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 0000 UTC surface analysis and satellite imagery through
0300 UTC.

...SPECIAL FEATURES...Corrected

Tropical Depression One-E, the first depression of the 2026
eastern Pacific hurricane season, is centered near 09.7N 126.8W 
at 03/0300 UTC, moving northwest at 03 kt. Estimated minimum 
central pressure is 1008 mb. Maximum sustained wind speed is 25 
kt with gusts to 35 kt. Peak seas are around 10 ft. Satellite 
imagery shows that the depression has only become slightly better 
organized since yesterday afternoon. satellite imagery reveals 
numerous strong convection within 60 nm of the center in the W 
semicircle. Numerous moderate to isolated strong convection is 
elsewhere within 180 nm of the center in the NW semicircle. 
Scattered moderate to isolated strong convection is seen from 07N to 
10N between 124W and 127W.

Hurricane Center at website -

Tropical Depression One-E NHC Forecast/Advisory and Public
Advisory at www.hurricanes.gov for more details.

...TROPICAL WAVES...

A tropical wave has its axis along 86W southward to 03N, moving 
westward at around 5 kt. Numerous moderate to strong convection
is from 04N to 08N between 83W and 89W.

The tropical wave that was previously along 111W from 04N to 
16N is no longer identifiable as a surface feature.

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

The monsoon trough axis extends from northern Colombia westward 
to across eastern Panama and northern Costa Rica, and continues
southwestward to 08N93W, and northwest from there to low 
pressure at 12N106W and westward to 11N124W. It resumes SW of 
Tropical Depression One-E at 09N131W to low pressure near 06N138W
and to beyond the area at 05N140W. Scattered moderate to 
isolated strong convection is within 120 nm S of the trough 
between 98W-102W, within 60 nm S of the trough between 89W-98W 
and within 60 nm N and S of the trough between 113W-115W. 
Scattered moderate convection is within 120 nm N of the trough 
between 117W-124W, and from 04N to 07N between 123W-127W.

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

A broad surface ridge that is anchored by a 1027 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 
of Central America and southern Mexico late this week. 
Environmental conditions appear conducive for development of this
system thereafter, and a tropical depression could form late 
this weekend or early next week while it moves slowly 
northwestward or northward.

....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 
S to SW winds along with seas of 5 to 7 ft in long- eriod 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 of 
Central America and southern Mexico late this week. Environmental
conditions appear conducive for development of this system 
thereafter, and a tropical depression could form late this 
weekend or early next week while it moves slowly northwestward or
northward.

...REMAINDER OF THE AREA...

Please see the Special Features section for information on 
recently formed developed Tropical Depression One-E located 
about 1250 nm SW of the southern tip of Baja California, and 
that is forecast to become a tropical storm on Wed 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 Cyclone 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.

Tropical Depression One-E is forecast to move to near 10.2N 127.4W
Wed morning, then strengthen to a tropical storm near 11.1N 
128.6W Wed evening with maximum sustained 40 kt gusts 50 kt, and 
continue to gradually strengthen as it reaches near 12.0N 129.8W
Thu morning, to near 12.9N 131.1W Thu evening with maximum
sustained winds 50 kt gusts 60 kt, and maintain intensity as it 
reaches near 13.6N 132.4W Fri morning. One-E will then begin to 
weaken as it near 13.9N 133.3W Fri evening with maximum sustained
winds 45 kt gusts 55 kt, and change little in intensity as it 
moves across the far western portions of the basin Sat afternoon.
