134 AXPZ20 KNHC 070200 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 024 UTC Wed Aug 7 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 0000 UTC surface analysis and satellite imagery through 0140 UTC. ...TROPICAL WAVES... A tropical wave has an axis extending from 05N86W to 16N86W, moving W around 15 kt. This wave is embedded in a large area of scattered moderate and isolated strong convection from 05N to 10N between 80W and 97W. A more concentrated area of numerous moderate and scattered strong convection is located just east of the wave axis along the coast of Costa Rica from 07N to 10N between 82W and 85W. A tropical wave has an axis extending from 04N95W to 17N96W, moving W around 15 kt. This wave is also embedded in the large area of scattered moderate and isolated strong convection from 05N to 10N between 80W and 97W. A tropical wave has an axis extending from 04N110W to 16N110W, moving W at 10 to 15 kt. This wave is situated at the eastern edge of a large area of scattered moderate and isolated strong convection from 08N to 14N between 100W and 110W. A tropical wave has an axis extending from 06N130W to 16N129W, moving W around 15 kt. This wave is embedded in an area of scattered moderate and isolated strong convection within 90 nm either side of the monsoon trough axis between 124W and 135W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 09N75W to 08N80W to 12N129W to 08N140W. Numerous moderate and scattered strong convection is found from 07N to 10N between 82W and 85W. Scattered moderate and isolated strong convection is present elsewhere from 05N to 10N between 80W and 97W. Scattered moderate and isolated strong convection is seen from 08N to 14N between 100W and 110W, from 07N to 11N between 110W and 120W and within 90 nm either side of the monsoon trough axis between 124W and 135W. 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 15N136W. Scattered moderate convection is noted in the N quadrant of the low within 60 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
