NWS National Hurricane Center Miami FL
1005 UTC Fri Apr 29 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
0900 UTC.

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

A surface trough extends from near the Costa Rica-Panama border 
across 09N105W to 08N123W. An ITCZ continues from 08N123W to 
beyond 140W at 09N. Scattered moderate to isolated strong 
convection is seen from 07N to 13N between 102W and 116W. 
Scattered moderate convection is noted from 03N to 07N between 
78W and 91W, and from 04N to 11N west of 130W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO

A 1028 mb high off the southern California coast continues to 
channel moderate to fresh NW to N winds across the waters west 
and southwest of the Baja California peninsula, and also over 
the central Gulf of California. Seas range from 6 to 9 ft near 
Baja and 1 to 3 ft across the Gulf of California. Gentle to 
moderate winds with 4 to 6 ft seas are present across the 
southern Mexican offshore waters, except fresh with locally 
strong northerly winds and seas at 5 to 6 ft near the Gulf of 
Tehunatepec.

For the forecast, moderate to fresh NW to N winds will persist 
west of Baja California Norte through Sun afternoon, and west and
southwest of Baja California Sur through Sat afternoon; then 
remain at gentle to moderate for both locations most of next 
week. Fresh to locally strong northerly winds will linger over 
the central Gulf of California and near the Gulf of Tehuantepec 
until sunrise, then become gentle to moderate later this morning.
Long-period moderate NW swell will remain west of Baja California
Norte through Mon, and Baja California Sur through Sun morning; 
then gradually subside afterward.

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

Fresh with locally strong easterly winds and 5 to 7 ft seas are 
occurring offshore from the Papagayo region and southern 
Nicaragua. Gentle to moderate southerly winds and seas at 6 to 7
ft are evident between the west of coast of Colombia and 
Galapagos Islands. Light to gentle winds and seas of 4 to 5 ft 
prevail across the remainder of the offshore waters.

For the forecast, fresh with locally strong easterly winds 
offshore from the Papagayo region and southern Nicaragua will 
gradually diminish to between gentle and moderate, and shift to 
the south by late Sat afternoon. Long-period moderate S to SW 
swell across the much of the region will subside to light by 
midweek next week, before increasing again toward the next 
weekend.

REMAINDER OF THE AREA

Tight pressure gradient between a 1028 mb high off the southern
California coast and an ITCZ near 08N is sustaining moderate to 
fresh NE to ENE trades from N of the ITCZ to 25N and W of 123W. 
Long-period NW to N primary swell in this area is maintaining 
seas at 7 to 8 ft. Gentle to moderate E to SE winds along with 
seas of 5 to 7 ft in moderate long-period S to SW swell are 
noted elsewhere.

For the forecast, northerly swell and 5 to 8 ft seas will 
continue across the western forecast waters through tonight, 
mostly N of 09N and W of 120W. Then seas will increase slightly 
to between 6 and 9 ft on Sat before gradually subsiding early 
next week. Elsewhere, southerly swell should keep 5 to 7 ft seas 
through midweek next week.
