Hurricane Isaias is a Category 1 Hurricane in the Gulf. While it is forecast to target the northern Gulf Coast tonight through Friday, its massive moisture field and expansive track mean certain impacts are coming to South Carolina starting late Friday and lasting through Sunday midday.
The storm is drawing up an incredible amount of tropical moisture and will dump heavy rain far away from its center. No matter the exact landfall point, all areas of South Carolina will feel its impact.
South Carolina ETV and Public Radio Chief Meteorologist Tim Miller is keeping a close eye on Isaias and what it could mean for the state. As of Thursday afternoon:
Statewide rainfall and flooding risks
Widespread rainfall of up to two to four inches is expected across the state with a narrow corridor of four-plus inches possible along the coast, depending on the storm’s final speed.
Flash flooding and urban flooding are a concern, especially in low-lying, coastal and poorly drained areas. Locations that would typically flood during a heavy summer thunderstorm is the general rule.
Regional breakdown and severe risks
In the Lowcountry and along the coast, heavy rain and strong, gusty winds are anticipated starting late Friday through Sunday midday. Two to four inches of rain is possible with isolated higher amounts.
There is also the the risk for coastal flooding, dangerous marine conditions, and life-threatening rip currents. Isolated tornadoes are a real threat by Saturday afternoon through the early hours of Sunday morning.
In the Pee Dee, heavy tropical downpours and gusty winds will move in by Saturday. There is also the potential for localized flash flooding in low-lying areas, and residents should keep an eye out for minor river flooding.
In the Midlands, periods of heavy rain and breezy conditions are expected with up to two to four inches of rain possible.
While the highest wind threats stay closer to the storm's track, the Midlands will need to stay with SCETV on our Facebook page as we watch radar closely for rotating storms capable of producing brief, isolated tornadoes Saturday afternoon through early Sunday morning.
And despite its inland location, the Upstate and mountain foothills are facing a significant threat of heavy rain and flash flooding midday Saturday through Sunday afternoon. Up to 3 inches of rain (locally higher) could trigger quick-rising creeks and streams. It is important to note, however, the impacts of Isaias will not be anywhere close to that of Helene.
Chief Meteorologist Tim Miller will continue to provide updates on the storm throughout the weekend. Keep track of Isaias online with SCETV Weather and on our social media channels.
