Hurricane season is still here, running from June through November, although it reached its peak in September. Hurricanes start as tropical depressions over the ocean with swirling winds up to 38 mph. From 39 to 73 mph the depression becomes a tropical storm and gains a name. This named storm officially becomes a hurricane when winds reach 74 mph.
Hurricanes occur over the ocean because warm, moist air is abundant over the water.
They use this air as fuel to maintain strength. But they don't last long over land because they lose their source of energy. Meteorologist Ben Pringle can answer your weather questions.
