Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1005 UTC Wed Apr 14 2021

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
0800 UTC.

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

A surface trough extends from 10N74W to 07N77W to 05.5N90W. The 
ITCZ continues from 05.5N90W to 05N117W to beyond 03.5N140W. 
Scattered moderate to strong convection is noted from 05N to 10N
between 78W and 97W. Scattered moderate isolated strong convection
is noted from 03N to 08.5N between 105W and 135W. Scattered
moderate convection is noted from 04N to 08N west of 138W, and
from 17N to 23N between 133W and 140W. 

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A ridge of high pressure extends across the waters west of Baja 
California to near the Revillagigedo Islands. The pressure 
gradient between the ridge and a trough over the Gulf of 
California is supporting moderate northerly winds west of the 
Baja California peninsula. Gentle to moderate northwest to 
west winds prevail elsewhere across the open offshore waters
south of Baja. Overnight scatterometer data showed fresh west to
southwest gap winds across north portions of the Gulf of
California, while light to gentle southerly winds prevailed 
across the remainder of the Gulf. Seas are in the 5-8 ft range 
west of Baja California Norte, 5-7 ft off Baja California Sur, 
4-6 ft over the remainder of the open waters off Mexico, and 3-4
ft over the northern Gulf of California. 

Moderate NW winds will prevail west of Baja California Norte 
through the week, becoming fresh near the coast each late
afternoon, as the ridge persists. NW swell off Baja California 
Norte has peaked on Tue and will slowly diminish to 5-6 ft by Thu
night. Gentle to moderate winds are expected elsewhere through
late Thu. Winds will increase slightly Fri and Sat as the high
pressure shifts southward to near 31N.

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

Light to gentle winds prevail across the forecast area, except
for fresh offshore gaps winds across the Papagayo region. Seas
are in the 4-6 ft range. Little change in wind conditions are 
expected through through Fri. Moderate sized SW swell moving into
the regional waters will dominate the offshore waters through 
Fri.

REMAINDER OF THE AREA...

High pressure across the NE Pacific extends southward along 135W
into the northern waters and then southeastward to near the
Revillagigedo Islands. The pressure gradient between this area 
of high pressure and lower pressure in the vicinity of the ITCZ 
is supporting moderate winds north of the ITCZ to 20N and west 
of 118W. Gentle to moderate winds prevail elsewhere. Seas are in 
the 7-9 ft range over the waters N of 20N between 118W and 130W,
and 7-8 ft elsewhere N of 20N. Seas in the 6-7 ft range prevail 
across the tradewind belt south of 15N. No significant change is
expected through early Thu. High pressure will sink southward to
along 31N late Thu through Fri. This will tighten the pressure 
gradient and freshen winds north of the ITCZ Fri into the 
weekend. Northerly swell will gradually subside across the 
waters from 15N and 30N between 117W and 130W through late Thu.
