Tropical Weather Outlook
NWS National Hurricane Center Miami FL
500 AM PDT Sat Jun 6 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 east-southeast of the Hawaiian Islands.
Offshore Southern and Southwestern Mexico (EP91):
Overnight satellite-derived wind data depict an elongated area of
low pressure located a few hundred miles southwest of Zihuatanejo,
Mexico. Shower and thunderstorm activity associated with the
system has gradually increased during the past several hours.
Environmental conditions appear conducive for development of this
system, and a tropical depression is likely to form Sunday or early
next week. The disturbance is forecast to move generally northward
near the coast of southern Mexico during the next few days.
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...high...70 percent.
* Formation chance through 7 days...high...70 percent.
Offshore of Central America:
Disorganized showers and thunderstorms offshore of Central America
are associated with a trough of low pressure. Environmental
conditions appear conducive for gradual development of this system
while it moves slowly northward toward the coast of Central
America. If the system remains offshore, a tropical depression
could form by early next week. Regardless of development, locally
heavy rainfall is possible across portions of Costa Rica, Nicaragua,
El Salvador, and Guatemala through early next week.
* Formation chance through 48 hours...medium...50 percent.
* Formation chance through 7 days...medium...60 percent.

Tropical Storm Amanda Forecast Discussion Number 15

Tropical Storm Amanda Discussion Number 15
NWS National Hurricane Center Miami FL EP012026
1100 PM HST Fri Jun 05 2026
Amanda's overall structure has changed little since the previous
advisory. Deep convection continues over and west of the low-level
circulation center due to the persistent moderate southeasterly
shear. Subjective Dvorak estimates from TAFB and objective intensity
estimates from UW-CIMSS range from 35 to 40 kt. Given the current
satellite presentation and continuity from the previous forecast,
the initial intensity is held at 35 kt.
Amanda is moving toward the southwest, or 230/4 kt. A low- to
mid-level ridge building north of the system is expected to remain
the primary steering mechanism, resulting in continued southwestward
motion through the weekend. As Amanda gradually weakens and becomes
increasingly shallow, it should become embedded within the low-level
trade wind flow. The latest track guidance remains tightly
clustered, and the NHC forecast track is essentially unchanged from
the previous advisory.
Persistent southeasterly shear, dry-air entrainment, and increasing
upper-level convergence are expected to continue limiting convective
organization. Simulated satellite imagery from the dynamical models
generally agrees, showing only occasional bursts of convection with
no significant organization. The NHC intensity forecast remains near
the consensus guidance and continues to show Amanda steadily
weakening over the weekend, then degenerating into a post-tropical
remnant low late Sunday.
