Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1605 UTC Thu Mar 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 1200 UTC surface analysis and satellite imagery through
1500 UTC.

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

A surface trough extends from Panama near 08N78W to 02N81W. 
Another trough extends from 06N89W to 04N113W. The ITCZ extends 
from 04N113W to beyond 06N140W. Scattered moderate convection is
noted within 90 nm on either side of the boundaries. 

OFFSHORE WATERS WITHIN 250 NM OF MEXICO

A surface ridge continues to extend from strong high pressure 
across the NE Pacific south and southeastward through 30N134W to
near 19N116W. This is leading to mainly gentle winds with seas of
3 to 6 ft.

Gentle to moderate winds will prevail over most of the area 
through late week. New northerly swell will raise seas to 9 ft 
offshore Baja California Norte today into Fri. A weak cold front
will move down the Gulf of California through tonight and bring 
strong winds to the Gulf behind it into Sat. Looking ahead, 
strong gales will develop in the Gulf of Tehuantepec Sat and 
continue into Sun night. 

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

A weak pressure gradient through the area is leading to mainly
gentle winds with seas of 3 to 5 ft. Moderate E winds are pulsing
in the Gulf of Papagayo.

Gap winds across the Papagayo region will diminish tonight. Mainly
gentle winds will prevail elsewhere. Fresh to locally strong gap
winds will pulse over the Papagayo region Sun, with moderate to 
fresh winds likely to develop Sun night in the Gulf of Panama.

REMAINDER OF THE AREA

High pressure is centered near 38N133W and analyzed at 1028 mb. 
A broad ridge extends southward between 105W and beyond 140W. 
The pressure gradient south of the ridge is supporting moderate 
to fresh NE to E winds between the ITCZ and 20N, to the W of 
120W, with gentle to moderate N to NE winds to the N. Seas are 8 
to 10 ft in mixed swell across the trade wind zone, and 5 to 8 
ft elsewhere W of 118W. To the S of the ITCZ, gentle to moderate 
E to SE winds prevail with seas of 5 to 7 ft.

The pressure gradient S of 25N and W of 125W will support fresh 
trades and seas of 8 to 10 ft for the remainder of the week. 
Winds and seas will diminish this weekend as a cold front 
approaches far NW portions of the discussion area.
