Tropical Weather Outlook
NWS National Hurricane Center Miami FL
1100 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):
Showers and thunderstorms associated with a broad area of low 
pressure located a few hundred miles south-southwest of Zihuatanejo, 
Mexico, are beginning to show signs of organization. Environmental 
conditions appear conducive for additional development, and a 
tropical depression is likely to form within the next day or so. 
The disturbance is forecast to move northeastward and then 
northward, and approach the coast of southern Mexico Sunday night 
and Monday. Interests in southern Mexico should monitor the progress 
of this system. Regardless of development, heavy rainfall and 
life-threatening flash flooding are 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 (EP92):
Showers and thunderstorms associated with a broad area of low 
pressure offshore of Central America have increase in coverage 
since yesterday.  Environmental conditions appear conducive for 
development and a tropical depression is likely to form while the 
system moves slowly northward toward the coast of Central America.
Interests along the Pacific coasts of northwestern Costa Rica, 
Nicaragua, Honduras, and El Salvador should monitor the progress of 
this system.  Regardless of development, heavy rainfall and 
life-threatening flash flooding are possible across portions of 
Costa Rica, Nicaragua, El Salvador, and Guatemala through early 
next week. 
* Formation chance through 48 hours...high...70 percent.
* Formation chance through 7 days...high...70 percent.

Tropical Depression Amanda Discussion Number  17
NWS National Hurricane Center Miami FL       EP012026
1100 AM HST Sat Jun 06 2026
 
Since early this morning, deep convection associated with Amanda has
weakened and separated from the low-level center due to east-
southeasterly shear.  This has resulted in the system becoming a
swirl of low- to mid-level clouds.  A timely 1737 UTC ASCAT-B
overpass revealed a peak wind of 27 kt. Therefore, the initial
intensity has been lowered to possibly generous 30 kt.
 
Continued east-southeasterly shear and a dry mid-level environment
are expected to cause gradual weakening over the next several days
despite the system remaining over SSTs of 27-28C.  Those warm
waters will likely result in the system producing intermittent
bursts of convection during the next day or so, but they are likely
to become less and less organized, resulting in Amanda become a
post-tropical remnant low in 36-48 hours.
 
Amanda is moving southwestward or 215/4 kt.  A high pressure
ridge to the north of the cyclone should steer it southwestward or
west-southwestward through the next several days. The NHC forecast
lies near the latest Google Deep Mind ensemble mean and HCCA 
multi-model consensus.
