1. Rough surf and rip currents are likely to continue along the North Carolina coast through Sunday.

2. Scattered areas of heavy rainfall may result in localized flash flooding across coastal portions of North Carolina through Sunday morning.

CHANGES WITH THIS ADVISORY: The Tropical Storm Warnings for the North Carolina coast and the Pamlico Sound have been discontinued. SUMMARY OF WATCHES AND WARNINGS IN EFFECT: There are no coastal watches or warnings in effect.

WIND: Gusts to tropical storm force in squalls are possible across portions of coastal North Carolina tonight.

RAINFALL: Colin will continue to produce locally heavy rainfall across coastal portions of North Carolina through Sunday morning, where an additional 1 to 2 inches of rainfall is possible. This rainfall may result in localized areas of flash flooding.

SURF: Swells generated by Colin are affecting portions of the North Carolina coast. These swells could cause life threatening surf and rip current conditions. Please consult products from your local weather office.

At 1100 PM EDT (0300 UTC), the center of Tropical Depression Colin was located near latitude 34.4 North, longitude 77.8 West. The depression is moving toward the northeast near 7 mph (11 km/h). A slightly faster northeast to east northeast motion is expected during the next day or so. On the forecast track, the center of Colin or it remnants is expected to move northeastward along or just inland of the North Carolina coast through Sunday afternoon. Maximum sustained winds have decreased to near 35 mph (55 km/h) with higher gusts. Additional weakening is likely, and Colin is expected to degenerate to a remnant area of low pressure later tonight or on Sunday. The system is expected to dissipate completely Sunday night or Monday. The estimated minimum central pressure based on surface observations is 1014 mb (29.95 inches).

Colin continues to become less organized, with only minimal convection currently occurring and surface observations showing that the circulation is losing definition. Offshore buoys have reported winds of 20-25 kt for the past several hours, suggesting that there are no tropical-storm-force winds left over water. Based on this, Colin is downgraded to a tropical depression, and all of the coastal warnings are discontinued.

The current weakening trend is expected to continue due to increasing northwesterly vertical wind shear and dry air entrainment, and Colin is now forecast to degenerate to a remnant low pressure area within the next 12 h. The remnants are forecast to dissipate after 24 h as they merge with a frontal system over the northwestern Atlantic.

The initial motion is an somewhat uncertain 055/6 kt. Colin or its remnants should continue to move generally northeastward through eastern North Carolina for the next 12-18 h, and then move out over the Atlantic before merging with the aforementioned frontal system.
