Tropical Weather Discussion
NWS National Hurricane Center Miami FL
0250 UTC Wed Feb 19 2020

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.


...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...

A surface trough extends from 01N80W to 04N90W. The ITCZ begins near 04N90W and continues to 05N120W to 06N133W. Scattered moderate convection is from 03N to 09N between 110W and 120W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A high pressure ridge extends SE from the NW Pacific to just SE of the Revillagigedo Islands. This ridge will generally remain in place until a stronger reinforcing ridge builds in through the week, leading to fresh NNW winds and building seas for regional waters N of Jalisco. Locally strong winds are possible off Cabo Corrientes this weekend.

Fresh to strong N gap winds will continue pulsing in the Tehuantepec region through Thu. These winds will increase to gale force by Fri through early Sun morning. Elsewhere S of Jalisco, generally gentle winds will prevail.

OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR...

Fresh to strong NE to E gap winds will prevail across the Papagayo region through the week. These offshore winds will prevail as far N as the Gulf of Fonseca, with seas ranging between 8-10 ft. In the Gulf of Panama and S to the equator, fresh N winds will pulse to strong each night into the weekend. Light winds will prevail elsewhere.

REMAINDER OF THE AREA...

A mid-level low pressure over the western waters and its associated surface trough along 138W from 08N-11N will move W of the area by Wed. The pressure gradient in and near it will result in fresh trades continuing through the week. Seas ranging between 5-7 ft are expected in the area.

A weakening cold front will move into the far NW waters Thu, then gradually move toward 125W to the N of 23N through Fri. Behind the front, expect fresh NW winds. Ahead of the front, trade winds will increase to strong by Fri and Sat. NW swell combined with swell generated from the trades will lead to a broad area of 8 to 12 ft swell N of the ITCZ and W of 125W for the end of the week, into the weekend.
