000 AXPZ20 KNHC 212205 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 2118 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 1800 UTC surface analysis and satellite imagery through 2115 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 12N E of 92W. A tropical wave extends from 03N to 17N with axis near 106W, moving westward at about 12 kt. Scattered moderate to isolated strong convection is from 07N to 14N between 100W 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 03N to 16N with axis near 114W, moving westward at 10-15 kt. Scattered moderate isolated to strong convection is from 06N to 13N between 110W and 116W. A tropical wave extends from 05N to 17N with axis near 136W, moving westward at about 15 kt. Scattered moderate isolated strong convection is from 08N to 15N between 131W and 140W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 10N86W to 10N110W to 11N130W to 10N140W. Scattered moderate isolated strong convection is from 04N to 12N E of 92W, and from 07N to 14N between 100W and 116W. Scattered moderate convection is from 07N to 15N between 120W and 130W, and from 08N to 15N W of 131W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... The pressure gradient between a surface ridge extending to the offshore waters of Baja California peninsula and elongated low pressure over the Gulf of California will support the continuation of moderate to locally fresh NW winds off the Baja peninsula through Wed morning. The ridge will weaken and shrink to the west for the rest of the week, which will allow for light to gentle winds to dominate these waters through Fri. Moderate to fresh SE to S winds are expected in the Gulf of California Fri and Fri night. Moderate E to SE winds are expected over the offshore waters from Jalisco to Oaxaca diminishing to light winds on Mon. These winds will increase to fresh speeds by Thu as an area of low pressure moves across the area. 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 through the end 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
