Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1005 UTC Fri Apr 8 2022

Tropical Weather Discussion for the eastern Pacific Ocean from
03.4S to 30N, east of 120W including the Gulf of California, and
from the Equator to 30N, between 120W and 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
0830 UTC.

...SPECIAL FEATURES...

High pressure is building across the western Gulf of Mexico in 
the wake of a cold front. The pressure gradient between this 
area of high pressure and the equatorial trough is supporting 
gale- force gap winds over the Gulf of Tehuantepec. The area of 
high pressure will continue over the western Gulf, supporting the
tight gradient through Sat. On Saturday, the area of high 
pressure will start to shift eastward. This will loosen the 
gradient across the Tehuantepec region, and veer winds over the 
western Gulf of Mexico. This will diminish winds below gale force
by Sat evening. Seas will peak near 15 ft tonight into early 
Sat, subsiding below 8 ft by Sun morning. Seas generated from 
this gale- force gap wind event will spread far from the 
Tehuantepec region, with seas greater than 8 ft reaching as far 
west as 105W Saturday.

National Hurricane Center at the website

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

A surface trough extends from the coast of Colombia near 08N78W 
to 06N86W to 07N97W. The ITCZ continues from 07N97W to 08N112W.
It resumes from 07N120W to 06N140W. Scattered moderate isolated 
strong convection is noted from 01N to 09N between 80W and 100W,
and from 05N to 10N between 106W and 120W. Scattered moderate 
convection is noted from 03N to 07N between 130W and 140W. 

OFFSHORE WATERS WITHIN 250 NM OF MEXICO

Please refer to the Special Features for details on the latest
gale- force gap wind event in the Gulf of Tehuantepec.

Aside from the gale- force winds in the Gulf of Tehuantepec,
gentle to moderate winds are noted west of the Baja California
peninsula, with light to gentle winds elsewhere over the open
waters off Mexico. Fresh to locally strong winds prevail over 
the Gulf of California. Seas are in the 6-8 ft range west of the
Baja California peninsula and 4-6 ft over the remainder of the 
open waters off Mexico. Seas of 3-6 ft prevail over the Gulf of 
California. 

For the forecast, the gale- force winds will continue through 
Sat before diminishing. Northerly swell over the waters west of 
the Baja California peninsula will subside today. Another set of 
northerly swell will enter the waters off Baja California Norte 
on Sat. This swell will spread across the waters west of the Baja
California peninsula through the weekend into early next week. 
Fresh to locally strong winds over the Gulf of California will 
diminish today. 

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

Moderate to fresh winds are noted over the Gulf of Papagayo with
gentle to moderate winds over the waters between Ecuador and the
Galapagos Islands. Light to gentle winds prevail elsewhere. Seas
are in the 4-6 ft range, reaching near 7 ft over the waters 
between Ecuador and the Galapagos Islands.

For the forecast, fresh to strong gap winds will develop across 
the Papagayo region tonight and continue into early next week. 
Mainly light to gentle winds are expected over the rest of the 
offshore waters through the end of the week, pulsing to moderate 
to fresh in the Gulf of Panama this weekend. NW swell associated 
with a gale- force gap wind event in the Tehuantepec region will 
propagate into the northern waters late Sat. Seas elsewhere will 
be mainly driven by a moderate S to SW swell. 

REMAINDER OF THE AREA

High pressure prevails across the waters north of 20N. The
pressure gradient between this area of high pressure and lower
pressure in the vicinity of the ITCZ is supporting moderate to
fresh winds north of the ITCZ and west of 130W. Gentle to
moderate winds prevail elsewhere. Seas are in the 7-8 ft range
north of 03N and west of 110W, and 5-7 ft elsewhere.

For the forecast, fresh to strong NE winds will develop over the
waters N of 25N and west of 125W this morning and slowly expand 
southeastward through the weekend. Associated seas will peak near
14 ft N of 25N this weekend.
