FORECAST\"\"Flood Watches will be in effect for Texas until Friday (Copyright 2026 by KSAT – All rights reserved.)<\/p>\n

FLOOD WATCH<\/p>\n

An upper level low, the remnants of Hurricane Polo, and a slow-moving cool front will bring beneficial rain to Texas, but will come with the risk for pockets of flooding.<\/p>\n

Many Texans, including San Antonio, are under a Flood Watch until Friday. Remember: A \u201cwatch\u201d means the ingredients for flooding are there, and we need to be alert until the Watch is discontinued. If you get a flood \u201cwarning\u201d that is more serious, and means that flooding is happening or will begin soon.<\/p>\n

Here\u2019s what you need to know:<\/p>\n

\"\"Rain chances for San Antonio (Copyright 2026 by KSAT – All rights reserved.)<\/p>\n

WEDNESDAY<\/p>\n

While there could be some storms nearer to the Rio Grande, San Antonio will be mostly quiet — except for the afternoon hours. Tomorrow afternoon, there will be a few spotty storms (40%). Some could be strong, so we\u2019ll monitor carefully.<\/p>\n

THURSDAY & THURSDAY NIGHT<\/p>\n

The front will slowly make its way toward San Antonio on Thursday, with storms almost a sure bet by Thursday afternoon. Heavy rainfall and street flooding is a risk. Abundant moisture and training of storms could create isolated rainfall of 8\u2033+ somewhere across South Central Texas. However, most will see beneficial rain totals in the 1-4\u2033 range.<\/p>\n

If you happen to get a bullseye of 6\u2033+, street and creek flooding is likely. Be careful on the roads Thursday! We\u2019re on standby to see how the rain impacts after-school activities.<\/p>\n

FRIDAY (10\/2) — RAIN LIKELY, BUT NOT AS INTENSE<\/p>\n

The front should slowly move south and east, pushing the threat for the heaviest rainfall south of San Antonio on Friday. However, showers and a storm or two is still possible during the day on Friday<\/p>\n

THIS WEEKEND — LIGHTER RAIN, LOWER CHANCES <\/p>\n

Lighter rainfall is expected over the weekend, before chances come to an end early next week. Temperatures will benefit from the rain and give us a decent cool down. Next week, humidity will drop and it will actually feel like fall!<\/p>\n
