Tropical storm remnants passing through Hilton Head area. Here’s the forecast

The first named tropical cyclone of 2026, Tropical Storm Arthur, formed yesterday in the Gulf of Mexico and made landfall on the Texas coast.

The storm is now post-tropical, but the National Hurricane Center predicts its remnants will move over South Carolina and the Lowcountry Thursday evening and overnight.

Although Arthur is no longer a tropical storm, it maintains the potential for severe weather, gusty winds and heavy rainfall. Its effects on the Lowcountry are contingent upon where it goes.

Here’s where the forecast stands today:

What’s coming to the Lowcountry Thursday?

The center of Arthur’s remnants is predicted to move over South Carolina between the Midlands and the Upstate overnight. The remnants maintain some circulation, which is typically seen in a developed tropical storm or hurricane.

Pockets of thunderstorms and heavy rain are likely to move into the Lowcountry in the late afternoon and continue overnight, according to the National Weather Service.

The National Oceanic and Atmospheric Administration’s Storm Prediction Center gives the Lowcountry a 10% chance of thunderstorms today from 12 p.m. to 4 p.m. and a 40% chance from 4 p.m. to 8 p.m.

While the tornado threat for the area is low, one is nonetheless possible alongside the thunderstorms, according to the NWS. Damaging wind gusts are possible overnight. The NWS predicts gusts of around 25 mph, but this may change depending on Arthur’s track.

The Lowcountry is under a marginal risk for excessive rainfall. NOAA’s GFS weather model predicts around a half inch or more rainfall in the Lowcountry through Saturday, but totals could be higher if Arthur’s remnants track closer or a strong thunderstorm blows through.

What about Friday and the weekend?

Arthur’s remnants will head offshore by Friday afternoon. The storm may regain some strength, but the forecast said it won’t return to land.

Showers and thunderstorms will continue through the evening on Friday. Wind gusts around 30 mph are possible throughout the day, according to the NWS, and dangerous heat is possible Friday with a heat index value of 102 on Hilton Head Island.

The weekend marks a return to sunny and hot conditions. Saturday and Sunday are both expected to be partly sunny with a high of 92 degrees.

Both Saturday and Sunday have a 20% chance of showers and thunderstorms in the afternoon.

The forecast is likely to change depending on Arthur’s track over South Carolina. To stay informed, view the NWS’s forecast here.
