FORECAST
GUADALUPE RIVER
While the river is receding, we are still seeing very high streamflow along the river - upstream AND downstream from Canyon Lake. Please use caution if you are by the Guadalupe today.
Streamflow along the Guadalupe River is very high in places (9:30 PM update) (Copyright 2025 by KSAT - All rights reserved.)
AREA LAKES
We are seeing a rise in local reservoirs, even if it’s a small one. Canyon Lake and Lake Travis are responding most to the rainfall -- up 10 to 20 feet since July 4. Medina Lake has also risen, but is still less than 5% full.
MONDAY
The same upper-level, rainmaking energy that brought deadly flooding July 4th will continue to spin above Central Texas and the Texas Hill Country Sunday.
The coverage of rain may not be as extensive tomorrow (40%), but flash flooding could still happen quickly. Areas of 2″-4″ and locally higher amounts are most likely along and west of Hwy 281 including the Hill Country.
Marginal risk of isolated flooding Monday (Copyright 2025 by KSAT - All rights reserved.)
WEEK AHEAD
We’ll keep rain chances in the forecast through Wednesday, before drying out.
