Hurricanes are tropical cyclones with winds that exceed 64 knots (74 mi/hr) and blow counterclockwise about their centers in the Northern hemisphere, (clockwise in the Southern hemisphere).
Hurricane season typically extends from June through November, when water temperatures in these regions are relatively high (greater than 26.5 C). Most hurricanes occur in late summer and early fall, i.e., August and September. Hurricanes are larger than thunderstorms and tornadoes but smaller than mid-latitude cyclones The primary components of a hurricane include:
There is an average of 84 tropical storms and 45 hurricanes / typhoons globally per year. Roughly nine named storms develop per year in the tropical Atlantic and Gulf of Mexico, six of which typically become hurricanes; two of which become intense hurricanes (sustained winds exceeding 130 mph or 209 km/hr).
