A line of showers and thunderstorms associated with a cold front swept through the Lower Texas Coast and over Gulf waters out to 60 nm. A peak gust of 40 knots was recorded at the Rincon del San Jose, TX (RSJT2) Texas Coastal Ocean Observing Network (TCOON) site. With the recorded gust of 40 knots at RSJT2, which is within 1 mile of Gulf Waters,  and Buoy 42020, it is reasonable to expect the nearby Gulf Waters out to 20 NM between Port Mansfield and Baffin Bay also experienced similar gusts.
