Tropical Weather Discussion
NWS National Hurricane Center Miami FL
0405 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 0000 UTC surface analysis and satellite imagery through 
0300 UTC.

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

A surface trough extends from 07N78W to 06N82W to 09N88W to 
08N99W. The ITCZ extends from 05N100W to 04N119W, then continues 
from 05N132W to 05N140W. Scattered moderate convection is noted 
from 05N to 10N between 87W and 98W. Scattered moderate isolated 
strong convection is observed from 02N to 08N between 123W and 
130W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

High pressure centered near 32N134W extends a ridge SE near the 
Revillagigedo Islands and offshore of southern Mexico. Recent 
scatterometer data show light to gentle winds across most of the 
offshore waters. Seas are generally 4-6 ft off Baja California 
Sur. Satellite analysis indicates smoke from agricultural fires 
has spread into the waters south of Cabo Corrientes. Haze and 
reduced visibilities are possible at times in near shore waters. 

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

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

Recent scatterometer data shows fresh winds in the Papagayo 
region. Gentle to moderate winds are found elsewhere across the 
discussion area.

Fresh to occasionally strong gap winds will pulse in the 
Papagayo region through Mon. Smoke from agricultural fires in 
Central America may cause haze and reduced visibility 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 32N134W. Recent scatterometer data shows gentle to 
moderate trades south of the ridge generally west of 120W, with 
fresh winds noted near a trough that extends from 10N122W to 
02N131W. Seas are generally 5-7 ft within these trades, possibly 
to 8 ft near the trough. NW swell over the far NW portion is 
producing 8-9 ft seas that will propagate SE tonight then decay 
on Thu.

High pressure will persist across the northern waters through 
early next week. NW swell will impact the waters west of Baja 
California beginning Thu night, and build seas to 8-9 ft east of 
125W by Fri morning. Looking ahead, winds and seas may increase 
west of Baja California Norte Sun night through Mon night as 
high pressure builds NW of the region.
