Residents in the affected areas should prepare for heavy rainfall, localized flooding, and gusty winds. Flood waters could inundate streets, parking lots, and underpasses, potentially leading to evacuations and rescues. Coastal areas near Port Arthur and the Louisiana border may experience storm surges of 2-4 feet above ground. The NWS has emphasized the importance of staying alert as conditions could change rapidly, especially if the system strengthens into a tropical cyclone.
