DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 400 PM CDT (2100 UTC), the center of Tropical Storm Colin was located near latitude 28.8 North, longitude 85.5 West. Colin is moving toward the north-northeast near 23 mph (37 km/h). A northeastward motion at a faster forward speed is expected tonight and Tuesday. On this track, the center of Colin is forecast to move onshore of the Florida Big Bend area this evening, then move across northern Florida and southeastern Georgia through early Tuesday morning, and move near or over the southeastern coast of the United States Tuesday. However, it's important to note that the strongest winds and heaviest rains are well removed from the center. Maximum sustained winds are near 50 mph (85 km/h) with higher gusts. Some strengthening is forecast on Tuesday and Tuesday night. Tropical-storm-force winds extend outward up to 230 miles (370 km) to the southeast of the center. A NOAA coastal marine observing site at Venice, Florida recently reported sustained winds of 44 mph (70 km/h) with a gust to 60 mph (96 km/h). The estimated minimum central pressure is 1002 mb (29.59 inches). HAZARDS AFFECTING LAND ---------------------- RAINFALL: Colin is expected to produce rainfall amounts of 3 to 6 inches with isolated maximum totals of 8 inches possible across the northeastern Yucatan peninsula, western Cuba, 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 are possible along the Atlantic coast from Florida to North Carolina within the tropical storm warning area. 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: Brief squalls with winds to near tropical storm force will be moving through portions of South Florida through this evening. Tropical storm conditions will continue across portions of the warning area along the west coast of the Florida peninsula through the evening. Tropical storm conditions are expected to reach the warning area along the Atlantic coast by overnight tonight. TORNADOES: A few tornadoes are possible today and tonight across portions of Florida and far southern Georgia. NEXT ADVISORY ------------- Next intermediate advisory at 700 PM CDT.
