Tropical Storm Arthur has been wreaking havoc along the Gulf Coast, bringing with it life-threatening flooding and dangerous conditions. As the storm continues its path, communities in Texas, Louisiana, and Alabama are bracing for the worst.
The storm, which has maximum sustained winds of 40 mph, is expected to bring widespread rainfall totals of 5 to 10 inches, with some areas potentially seeing up to 20 inches. This relentless downpour is causing catastrophic flash flooding, with many areas already experiencing dangerous conditions.
The Storm’s Path and Intensity
As of the latest advisory, Tropical Storm Arthur’s center has re-formed near Galveston, Texas, and is moving northeast at 8 mph. The storm’s wind field stretches outward up to 175 miles, primarily to the southeast of the center over open water. Despite a slight drop in wind intensity, the storm’s massive tropical moisture shield continues to act as an atmospheric pump, bringing heavy rainfall to the region.
The National Hurricane Center has discontinued the Tropical Storm Warning west of High Island, Texas, but the warning remains in effect from High Island eastward to Morgan City, Louisiana. The storm is expected to track across the Southeast before approaching the Carolinas by Friday evening. As it moves offshore, it may pass over the warmer waters of the Gulf Stream, potentially developing into a new area of low pressure.
Impact on Communities
In Texas, officials have reported significant beach erosion and damage, creating hazardous conditions for beachgoers. Dangerous rip currents are also affecting the coast, with storm surge levels reaching up to 3 feet in some areas. Rising water levels are expected to worsen beach conditions and contribute to additional flash flooding across the region.
The devastating human and emotional toll of Tropical Storm Arthur’s relentless moisture shield became painfully clear in southern Mississippi, where a local resident lost her home, workshop, and family animals to a sudden, catastrophic flash flood. Heartbreaking video footage captured by Kristina Malott highlights the severe impact of the storm on communities.
Confusion Over Landfall
As Tropical Storm Arthur grinds its way over Texas, there has been some confusion over whether the storm officially made landfall. The National Hurricane Center’s coordinates place Arthur’s center over the open waters of the Gulf of America at one checkpoint and firmly over solid Texas dirt just a few hours later. This geographical zig-zag is due to the Texas coastline’s dramatic curve and heavy fragmentation by barrier islands, bays, and protruding marshes.
For a system to officially make landfall, its center of circulation must decisively cross from the ocean onto a major landmass. Arthur isn’t doing that; it is essentially “scraping” the shoreline. The center is straddling the literal surf, occasionally cutting across small barrier islands or inland bays like Matagorda Bay before clipping the next piece of coastline.
The storm has been downgraded to a low pressure area along the upper Texas coast, but forecasters expect its remnants to bring life-threatening flooding and days of heavy rains to parts of the southeastern United States. All coastal watches and warnings were discontinued Wednesday night, but flooding is likely through Friday over parts of Texas, Louisiana, Mississippi, Alabama, Georgia, and the Florida Panhandle.
In Louisiana and Mississippi, some communities have set up locations for residents to collect sandbags and cleared debris from drainage systems. New Orleans Mayor Helena Moreno said police were preparing boats and setting up barricades in known flood areas. Collection points for residents to fill sandbags also sprung up around the state.
Officials in Picayune, Mississippi, declared a state of emergency Tuesday after downpours brought nearly 7 inches of rain in six hours. On Wednesday, city officials gave out thousands of sandbags and put emergency responders on standby.
