Weather Alert: Winter Storm Warning

Charleston County Emergency Management is continuing to monitor the upcoming winter weather system expected to impact the Lowcountry this weekend. Winter Storm Watches have been upgraded to Winter Storm Warnings for our area.

According to the latest National Weather Service predictions, confidence has increased that accumulating snowfall will occur across Charleston County. Current projections indicate the Charleston area could receive approximately 2 inches of snow, while Awendaw–McClellanville may see closer to 3 inches, with snowfall beginning Saturday afternoon and continuing into early Sunday.

There is a high probability of an Extreme Cold Warning going into effect over the weekend, with windchills being close to 0 degrees in some areas of the County. Coastal winds will also increase, with gusts of 25 to 40 mph possible Saturday night into Sunday.

We encourage people to monitor the forecast from local meteorologists throughout the weekend.

Weather Alert: Monitoring Extreme Cold and Possible Snow

Based on the most recent National Weather Service report, there is a high probability of an extreme cold warning going into effect over the weekend, with windchills being close to 0 degrees in some areas of the County. 

A developing low-pressure system offshore may bring snow to our area. Precipitation could begin as a rain and snow mix Saturday morning, before transitioning to all snow in the afternoon and evening. 

Considerable uncertainty remains regarding the exact timing and amounts, and conditions could evolve quickly. Coastal winds will also increase, with gusts of 25 to 40 mph possible Saturday night into Sunday.

We encourage people to monitor the forecast from local meteorologists throughout the weekend.

King Tides in the Charleston Area December 3-6

King Tide is a commonly used term describing high tides that are higher than normal. They usually occur during a full or new moon or during specific seasons throughout the year. Charleston’s average high tide range is about 5.5 ft., but during a King Tide event, it can reach 7 ft. or higher. 

King Tides can cause flooding in low-lying areas, resulting in road closures on Seabrook Island, as well as the Johns Island and Charleston areas. This is particularly true when a king tide coincides with significant rain and/or wind.

The last dates of predicted King Tides for 2025:

  • December 3 – 6
