1251 AM PDT Mon Aug 17 2026

.SYNOPSIS...The pressure gradient between high pressure over the
Gulf of America and relatively lower pressure south of Mexico
will continue to induce pulses of strong north winds over the
Gulf of Tehuantepec through Wed night, with moderate to fresh
pulses thereafter. Winds will reach reach near gale force at
times early this morning, tonight and Tue night, while resultant
rough seas are also expected. Fresh northwest winds are forecast
