The remnants of the first named storm of the 2026 Atlantic hurricane season are expected to bring major flooding to the U.S. Gulf Coast as the region already reels from excess rainfall.
The National Hurricane Center issued its final public advisory for Post-Tropical Cyclone Arthur on Wednesday night. Arthur was the first named storm of the 2026 Atlantic hurricane season, which began June 1.
An archive of graphics for the storm compiled by the National Hurricane Center reveals that the system rapidly developed into a tropical storm Wednesday before dissipating Wednesday night. Even as Arthur has reached post-tropical cyclone status, the threat of flash flooding from the storm remains.
“Arthur is expected to produce rainfall totals of 5 to 10 inches, with isolated higher totals near 20 inches, through early Friday from the Mid and Upper Texas coast east-northeast into southern and central portions of Louisiana, Mississippi, and Alabama, along with western portions of Georgia and the Florida Panhandle,” The National Hurricane Center stated in the advisory. “This could generate dangerous to life-threatening flash flooding.”
Mississippi Gov. Tate Reeves warned in an X post published Thursday that multiple cities in his state could see “rare and historic flash flooding.”
“Gulfport and Poplarville could see 8 to 10 inches of rain, with locally higher amounts possible in a short amount of time. Many roads could be flooded, closed, or washed out. Many structures could flood, with water rescues expected. Moderate to major river flooding is also possible. McComb, Hattiesburg, Laurel, Meridian, Magee, and Brookhaven could see 4 to 8 inches of rain, with locally higher amounts possible. Totals as high as 10 to 12 inches in a short amount of time cannot be ruled out,” he wrote.
Reeves added that flash flooding is likely and that many roads could be “flooded, closed, or washed out.”
“Flooding of structures is increasingly likely, and water rescues are possible,” Reeves stated, warning also of “minor to moderate river flooding.”
“Yazoo, Vicksburg, Jackson, Philadelphia, Natchez, and Kosciusko could see 2 to 4 inches of rain, with locally higher amounts possible in a short amount of time. Flash flooding is likely. Some roads may be flooded or closed, the governor continued.
“Some structures could be threatened with inundation,” he added. “The most significant rainfall totals are expected to accumulate between 12 a.m. Thursday and late tonight.”
The Alabama Emergency Management Agency estimated the expected impacts of Arthur in a notice published Thursday.
“Torrential rainfall at rates exceeding 2 inches per hour is likely, especially near and south of I-20. Along the coast and counties near the Florida state line, between 6 and 10 inches are forecast by early Friday, with some spots receiving 10+ inches, resulting in catastrophic flooding. Northward to I-20, between 2 and 6 inches are expected, with some spots potentially receiving 6+ inches by early Friday,” the notice reads.
Texas Gov. Greg Abbott issued a disaster declaration in 101 counties in response to a “severe storms event” that began on Sunday, which included flash flooding, hazardous wind gusts, large hail and tornado threats. The storm led to “widespread and severe property damage, injury, or loss of life.”
