Overview
- The National Hurricane Center gave the coastal low near the Texas–Mexico border about a 60% chance of brief tropical development on Tuesday.
- More than 17 million people are under flood watches from Texas to Mississippi because repeated tropical moisture will produce intense downpours and flash flooding.
- Southeast Texas, including the Houston area, faces another 4 to 6 inches of rain through Thursday with pockets of much higher totals where storms train over the same locations.
- The Storm Prediction Center warned of a major severe outbreak on Wednesday across portions of the Midwest and Ohio Valley with a moderate risk for central Illinois and northern Indiana and tens of millions at risk for tornadoes, damaging winds, and large hail.
- Local impacts already reported include uprooted trees and power outages in the Chicago area and a confirmed fatality after a vehicle was swept away in Bandera County, Texas, while forecasters stress small shifts in the low’s track will rapidly change where the worst flooding occurs.
