000 AXPZ20 KNHC 271500 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1500 UTC Mon Jul 27 2020 Tropical Weather Discussion for the eastern Pacific Ocean from the Equator to 32N, east of 140W. The following information is based on satellite imagery, weather observations, radar, and meteorological analysis. Based on 1200 UTC surface analysis and satellite imagery through 1430 UTC. ...TROPICAL WAVES... A tropical wave axis is along 90W north of 03N into Guatemala, moving west at 10 kt. Scattered moderate convection is noted from 08N to 13N between 86W and 92W. A tropical wave axis is along 110W, from 04N to 17N. It is moving west at 10 kt. Convection previously associated with this wave has diminished. A tropical wave extends along 139W from 02N to 17N, moving west at 10 kt. Scattered moderate convection is noted from 08N to 13N between 130W and 140W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough axis extends from 08N78W to 13N110W to 10N131W. The intertropical convergence zone axis extends from 13N130W to beyond 06N140W. Scattered moderate to strong convection is noted from 09N to 15N between 97W and 102W. Scattered moderate convection is observed from 07N to 12N between 110W and 121W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... High pressure west of Baja California will support generally fresh NW winds north of Cabo San Lazaro through Wed night. A deep layer trough moving into the southwest US will allow pressure to lower north of the region Tue. This pattern will support moderate to fresh winds over the northern Gulf of California Tue and Wed. Farther south, light breezes and southerly swell will persist through the period. The monsoon trough will lift northward to off the coast of southern Mexico by Tue. This will support increased showers and thunderstorms, mainly at night. Looking ahead, pulses of fresh to locally strong gap winds are possible in the Gulf of Tehuantepec region Fri through Sun. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR.. The monsoon trough is lifting northward to a position parallel to the coast of Central America by Tue. This pattern will maintain scattered thunderstorms and gentle to moderate southerly winds. Looking ahead, pulses of fresh offshore winds are likely in the Papagayo region Tue night through Fri night, and some locally strong winds cant be ruled out Thu night. REMAINDER OF THE AREA... A ridge of high pressure extends over the waters north of 20N. The pressure gradient between the ridge and the monsoon trough/ITCZ is supporting moderate NE trade winds north of the monsoon trough west of 120W with seas in the 5 to 7 ft range. Meanwhile, cross-equatorial southerly swell E of 115W is subsiding with seas expected to be 7 ft by late today. $$ KONARIK
