Jasper and Beaufort Counties, SC – The National Weather Service (NWS) Charleston SC has issued a coastal flood advisory for Coastal Jasper and Beaufort Counties, effective until 10 a.m. on Tuesday. The advisory was released at 6:04 a.m. and warns residents and travelers of expected saltwater inundation up to one half foot above ground level along shorelines and tidal waterways, following high tide anticipated at approximately 8:33 a.m. at Fort Pulaski.
The NWS cautions that saltwater inundation may affect the area 1 to 2 hours before and after high tide, potentially impacting various roads. Residents and visitors are urged to allow extra time for travel as some roads may be closed due to rising water levels. It is advised not to drive around barricades or through water of unknown depth.
Property owners in flood-prone areas should move to higher ground if necessary. If evacuation is recommended, residents should securely lock their homes before leaving. Before exiting, if time permits, it is suggested to disconnect utilities and appliances. Caution is advised against entering basements or rooms with submerged electrical outlets or cords. In the event of witnessing sparks or unusual sounds such as buzzing or crackling, immediate evacuation is required.
Authorities warn that entering floodwaters poses significant risks; even six inches of moving water may knock an individual off their feet, while twelve inches can sweep away most vehicles. Hydroplaning, which occurs when vehicles slide uncontrollably on wet roads, can happen due to water buildup in front of tires. Key factors contributing to hydroplaning include tire tread, vehicle speed, and water depth.
The current high tide situation arises from the gravitational pull of the sun and moon, commonly resulting in higher tides during full or new moons. Additionally, extended northeast winds of 15-20 mph can elevate coastal water levels, with ocean current interactions, particularly with the Gulf Stream, contributing to increased water levels during high tides. It is also important to note that rainfall coinciding with high tide exacerbates flooding due to limited drainage capacity.
Minor coastal flooding is expected to persist for several days during the high tide cycles as the advisory serves as a notice of lower impact flooding primarily affecting roads in coastal areas.
