Update as of July 2, 2022 at 11:30 AM: All Tropical Storm Warnings along the immediate South Carolina coastline have been canceled. Tropical Storm Warnings are still in place for offshore waters, as the most intense wind, rain, and wave action will be found there during the next 12 to 24 hours.

A circulation that’s been spinning off the South Carolina coast since Thursday developed into Tropical Storm Colin early Saturday morning.
The center of circulation is now onshore near Georgetown County, Murrells Inlet, and Myrtle Beach where Tropical Storm Warnings are now in effect and encompass much of the Outer Banks of North Carolina. The heaviest rain bands from Colin will remain offshore as the storm moves slowly northeastward through Sunday. However, some coastal locations may receive up to 2 inches of rain causing localized flooding along with the threat of rip currents and rough surf. Locally higher amounts of rainfall are possible in warned areas, with models suggesting as much as 4 inches.
On top of the threat of heavy rain, sustained winds could at times reach 40 mph with gusts over 50. This could cause property damage and power outages so residents are encouraged to take precautions, especially along the Grand Strand. Although impacts are expected to be minor, these hazards should be factored into everyone’s outdoor plans early this holiday weekend.
As the impacts from Colin decrease by Sunday afternoon, a weak cold front will slowly slide through the state into Monday causing scattered showers and storms for the rest of the 4th of July holiday.
