Showers and storms during the evening commute

For the next 3 days, we’ll track for the chance for rain with a break, hopefully, by mid-week.

Rain chances drop off by mid week

Flood Watch: San Antonio and Austin areas:

Flood watch in effect until 9 AM Monday. Locally heavy rainfall could trigger flash flooding across portions of south-central Texas. A weak upper-level system combined with above-normal moisture may lead to heavy localized rainfall and rapid runoff.

Rainfall Totals: Most areas can expect 1–2 inches, but isolated storms could reach 3 inches in areas with saturated soils, particularly Kerr County, which has already been hit hard.

Flood Watch Until 9 AM across South- Central Texas

Tracking the tropics:

A 20% chance of cyclone formation looms. We’re monitoring a trough of low pressure near the southeastern coast, expected to move westward across Florida into the northeastern Gulf by Tuesday. This could bring heavy flooding to parts of Florida and the north-central Gulf Coast next week.
