Rough Surf and Coastal Flooding Expected Along Palmetto State Beaches This Weekend

By Ray Hawthorne

Coastal Flood AdvisoryWeather conditions are forecast to improve this weekend over most of the Palmetto State; however, coastal flooding and rip currents are forecast for residents and visitors along the coast. A cold front passed through much of the state late Thursday night. High pressure over the Great Lakes will supply cooler and less humid conditions over the weekend, but that same high will cause the pressure gradient -- the change in pressure over a distance -- to increase. In addition, the new moon phase recently passed and the perigee (when the moon is closer in its orbit to earth) are strongly favoring...
