Officially, a hurricane is a type of tropical storm with
strong winds circulating around an extreme low-pressure area
with wind speed that reaches or exceeds 74 mph.
A hurricane's spiraling wind and rain bands can extend hundreds
of miles from its center or eye. As the storm approaches land,
tornadoes may form around its outer edges.
The most dangerous part of a hurricane is the storm surge,
the large dome of water that floods the coast as the storm
makes landfall. This surge is the greatest threat to life.
Even if the storm strikes at low tide, the water level might
reach as high as 20 feet at the shoreline. Flooding is also
caused by the heavy rains as the hurricane moves inland.
Most hurricanes start in the tropical waters of the Atlantic
Ocean, the Caribbean Sea and the Gulf of Mexico. Although
the official “hurricane season” runs from June
1 to November 30, most hurricanes strike in August, September
and October.
