HOUSTON, Texas — If you have Memorial Day weekend plans anywhere in the South, it is time to pay close attention to the forecast.
A multi-day storm system is targeting Texas and surrounding states with days of heavy rain and thunderstorms — and forecasters say the flooding risk is serious and growing.
The threat is not a single storm passing through. It is a slow-moving, multi-day event fueled by warm, moist air pushing in from the Gulf of America. That air is colliding with stalled weather systems in the upper atmosphere, creating the conditions for repeated, intense thunderstorms over the same areas.
That repetition is what makes this dangerous.
Tuesday: Houston, Dallas and Austin Are in the Bullseye
The first wave of storms hits central Texas on Tuesday.
Houston, Dallas, and Austin are all under a level 2 out of 4 flash flood risk. That means forecasters expect heavy rain to fall fast — up to 1 to 3 inches in a short period — with serious potential for street flooding, rising creeks, and dangerous road conditions.
If you live in or around these cities, Tuesday is not a day to take weather alerts lightly.
Wednesday and Thursday: The Threat Spreads
The storm system does not stop at Texas.
By Wednesday, the focus shifts to southwest Texas, with San Angelo directly in the line of fire.
On Thursday, the threat expands again — central Texas, Oklahoma, and all of Arkansas move into the danger zone. Louisiana, Arkansas, and Mississippi are also being flagged for flash flood risk through most of the week, sitting at a level 1 out of 4.
This is a wide, multi-state event. Millions of people across the South are in the path of this system.
Why the Flooding Could Be Worse Than Usual
Here is the detail that has forecasters most concerned.
Large parts of Texas and the surrounding region have been dealing with severe to extreme drought conditions. When rain falls on dry, hardened ground, it cannot soak in. Instead, it runs off — fast — straight into streets, low-lying areas, and waterways.
That means even a moderate amount of rain can produce flooding that surprises people who are not prepared.
Memorial Day Weekend: Up to 8 Inches Possible
The system is expected to drag into the weekend, right through Memorial Day.
By Sunday and Monday, rainfall totals across the hardest-hit areas could climb to 5 to 8 inches. That is enough to flood roads, overwhelm drainage systems, and cancel or seriously disrupt outdoor plans for millions of families across the South.
If you are planning to travel, camp, or gather outdoors this Memorial Day weekend anywhere in Texas, Arkansas, Louisiana, Oklahoma, or Mississippi — watch the forecast closely and have a backup plan ready.
Do not wait until the water is rising to make a decision.
