000 AXPZ20 KNHC 102200 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 2205 UTC Fri Apr 10 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 1800 UTC surface analysis and satellite imagery through 2030 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from 09N75W TO 08.5N82.5W TO 07N103W TO 03N120W. The ITCZ continues from 03N120W to beyond 04N140W. Scattered moderate to strong convection is noted from 02.5N TO 08.5N between 77W AND 97W. Scattered moderate isolates strong convection is noted from 02N TO 09N between 105W AND 132W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Fresh NW winds, associated with a high pressure ridge extending SE into the area, prevail across the waters from Punta Eugenia southward to Cabo Corrientes and the Revillagigedo Islands, where seas remain in the 5-7 ft range. Low pressure along the southern California coast is inducing moderate west to southwesterly winds across far portions of Baja California Norte while gentle to moderate NW to N winds prevail elsewhere west of Baja California Norte. Seas are in the 5-7 ft range over the open waters off Mexico, and 3-5 ft over the southern Gulf of California. Deep layered low pressure persisting along the southern California coast has forced the NE Pacific ridge to build underneath this feature, and southward into the far NW waters through 30N135W, then SE to the waters offshore of Cabo Corrientes. The low pressure will shift slowly SE and inland through tonight, while weakening, and briefly allow the high to build modestly SE and freshen the wind flow offshore of Baja California Sur and Cabo Corrientes through Sat evening. Seas there will build 7-8 ft through Sat evening before slowly subsiding. Otherwise, moderate to fresh NNW winds will prevail through the weekend across the Baja waters, as well as the southern Gulf of California. Moderate to fresh NW to W winds can be expected offshore from Manzanillo to Acapulco. Winds and seas will decrease Sunday through Tue of next week as the high reorganizes farther west of the region. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Moderate offshore gap winds prevail across the Gulf of Papagayo region and the Gulf of Panama this afternoon. Light to gentle onshore winds prevail elsewhere. Seas are generally in the 4-5 ft range. Strong thunderstorms are occurring offshore of western Panama and SE Costa Rica and extend WSW into the deep tropics along 94W. Moist south to southwesterly flow is expected to gradually increase over the forecast waters south and east of the Papagayo region, as large scale atmospheric conditions become favorable for enhanced widespread convection through the middle of next week. Conditions appear favorable for locally heavy rainfall to persist over the waters near the ITCZ and trough, and shift eastward over southern Costa Rica, Panama, western Colombia and northwest Ecuador the next several days. Please refer to forecasts and statements issued by local meteorological services. Otherwise marine winds and seas will remain generally tranquil across the offshore waters through the weekend. New cross equatorial S-SW swell will move into the regional waters beginning Sun. REMAINDER OF THE AREA... The gradient between high pressure over NW waters between 130W and 140W, and lower pressures near the equator is supporting moderate to fresh northeast trades, and 7-9 ft seas, from 06N to 21N between 118W and 138W. Winds across the tradewind belt will start to diminish over the weekend as the high pressure area weakens. Very active convection occurring along and to the north of the equatorial trough and the ITCZ will continue through Sun, as atmospheric conditions become favorable for deep convection across most of the tropical northeast Pacific. $$ Stripling
