Key Points
1
In the Charleston area, minor to moderate tidal flooding is possible around Friday’s high tides—7:23 a.m. and 7:48 p.m.—with additional minor flooding possible Saturday morning and evening. The forecast attributes the risk to onshore winds and the upcoming full moon.

Tropical Storm Fay is forecast to dissipate this weekend over open water as it moves into an unfavorable environment.

In central and southern Alabama, Thursday’s clouds were expected to erode from west to east; highs could struggle to reach 80 degrees in the east while reaching the mid-80s in the west.
The Southeast is heading into a much-needed stretch of pleasant fall weather this weekend, with sunny skies and temperatures climbing into the 70s and low 80s Fox19. But coastal areas face a separate hazard: minor to moderate tidal flooding is possible along South Carolina's coast Friday and Saturday, driven by onshore winds and the full moon's pull on ocean tides National Weather Service.
In the Atlantic, Tropical Storm Fay is weakening over open water and poses no threat to land National Hurricane Center. A second tropical system developing near western Africa also remains far offshore and headed away from the U.S. National Hurricane Center.
Sunny Skies Spread Across Much of the Southeast
After days of clouds and cool conditions, sunshine returns Friday and spreads through the weekend Fox19. Temperatures will rise noticeably — highs reaching the low 70s across parts of the Carolinas and into the 80s from Tennessee to Alabama Fox19. By next week, South Carolina could see highs near 90 degrees Fox19.
Central and southern Alabama saw heavy cloud cover Thursday, but those clouds will clear from west to east National Weather Service. Eastern areas may struggle to reach 80 degrees, while western parts push into the mid-80s National Weather Service. The transition marks the arrival of a crisp, pleasant fall pattern.
Charleston Faces Tidal Flooding Friday and Saturday
The Charleston area and South Carolina Lowcountry will experience minor to moderate tidal flooding around high tides Friday at 7:23 a.m. and 7:48 p.m. EDT National Weather Service. Additional minor flooding is possible Saturday morning and evening National Weather Service. The root cause: a full moon amplifies tidal pull, and strong northeast winds push water up into bays and harbors.
Ron Morales, a warning meteorologist for NWS Charleston, explained that full moons create what forecasters call "king tides." He noted that "every time there's a full moon or a new moon, the tides are going to be higher" National Weather Service. Coastal road closures and brief inundation of low-lying areas are expected, but the flooding will subside as winds ease.
Eastern North Carolina Remains Breezy Before Improvement
Coastal North Carolina is still dealing with a weakening cold-air wedge that will keep conditions breezy and cool through the weekend National Weather Service. Northeast wind gusts are reaching 40 to 50 mph in eastern areas National Weather Service. These strong winds are the main driver of the coastal flooding risk farther south in South Carolina.
Atlantic Tropical Systems Pose No U.S. Threat
Tropical Storm Fay is weakening rapidly over the open Atlantic Ocean southwest of the Azores, with maximum winds of just 50 mph National Hurricane Center. The system will dissipate this weekend in an unfavorable environment and never threaten land National Hurricane Center.
A second tropical disturbance forming near western Africa had a 70 percent chance of developing into a named storm late this week National Hurricane Center. However, forecasters expect any system to remain in the eastern Atlantic and track away from North America National Hurricane Center. The U.S. mainland faces minimal hurricane threat over the next seven days.
