Parts of Horry County are already flooding, and the rain isn't leaving for a while

Sorry, Myrtle Beach, the rain isn't letting up anytime soon.

Residents woke up Monday to rain pounding the Grand Strand. At 8:41 a.m., a flood advisory was issued for Horry County, which is also under a flash flood watch, according to National Weather Service in Wilmington forecaster Rachel Zouzias.

Subtropical Storm Alberto spinning in the Gulf Coast, combined with a high-pressure system to the east, is streaming the moisture into the area, Zouzias said.

"The heaviest rain should be [Monday]," Zouzias said. "There’s a plume of tropical moisture streaming in to the area and this with a few other factors are producing heavy rain."

While residents may get a short break from the rain Monday night, Zouzias said it will rain on and off through Thursday.

The flash flood watch is scheduled to last through Tuesday morning, with coastal flooding possible at high tide and rising rivers throughout the week.

At 10:15 a.m. Monday, a flash flood warning was issued for parts of Horry County through 12:15 p.m. Several roads around Horry County flooded due to the rain, according to the South Carolina Highway Patrol. The weather service says almost 3 inches of rain had fallen in parts of the county by 10 a.m. and more rain was expected throughout the day.

Lt. Selena Small with Conway police said in an email that Conway had experienced localized flooding in some low-lying areas.

"Please avoid any standing water and be aware more flooding will occur as the rain continues," she said. "The Conway Police Department and Conway Public Works are monitoring the areas, and will advise any road closures if they occur."

An hourly forecast from the weather service showed no chance of precipitation less than 60 percent through Wednesday.
