Charleston residents face a tricky start to Patriot Day as a Coastal Flood Advisory remains in effect until noon Wednesday. Drivers should expect standing water on low-lying roads, especially along U.S. 17 and near the Ashley River.
According to the National Weather Service in Charleston, the combination of high tide and persistent onshore winds is pushing water inland. Motorists are urged to avoid flooded routes and give themselves extra travel time if heading to morning Patriot Day remembrance ceremonies.
Conditions will quickly improve once the advisory lifts. Skies turn mostly sunny Wednesday with highs near 83 degrees. Breezes from the north will hold humidity in check, creating a more comfortable feel across the Lowcountry. By Thursday, dry air lingers, and temperatures remain steady in the low 80s.
Weekend plans should be safe from weather interruptions. Friday and Saturday both bring full sunshine and highs near 83. Nights remain mild, with temperatures dropping into the upper 60s. Sunday continues the trend with clear skies, offering excellent conditions for outdoor gatherings, sports, and travel.
The flood advisory is expected to be the week’s only weather disruption. Still, officials urge residents in flood-prone zones to monitor updates and avoid driving through high water. Sunny conditions dominate after Wednesday, bringing a welcome stretch of calm fall weather.
