000 AXPZ20 KNHC 062206 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 2021 UTC Tue Aug 6 2019 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 2140 UTC. ...TROPICAL WAVES... A tropical wave has an axis extending from 05N85W to 18N84W, moving W around 15 kt. This wave is embedded in a large area of scattered moderate and isolated strong convection within 160 nm either side of a line from 06N80W to 09N95W. A tropical wave has an axis extending from 05N94W to 18N94W, moving W at 15 to 20 kt. This wave is also embedded in a large area of scattered moderate and isolated strong convection within 160 nm either side of a line from 06N80W to 09N95W. A tropical wave has an axis extending from 03N109W to 16N109W, moving W around 15 kt. This wave is embedded in a large area of scattered moderate and isolated strong convection from 07N to 14N betwen 99W and 110W. A tropical wave has an axis extending from 06N128W to 17N128W, moving W at 10 to 15 kt. This wave has an area of scattered moderate and isolated strong convection associated with it from 12N to 15N betwen 125W and 129W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from low pres 1009 mb near 10N75W to 08N79W to 10N94W to 10N112W to 12N128W to 08N140W. Scattered moderate and isolated strong convection is present within 160 nm either side of a line from 06N80W to 09N95W, from 07N to 14N between 99W and 110W, from 08N to 11N between 116W and 121W and from 12N to 15N between 125W and 129W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A high pres ridge will dominate the waters W of the Baja Peninsula and maintain moderate NW to N winds along the W coast of Baja through the forecast period. The same high pressure ridge will combine with a low pressure trough over the Baja Peninsula to generally maintain light to moderate SE to S winds over the Gulf of California. Several tropical waves will pass over the far southern waters and produce little weather impact other than showers and thunderstorms. Long period SE and SW swell will gradually decay through Thu, and another set will arrive Thu night. However, combined seas will remain less than 8 ft. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Moderate winds over the Gulf of Papagayo could become fresh Sun. Gentle to moderate S to SW winds will prevail south of the monsoon trough through the forecast period. A fresh set of long period SW swell will move into the southern waters later this week. This will cause seas to build to between 6 and 9 ft between the coast of Ecuador and the Galapagos Islands Thu night through Sun night. REMAINDER OF THE AREA... The remnant low of Gil is centered near 15N134W. Scattered moderate convection is noted in the NW quadrant of the low within 90 nm. The latest scatterometry only showed moderate to fresh winds in a small area on the north side of the low. Seas in this area were running 6 to 7 feet. Elsewhere, high pressure centered north of the waters is dominating weather. Gentle to moderate NE winds are generally occurring N of the monsoon trough and W of 120W. S of the monsoon trough winds are generally SE to S. Wind speeds are generally light to moderate W of 100W. Wind speeds E of 100W are moderate to fresh. Mixed SE and SW swell from the Southern Hemisphere continues to arrive in this area. Seas are as high as 8 to 9 feet from 05N to 09N between 94W and 103W. The long period swell from the Southern Hemisphere will decay through Thu, before another set of long period southerly swell propagates into the region beginning on Thu night. $$ CAM
