Tropical Weather Outlook
NWS National Hurricane Center Miami FL
500 AM PDT Tue Aug 26 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 east Pacific basin several hundred
miles southwest of the southern tip of the Baja California
peninsula.

Well Southeast of the Hawaiian Islands:
An area of low pressure located several hundred miles southeast of
the Hawaiian Islands continues to produce disorganized showers and
thunderstorms. Environmental conditions appear conducive for some
gradual development of this system, and a tropical depression could
form late this week, while it moves westward at 10 to 15 mph across
the central Pacific basin.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 7 days...medium...40 percent.

Well Southwest of the Baja California Peninsula:
An area of disorganized showers and thunderstorms located a few
hundred miles south of the coast of southern Mexico is associated
with a tropical wave. Some slow development of this system is
possible late this week and into the weekend while it moves
westward to west-northwestward at 10 to 15 mph across the central
part of the eastern Pacific basin.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...low...30 percent.

South of Southern Mexico:
An area of low pressure could form this weekend offshore of the
coast of Central America and southern Mexico. Environmental
conditions appear conducive for some gradual development of this
system early 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...20 percent.

Recent microwave imagery shows that Juliette is still trying to develop a small inner core, which has not become better established since the previous advisory. Unfortunately, scatterometer missed tonight given the small size of the system it fell within the data gap. There is a bit of a range from subjective and objective intensity estimates this cycle between 44 to 65 kt. Using a blend of these estimates, the initial intensity for this advisory is held at 55 kt. The system is moving west-northwestward at an estimated motion of 290/ 11 kt. The storm is being steered along the southwestern edge of a mid-level ridge located to the north. A gradual turn to the northwest then north-northwest is anticipated as a weakness in the ridge develops over the next couple of days. The NHC forecast track was nudged slightly to the right in the short term between the consensus aids on the right with Google DeepMind and EMXI on the left. Juliette should remain within a favorable environment, with warm sea surface temperatures and light to moderate wind shear for the next 18-24 h , which will allow for some strengthening. However, by early Wednesday the system will be crossing into cooler sea surface temperatures, and into a drier airmass. Latest SHIPS model guidance depicts wind shear also increases in about 48 h. The latest NHC intensity forecast lies near the consensus aids, and shows some strengthening possible today, although since the inner core has not established, the peak intensity is now just below hurricane strength. A gradual weakening trend is then forecast between 24-36 h, followed by a faster rate of weakening beyond 36 h. Juliette is forecast to become a remnant low by 60 h, before opening into a trough and dissipating by day 4.

A microwave pass from a few hours ago suggested that the storm was developing an inner core, and recent infrared satellite images indicate that banding features are increasing south of the center. The Dvorak estimates from TAFB, SAB, and CIMSS have all increased to 3.5/55 kt, and therefore, the initial wind speed is increased to that value. Juliette is expected to remain in favorable conditions to strengthen for about another day, and it seems likely that it will become a hurricane on Tuesday. However, the strengthening trend should end by Tuesday night when the storm is forecast to cross the 26 C SST isotherm and then move into an environment of drier air and stronger shear. Juliette is expected to become a remnant low in about 3 days when it is forecast to be over cool 22 C waters, and dissipate entirely this weekend. The NHC intensity forecast is a blend of the HCCA and IVCN models. The storm is moving west-northwestward at 12 kt on the southwest side of a mid-level ridge. A gradual turn to the northwest and then the north-northwest with a notable reduction in forward speed is expected over the next few days as Juliette moves toward a weakness in the ridge. The NHC track forecast is largely an update of the previous one and lies on the western side of the guidance envelope, in best agreement with EMXI and the Google DeepMind models.
