GMZ400-182115- 355 AM CDT Tue Jun 18 2024 .SYNOPSIS... Potential Tropical Cyclone Number 1 in the southwestern Gulf of Mexico will gradually move west-northwest toward the eastern Mexico coast through Thursday. Deep moisture will be associated with this system that will bring widespread shower and isolated thunderstorm activity. A strengthening gradient between the disturbance and high pressure to the northeast will generate moderate to strong east to southeast winds through mid week, while the prolonged fetch will allow for a significant increase in wave heights and swells, as well as an increased risk for coastal flooding. $$ GMZ430-182115- Sabine Lake- 355 AM CDT Tue Jun 18 2024 ...SMALL CRAFT EXERCISE CAUTION IN EFFECT THROUGH THURSDAY MORNING... .TODAY...East winds 10 to 15 knots with gusts up to 25 knots.
