Hurricanes form over a large mass of warm
ocean water during the warmer months.
Air from surrounding areas with higher air
pressure pushes in to the low pressure area.
Then that “new” air becomes warm and moist
and rises, too. As the warm air continues to
rise, the surrounding air swirls in to take its
place.
The whole system of clouds and wind spins
and grows, fed by the ocean’s heat and water
evaporating from the surface.

Hurricane season in the Atlantic Ocean runs
from June 1 to November 30.
The word hurricane comes from the Taino
Native American word, hurucane, meaning evil
spirit of the wind.
The most violent winds and heaviest rains take
place in the eye wall, the ring of clouds and
thunderstorms closely surrounding the eye.
Every second, a large hurricane releases the
energy of 10 atomic bombs.
