NWS National Hurricane Center Miami FL
1005 UTC Sun Apr 10 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.

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

A surface trough extends from 07N78W to 05N82W to 05N96W. The 
ITCZ continues from 05N96W to 08N119W. It resumes from 05N128W 
to 05N140W. Scattered moderate isolated strong convection is 
noted from 01N to 08N east of 84W. Scattered moderate convection
is noted from 05N to 10N between 97W and 106W, from 05N to 11N
between 110W and 130W, and from 03N to 07N between 130W and 140W. 

OFFSHORE WATERS WITHIN 250 NM OF MEXICO

High pressure across the Gulf of Mexico has shifted eastward.
This has loosened the pressure gradient across the Tehuantepec
region, and winds have diminished below gale- force. Strong to
near gale- force winds now prevail, with seas peaking near 10
ft. Winds and seas will continue to decrease today. Seas 
generated from this gale- force gap wind event have spread far 
from the Tehuantepec region, with seas greater than 8 ft reaching
as far west as 105W. These seas will subside today.

Aside from conditions in the Gulf of Tehuantepec, moderate to 
fresh NW winds prevail west of Baja California Norte. Light to 
gentle winds prevail elsewhere across the open waters off Mexico.
Fresh to strong winds prevail over the northern Gulf of 
California, with moderate winds elsewhere over the Gulf. Seas are
6-13 ft west of Baja California Norte and 4-6 ft elsewhere 
offshore Mexico. Seas are in the 3-4 ft range in the northern 
Gulf of California and 2-3 ft elsewhere in the Gulf.

For the forecast, fresh to strong winds will persist across the 
northern Gulf of California through Mon night. Northerly swell 
propagating across the waters off Baja California Norte will 
spread southward across the waters off Baja California Sur today.
A cold front will move into the northern portion of the area by 
Tue morning. Fresh to strong NW winds are likely behind the front
to the west of Baja California Norte. A reinforcing set of 
northerly swell will enter the area behind the front. This will 
maintain wave heights in excess of 8 ft west of the Baja 
California peninsula through much of next week.of 8 ft west of 
Baja California through much of next week. 

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

Fresh to strong winds prevail over the Gulf of Papagayo region, 
with moderate to fresh winds over the Gulf of Panama. Light to 
gentle winds prevail elsewhere. Seas are in the 4-6 ft range, 
except 6-8 ft in the Papagayo region. Seas are 7-8 ft in N swell
well offshore of Guatemala due to the gap wind event in the Gulf
of Tehuantepec.

For the forecast, fresh to strong winds in the Papagayo region 
will continue into next week, reaching near gale force late 
tonight through early Sun. Mainly light to gentle winds are 
expected over the rest of the offshore waters, pulsing to fresh 
in the Gulf of Panama into early next week. S to SW swell will 
increase seas Mon to the south of the Galapagos Islands and to 
the west of Ecuador. 

REMAINDER OF THE AREA

Strong high pressure of 1038 mb is centered north of the area 
near 38N138W. This area of high pressure is generating a tight 
pressure gradient that is supporting fresh to strong NE winds 
over the northwest portion of the area. Seas in this area are in 
the 10-14 ft range. Moderate to locally fresh trade winds are 
elsewhere north of the ITCZ and west of 130W, with gentle to 
moderate winds prevailing elsewhere. Seas are in the 6-8 ft 
range. Southern Hemisphere swell is affecting the area south of 
the Equator between 110W-120W, with 8-9 ft seas.

For the forecast, the area of fresh to strong winds over the
northwest part of the area will continue through the remainder of
the weekend before starting to diminish early next week. Swell 
generated from these winds will spread southward, with seas 
greater than 8 ft covering much of the waters north of 10N and 
west of 115W by Mon night. A weak cold front will enter the 
northern waters by Tue morning. The front will bring a 
reinforcing northerly swell to the area east of 125W and north of
22N Tue through Wed. Southerly swell from the Southern 
Hemisphere will continue to affect areas south of 05N between the
Galapagos Islands and 120W through the early part of next week.
