Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1005 UTC Mon Jun 22 2026

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
0920 UTC.

...TROPICAL WAVES...

A tropical wave is along 90W, south of 16N, moving westward at 
15-20 kt. Scattered moderate to isolated strong convection is 
present from 03N to 14N between 83W and 94W.

A tropical wave is along 97W, south of 15N, drifting westward at
5-10 kt. Scattered moderate convection is active from 06N to 11N
and between 94W and 101W.

A tropical wave is along 106W, south of 16N, moving westward at 
5-10 kt. Scattered moderate convection is observed from 06N to 
13N between 104W and 110W.

A tropical wave is along 125W, south of 17N, drifting westward 
at 5 kt. No significant convection is evident near this wave.

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

The monsoon trough extends from 10N85W to 12N110W to 09N125W. 
The ITCZ extends from 09N125W and beyond 08N140W. Aside from the 
convection associated with the tropical waves, scattered moderate
convection is evident offshore Panama and Colombia, from 07N to 
14N between 110W and 118W, and from 04N to 10N W of 130W.  

...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Moderate to fresh NW winds are across the Baja California 
offshore waters along with 5-6 ft seas. The strongest winds are 
N of Cabo San Lazaro. In the southern Gulf of California, winds
are gentle to moderate from the SE and seas are slight. Elsewhere,
light to gentle winds and slight to moderate seas prevail.

For the forecast, ridging over the eastern Pacific will support 
moderate to fresh NW winds off Baja California through tonight, 
and gentle to moderate breezes elsewhere. Winds off Baja 
California will diminish starting Tue as the high pressure 
weakens ahead of a trough moving into the area from off southern 
California. This pattern will also support moderate to fresh 
southerly winds across the Gulf of California Tue ahead of the 
trough. Looking ahead, expect fresh to strong northerly gap winds
and rough seas across the Gulf of Tehuantepec by midweek, as 
pressure lowers farther south into the tropics.

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

Moderate to fresh NE to E gap winds and seas to 5 ft are evident
across the Gulf of Papagayo region, extending downstream to 90W.
Farther south, gentle to moderate southerly winds and moderate 
seas are occurring between Ecuador and the Galapagos Islands. 
Elsewhere, light to gentle winds and slight to moderate seas 
prevail.

For the forecast, moderate to fresh easterly trade winds and 
moderate seas are expected in the Papagayo region through today. 
Winds will reach fresh to strong speeds starting tonight with 
seas building to 9 ft by late Tue. The gap winds in the Gulf of 
Tehuantepec will produce seas to 9 ft in the far offshore waters 
of Guatemala by midweek. Meanwhile, mainly moderate southerly 
winds and moderate to locally rough seas will prevail across the 
offshore waters between Ecuador and the Galapagos Islands through
Fri. 

...REMAINDER OF THE AREA...

The subtropical ridge centered well NW of our waters extends 
across the eastern Pacific waters north of 20N. Gentle to 
moderate NE to E winds and moderate seas are found from 10N to 
20N west of 115W. Farther south, long period SW swell with wave 
heights of 7-9 ft are moving into the waters south of 03N 
between 101W and 120W. Elsewhere, moderate or weaker winds and 
moderate seas prevail.

For the forecast, additional pulses of SW swell will continue to 
propagate across the forecast waters east of 125W generating 
moderate to locally rough seas. Otherwise, little changes are 
expected in winds and seas through early next week as a ridge 
remains in control of the weather pattern across the area.
Looking ahead, a tropical wave a few hundred miles off the coast
of southwestern Mexico is forecast to move westward at 10-15 kt 
across the central and western portion of the basin, and some 
slow development is possible toward the end of the week. Also, a
low pressure system is expected to form late this week several 
hundred miles offshore of the coast of southwestern Mexico. Some 
slow development of this system is possible after that time while
it moves west-northwestward at 10-15 kt.
