Remnants of Tropical Storm Arthur Drive Life‑Threatening Flooding Along Central Gulf Coast

Overview

• Heavy bands from the Arthur remnant produced catastrophic rainfall on Thursday with MRMS estimates over 9 inches and multiple mesonet sites recording more than 11 inches in parts of Louisiana and Mississippi.
• Forecasters warned on Friday that renewed rounds of training storms will bring additional flash flooding into southern Mississippi, southern Alabama, southwest Georgia and the Florida Panhandle with common rates of 1–2 inches per hour and isolated 2–4 inches per hour.
• Meteorologists say the extreme rainfall is driven by very high precipitable water values often above 2.2 to 2.6 inches, strong low‑level inflow and mesoscale convective vortices that anchor repeating heavy bands.
• Separate clusters of slow‑moving storms in the southern Plains, including the Texas Panhandle and southwestern Oklahoma, are producing heavy rain and isolated flash flooding while the Upper Midwest is being monitored for an increasing large‑hail and damaging‑wind threat that could prompt watches.
• Local communities face rapid rises on creeks, flooded roads and overwhelmed drainage because soils are saturated; National Weather Service offices and River Forecast Centers urge residents to follow local warnings and avoid driving through flood waters.
