Weak surface ridging extending across the offshore waters from the northwest is supporting mainly light to gentle winds. Moderate northerly winds are likely occurring along the Baja California Sur coastline. Seas are 4 to 6 ft in mainly long- period SW swell, mixed with NW swell offshore Baja California. In the Gulf of California, seas are 3 ft or less north of the entrance. Numerous moderate to strong thunderstorms has moved off the Oaxaca, Guerrero and Michoacan offshores from 14N to 18N between 96W and 104W. For the forecast, the pressure gradient will tighten slightly offshore Baja California by tonight. This will lead to winds increasing to moderate to fresh just offshore Baja California through early next week. Mainly gentle variable winds will prevail elsewhere, except for the Gulf of California where moderate to locally fresh SE winds will occur Sat into Sun. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Light to gentle variable winds are north of the monsoon trough, with seas of 5 to 6 ft in SW swell.

Showers and isolated thunderstorms are noted in the Gulf of Panama and across the offshores of Costa Rica, Panama, and Colombia. For the forecast, mainly gentle onshore winds will prevail north of the monsoon trough with gentle to moderate southerly winds south of the monsoon trough. Winds are expected to pulse to fresh speeds offshore southern Colombia and Ecuador early Sat through Sat evening. Southerly swell with moderate seas will propagate across the Ecuador, The Galapagos, and Colombia offshore waters through the weekend. REMAINDER OF THE AREA... High pressure centered well north of the area continues to dominate the weather pattern. Across the waters north of the monsoon trough and west of 125W, moderate NE winds prevail with seas of 5 to 7 ft. Gentle winds and 5 to 6 ft seas are elsewhere north of the monsoon trough. Gentle to moderate southerly winds and seas of 5 to 8 ft are south of the monsoon trough in SW swell, highest near and just north of the Equator. For the forecast, surface ridging will continue to dominate the forecast region north of the monsoon trough through the weekend and into early next week. Seas around 8 ft from the Equator to 10N will subside early this morning. A new set of SW swell may breach 03.4S and west of 100W Mon night. Otherwise, mainly 4 to 7 ft seas will prevail into early next week. $$ AReinhart
