The following information is based on satellite imagery, weather observations, radar, and meteorological analysis. Based on 0000 UTC surface analysis and satellite imagery through 0200 UTC. ...TROPICAL WAVES... A tropical wave axis is along 86W, north of 01N into Central America, moving west at 15 kt. Scattered moderate to strong convection is noted from 06N to 13N between 80W and 89W. A tropical wave axis is along 125W south of 18N, moving west at 15 kt. Isolated convection noted within 60 nm of the wave axis. A tropical wave axis is along 134W south of 18N, moving west at 15 kt. Isolated convection noted within 90 nm of the wave axis. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough axis extends westward from Panama near 08N78W to 10N85W to 11N104W. The ITCZ continues from 11N104W to 10N140W. Scattered moderate isolated strong convection is occurring from 07N to 14N between 93W and 104W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Scatterometer data shows gentle to moderate NW flow west of Baja California, associated with an offshore ridge and a trough along the Gulf of California. Gentle to moderate SE winds are over the Gulf of California. Winds are light to gentle south of southern Mexico, except for moderate to fresh northerly winds in the Tehuantepec region. Fresh NW winds will prevail west of Baja California Norte through Sun. Fresh north winds in the Gulf of Tehuantepec will strengthen this weekend following the passage of a tropical wave. Looking ahead, an area of low pressure is expected to develop from this wave south of Mexico over the weekend. Environmental conditions are expected to be conducive for development, and a tropical depression may form early next week while the system moves generally west-northwestward. This area has a high chance of tropical cyclone formation in 3 to 5 days. Please see the latest eastern North Pacific Tropical Weather Outlook for more information. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR... Showers and thunderstorms continue along an active monsoon trough that extends across the region between 08N-10N. Moderate S to SW winds continue south of the trough, with higher gusts possible in and near stronger convection. Wave heights remain in the 4-6 ft range across the forecast waters. Moderate southerly winds will persist south of the trough for the next several days. Fresh winds will pulse across the Gulf of Papagayo region this weekend following the passage of a tropical wave. Long-period southerly swell will build seas near the Galapagos Islands on Fri. REMAINDER OF THE AREA... A broad ridge is analyzed north of 20N, west of 120W. Moderate trade winds are noted across most of the area. Seas are 5 to 6 ft within this region. Little change in marine conditions is expected over the next several days. Long-period southerly swell will propagate northward into the region late Thu night through the weekend. Combined seas are expected to reach 8-9 ft south of the equator by Fri morning. Please see the latest eastern North Pacific Tropical Weather Outlook for more information about the potential for tropical cyclone formation during the next five days. $$ Mundell
