Key Messages

- 1) A significant, multi-day coastal flooding event will continue this week.

- 2) Strong northeast flow through early week will result in several hazards including rip currents, high surf, and beach erosion.

- 3) Dry conditions will continue through the week before gradually warming up by the end of the week.

Discussion

KEY MESSAGE 1: A significant, multi-day coastal flooding event will continue this week.

Astronomical tides will continue to rise into early this week due to the upcoming full moon (10/26) and the lunar perigee (10/28). Large tidal departures are ongoing, and with an extended period of strong northeast flow this weekend and into next week, departures will increase in magnitude. The combination of the highest astronomical tides of the year and persistent strong northeast flow will result in a multi-day moderate to major coastal flooding event for the entire southeast GA/SC coast.

Monday Morning: The highest tide level of the event is forecast to occur around 8 AM, with 7.9-8.1 ft MLLW forecast at the Charleston Harbor and 10.0-10.2 ft MLLW at Fort Pulaski. A Coastal Flood Warning is in effect for Charleston and Coastal Colleton Counties, as this tide is forecast to reach major flood levels. Elsewhere along the coast a Coastal Flood Advisories are in effect, including Tidal Berkeley.

Rest of This Week: Coastal flooding is forecast to occur with the Tuesday, and Wednesday morning high tide cycles, with minor flooding possible through the end of the week. During these cycles, it is possible that the Charleston Harbor could exceed moderate flood stage. Winds will slightly relax heading into this week, leading to lowering tidal departures. Coastal Flood Advisories will be needed.

KEY MESSAGE 2: Prolonged gusty northeast flow through late week will result in several hazards including rip currents, high surf, and beach erosion.

Rip Currents: Gusty northeast winds, long-period swell, and ongoing wave action will continue to support dangerous rip currents along all southeast SC/GA beaches. A High Risk for rip currents is in place for all area beaches through Tuesday. An enhanced risk of rip currents could continue through the rest of week. Of note: Saturday, October 31 marks the end of the 2026 surf season and the final routine issuance of the Surf Zone Forecast.

Aviation

VFR Conditions are expected to prevail through the forecast with gusty northeasterly winds persisting during the day. Winds should be slightly lower than the past few days with gusts up to 20 knots possible. Winds should relax tomorrow night to around 5 knots or less.

Extended Aviation Outlook: Breezy north-northeast winds are expected at KCHS/KJZI/KSAV daily through late week. Otherwise, there are no high confidence concerns.&&
