The remnants of Tropical Storm Arthur continue to bring heavy rainfall and life-threatening flash flooding to the southern United States, with 10 million people across Texas, Louisiana, Alabama, Mississippi, Georgia, and the Florida Panhandle under flash flood watches. The storm, which weakened below tropical storm strength, has already caused significant damage, including downed trees, knee-deep floodwaters, and destroyed buildings in Louisiana. Preliminary rainfall totals in Louisiana include 29 inches in Cottonport, 22 inches in Plaucheville, and 17 inches in Simmesport, which, if verified, would set a new 24-hour state record for rainfall. Other areas, such as Perkinston and Black Creek, Mississippi, and Village Mills, Texas, have also reported a foot of rain.
Slow-moving storms are expected to produce 2 to 3 inches of rainfall per hour, increasing the risk of flash flooding in cities like Hattiesburg and Biloxi, Mississippi, and Mobile and Dothan, Alabama, where additional rainfall totals through Saturday may reach 4 to 6 inches. The storm is expected to dissipate by June 20, though the National Hurricane Center has given it a 10% chance of regaining strength as it moves into the Atlantic Ocean.
Meanwhile, the storm's remnants have extended coastal hazards to the Carolinas and Virginia, with strong thunderstorms and wind gusts up to 50 mph impacting areas like New Hanover and Brunswick Counties in North Carolina. The National Weather Service issued a beach hazard statement for coastal counties, warning of moderate rip current risks that could sweep swimmers into hazardous areas. The system is expected to completely dissipate by June 20, but its remnants continue to pose risks to coastal communities.
