2009 hurricane forecast

How and if global warming influences hurricane formation is still a matter of genuine scientific debate. In recent years, scientists have at least identified several factors -- from the extent of rainfall in Africa to the presence or absence of El Nino conditions in the Pacific -- that help them predict the intensity of a hurricane season ahead of time. Here's what the two most prominent forecasters have to say:
The federal government has predicted a "near normal" hurricane season for the Atlantic with a 25% chance of above-normal outbreaks and 25% chance of below-normal outbreaks -- though overall, forecasters expressed a greater degree of uncertainty this year than they have in past years.
The National Oceanographic and Atmospheric Administration's predicts a 70% chance of:

• Named storms: 9-14
• Hurricanes: 4-7
• Major hurricanes: 1-3

The other major forecaster in the U.S., the University of Colorado, recently revised down its expectations for the 2009 Atlantic hurricane season:

• Named storms: 12
• Hurricanes: 6
• Major hurricanes: 2

Further, the Colorado forecasters predicted the following probabilities that a major hurricane could strike the U.S., all of which are about average for the past century:

• Entire U.S. coastline: 54%
• U.S. East Coast (including peninsula Florida): 32%
• Gulf Coast (from the Florida Panhandle westward to Brownsville, Texas): 31%
• Caribbean: Average

Forecasters warn that the number of storms and their intensity is only one key determinant of risk of property damage and loss of life: The biggest factor is who lives in harm's way and how well they prepare. Some 35 million U.S. residents live in hurricane-prone regions, and experts urge them to prepare.
When those storms do come, they will be given names. Tropical cyclones are given names when they achieve tropical storm strength, with sustained winds of at least 39 mph. Hurricanes are tropical storms that have sustained winds that exceed 74 mph, and major hurricanes have sustained winds that exceed 111 mph.
Here are the tropical storm and hurricane names for 2009:
