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 1800 UTC surface analysis and satellite imagery through
2100 UTC.

...SPECIAL FEATURES...

Tropical Depression One-E: The first tropical depression of the
2026 Eastern Pacific hurricane season has formed in the western
portion of the basin this afternoon. Newly-formed Tropical 
Depression One-E is centered near 9.4N 126.7W at 02/2100 UTC, 
moving west at 3 kt. Estimated minimum central pressure is 1008 
mb. Maximum sustained wind speed is 25 kt with gusts to 35 kt. 
Peak seas are near 10 ft. Numerous strong convection is noted 
from 08N to 11N between 125W and 131W. One-E is forecast to move 
to 9.9N 127.1W Wed morning, then strengthen to a tropical storm 
near 10.6N 128.2W Wed afternoon. One-E is forecast to reach 11.5N
129.4W Thu morning, 12.6N 130.8W Thu afternoon, 13.3N 132.2W Fri
morning, and 13.7N 133.3W Fri afternoon. One-E will change 
little in intensity as it moves westward across the far western 
portions of the basin Sat afternoon.

Advisory at www.hurricanes.gov for more details.

...TROPICAL WAVES...

A tropical wave has now fully emerged into the eastern Pacific
and now has an axis along 86W southward to 03N, moving westward
at around 5 kt. Scattered moderate to isolated strong convection
is noted N of 04N between 81W and 91W. 

A tropical wave has its axis along 111W, from 04N to 16N, moving
westward at around 5 kt. Scattered moderate convection is noted 
from 07N to 13N between 103W and 113W.

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

The monsoon trough axis extends from 10N82W to newly formed
Tropical Depression One-E at 09N127W to 05N140W. Scattered 
moderate convection is noted within 180 nm N of the trough 
between 131W and 138W and from 03N to 09N between 116W and 122W.
Scattered moderate convection has also developed from 07N to 14N
between 91W and 101W. 

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

A broad surface ridge that is anchored by a 1026 mb high center 
N of the area near 33N135W stretches southeastward to the
Revillagigedo Islands. The pressure gradient between this ridge
and a surface trough along the Gulf of California is maintaining
mainly moderate NW winds over the Baja California offshore 
waters, with seas of 5 to 7 ft. Inside the Gulf of California,
light to gentle winds prevail, with seas of 1 to 3 ft, except for
3 to 5 ft in S to SW swell near the entrance to the Gulf. For 
the remainder of the offshore waters, light to gentle winds 
dominate along with 5 to 7 ft seas primarily in long-period S to 
SW swell, including the Gulf of Tehuantepec.

For the forecast, NW swell will move through the waters offshore
Baja California Norte Wed night through early on Sat, decaying 
afterward. An area of low pressure is forecast to form offshore 
Central America and southern Mexico late this week or this 
weekend. Environmental conditions appear conducive for some 
development of this system thereafter, and a tropical depression 
could form early next week while it moves slowly north- 
northwestward. 

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

Mainly light and variable winds are over the Central American 
offshore waters under a weak pressure pattern along with 
moderate seas of 5 to 7 ft in long-period S to SW swell. The
exception is fresh gap winds in the Papagayo region. Gentle 
south winds along with seas of 5 to 7 ft in long- period SW 
swell are over the waters S of the monsoon trough between the 
Galapagos Islands and Ecuador.

For the forecast, pulses of moderate to fresh gap winds will 
occur the the Papagayo region tonight and Wed night. Long period 
SW swell is forecast to enter the southern Galapagos adjacent 
waters tonight, then begin to subside Thu afternoon. Looking 
ahead, an area of low pressure is forecast to form offshore 
Central America and southern Mexico late this week or this 
weekend. Environmental conditions appear conducive for some 
development of this system thereafter, and a tropical depression 
could form early next week while it moves slowly north-
northwestward. 

...REMAINDER OF THE AREA...

Please see the Special Features section for information newly
developed Tropical Depression One-E, that is forecast to become a
tropical storm this week over the far western portions of the
basin. 

Otherwise, high pressure dominates waters N of the monsoon 
trough, with the pressure gradient between the high pressure and 
lower pressure within the monsoon trough generally allowing for 
moderate to locally fresh trade winds N of the monsoon trough to 
25N. Seas over these waters are in the 7 to 9 ft range in a mix 
of trade wind waves and NW to N swell. Mainly gentle winds are S
of the monsoon trough. Seas over these waters are generally 5 to
7 ft, except for S of the Equator, where long- period southerly 
swell is causing rough seas W of 100W. 

The aforementioned high pressure will weaken some toward the end of 
the week as Tropical Depression One-E tracks NW over the western
portion of the area, resulting a a lessening of the trade winds E
of 130W. These winds will become light from 04N to 12N between
120W to 130W, with seas subsiding to moderate. Little change is
expected elsewhere.
