Tropical Weather Outlook
NWS National Hurricane Center Miami FL
500 PM PDT Sat Aug 15 2026

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

Active Systems:
The National Hurricane Center is issuing advisories on Tropical
Storm Lala, located just offshore of South Point, Hawaii.

The National Hurricane Center has issued the last advisory on
Post-Tropical Cyclone Hernan, located well west-southwest of the
southern tip of the Baja California Peninsula.

South of Mexico:
An area of low pressure could form several hundred miles south of
the coast of southern Mexico around the middle portion of next week.
Some gradual development of this system is possible thereafter
while the system moves west-northwestward well south of
Mexico.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...low...30 percent.

Western Portion of the East Pacific:
An area of low pressure is expected form well to the west-southwest
of the southern tip of the Baja California Peninsula early next
week. Environmental conditions appear conducive for gradual
development of this system, and a tropical depression could form
during the middle to latter portions of next week while it moves
generally westward across the western portion of the east Pacific.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...medium...50 percent.

Post-Tropical Cyclone Hernan Discussion Number  12
NWS National Hurricane Center Miami FL       EP082026
1100 AM HST Sat Aug 15 2026
 
Hernan continues to remain a swirl of low- to mid-level clouds with 
no active deep convection. A recent ASCAT pass showed that the winds 
are around 20 to 25 kts at most in the northern portion of the 
cyclone. As a result of that, the initial intensity has been lowered 
to 25 kt. 
 
Given that the cyclone is moving into an area of higher shear and 
drier air, gradual weakening is expected over the next couple of 
days. The current forecast calls for Hernan to become a trough in 
about 60 h in agreement with the global models.
 
The initial motion is 255/10 kt. A low- to mid-level ridge to the
north should steer Hernan and its remnants westward for the next
few days. The new forecast track is similar to, but a little faster
than, the previous track.
