000 AXPZ20 KNHC 271643 AAA TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1605 UTC Wed Jul 27 2022 Tropical Weather Discussion for the eastern Pacific Ocean from 03.4S to 30N, east of 120W including the Gulf of California, and from the Equator to 30N, between 120W and 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. ...SPECIAL FEATURES... Tropical Storm Frank is centered near 12.4N 105.9W at 1500 UTC moving WNW at 9 kt. Estimated minimum central pressure is 1004 mb. Maximum sustained wind speed remain 35 kt with gusts to 45 kt. Scattered to locally numerous moderate to strong convection is noted from 09N TO 14N BETWEEN 105W AND 111W. Scattered moderate isolated strong convection is noted elsewhere from 06N to 15N between 103W and 110W. Seas are peaking near 12 ft, within 45 nm across the N semicircle. Frank is expected to continue on a W to WNW track at near 10 kt during the next few days, while slowly intensifying, and is expected to reach hurricane intensity Fri evening. Newly formed Tropical Depression Eight-E is located near 16.3N 114.8W 1007 mb at 1500 UTC, moving W at 6 kt. Maximum sustained winds are 30 kt and confined to a small area across the N semicircle, where seas are to 10 ft. This small system has been meandering about in this general area for a few days and is expected to move slowly WSW to SW over the next few days and strengthen modestly to a tropical storm. T.S. Frank will move to the NE of the depression in a few days, and interaction between these two systems is possible. This system is expected to be near 14.3N 119.5W by Sat morning as a small tropical storm.

The axis of a tropical wave is near 90W north of 03N, moving westward 10 to 15 kt. Nearby convection is described below. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 10N74W to 08.5N86W to 12N100W, then resumes W of T.D. Eight near 14N117W to 12N128W. Scattered moderate isolated strong convection is noted from 04N to 12.5N between 78W and 91W, from 07N to 16N between 98W and 103W, and from 08N to 12.5N between 120W and 140W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Please see above for more on Tropical Storm Frank. Fresh to strong winds, and seas 6 to 9 ft are noted over the forecast waters off SW Mexico to to the north and northeast of T.S. Frank. Light to gentle winds prevail elsewhere, except reaching moderate speeds off Baja California Norte. Seas are in the 4-6 ft range elsewhere over the open waters off Mexico, with seas in the 2-3 ft range over the Gulf of California. For the forecast, T.S. Frank is expected to continue on a W to WNW track around 10 kt during the next few days, while slowly intensifying. The system will spread fresh to strong easterly winds and seas to around 8 ft across the outer offshore waters of southwest Mexico through Fri before shifting well offshore. Associated swell will continue to spread northward across the waters W of Cabo Corrientes Fri evening and then offshore of Baja Sur Sat, with seas building 8 to 15 ft well offshore. Elsewhere, gentle to moderate NW winds across the waters off Baja California Norte will diminish Fri. Gentle to moderate winds will generally prevail across northern and central portions of the Gulf of California today. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Moderate to fresh offshore winds prevail over and downwind of the Gulf of Papagayo. Gentle to moderate winds are elsewhere north of the monsoon trough, which is along about 10N. Gentle to locally moderate S to SW winds are south of the monsoon trough. Seas are 4 to 6 ft in southerly swell across most of the area. For the forecast, gentle to moderate winds will prevail across the region into the weekend, with slight to moderate seas in south to southwest swell. Winds will pulse fresh to strong at night downwind of the Papagayo region over the weekend. REMAINDER OF THE AREA... See the Special Features section for more information on Tropical Storm Frank. Outside of T.S. Frank, a broad ridge prevails across the waters west of 120W. Winds over the discussion waters are mainly moderate or weaker, with peak wind and seas between 11N and 19N and W of 135W, where seas are to 7 ft. otherwise, seas are generally 4 to 6 ft across the open Pacific. T.D. Eight-E will move generally SW over the next few days and remain to the W and SW of Frank. However, some interaction may occur with these two systems as Frank passes to the NE of Eight-E late Sat and Sun. For the forecast, mainly moderate or weaker winds are expected across the area for the next few days. Expect winds and seas to increase east of 125W as Tropical Storm Frank intensifies while moving westward. $$ Stripling
