000 AXPZ20 KNHC 142034 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 2205 UTC Wed Jun 14 2023 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 1800 UTC surface analysis and satellite imagery through 2000 UTC. ...TROPICAL WAVES... A Caribbean tropical wave is moving W at 10 kt and is beginning to cross into the far eastern Pacific along 79W. Scattered moderate convection associated with this wave is impacting the Gulf of Panama. A tropical wave is along 91W north of 03N, moving west at 10 kt. Scattered moderate convection is noted from 04N to 12N between 82W and 96W. A tropical wave is along 111W from 02N to 12N, moving west at 5 to 10 kt. Scattered moderate to isolated strong convection is from 05N to 12N between 107W and 117W. A tropical wave is analyzed along 126W from 03N to 12N, moving west at 5 kt. No significant convection is evident in the vicinity of the wave. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 10N85W to 10N108W to 07N134W. The ITCZ continues from 07N134W to beyond 07N140W. Aside from the convection associated with the tropical waves, scattered moderate convection is evident from 07N to 10N between 96W and 105W. Scattered moderate convection has also developed from 07N to 10N between 131W and 134W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Fresh NW winds are occurring W of Baja California due to the pressure gradient between high pressure well W of the area and low pressure centered just N of the Gulf of California. Moderate to fresh winds are also ongoing in the southern Gulf of California. Elsewhere, winds are mainly gentle. Seas are 5 to 7 ft W of Baja California, 2 to 4 ft in the southern Gulf of California, and less than 2 ft in the northern Gulf of California. Elsewhere in the Mexican offshore waters, seas are generally 4 to 6 ft. For the forecast, a trough will deepen slightly over the lower Colorado River Valley and northern Gulf of California through Fri, while a weak ridge persists between Los Cabos and the Revillagigedo Islands. This pattern will support fresh NW winds off Baja California through late Fri, with fresh SW winds pulsing over the northern Gulf of California tonight and Thu night. Gentle winds will persist elsewhere. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Light and variable winds prevail over the offshore forecast waters of Central America and Colombia while moderate SE to S winds are mainly south of 02N, including the waters between Ecuador and the Galapagos Islands. A pulse of moderate to locally fresh gap winds is ongoing in the Papagayo region. Seas are 3 to 5 ft in SW swell across the Central America and Colombia offshore waters and and 6 to 8 ft between the coast of Ecuador and the Galapagos Islands. For the forecast, a weak pressure gradient will remain in place across the region supporting mainly light to gentle variable winds across the Central America offshore waters, except for moderate to fresh NE gap winds in the region of Papagayo into tonight. Moderate, long-period SW swell will persist mainly south of 10N building seas to 8 or 9 ft between Ecuador and the Galapagos Islands into Thu. ...REMAINDER OF THE AREA... Moderate to fresh SW winds are converging into the area where the tropical wave near 110W is interacting with the monsoon trough and surface pressure is lowering. Seas in this area are 6 to 8 ft. Farther south, southerly swell to 8 ft is reaching to the equator. Gentle to moderate SW winds and southerly swell of 5 to 7 ft is evident elsewhere east of 110W. Farther north and west, a ridge extends from high pressure centered northwest of the across the subtropical waters to near Baja California Sur. The pressure gradient between the ridge and lower pressures associated with the monsoon trough/ITCZ is supporting a belt of moderate to locally fresh NE winds from 08N to 20N west of 125W where seas in the 5 to 7 ft range in mixed SE and NW swell. The interaction of the ridge and a trough extending southwest off southern California is supporting moderate NE to E winds north of 20N and west of 130W, with 5 to 7 ft combined seas. Mainly gentle northerly winds are elsewhere north of the ITCZ/monsoon trough while gentle to locally moderate SE winds with seas 5 to 7 ft are south of these boundaries in southerly swell. For the forecast, weak low pressure is expected to develop tonight near 10N110W, not far from Clipperton Island, and this feature may support fresh to locally strong winds, rough seas and thunderstorms within 90 nm of the center through the next couple of days before the low gradually weakens. There is a 20% chance of of tropical cyclone development through 48 hours. See hurricanes.gov for more information. Elsewhere, fresh NW winds and building seas can be expected starting Thu, north of 25N and west of 130W between high pressure northwest of the area and a persistent trough extending southwestward off southern California. Little change in the pattern or impacts is expected through late week, except for slightly higher trade wind flow north of 08N and west of 125W. $$ KONARIK
