500 AM PDT Wed Oct 21 2026

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

South of Southern Mexico (EP94):
Satellite imagery indicates that a low-pressure system located a few
hundred miles south-southwest of the Gulf of Tehuantepec is
producing a large area of showers and thunderstorms. This activity
continues to become better organized, and if current trends
persist, a tropical depression is expected to form later today. The
system is expected to move westward to west-northwestward at around
10 mph during the next few days, well offshore the coast of
southern Mexico. For additional information, including Gale
Warnings, see the High Seas Forecast issued by the National Weather
Service.
* Formation chance through 48 hours...high...near 100 percent.
* Formation chance through 7 days...high...near 100 percent.

Western Central Pacific:
An area of low pressure is forecast to form in the far western
central Pacific a few hundred miles southwest of Johnson Atoll late
this weekend of early next week. Environmental conditions appear
conducive for some gradual development thereafter while the system
moves generally eastward to east-northeastward.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...low...20 percent.
