Tropical Weather Outlook
NWS National Hurricane Center Miami FL
1100 PM PDT Mon Jul 13 2026

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

Offshore of Southwestern Mexico (EP96):
A tropical wave is producing a large area of disorganized
thunderstorms and gusty winds a couple of hundred miles south of the
coast of southwestern Mexico. This system is gradually becoming
better organized, and environmental conditions appear favorable for
continued development. A tropical depression is expected to form
during the next day or so while the system moves generally
west-northwestward, staying offshore of the coast of Mexico.
* Formation chance through 48 hours...high...80 percent.
* Formation chance through 7 days...high...90 percent.

Well South of the Hawaiian Islands (CP91):
There has been little change in the organization of a broad area
of low pressure located several hundred miles south of the Hawaiian
Islands. The system is producing a small area of near gale-force
winds, mainly in gusts, over its southwestern side. However, the
system lacks a well-defined surface circulation. If the
circulation becomes better defined, a tropical depression or
tropical storm could form over the next day or two while the system
moves little. The disturbance is expected to move into less
favorable environmental conditions later this week, likely ending
its chances of development.
* Formation chance through 48 hours...high...70 percent.
* Formation chance through 7 days...high...70 percent.

Well Southwest of the Hawaiian Islands (CP90):
A trough of low pressure located several hundred miles to the
southwest of the Hawaiian Islands continues to produce an area of
disorganized showers and thunderstorms. Environmental conditions
appear favorable for gradual development, and the system could
become a tropical depression later in the week while it moves
slowly northwestward, remaining well southwest of the Hawaiian
Islands.
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 7 days...medium...50 percent.

Offshore of Southern and Southwestern Mexico:
An area of low pressure is expected to form later this week several
hundred miles south of the coast of southern Mexico. Environmental
conditions appear conducive for gradual development of this system
thereafter, and a tropical depression could form by the end of the
weekend while it moves generally west-northwestward well offshore of
Mexico.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...medium...60 percent.
