Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1005 UTC Fri Apr 15 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 08N78W to 09N108W to 06N130W. The 
ITCZ extends from 06N130W to 04N140W. Scattered moderate 
convection is noted within 100 nm on either side of the trough 
mainly E of 100N and from 02N to 15N between 103W-124W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO

The pressure gradient between 1023 mb high pressure centered 
near 29N132W and lower pressure across Mexico is supporting 
fresh to locally strong NW winds N of Punta Eugenia in Baja 
California Norte, and moderate winds prevail off Baja California
Sur and in the southern half and entrance of the Gulf of 
California. Light to gentle variable winds are elsewhere in the 
SW offshore waters of Mexico. Seas are in the 6 to 8 ft range 
offshore of the Baja California peninsula, 4 to 5 ft in the S and
SW Mexican offshore waters, and 1 to 3 ft over the central and 
southern Gulf of California. Elsewhere, patchy areas of haze are 
possible near the coast of SW Mexico due to nearby agricultural 
fires.

For the forecast, fresh to strong NW winds N of Punta Eugenia and 
northerly swell west of the Baja California peninsula will
diminish by this evening. Fresh to strong NW winds of Baja 
California Norte will resume on Sat night and continue through 
early next week. Moderate NW winds in the Gulf of California will
develop on Sun, increasing to fresh speeds Sun evening.

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

Gentle to moderate winds are noted over the Papagayo region 
offshore Nicaragua and between Ecuador and the Galapagos 
Islands. Light to gentle winds prevail elsewhere. Seas are in the
4 to 6 ft range in decaying S to SW swell. 

For the forecast, high pressure north of the area will support 
pulses of fresh to strong winds into the Papagayo region 
offshore Nicaragua through early Sun. Gentle winds in the Gulf of
Panama will increase to moderate speeds this weekend while 
gentle to moderate S winds will prevail between Ecuador and the 
Galapagos Islands. Light to gentle winds are expected elsewhere.
Moderate SW swell offshore of Ecuador to the Galapagos Islands 
will subside today. 

REMAINDER OF THE AREA

High pressure prevails over the NW forecast waters. The pressure
gradient between this area of high pressure and lower pressure 
in the vicinity of the ITCZ and equatorial trough is supporting 
moderate to fresh anticyclonic flow north of the ITCZ and west of
110W. Seas within this area are in the 6 to 8 ft range. Winds 
are gentle to moderate elsewhere with seas to 7 ft.

For the forecast, conditions are expected to gradually improve, 
with the majority of 8 ft seas expected to subside tonight while 
fresh winds diminish also. Fairly tranquil marine conditions 
will then prevail through the weekend.
