For the eastern and central North Pacific east of 180 longitude:

Western East Pacific (EP93):
Recent satellite wind data indicate that the disturbance located
about 925 miles southwest of the southern tip of the Baja California
peninsula continues to lack a well-defined low-level circulation.
However, shower and thunderstorm activity continues to show signs of
organization. Environmental conditions appear conducive for
additional development of this system, and a tropical depression is
expected to form during the next day or so while moving westward at
around 10 mph across the western part of the eastern Pacific basin.
The system is likely to cross into the central Pacific basin by the
middle to latter part of next week.
* Formation chance through 48 hours...high...80 percent.
* Formation chance through 7 days...high...90 percent.

South of Southern Mexico:
A tropical wave is producing a large area of disorganized showers
and thunderstorms south of southern Mexico. An area of low pressure
is expected to form from this system early next week, and it is
likely to become a tropical depression by the middle of next week
while moving west-northwestward or northwestward at 10 to 15 mph
just offshore of the southwestern coast of Mexico.
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 7 days...high...80 percent.

Tropical Storm Juliette Forecast Discussion Number 14

3 weeks ago
Issued at 800 PM PDT Wed Aug 27 2025 000 WTPZ45 KNHC 280238 TCDEP5 Tropical Storm Juliette Discussion Number 14 NWS National Hurricane Center Miami FL EP102025 800 PM PDT Wed Aug 27 2025 Satellite imagery shows that Juliette’s low-level circulation is now fully exposed southwest of a diminishing area of convection, which has been fading quickly under persistent southwesterly shear and a dry mid- to upper-level environment. A 1719 UTC ASCAT-C pass indicated peak winds near 40 kt, consistent with the latest objective and subjective intensity estimates, so the initial intensity is held at 40 kt for this advisory. Further weakening is anticipated as Juliette remains embedded in increasing shear, cool waters, and a stable, dry environment. The system is expected to transition into a remnant low late Thursday and dissipate within a couple of days. Juliette is moving north-northwestward, or 330/8 kt, into a weakness in the subtropical ridge. The forecast track has been nudged slightly to the left of the previous advisory and lies close to the consensus aids. As Juliette degenerates into a shallow system, most of the global models indicate the remnant low will gradually bend leftward while becoming steered primarily by the low-level flow by the weekend. Global models also suggest that residual mid- to upper-level moisture associated with Juliette will lift northeastward over portions of northwestern Mexico and the southwestern United States, potentially increasing rainfall chances.

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
500 PM PDT Wed Aug 27 2025

For the eastern and central North Pacific east of 180 longitude:

Active Systems:
The National Hurricane Center is issuing advisories on Tropical
Storm Juliette, located in the eastern Pacific basin several hundred
miles west of the southern tip of the Baja California peninsula.

Well South of the Hawaiian Islands:
A trough of low pressure located several hundred miles south of the
Hawaiian Islands continues to produce disorganized showers and
thunderstorms. Environmental conditions are only marginally
conducive for some slow development of this system over the next few
days while it moves westward at around 15 mph across the central
Pacific basin. By Saturday, conditions are expected to become
unfavorable for further development.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 7 days...low...10 percent.

Well Southwest of the Baja California Peninsula:
A tropical wave located several hundred miles southwest of the coast
of southwestern Mexico continues to produce a large area of
disorganized showers and thunderstorms. Environmental conditions
appear favorable for gradual development of this system during the
next few days, and a tropical depression is likely to form over the
weekend while the system moves westward to west-northwestward at
around 15 mph across the central to western part of the eastern
Pacific basin.
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 7 days...high...70 percent.

South of Southern Mexico:
Another area of low pressure could form this weekend offshore of the
coast of southern Mexico. Environmental conditions appear conducive
for some gradual development of this system during the early and
middle portions of next week while it moves generally
west-northwestward at 10 to 15 mph.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...low...30 percent.

Tropical Storm Juliette Forecast Discussion Number 13

3 weeks ago
Issued at 200 PM PDT Wed Aug 27 2025 000 WTPZ45 KNHC 272036 TCDEP5 Tropical Storm Juliette Discussion Number 13 NWS National Hurricane Center Miami FL EP102025 200 PM PDT Wed Aug 27 2025 GOES-18 imagery indicates that convection associated with Juliette continues to gradually decrease, and the cloud tops on IR imagery are gradually warming. However, there is an area of convection about 70 n mi wide in the NE quadrant, with the low-level center currently at the southwestern edge of the convective area. The latest subjective Dvorak CI numbers from TAFB and SAB are 3.0/45 kt, while objective intensity estimates from UW-CIMSS have a wider range (35-50 kt). A 1719 UTC ASCAT-C pass over the cyclone showed several 34-36 kt vectors in the northeast quadrant. The initial intensity is nudged downward to 40 kt for this advisory. Juliette is moving over cold sea surface temperatures of 23-24C, and the cyclone is forecast to reach water temperatures colder than 22C in 6-12 h. Juliette is also now reaching an area of increasing southwesterly wind shear, along with a drier, stable low- to mid-tropospheric environment. These negative factors will cause Juliette to continue weakening, and the cyclone should become a remnant low in about 24 h. Afterward, Juliette should open into a trough by late Friday. The NHC intensity forecast is near the middle of the guidance envelope, with slightly faster weakening shown compared to the previous advisory. The initial motion is estimated to be north-northwestward, or 330/12 kt. This motion should continue for the next 12-18 h while Juliette moves further into a growing weakness in the mid-level subtropical ridge. As Juliette degenerates into a vertically shallow cyclone on Thursday, a slower forward motion toward the north is expected while being steered by the weaker low-level flow. The official track forecast has been adjusted slightly to the left of the previous track, and lies close to the various consensus aids. Global models predict that residual mid- to upper-tropospheric moisture will be advected toward portions of northwestern Mexico and the southwestern U.S., potentially increasing humidity conditions and enhancing local monsoonal rainfall toward the end of the week.
