Calcasieu Parish, Louisiana — The National Weather Service (NWS) in Lake Charles, Louisiana issued a flash flood warning for Calcasieu Parish on Tuesday afternoon, alerting residents to the potential dangers posed by rapidly rising water due to heavy thunderstorms. The warning remains in effect until 4:30 p.m. Central Daylight Time.

According to meteorologists, Doppler radar detected intense thunderstorms producing significant rainfall across the affected area as of 2:36 p.m. CDT. Estimates indicate that 1 to 2 inches of rain had already fallen by early afternoon, with an additional 1 to 3 inches possible within the warning period. The anticipated rainfall rate—between 1 and 3 inches in a single hour—raises concerns about sudden flooding in vulnerable locations.

Flash flooding, a rapid and powerful overflow of water onto normally dry land, is particularly hazardous because it can develop quickly, often with little warning. The NWS reports that low-lying areas, creeks, streams, urban neighborhoods, highways, and underpasses are especially susceptible. Poor drainage systems can worsen the situation, causing water to accumulate and create dangerous travel conditions.

Officials urge all motorists to exercise extreme caution. The advisory includes a clear directive: “Turn around, don’t drown,” when encountering flooded roads. Data from previous storm events show that most fatalities linked to flooding occur when drivers attempt to cross water-covered roads. Even shallow, fast-moving water can sweep away vehicles, posing a significant threat to both occupants and first responders.
