Issued at 636 PM CDT Sun Oct 4 2026

- There is a Marginal Risk of Excessive Rainfall on Monday across the southern Coastal Bend, mainly right along the coast south of Port Aransas.

- A Coastal Flood Advisory is in effect until 7 PM Tuesday.

DISCUSSION

Issued at 130 PM CDT Sun Oct 4 2026

A broad mid level trough across the western gulf combined with a stalled frontal boundary along the TX coast will continue to bring scattered to numerous showers and thunderstorms to the Middle Texas Coastal Waters through mid week. However, rain chances will diminish across S TX tonight through Monday as the stalled front drifts farther out into the gulf and a mid level ridge nudges across S TX. Quiet weather is in store for Monday through Wednesday, then Rain chances return later in the week as a mid level low approaches S TX and pushes the ridge southward.

Minor coastal flooding is expected during times of high tide through Tuesday, possibly into Wednesday. This is due to a moderate to strong northeast flow across the northwest gulf waters. High tides will vary from overnight into morning at Baffin Bay and in the morning to afternoon at Port Oconnor, thus tidal overflow may be somewhat continuous over the next couple of days.

AVIATION

(00Z TAFS) Issued at 636 PM CDT Sun Oct 4 2026

MVFR CIGS continue across eastern TAFS this evening, but have temporarily improved west. Expect all terminals to have predominantly MVFR CIGS through the night, though breaking out to VFR at times is not out of the question. A pocket of drier air sinks south into the area during the day tomorrow and CIGS across all sites should eventually return to VFR by the afternoon. Rain chances are low for all sites and have not included any mention. Pockets of drizzle would be possible though overnight tonight, but coverage is too limited to include in TAFs. CRP has a low chance for a shower being closest to a boundary offshore, but again, chances are very low.

MARINE

Issued at 130 PM CDT Sun Oct 4 2026

Fresh to strong (BF 5-6) northeasterly flow is expected through the next couple of days. A small craft advisory is in effect through mid- day Monday at this time, and may need to be extended a bit longer. By mid week, flow subsides and should be mainly moderate to fresh. Scattered to numerous showers and thunderstorms will continue through the period.

FIRE WEATHER

Issued at 130 PM CDT Sun Oct 4 2026

No significant fire weather concerns are anticipated through the work week. Scattered showers and storms continue today, with lower chances mainly confined to the coast Monday. RH values will remain elevated through the week, above 40% each day.
