NWS National Hurricane Center Miami FL
1400 UTC Sat Apr 25 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 1200 UTC surface analysis and satellite imagery through
1500 UTC.

...SPECIAL FEATURES...

Recently developed Tropical Depression One-E is centered near 
14.0N 116.0W at 25/1500 UTC moving NW at 6 kt. Estimated minimum 
central pressure is 1006 mb. Maximum sustained wind speed is 30 
kt with gusts to 40 kt. Scattered moderate to strong convection
is within 90 NM S semicircle. Scattered moderate isolated strong
convection is noted elsewhere within 120 nm S and 30 nm N
semicircles. The depression is forecast to continue on a NW 
track the next day or so with winds to 30 kt. On Sunday, an 
increase in vertical wind shear and lower SST's is expected to 
lead to the weakening of the depression. See latest NHC 
forecast/advisory under AWIPS/WMO headers MIATCMEP1/WTPZ21 KNHC 
for more details.

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

A surface trough extends from 09N78W to 06N88W to 10N105W. The 
ITCZ extends from 08N119W to beyond 05N140W. Scattered moderate 
isolated strong convection is noted from 01N to 10N E of 107W.
Scattered moderate convection was noted within 60 NM N of the
ITCZ W of 120W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Light to gentle winds prevail over the forecast waters. Seas are
6-8 ft west of Baja California Norte in NW swell. Seas in the 
4-6 ft range elsewhere, except 2 ft or less over the Gulf of 
California. 

Weak surface troughing will prevail over the Baja California 
region through Mon. High pressure will start to build into the 
region from the west by the middle of next week. Seas west of 
Baja California Norte will remain in the 6-8 ft range. A pulse 
of fresh to strong northerly winds are likely in the Gulf of 
Tehuantepec Sun night into Monday morning. Fairly tranquil 
marine conditions will prevail elsewhere through the middle of 
next week.

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

A weak pressure pattern is resulting in mostly light to gentle
winds across the forecast waters. Seas are mainly 4 to 5 ft in a
mix of long period southerly and NW swell.

Fairly tranquil marine conditions are expected across most of 
the forecast area through Wed, except for the Papagayo region, 
where fresh to occasionally strong gap winds are possible.

REMAINDER OF THE AREA...

Please see special features above for more on recently developed
TD One-E.

High pressure prevails north of the area. Outside of TD One-E, 
gentle to moderate winds prevail across nearly all the entire 
discussion area. Seas are in the 5-8 ft range.

Gentle to moderate winds will prevail over this area through the
beginning of next week. High pressure will start to build the 
beginning of next week which will help to freshen trade winds by 
mid-week. Long-period NW swell is expected to maintain combined 
seas of 6 to 7 ft west of 120W this weekend. S swell will likely 
produce combined seas to 7-8 ft in equatorial waters west of 
100W through early Sun.
