Tropical Weather Outlook
NWS National Hurricane Center Miami FL
500 AM PDT Sun Aug 3 2025

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

Active Systems:
The National Hurricane Center is issuing advisories on Tropical
Storm Gil, located well east of the Hawaiian Islands.

Central East Pacific (EP90):
Disorganized showers and thunderstorms located well west-southwest
of the southwestern coast of Mexico are associated with a broad area
of low pressure. Environmental conditions are conducive for
development of this system, and a tropical depression is likely to
form during the next day or two while the system moves
west-northwestward at 10 to 15 mph. For additional information,
including gale warnings, please see High Seas Forecasts issued by
the National Weather Service.
* Formation chance through 48 hours...high...90 percent.
* Formation chance through 7 days...high...90 percent.

South of Southern Mexico:
An area of low pressure is forecast to form offshore of the coast of
Central America and southern Mexico by midweek. Environmental
conditions appear conducive for some development, and a tropical
depression could form later this week as the system moves generally
west-northwestward at 10 to 15 mph.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...medium...50 percent.

A timely ASCAT pass revealed peak winds of around 45 kt in the northern semicircle. Subjective Dvorak current intensity estimates from TAFB and SAB range from 3.0/45 kt to 3.5/55 kt, which are slightly higher than objective satellite estimates. Based on a blend of these data and the ASCAT pass, the initial intensity is set at 50 kt. The initial motion is estimated at 290/16 kt. Gil is being steered by a mid-level ridge to its north, and this general motion is expected to continue Sunday. A gradual decrease in forward speed is anticipated by Monday, followed by a turn toward the west as the shallow remnant low becomes steered by the low-level flow. The updated track forecast remains close to the previous advisory and continues to follow the tightly clustered guidance envelope. Continued movement over progressively cooler waters, intrusion of dry mid-level air, and the onset of increasing west-southwesterly shear should accelerate Gil’s weakening trend. Simulated satellite imagery from global models continues to suggest that Gil will lose its deep convection and become post-tropical late Sunday, or in about 24 hours. The system is then forecast to gradually spin down and dissipate within a few days, likely by day 4, as it opens into a trough northeast of the Hawaiian Islands.

Based on Dvorak estimates of T3.0/4.0 from TAFB and T3.5/3.5 from SAB, the intensity is lowered to 55 kt. Sea surface temperatures ahead of Gil will be getting colder by another degree or two, and the storm will be running into a region of moderate to strong southwesterly shear in 24-48 hours. Gil is likely to lose organized convection, and thus become post-tropical, in about 24 hours, with continued weakening thereafter. The storm continues to move quickly west-northwestward at 295/18 kt. The ridge north of Gil is forecast to weaken during the next couple of days, which should cause a gradual decrease in forward speed. A turn toward the west is forecast in about 48 hours as the remnant low is steered by the low-level flow. The NHC track forecast is slightly south of the previous forecast, leaning toward the latest HCCA and AI guidance. Global models are in good agreement that the remnant low will open up into a trough by day 4 (Wednesday) northeast of the Hawaiian Islands.
