Arthur’s remnants – Tropical Storm Arthur has formed and then weakened into a post-tropical low-pressure area, but heavy rainfall continues to threaten life-threatening flash flooding and tornado risk across parts of the U.S. Gulf Coast and the Southeast through June 18, with imp
Tropical Storm Arthur may have dissipated into a post-tropical low-pressure area, but the rain it left behind is still finding new places to fall.
By the morning of Thursday. June 18. the system—now downgraded—had already delivered heavy. flooding rain from Texas to the Florida Panhandle. Even as Arthur’s status changed. the National Hurricane Center said heavy rainfall and the possibility of life-threatening flash flooding remain the primary hazards. Through June 18, parts of the southeastern United States also face a chance of tornadoes.
“Ongoing heavy rainfall could prolong the flood threat into the weekend,” the hurricane center said.
Where Arthur goes next matters less than what the storm has already set in motion. The Weather Prediction Center said Arthur’s remnants are expected to keep moving farther eastward through the Southeast from Thursday. June 18. to the morning of Friday. June 19. The immediate forecast centers on continued downpours that can keep rivers rising and streets draining slowly.
The hurricane center warned that flash flooding and urban flooding are likely in southern Louisiana. southern Mississippi. southern Alabama. southwestern Georgia. and the Florida Panhandle by June 18. For residents in those areas. the warning isn’t just about how hard the rain falls—it’s about how long the ground and drainage systems may struggle.
As the remnants slide east, they are expected to collide with a different kind of weather. By June 19. the hurricane center said Arthur’s remaining circulation is expected to get quickly mixed up with an advancing cold front. WPLG-TV hurricane specialist Michael Lowry said in an email that the remaining circulation is expected to zip eastward through Georgia and the Carolinas and into the western Atlantic.
“Once it emerges off the Carolina coast late Friday, [June 19] into early Saturday, [June 20], it could try to redevelop over the western Atlantic,” Lowry said.
That possibility is being watched closely, even with uncertainty. The hurricane center said there is still a signal in the global models for low-pressure development over the western Atlantic late this week or this weekend as remnant vorticity from Arthur emerges off the Southeast U.S. coast. The hurricane center also cautioned that “the exact nature of this low remains unclear. ” adding that model trends will be monitored to evaluate the potential for tropical cyclone formation.
For now. the broader Atlantic outlook offers little comfort to anyone living under a flood threat. but it does narrow the long-term worry. Lowry said the Atlantic basin looks to settle down for the remaining weeks of June. with no development expected elsewhere at least into the middle to latter part of next week.

So it’s basically still dangerous even though it “weakened”??
I swear they say it’s downgraded and then everything’s still like “life-threatening.” Like which is it lol. Flash flooding + tornado risk across the Gulf sounds like a worst case combo.
Wait so Arthur is gone but the rain keeps falling… from where? I saw Texas mentioned and then Florida Panhandle, and I’m like wouldn’t Florida already be done with it if it moved east? Also do tornadoes come from the cold front or the hurricane remnants? My uncle says it’s all just “weather machines” anyway.
“Weakens to a low-pressure area” sounds like they’re trying to calm people down but I don’t buy it. Louisiana/Mississippi/Alabama/Georgia/Florida Panhandle all in the same threat list… that’s way too many places. If rivers keep rising even after the storm passes then what are we even supposed to do, just watch the streets turn into lakes? Someone said it could last into the weekend and honestly I’m not trusting that at all.
