DISCUSSION

Issued at 151 AM CDT Wed Jun 17 2026

Potential Tropical Cyclone One is forecast to move away from S TX as it moves northeast parallel to the upper Texas coast today. Little to no significant impacts expected for S TX. Rain chances also diminishing across the area as drier air moves into S TX in response to mid level ridging in the wake of the low pressure. Drier conditions expected through Friday with rain chances returning Friday night and into the weekend with the approach of an upper level disturbance.

With an upper level ridge building across the area today, temperatures will be quite a bit warmer with highs in the 90s. Very humid conditions combined with these temperatures will lead to heat indices ranging from 110-114 across the eastern Brush Country, Victoria Crossroads and Coastal Bend this afternoon. Therefore, a Heat Advisory has been issued for this afternoon from 1 pm to 7 pm. Slightly drier conditions expected for the western Brush Country and Rio Grande Plains will lead to heat indices of 105-109 this afternoon. Another hot day expected Thursday with Heat Advisory likely needed. The heat indices could be even higher with an Excessive Heat Warning possibly needed for portions of S TX.

A Moderate Rip Current Risk expected today and tonight due to swell periods around 8 seconds. Minor Coastal Flooding is less likely today as winds shift to the west in the wake of Potential Tropical One, but the seas offshore combined with the swell periods could still lead to minor coastal flooding today with the next high tide. Therefore, will maintain the Coastal Flood Advisory for today.

AVIATION

(12Z TAFS) Issued at 629 AM CDT Wed Jun 17 2026

Currently have a mix of VFR conditions west, IFR at ALI/CRP and LIFR at VCT. Expecting a return to VFR across all terminals by this afternoon as clouds continue to clear from west to east. Light and variable winds this morning should stay light but shift southeast in the afternoon. A few light showers remain possible today affecting eastern terminals but confidence not high enough to include in the TAFs at this time. Overnight conditions tonight expected to be mainly VFR but have included MVFR CIGs for ALI due to potential fog.

MARINE

Issued at 151 AM CDT Wed Jun 17 2026

A fresh to strong (BF 5-6) offshore flow with occasional gusts near gale force and seas 5-7 feet can be expected today as Potential Tropical Cyclone One moves northeast along the upper Texas Coast. Winds are expected to diminish late this afternoon and tonight as the tropical system lifts away from the region. A fresh to occasionally strong (5-6) south to southeast flow is expected to develop by tonight and continue through the period. Very low rain chances expected this afternoon through Friday with low to medium chances returning by the weekend.

FIRE WEATHER

Issued at 151 AM CDT Wed Jun 17 2026

Fire weather concerns will remain low through the period due to elevated relative humidity values and wet fuels. Rain chances are very low today through Friday, with low to medium chances by the weekend.
