Charleston, SC Issues Coastal Flood Advisory Amid High Tide Risks
The National Weather Service (NWS) in Charleston, SC, has issued a coastal flood advisory effective Thursday from 3 p.m. to 7 p.m. for Coastal Colleton and Charleston County. This advisory comes as high tide is expected to occur around 5:13 p.m. on the same day, with forecasts estimating inundation levels of up to one half foot above ground level along shorelines and tidal waterways.
The NWS warns that saltwater inundation may be possible one to two hours before and after the high tide, which could lead to impassable roads. Travelers in the area are advised to allow extra time for travel, as some roads may be closed. It is crucial not to drive around barricades or through unknown depths of water, as these actions can be dangerous.
Residents living in flood-prone areas or camping in low-lying zones are urged to seek higher ground immediately. In the event of evacuation orders, individuals should comply promptly. Residents should ensure their homes are securely locked and, if possible, disconnect utilities and appliances before leaving.
During the advisory, individuals are advised to avoid basements or rooms that may have submerged electrical outlets or cords. If any sparks or buzzing sounds are heard during flooding, individuals should evacuate immediately and not enter water that could carry an electric current. It is important to note that even as little as six inches of moving water can knock an adult off their feet.
If anyone finds themselves trapped by moving water, they should seek the highest possible point and contact emergency services by calling 911. The risk of flooding significantly increases with intense rainfall, particularly in low-lying and flood-prone areas. The NWS emphasizes the importance of avoiding driving through any water on the road, even when it appears shallow, as just 12 inches of rushing water can sweep a vehicle away.
Hydroplaning is also a concern during these adverse conditions, occurring when a vehicle slides uncontrollably over wet roads due to water pressure creating a barrier between the tires and the road surface.
The emergency advisory will remain in effect until 7 p.m. on Thursday as authorities monitor conditions closely. Residents are urged to stay informed about changing weather patterns and adhere to safety measures to minimize risks during this advisory.
