DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 400 AM CDT (0900 UTC), the center of Tropical Storm Colin was located near latitude 25.2 North, longitude 87.4 West. Colin is moving toward the north-northeast near 14 mph (22 km/h). A turn toward the northeast with an increase in forward speed is expected today. A rapid northeastward motion is expected tonight and Tuesday. On this track, the center of Colin is forecast to approach the coast of the Florida Big Bend area this afternoon or evening, move across portions of Florida and southeastern Georgia early Tuesday morning, and move near the southeastern coast of the United states later on Tuesday. Reports from an Air Force Reserve Hurricane Hunter aircraft indicate that maximum sustained winds have increased to near 50 mph (85 km/h) with higher gusts. Some additional slow strengthening is possible during the next 48 hours. Tropical-storm-force winds extend outward up to 185 miles (295 km) mainly to the east of the center. The estimated minimum central pressure is 1004 mb (29.65 inches). HAZARDS AFFECTING LAND ---------------------- RAINFALL...Colin is expected to produce rainfall amounts of 3 to 5 inches with isolated maximum totals of 8 inches possible across the northeastern Yucatan peninsula, western Cuba, western to northern Florida, southeastern Georgia, and coastal areas of the Carolinas through Tuesday. STORM SURGE...The combination of a storm surge and the tide will cause normally dry areas near the coast to be flooded by rising waters. The water could reach the following heights above ground if the peak surge occurs at the time of high tide... Indian Pass to Tampa Bay...1 to 3 ft with slightly higher amounts possible in a few locations. Tampa Bay south to Florida Bay...1 to 2 ft. Localized coastal flooding and dangerous surf is possible along the Florida East and Georgia coasts within the Tropical Storm Warning area, as well as in the Tropical Storm Watch area along the Georgia and South Carolina coasts. The deepest water will occur along the immediate coast. 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 to first reach the Gulf coast within the warning area this afternoon, and the Atlantic coast within the warning area by early Tuesday. Tropical storm conditions are possible along the Atlantic coast within the watch area on Tuesday. TORNADOES...A few tornadoes are possible today and tonight across portions of Florida and far southern Georgia. NEXT ADVISORY ------------- Next intermediate advisory at 700 AM CDT. Next complete advisory at 1000 AM CDT. $$ Forecaster Beven NNNN
