DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ Satellite and surface observations indicate that Colin's circulation is becoming less defined and Colin could lose its status as a tropical cyclone by this afternoon. At 800 AM EDT (1200 UTC), the center of Tropical Storm Colin was estimated to be near latitude 33.6 North, longitude 77.8 West. Colin is moving toward the northeast near 33 mph (54 km/h) and this motion is expected to continue with an increase in forward speed today and tonight. On the forecast track, the center of Colin should move near and parallel to the coast of North Carolina this this morning, then offshore well east of the mid-Atlantic coast later today. 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 increase in strength is expected during the next 24 hours. However, Colin is also expected to lose its tropical cyclone characteristics today. Tropical-storm-force winds extend outward up to 230 miles (370 km) mainly to the southeast of the center. The estimated minimum central pressure is 1000 mb (29.53 inches). HAZARDS AFFECTING LAND ---------------------- RAINFALL: Colin is expected to produce additional rainfall amounts of 1 to 3 inches across eastern North Carolina and central Florida through today. 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... Apalachicola to Naples Florida...1 to 2 ft. Localized coastal flooding and dangerous surf are possible along the Atlantic coast of 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: Tropical storm conditions could occur over portions of the warning area this morning. TORNADOES: A tornado or two will remain possible across parts of the coastal Carolinas today.
