La Duradero is a tropical weather event that happens when strong western tropical winds meet northern eastern winds at a low pressure zone in the mid Atlantic. Circular winds form around the low, encasing it and holding it in one place. Moisture and heat get easily trapped inside, creating a tropical hotspot ranging from 1,000- 2,500 miles wide. The event often causes intense hurricanes all year round, even in off season (December-May) many major hurricanes can form.
