How did Hurricane Harvey form?

Answer 1

In a word, rapidly. The moist air flowing westward across the North Atlantic Ocean met with the warm waters of the western Caribbean Sea. The perceived tropical wave intensified rapidly, first up to tropical storm forces, then hurricane strength, within six hours' time.

Answer 2

Hurricane Hugo formed in September of 1989 when a cluster of thunderstorms formed off the coast of Africa. Given time and the warm waters of the ocean, the thunderstorms banded together to form the hurricane.

Answer 3

Hurricane Katrina formed as Tropical Depression Twelve over the southeastern Bahamas on August 23, 2005 as the result of an interaction of a tropical wave and the remains of Tropical Depression Ten

Answer 4

Hurricane Harvey formed in a manner similar to many other Atlantic hurricanes. It started as an area of low pressure and thunderstorms new the Cape Verde islands off the coast of Mexico. As it moved west across the Atlantic the system gradually became stronger and more organized, becoming Tropical Storm Harvey on August 17. It moved into the Caribbean and soon encountered wind shear that caused it to degenerate back into a tropical wave on August 19. After crossing the Yucatan Peninsula and emerging into the Bay of Campeche the wave soon reorganized into a tropical depression and then strengthened into a tropical storm. Harvey then began to intensify rapidly in an environment of warm water and little wind shear. It quickly reached hurricane status. As of the afternoon of August 24, Hurricane Harvey is expected to continue to gain strength and strike the Texas coast at a major hurricane.

Answer 5

Hurricane Harvey formed from a combination of warm ocean waters in the Atlantic Ocean, low wind shear (change in wind speed or direction with altitude), and atmospheric instability. These conditions allowed a tropical disturbance to intensify into a tropical storm and eventually a hurricane.

Answer 6

Hurricane Katrina did not form over land. Katrina formed over the Atlantic Ocean near the Bahamas and was moved over land by wind currents.

Hurricanes cannot form over land.

Answer 7

Hurricane Katrina first formed over the Bahamas.
