Storms bring flash flood threat to Texas Hill Country, Houston sets up a stormy end to the week

Tropical rain will bring flash flooding to the state of Texas:

A Flood Watch is in effect through Friday night. A Flood Watch means all the ingredients are present for flooding. Rainfall totals of 2 to 4 inches are expected, with some spots potentially picking up 5 to 8 inches.

Right now, Southeast Texas is not included in the watch.

Timing:

The heaviest rain in the Hill Country is expected to begin early Thursday morning, with storms slowly moving east.

The rainfall forecast generally lines up with the Flood Watch. It is important to know that in flood threats like this there will be a wide range of rain totals. Any kind of flooding in this area is life threatening.

There will be an isolated thunderstorm in Houston Thursday afternoon, but the more widespread rain doesn’t arrive until Friday afternoon.

Tracking the tropics:

So far this hurricane season we’ve had eight tropical storms. We have not had a hurricane in the Atlantic basin. The latest first hurricane to form was Gustav and Humberto, which formed on September 11th. This means our 2026 hurricane season set a record for the latest hurricane to form.

Rain chances are with us through the weekend so having some alternative plans is a good idea. However, next week, we should dry out and cool off just a touch heading into the first full week of October.
