Overview
- More than 17 million people are under flood watches from central and southern Texas through Mississippi, with life‑threatening flash flooding already reported in parts of the Gulf Coast.
- The National Hurricane Center is monitoring Invest 90L near the upper Texas coast and gives it about a 60% chance of brief tropical development while stressing that heavy rain and flooding are the primary hazards.
- Forecasts call for repeated, training downpours with rainfall rates of 2 to 5 inches per hour and totals of several inches to locally 8–12 inches through Thursday in vulnerable areas such as the Houston metro.
- A separate midlatitude storm setup is expected to produce a significant severe‑weather outbreak Wednesday into Thursday across the Midwest and Ohio Valley with damaging winds, very large hail and possible long‑lived tornadoes in a level 4/moderate risk area.
- The storm system is already causing rescues, road closures, widespread outages and at least one confirmed flood death in Bandera County, Texas, and officials warn that small shifts in the low’s track will change which communities see the worst impacts.
