5:00 pm EDT August 25, 2005: NHC Advisory: Katrina is Now a Hurricane

Tropical Storm Katrina becomes Hurricane Katrina, according to the latest advisory issued by the National Hurricane Center (NHC). Hurricane Katrina now has maximum sustained winds of 75 mph, making it a Category 1 hurricane. The NHC expects that Katrina could strengthen before making landfall, and then weaken as it moves inland across South Florida through Friday. Models indicate that Katrina will move slight south of due west for next 12 hours, before moving northwest than north after 48 hours. NHC models agree on westward motion for next 36 hours, but continue to diverge significantly after that. One model takes Katrina northeast after 72 hours across the Florida panhandle, while three other models take Katrina significantly westward, indicating Katrina landfall between Mobile, Alabama and Grand Isle, Louisiana. However, the NHC gives two of the three models indicating a westward turn “less weight” because they have not been accurate over past 24 hours. Other aspects of the NHC Advisory include:
bullet Location: 26.1 N, 79.9 W
bullet Direction and Speed: West at near 6 mph
bullet Estimated Central Pressure: 985 mb
bullet Probability that in the next 69 hours, Katrina’s eye will pass within 75 miles of:
bullet West Palm Beach, FL: 99 percent
bullet Panama City, FL: 14 percent
bullet Gulfport, MS: 8 percent
bullet New Orleans, LA: 7 percent [National Hurricane Center, 8/25/2005; National Hurricane Center, 8/25/2005; National Hurricane Center, 8/25/2005]
