The following information is based on satellite imagery, weather observations, radar, and meteorological analysis. Based on 1800 UTC surface analysis and satellite imagery through 2000 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from low pres 1010 mb near 08N74W to 05N93W to 07N103W to 03N112W to 01N125W. The ITCZ continues from 01N125W to 00N132W to beyond 01N140W. Scattered moderate and isolated strong convection is observed from 01N to 07N between 84W and 121W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Strong SW winds will affect the Gulf of California N of 30N tonight and more so on Fri night in response to a cold front passing through Fri evening. A High pressure ridge W of Baja California will weaken and shift SE through Sun in response to another cold front approaching from 30N140W. Otherwise, gentle to moderate NW winds are expected west of Baja California, with light to gentle winds prevailing elsewhere. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... A high pres ridge N of the Caribbean will cause moderate to fresh offshore winds to pulse at night across the Papagayo region through Fri night. Winds in this region could be locally strong tonight. Light to gentle winds will prevail elsewhere. Scattered showers and isolated thunderstorms affecting the waters adjacent to Costa Rica and Panama will shift E over the waters adjacent to Colombia by Fri. Boaters navigating the waters in these areas should refer to forecasts and statements issued by your local meteorological services. REMAINDER OF THE AREA... High pres centered near 33N140W will maintain moderate to fresh winds between 05N and 20N W of 125W until Sat, then winds in this region will weaken as the high shifts SE in advance of a cold front entering the NW corner of the discussion area. Gentle to moderate winds are expected elsewhere for the next several days. Wave heights range between 6 and 7 ft between 5N and 20N and W of 120W, and 4 to 6 ft elsewhere. Little change in seas is expected through Sun, then long period NW swell could combine with trade wind waves generated by strengthening high pres to the N to cause seas N of 10N and W of 130W to build to between 8 and 9 ft Mon and Tue. $$ CAM
