Hurricane Irene formed as a result of a tropical wave over the Atlantic Ocean encountering warm waters, moist air, and other favorable conditions that caused it to intensify and organize into Tropical Storm Irene. Continued favorable conditions strengthened this storm into a hurricane.
The remnant low pressure system of Hurricane Irene is centered over Quebec.
At the latest estimate damage from Hurricane Irene was over $10.1 billion in USD.the eye of the hurricane
Hurricane Irene was caused by a strong tropical wave that emerged off the coast of Africa. As moisture from the warm water of the Atlantic Ocean few it it intensified and became better organized, becoming Tropical Storm Irene and later a Hurricane. A semi-permanent high pressure zone over the Atlantic then steered the hurricane on a curved path that took it over a number of islands and up the U.S. east coast.
It has gone up the east coast and is not a hurricane anymore because it has reduced to a post-tropical storm. The remnants are now over the North Atlantic Ocean.
A hurricane over the Atlantic Ocean is simply called a hurricane.
Hurricane Irene will pass over Virginia and Delaware on Sunday. See The Related Link for The Projected Path.
A hurricane requires an enormous supply of water vapor to develop. Such large amounts can only be found over warm ocean water.
A hurricane that forms over the Indian ocean is called a cyclone.
Hurricanes can only develop over warm ocean water. Tornadoes can form on water but usually form on land.
Hurricanes develop from tropical disturbances over warm ocean water. Tornadoes develop from powerful, rotating thunderstorms.
Hurricane Floyd developed over the Atlantic Ocean.
