000 AXPZ20 KNHC 220903 CCA TWDEP Tropical Weather Discussion...Corrected NWS National Hurricane Center Miami FL 0405 UTC Mon Jun 22 2020 Corrected Remainder of the Area section 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 0000 UTC surface analysis and satellite imagery through 0230 UTC. ...SPECIAL FEATURES... A tropical wave with axis along 107W from 03N to 17N is moving westward at 10-15 kt. This wave is part of a broad area of low pressure that is located several hundred miles south of Manzanillo, Mexico. Latest satellite imagery shows scattered moderate to isolated strong convection from 11N to 14N within 180 nm west of the wave. Scattered moderate convection is within 180 nm west of the wave from 08N to 10N and within 120 nm east of the wave from 10N to 13N. This area of broad low pressure has a medium chance of becoming a tropical cyclone during the next 48 hours. Please refer to the latest NHC Tropical Weather Outlook at www.hurricanes.gov for more details. ...TROPICAL WAVES... A tropical wave with axis along 89W north of 03N is moving westward at 10-15 kt. This wave is embedded within a very moist and unstable atmospheric environment. Scattered moderate to isolated strong convection is seen within 180 nm east of the wave axis from 04N to 06N and within 180 nm west of the wave axis from 05N to 09N. A tropical wave with axis along 115W is moving westward at 10-15 kt. This wave is passing through the southern periphery of a mid to upper anticyclone located near 21N116W. Scattered moderate to isolated strong convection is within 180 nm east of the wave from 08N to 10N and within 120 nm west of the wave from 08N-10N. A tropical wave with axis along 136W from 04N to 17N is moving westward at about 15 kt. Scattered moderate to isolated strong convection is seen from 09N to 13N between 134W and 137W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough axis extends from northern Colombia westward to 10N86W to 10N100W to 10N110W to 11N120W to a 1010 mb low near 12N128W and to beyond the area at 10N140W. Aside from convection described above with the tropical waves, scattered moderate isolated strong convection is within 30 nm of the trough east of 87W. Scattered moderate convection is within 120 nm south of the trough between 127W-130W and within 60 nm south of the trough west of 137W. 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 northwest 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 exist over these waters through Fri. Moderate to fresh southeast to south winds are expected in the Gulf of California Fri and Fri night. Light to gentle over the offshore waters from Jalisco to Oaxaca will increase to fresh speeds by Thu as a forecast area of disturbed weather passes to 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 week. REMAINDER OF THE AREA...Corrected The pressure gradient between a surface ridge north of 15N and lower pressure associated with the monsoon trough and a pair of tropical waves supports fresh to locally strong winds from 11N to 19N and west of about 125W. Wave heights in this region are in the 6-8 ft range. A 1010 mb low near 12N128W is producing scattered moderate convection along and south of the monsoon trough as described above. Last visible satellite imagery shows broad cyclonic turning of low and mid-level clouds over this general area. Environmental conditions are expected to be conducive for some gradual development during the next few days while it tracks generally westward according to the latest Tropical Weather Outlook. Long-period southwesterly swell dominates the waters roughly south of 10N and between 100W-116W, resulting in wave heights of 6-8 ft. These wave heights are forecast to build and gradually shift westward through the middle of the week as the Special Features broad area of low pressure continues to move westward while becoming better organized. $$ Aguirre
