The National Hurricane Center is the organization responsible for tracking and reporting to the public and news organizations about the status of hurricanes and tropical systems that threaten (mostly only) North America. Their center is located in Homestead, Florida, where ironically one of the most powerful hurricanes to strike (Hurricane Andrew) made landfall. Makes you wonder, eh?

Here's an excerpt from the NHC website at:

The National Hurricane Center (NHC) maintains a continuous watch on tropical cyclones over the Atlantic, Caribbean, Gulf of Mexico, and the Eastern Pacific from 15 May through November 30. The Center prepares and distributes hurricane watches and warnings for the general public, and also prepares and distributes marine and military advisories for other users. During the "off-season" NHC provides training for U.S. emergency managers and representatives from many other countries that are affected by tropical cyclones. NHC also conducts applied research to evaluate and improve hurricane forecasting techniques, and is involved in public awareness programs.
