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 13

Tropical Storm Amanda Discussion Number 13
NWS National Hurricane Center Miami FL EP012026
1100 AM HST Fri Jun 05 2026
Recent visible satellite imagery shows a completely exposed center
with only a small area of convection present to the west of the
center. A SAR satellite pass from earlier this morning showed an
oblong circulation and a degraded structure on the east side
of Amanda. Due to these factors and objective and subjective
Dvorak intensity estimates of 32-36 kt, the initial intensity has
been lowered to 35 kt.
Southeasterly shear and mid-level dry air entrainment are impacting
Amanda. Small pulses of convection will be possible over the next
couple of days, which should allow Amanda to maintain tropical
cyclone status. However, increasingly hostile low- and mid-level
environmental conditions and upper-level convergence should cause
Amanda to degenerate to a post-tropical remnant low by late
Sunday.
Amanda is being steered by a large-scale ridge northeast of the
storm, and is moving slowly toward the west around 4 kt. A turn
toward the southwest is expected on Saturday as upper-level high
pressure builds northwest of the system. The official NHC forecast
has been adjusted slightly southward and lies between the Google
DeepMind and various consensus aids. By early next week, the remnant
low of Amanda is expected to move toward the west, guided by the
low-level trade winds.
