Grand Strand Enters Secondary November Severe Weather Season

Grand Strand residents are entering South Carolina’s secondary severe weather season, which traditionally peaks in November as seasonal atmospheric patterns shift across the region. Local meteorologists are encouraging community members to prepare for potential autumn storms and monitor upcoming seasonal updates.

While spring remains the primary season for severe storms in the Palmetto State, autumn frequently brings high-impact weather patterns. According to historic data from the National Weather Service office in Wilmington, North Carolina, November stands as the second peak month for tornado activity in the coastal and inland region. Data covering 1991 through 2021 shows Horry County experienced 15 non-tropical tornadoes, with strong tornadoes historically touching down during this period.

The autumn severe weather secondary peak is driven by changes in the jet stream, which pushes farther south as colder weather sets in. This movement brings cooler air into the Southeast while increasing winds in the upper atmosphere. When combined with lingering moisture from the Gulf of Mexico, these shifting atmospheric conditions create wind shear, a key ingredient for rotating storms and tornadic activity.

Regional forecasters note that this year's ongoing El Niño pattern will also influence severe weather potential across coastal and Pee Dee communities, likely increasing the overall odds of stronger storm systems moving through the region.

Residents, property owners, and local businesses are advised to review their emergency weather plans and safety protocols as winter approaches. WMBF News will air a special severe weather and seasonal outlook report, "Winter on the Edge," on Thursday, November 5, 2026, at 7:00 PM to provide detailed information on what local communities can expect in the coming months.
