In the later afternoon and overnight hours, there may be a spotty shower. Chance around San Antonio is only 20%, but a little higher closer to the coast because of Tropical Storm Bertha.

T.S. BERTHA

Tropical Storm Bertha is a weak system (Copyright 2026 by KSAT - All rights reserved.)

Tropical Storm Bertha is weakening as it nears the Texas Coast today. Still, it is expected to bring some showers and storms to areas along coastal Texas from Galveston to Corpus, and even near the Rio Grande Valley.

The system will continue to weaken and dissipate as it tracks west toward Texas, causing very little wind and surge impact to the coastal plains on Thursday before disappearing by Friday morning.

Bertha poses no significant threats to travel and will be gone by the weekend. If you have beach plans, keep them.

NUECES & FRIO RIVERS

It is taking a long time for the nearly 500 billion gallons of water that fell last week to drain into Choke Canyon and Lake Corpus Christi along the Nueces and Frio Rivers. Areas of Cotulla and Tilden along the rivers are still flooded. Cotulla, specifically, can expect the Nueces to remain at major flood stage through the weekend.
