Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1605 UTC Sun Apr 5 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
1515 UTC.

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

A trough extends from 09N75W TO 05N92W TO 00N109. The ITCZ 
continues from 00N109W TO 06N137W TO beyond 05.5N140W. Scattered
moderate convection is noted from 02.5N to 06N between 82W and 
93W. Scattered moderate isolated strong convection is noted
within 06N137W TO 15N124W TO 11N114W TO 06N137W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A surface ridge extends from 1030 mb high pressure near 47N152W 
SE across 30N145W and then broadly ESE to the Revillagigedo 
Islands. The pressure gradient between this ridge and a surface 
trough over the Gulf of California is supporting moderate N-NW 
winds off the Baja California waters. Light S to SW winds 
persist across most of the Gulf of California, while light to 
gentle NW to W winds prevail across the remaining Mexican waters 
from Cabo Corrientes to the Gulf of Tehuantepec. Seas of 4 to 6 
ft prevail W of the Baja California peninsula. Farther south, 
seas of 3 to 5 ft prevail in a mix of NW and SW swell.

A cold front currently moving into the central California coast will
slowly approach Baja California and the Gulf of California 
through Tue. Fresh to locally strong SW winds will pulse across 
the northern Gulf of California ahead of the front tonight and 
Mon night, while winds across Baja California Norte gradually
shift from northerly and become W to SW tonight through Tue. 
Otherwise generally quiescent conditions will persist across the 
offshore waters of Mexico. 

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

Rather quiet conditions are observed over the Central American 
and equatorial waters, with light to gentle winds and seas in the
3-5 ft range prevailing. A western Caribbean high pressure ridge
will build southward Mon through Wed. The resultant pressure 
gradient will support fresh to strong NE to E gap winds across 
the Gulf of Papagayo region. Long-period SW swell will reach the
waters between Ecuador and the Galapagos Islands this morning  
and the Central American waters by this evening.

REMAINDER OF THE AREA...

A strengthening ridge extends from high pressure of 1030 mb 
centered well northwest of the area near 47N152W southeastward to
30N145W and then underneath the frontal system approaching
California to near the Revillagigedo Islands. The pressure 
gradient between the ridge and lower pressure in the vicinity of 
the ITCZ is supporting gentle to moderate tradewinds between the
ITCZ and 23N and to the W of 122W, where seas of 5-7 ft prevail.

A cold front will sweep ESE across the waters N of 25N today 
through early this week, while the weak ridge will prevail S of 
the front. This setup will support gentle to moderate winds, and 
seas in the 4-7 ft range over the forecast waters N of the ITCZ 
through Tue. Fresh trade winds will return late Tue through mid 
week as high pressure builds in the wake of the front.
