Tropical Storm Arthur has weakened, yet its remnants continue to pose a significant threat to the southeastern United States. Forecasters are warning of several days of heavy rainfall, with some isolated areas potentially receiving up to 20 inches of rain. These conditions are expected to trigger life-threatening floods across the region. In response, coastal communities have taken preventative measures by clearing drains and distributing sandbags. The danger of the rising floodwaters was underscored by a reported drowning incident near Houston. Authorities remain on high alert as the system moves inland.
