It's not official, but it soon will be--Rita is a hurricane. The latest satellite imagery shows a huge and expanding burst of deep convection with very cold cloud tops near the center. The latest UW-CIMSS satellite intensity estimate puts Rita as a 80 mph hurricane with a 982 mb central pressure. Radar imagery from Camaguey, Cuba shows a partially formed elliptical eyewall, open to the north. Long range Miami radar shows a large and expanding area of radar echoes approaching Florida. Rita is a large, impressive Category 1 hurricane, and growing stronger by the hour. The lower Keys are in for a nasty pounding. This may equal or exceed the most damaging hurricane ever in Key West, which I believe was Category 2 Hurricane Georges in 1998, which brought a 4 - 6 foot storm surge and Category 1 winds to the lower Keys, causing $340 million in damage. Expect roof and moderate structural damage to homes and businesses from Rita. Hundred of mobile homes will be damaged or destroyed. Large trees and power poles will be toppled. Damage will be at least $1 billion, which will largely be uninsured losses, since many insurance companies won't insure propery in the Keys.
Where will Rita hit?
Take your pick from today's latest model runs:
GFS: TX/LA border
NOGAPS: Brownsville, TX
UKMET: Galveston
GFDL: Galveston
So, the model trend that had taken Rita towards landfall in western Louisiana has now reversed, to Texas' detriment. Tune in tomorrow morning, the NOAA jet is flying a high-altitude synoptic surveilance mission that should greatly aid the model predictions that will be complete in the morning. I won't start believing the models until I see some runs with the NOAA jet data initializing them.

ACCUWEATHER UPDATE:
Rita is expected to strengthen and should become a hurricane in the next 12 hours. Rita could reach Category 2 strength Tuesday as it crosses the Florida Straits, close to Key West. While there may be some fluctuation in strength as Rita passes north of Cuba Tuesday night, Rita may become a major hurricane as she crosses the southern Gulf of Mexico Wednesday and Thursday. There is concern that Rita could make landfall as a major hurricane along the Texas coast later in the week or early next weekend.
Rita will generally track to the west-northwest Monday night then take a turn more to the west Tuesday as an upper-level ridge of high pressure over Texas expands eastward across the eastern Gulf of Mexico. We expect that this upper ridge of high pressure remains strong and steers Rita on general westerly course across the Florida Straits Tuesday and the central Gulf of Mexico Wednesday and Thursday.
Heavy flooding rain and damaging winds will spread west across the Bahamas Monday night, while hurricane conditions should move into the Florida Keys later Monday night and last into Tuesday. A storm surge of 6-8 feet could affect the Keys, while a 3- to 5-foot storm surge can effect the extreme southeastern Florida Coast and the northwestern Bahamas. There can be a surge of 1-3 feet as far north as Palm Beach, Florida. Tropical storm conditions will spread northwestward across southern Florida Monday night and Tuesday. All interests in South Florida, particularly in the Keys, as well as the southern Gulf and along the Texas and Mexican coasts should now be completing preparations for Rita's onslaught. Rough surf, rip currents and minor beach erosion will be a threat through Tuesday along the East Coast Florida beaches, especially south of Cape Canaveral.
