News Summary
A coastal flood advisory has been activated for Charleston and Coastal Colleton Counties, predicting water levels to rise to 7.4 feet above Mean Lower Low Water. Residents are advised to prepare for potential flooding, especially during high tide. The National Weather Service warns that inundation could affect roads and low-lying areas, urging precautionary measures for safety. Travelers should expect delays due to these conditions.
Charleston, SC – A coastal flood advisory has been issued for Charleston and Coastal Colleton Counties starting at 6:31 p.m. on Sunday, lasting until 9 p.m. The National Weather Service (NWS) anticipates water levels to reach between 7.2 to 7.4 feet above Mean Lower Low Water at Charleston, coinciding with the expected high tide around 7:22 p.m.
Residents and travelers in these areas should prepare for potential inundation levels of up to one half foot above ground level along shorelines and tidal waterways. Saltwater inundation may occur one to two hours before and after high tide, raising concerns that many roads may become impassable due to flooding.
To mitigate risks, travelers are encouraged to allocate additional time for their journeys, considering that some roads may be closed as conditions worsen. NWS officials advise against driving around barricades or through water of unknown depth. Those residing in flood-prone areas are urged to take necessary precautions to protect their property.
Individuals living or camping in low-lying flood-prone areas should move to higher ground immediately in light of potential flooding. If an evacuation order is issued, residents must evacuate at once and secure their homes by locking doors and windows. When time allows, it is recommended to disconnect utilities and appliances before leaving.
Safety measures are essential, particularly regarding electrical hazards during flooding. Residents should avoid entering basements or rooms where water has submerged any electrical outlets or cords. If any sparks, buzzing, crackling, or popping noises are detected, the affected individual is advised to evacuate immediately.
In addition to flood risks, the public is cautioned to steer clear of all water that may be electrically charged, as well as to avoid attempting to walk through floodwaters. Even just six inches of moving water can knock an individual off their feet, while 12 inches can sweep away most vehicles. Hydroplaning is another potential danger during flooding, which occurs when a vehicle loses traction due to water accumulation in front of its tires. This lack of control can result in sliding off the road surface, posing further hazards to drivers.
The NWS urges locals and travelers to stay informed about the weather situation as the advisory continues and to heed any further instructions or warnings shared by local authorities.
Historically, coastal flood advisories in the Charleston area have prompted similar precautions, particularly in low-lying regions vulnerable to frequent inundation. Residents are well-advised to stay alert, especially during periods of high tide when over-topping waves can exacerbate flooding conditions.
As Charleston and Coastal Colleton Counties brace for the impending high tide, the NWS is committed to keeping the public informed about any developments regarding water levels and safety measures. Proper preparation and awareness can help mitigate potential damages and ensure the safety of residents and travelers alike in the area.
