Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1005 UTC Thu Apr 30 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 0600 UTC surface analysis and satellite imagery through 
0900 UTC.

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

A surface trough extends from 06N78W to 08N88W to 09N108W. The 
ITCZ extends from 05N107W to 04N129W to 04N140W. Scattered 
moderate convection is noted from 04N to 08N between 89W and 
97W, and from 02N to 06N between 125W and 140W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

High pressure centered near 32N133W extends a ridge SE near the 
Revillagigedo Islands offshore of southern Mexico. Scatterometer 
data shows light to gentle winds across most of offshore waters. 
Seas are generally 5-6 ft off Baja California Sur. Satellite 
analysis indicates smoke from agricultural fires has spread into 
the waters S of Cabo Corrientes. Haze and reduced visibilities 
are possible at times in coastal waters. 

The ridge will persist through early next week. Near gale force 
northerly winds are expected in the Tehuantepec region through 
Fri as high pressure builds behind a Gulf of Mexico cold front. 
NW swell will build seas west of Baja California through Sat.

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

Scatterometer data shows gentle to moderate winds across most of 
the offshore waters. Seas are 4 to 6 ft west of Central America.

Fresh gap winds will pulse in the Papagayo region through Mon. 
Smoke from agricultural fires in Central America may cause haze 
and reduced visibility in coastal waters west of Guatemala and 
El Salvador. Elsewhere, relatively tranquil marine conditions 
will persist through early next week.

REMAINDER OF THE AREA...

A ridge extends across the northern waters from high pressure 
centered near 32N133W. Scatterometer data shows mostly gentle to 
moderate trades south of the ridge west of 120W, with slightly 
higher winds noted near a trough that extends from 10N122W to 
02N131W. Seas are generally 6-7 ft within thregion, possibly to 
8 ft near the trough axis. NW swell over the far NW portion is 
producing 8 ft seas that will propagate SE and decay by tonight.

High pressure will persist across the northern waters through 
early next week. NW swell will impact the waters west of Baja 
California tonight and Fri, building seas to 8-9 ft E of 120W by 
Fri morning. Looking ahead, winds and seas may increase west of 
Baja California Norte Sun night through Tue as high pressure 
builds NW of the region.
