Tropical Weather Outlook
NWS National Hurricane Center Miami FL
1100 AM PDT Fri Jun 5 2026
For the eastern and central North Pacific east of 180 longitude:
Active Systems:
The National Hurricane Center is issuing advisories on Tropical
Storm Amanda, located well west-southwest of the southern tip of
the Baja California Peninsula.
Offshore Southern and Southwestern Mexico (EP91):
A broad area of low pressure located a few hundred miles southwest
of Zihuatanejo, Mexico is producing a large area of showers and
thunderstorms. Environmental conditions appear conducive for
development of this system, and a tropical depression is likely to
form late this weekend or early next week. The disturbance is
forecast to move northeastward then northward near the coast of
southern Mexico. Interests in southern Mexico should monitor the
progress of this system. Regardless of development, locally heavy
rainfall is possible across portions of southern Mexico through
early next week.
* Formation chance through 48 hours...medium...50 percent.
* Formation chance through 7 days...high...70 percent.
Offshore of Central America:
A trough of low pressure offshore of Central America is producing
disorganized shower and thunderstorm activity. Environmental
conditions appear conducive for gradual development of this system,
and a tropical depression could form later this weekend or early
next week if the system remains offshore. The low is forecast to
move slowly northward toward the coast of Central America.
Regardless of development, locally heavy rainfall is possible across
portions of Nicaragua, El Salvador, and Guatemala.
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 7 days...medium...60 percent.

Tropical Storm Amanda Forecast Discussion Number 12

Tropical Storm Amanda Discussion Number 12
NWS National Hurricane Center Miami FL EP012026
500 AM HST Fri Jun 05 2026
An AMSR2 satellite pass from earlier this morning showed a
well-defined center, but persistent southeasterly shear continues to
impact Amanda as the center remains on the eastern edge of the
convection. Objective and subjective Dvorak intensity estimates
range from 35-44 kt and earlier ASCAT data depicted peak winds of
38-42 kt, so the initial intensity is maintained at 40 kt.
Convection associated with Amanda has weakened over the past several
hours. Diurnal pulses of convection are expected over the next
couple of days, which should allow Amanda to maintain tropical
cyclone status. However, the storm will encounter drier mid-level
air and increasing upper-level convergence over the next 36-48 h.
Therefore, slow weakening is expected due to the increasingly
hostile environmental conditions, and Amanda is forecast to become
a post-tropical remnant low by late Sunday.
The storm is moving toward the west at around 9 kt. A mid- to
upper-level ridge northeast of Amanda will support a westward motion
today, before the storm turns to the southwest on Saturday as
ridging builds to the northwest. The official NHC forecast has been
adjusted slightly southward from the previous advisory during the
first day or so, and lies between the Google DeepMind and various
consensus aids. The remnant low is likely to turn back toward the
west by days 3-5 while being steered by the low-level trade winds.
