Tropical Storm Colin threatens a wet weekend for Carolinas

Tropical storm warnings have been issued from South Santee River, S.C. to Duck, N.C., including the Pamlico Sound. A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area within 36 hours.

The National Weather Service in Newport/Morehead City reports Colin isn’t expected to gain additional strength and will continue to move northeast on Saturday, likely arriving in the Wilmington area sometime Saturday night.

People along the coastline can expect heavy rain and gusty winds up to tropical storm force over the next 24 hours before the storm pushes back into the Atlantic Ocean and eventually moves away from the United States.

Gov. Roy Cooper alerted people to be aware of conditions over the weekend. While the storm may be more of a rain producer, it’s possible winds could bring down trees and power lines. There could be three inches or more of rain in some spots.

“This storm that formed quickly and rather unexpectedly is a reminder that we all need to be prepared and vigilant during hurricane season,” said Cooper. “If you are enjoying the holiday weekend at the coast, keep a close eye on the weather and be sure to follow directions from local officials and lifeguards.”
