 DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 500 PM EDT (2100 UTC), the center of Tropical Storm Irma was located near latitude 31.5 North, longitude 84.0 West.  Irma is moving toward the north-northwest near 17 mph (28 km/h), and a turn toward the northwest is expected by Tuesday morning.  On the forecast track, the center of Irma will continue to move over southwestern Georgia tonight and move into Alabama on Tuesday.
Maximum sustained winds have decreased to near 50 mph (85 km/h) with higher gusts.  Continued weakening is forecast, and Irma is likely to become a tropical depression on Tuesday.
Tropical-storm-force winds extend outward up to 415 miles (665 km) from the center.
The estimated minimum central pressure is 985 mb (29.09 inches).
 HAZARDS AFFECTING LAND ---------------------- STORM SURGE:  The combination of a dangerous storm surge and the tide will cause normally dry areas near the coast to be flooded by rising waters moving inland from the shoreline.  The water is expected to reach the following HEIGHTS ABOVE GROUND if the peak surge occurs at the time of high tide...
North of Clearwater Beach to Aucilla River...4 t 6 ft West of Aucilla River to Ochlockonee River...1 to 3 ft Clearwater Beach to Bonita Beach including Tampa Bay...1 to 3 ft
South Santee River to North of Fernandina Beach...4 to 6 ft Fernandina Beach to Flagler/Volusia County line, including the St. Johns River...1 to 3 ft
The deepest water will occur along the immediate coast in areas of onshore winds, where the surge will be accompanied by large and destructive waves.  Surge-related flooding depends on the relative timing of the surge and the tidal cycle, and can vary greatly over short distances.  For information specific to your area, please see products issued by your local National Weather Service forecast office.
WIND:  Tropical storm conditions are expected in portions of the warning area into tonight.
Rainfall:  Irma is expected to produce the following rain accumulations through Wednesday:
South Carolina and north-central Georgia and Alabama into the southern Appalachians...3 to 6 inches with isolated 10 inches. Northern Mississippi and southern portions of Tennessee and North Carolina...2 to 4 inches.
TORNADOES: Isolated tornadoes are possible tonight along the South Carolina coast.
SURF:  Swells generated by Irma are affecting the southeast coast of the United States.  These swells are likely to cause life- threatening surf and rip current conditions.  Please consult products from your local weather office.
 NEXT ADVISORY ------------- Next intermediate advisory at 800 PM EDT. Next complete advisory at 1100 PM EDT.
