this area of unsettled weather.
Just like there is a tornado alley where most tornadoes occur, there is one for hurricanes in the Atlantic Ocean where most hurricanes that affect the United States and Caribbean.
Weather forecasters know that hurricane season typically starts in June, and ends in November. During these times, the waters of the Atlantic just north of the equator are at their warmest.

Low pressure weather systems that form in the areas need the warm water in order to turn into tropical storms and powerful hurricanes. The waters at the beginning of the season in this area are at their warmest. This is when storms from the west coast of Africa and go into the Atlantic Ocean and have the potential to turn into hurricanes. If other weather conditions are right, then a hurricane can easily form in in these areas.
Most storms track to the west and some get pushed out to sea to the north, while others take a more direct path towards the United States and other nearby places. One thing you should also understand is that the waters in this area can get cooler after a hurricane moves through. For example if Hurricane "A" forms and moves across the Atlantic as a powerful storm, it will churn up the waters around it bringing cooler waters up from the deep ocean.
If another storm tries to form behind it, it will have a hard time doing so even in peak hurricane season because of the cooler waters. I've always thought this was a fascinating weather fact. This is why some seasons start out active, then quiet down. Read more about How do Hurricanes Form.
