000 AXPZ20 KNHC 211608 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1544 UTC Sun Jun 21 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 1530 UTC. ...TROPICAL WAVES... A tropical wave with axis near 87W north of 03N is moving westward at 10-15 kt. This wave is embedded within a very moist and unstable atmospheric environment. Scattered moderate isolated strong convection is from 04N to 13N E of 90W. A tropical wave extends from 04N to 17N with axis near 106W, moving westward at about 12 kt. Scattered moderate to isolated strong convection is from 07N to 15N between 103W and 110W. This area of disturbed weather has the potential for some slow development through the middle part of the upcoming week per the latest Tropical Weather Outlook. A tropical wave extends from 05N to 16N with axis near 113W, moving westward at 10-15 kt. Scattered moderate isolated to strong convection is from 07N to 13N between 110W and 116W. A tropical wave extends from 06N to 16N with axis near 135W, moving westward at about 15 kt. Scattered moderate isolated strong convection is from 08N to 14N W of 130W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 11N86W to 10N110W to 11N130W to 10N140W. Scattered moderate isolated strong convection is from 04N to 13N E of 90W, 05N to 13N between 94W and 103W, 07N to 15N between 103W and 116W, 08N to 15N between 118W and 130W, and from 08N to 14N W of 130W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A surface ridge is building eastward to around 26N120W. The associated pressure gradient supports moderate NW winds west of Baja California. Mainly light to gentle winds and 4-7 ft seas prevail elsewhere. Moderate to fresh northwest winds will continue through early next week over the waters from Baja California Sur to Punta Eugenia. These winds should diminish slightly by mid-week. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Moderate to fresh southwest winds continue south of the monsoon trough along with wave heights in the range of 6-8 ft due to southwesterly cross-equatorial swell. Moderate to fresh northeast to east winds in the Papagayo Region will continue into early part of the upcoming week. REMAINDER OF THE AREA... A ridge extends east-southeastward from a 1024 mb high pressure centered near 32N140W to near 24N120W. The associated pressure gradient is supporting fresh trade winds from 10N to 19N west of 120W. Wave heights are in the 6-7 ft range in this area from mixed swell. A surface trough is analyzed along 121W from 08N to 15N. Scattered showers and isolated thunderstorms are noted within 120 nm east of the trough near the monsoon trough. This trough is part of a broad area of low pressure. It is possible that environmental conditions could allow for some slow development of this area of disturbed weather during the next few days while it moves generally to the west. Mainly moderate northeast winds are near this trough along with wave heights in the range of 5-7 ft. Moderate to fresh trade winds and 5-7 ft wave heights are elsewhere north of the monsoon trough west of 120W. Moderate southerly flow is south of the the monsoon trough axis. Long-period southwesterly swell dominates the waters roughly south of 10N and between 99W and 110W, resulting in wave heights of 6-8 ft. These conditions are expected to change little going into early part of next week as southerly winds south of the monsoon trough increase some. $$ Ramos
