Rainfall, Storm Surge, Wind & Coastal Flooding
The storm is anticipated to bring 6-10 inches of rain. There may be isolated areas that receive as much as 12 inches. Coastal flooding is anticipated.
Tropical storm-force winds (40-73 mph) are expected from Thursday night into Saturday morning, with the most severe impacts anticipated late morning or afternoon on Friday. Isolated tornados are possible.
The storm surge warning estimates 4-7 foot inundation levels. Inundation is the total water level that occurs on normally dry ground as a result of the storm tide, and is expressed in terms of height of water, in feet, above ground level.
The tide levels and the wind direction at the time the storm reaches Kiawah will greatly influence coastal flooding and storm inundation levels. Winds and tide can push water inland or pull water away. While the pond system is designed to manage rainfall events, it is not designed to manage storm inundation. In the event of storm surge inundation, members should stay in their homes until waters have receded. Eventually tides will pull water away from the island and out through the pond system. The ponds do not have a pump system and rely on low tides for drainage.
Tide Levels on Friday, Sept. 30
5:26 a.m. low tide | 11:55 a.m. high tide | 6:21 p.m. low tide
Be advised of rip currents and stay out of the water. With increasing winds, water levels may remain high, even at low tide cycles.
