DISCUSSION

Issued at 1211 AM CDT Fri Oct 9 2026

The forecast has continued to remain on track from the previous few forecasts. We expect drier conditions to continue through the weekend in South Texas outside of isolated seabreeze showers and thunderstorms. That is due to weak mid level ridging and a slightly drier airmass that is parked over the region. We will likely still see some activity over the Texas waters due to Hurricane Isaias as it moves north-northeast away from us. We will see those drier conditions across the region leading to much warmer temperatures across S TX. Some residual energy from Hurricane Simon over in the Pacific will look to creep into the region early next week with South Texas on the right flank of the area of low pressure. Ahead of this onshore flow will return to the region allowing for deep moisture pooling. The presence of these to factors will likely lead to a low chance for unsettled weather in the region Monday. Will continue to monitor this over the next few model runs.

The main concern Hurricane Isaias will bring to South Texas will be an increased risk of coastal flooding, high rip current risk and seas building up to potentially 9-10 feet (confidence is moderate to high in this occurring over the Gulf waters given the higher periods and northeast winds). A Coastal Flood Advisory will remain in effect through Sunday morning. Models remain in agreement that swell periods will increase to 9-10 seconds by this after afternoon/evening along with the increased seas. This will provide sufficient energy to push the water up to the dunes.

AVIATION

(12Z TAFS) Issued at 624 AM CDT Fri Oct 9 2026

Other than some light haze at VCT this morning, VFR conditions are expected for all sites today. MVFR VIS could develop again at VCT tonight, but confidence is not great.

MARINE

Issued at 1228 AM CDT Fri Oct 9 2026 Northeasterly winds around moderate to fresh (BF 4-5) levels continue with periods of fresh and strong levels through the day, especially offshore. Periods are expected to build around 9-10 seconds with seas around 9-10 ft by Friday afternoon/evening. A Small Craft Advisory has been expanded to the nearshore waters and remains in effect through Friday. Winds will subside by Saturday.

FIRE WEATHER
