331 AXPZ20 KNHC 131606 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1517 UTC Mon Apr 13 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 1500 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from 11N86W to 08N102W to 04N117W. The ITCZ extends from 04N118W to 02N133W to 03N140W. Scattered moderate to strong convection is noted from 0N TO 10N E of 94W. Scattered moderate convection is S of 03N between 87W and 96W, from 08N to 13N E of 102W, from 01N to 04N between 124W and 127W, and from 07N to 10N between 134W and 140W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... The pressure gradient between low pressure over the SW United States and surface high pressure west of the Baja California peninsula is supporting moderate to locally fresh winds along the Baja offshore waters southward to Manzanillo, Mexico adjacent waters. Latest surface observations and model guidance indicate seas in this region continue to be in the 4-7 ft range. In the Gulf of California, gentle to locally moderate winds prevail with seas in the 2-4 ft range. Light to gentle winds dominate the remainder southern Mexico offshore waters with seas in the 5-6 ft range, mainly in SW swell. With the area of low pressure moving east and the slight weakening of the ridge to the west by Wed, the pressure gradient across the region will relax, and winds will decrease to gentle to moderate speeds west of Baja and in the Gulf of California. These conditions will then continue through Fri while light to gentle winds will dominate elsewhere. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Gentle to moderate gap winds prevails in the Gulf of Papagayo with seas in the 4 to 6 ft range. Light to gentle winds prevail elsewhere. Seas are in the 6-7 ft range between the Galapagos Islands and Ecuador in SW swell. Elsewhere, seas are in the 4-5 ft range. Moist S to SW flow will prevail over the forecast area through the middle of next week. Large scale atmospheric conditions will be favorable for enhanced widespread convection. Conditions will be favorable for locally heavy rainfall to persist over the waters near the equatorial trough axis, and shift eastward into southern Costa Rica, Panama, western Colombia and northwest Ecuador during the next several days. Please refer to forecasts and statements issued by your local meteorological services. Moderate to fresh offshore gap winds will pulse at night across the Gulf of Papagayo region through Fri. With active convection associated with the equatorial trough, latest model guidance forecast fresh to locally strong SW to W winds over Costa Rica and northern Panama offshore waters Tue and Wed. Light to gentle winds will prevail elsewhere along with long period cross-equatorial S-SW swell. REMAINDER OF THE AREA... High pressure prevails across the northern waters. The pressure gradient between this are of high pressure and lower pressure within the equatorial trough is supporting gentle to moderate winds from 05N to 20N west of 110W. Light to gentle winds prevail N of 20N, and gentle to moderate winds prevail S of 05N. Seas are in the 6-8 ft range S of 15N and W of 95W. Seas in the 4-6 ft range prevail elsewhere. The ridge will continue to prevail over the northern waters through the upcoming week with the same general conditions. Widespread active convection occurring S of 10N and E of 120W will continue at least through the middle of the week, as large scale conditions are favorable for deep convection. $$ Ramos
