OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Moderate to fresh NW winds are occurring offshore Baja California Norte. Moderate to fresh southerly winds are occurring in the central Gulf of California, with fresh to strong in the northern Gulf of California. Seas are 2 to 4 ft, locally to 5 ft, in the Gulf of California. Gentle to moderate winds prevail elsewhere, with seas of 4 to 7 ft in mixed swell, except 6 to 8 ft offshore of Baja California Norte. For the forecast, moderate to fresh SW wind will pulse to strong nightly through the end of the week in the northern Gulf of California as convection over mainland Mexico propagates offshore. A moderate northerly swell will impact the waters offshore of Baja California Norte through the end of the week. An area of low pressure is expected to develop a few hundred miles south of the southwestern coast of Mexico this weekend. Environmental conditions are forecast to be conducive for some gradual development thereafter, and a tropical depression may form early next week while the system moves west- northwestward at 10 to 15 kt, parallel to and offshore the coast of southwestern Mexico. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR... Gentle to moderate south-southwest winds are occurring south of the monsoon trough. To the north of the monsoon trough, gentle winds prevail, with some locally moderate winds near the Papagayo region. Seas are in the 3 to 6 ft range in long period mixed swell. For the forecast, surges of locally fresh winds are likely over the offshore waters north of Costa Rica during the overnight hours tonight through the weekend as convection over Central America propagates offshore. Otherwise, fairly tranquil winds should prevail through the forecast period. A moderate southerly swell may propagate across the waters west of Ecuador during the weekend. REMAINDER OF THE AREA... See the Special Features section above for details on Tropical Storm Hilda and newly upgraded Tropical Storm Jimena. Elsewhere, a surface ridge prevails north of the systems. Moderate to fresh N-NE trades are noted under the ridge and north of the convergence zone, with gentle to moderate flow south of the convergence zone. Seas are 4 to 7 ft in mixed long period swell outside of the systems. For the forecast, winds and seas over some sections of the area, mainly N of 12N and W of 125W, will be impacted by the tropical systems detailed in the Special Features during the next several days, with conditions gradually improving by the end of the week into the start of the upcoming weekend. $$ KONARIK
