Tropical Storm Amanda Discussion Number   9
NWS National Hurricane Center Miami FL       EP012026
200 PM PDT Thu Jun 04 2026
 
Visible satellite imagery from this morning showed a partially 
exposed center of Amanda as the storm encountered southeasterly 
shear. Convection over the past several hours had faltered, however, 
a new burst of cold cloud tops has recently emerged near the center 
of the storm. This renewed convection combined with a recent 
scatterometer pass showing peak winds of 35-39 kt has indicated a 
slight increase in strength, and the initial intensity is set at 40 
kt for this advisory. 
 
Amanda is moving toward the west-northwest at around 8 kt. This 
general motion will continue into Friday as a weak upper-level ridge 
builds to the north. A turn toward the west then southwest is 
forecast later on Friday through this weekend as high pressure 
builds northwest of the system. The official NHC forecast has been 
shifted southward, and falls between the Google DeepMind and various 
consensus aids.

The environment near the storm maintains modest mid-level moisture, 
however, dry air is beginning to wrap around its southern and 
eastern periphery. After 24 h, Amanda is expected to encounter 
increasing vertical wind shear, upper-level convergence and drier 
mid-level air, leading to steady weakening this weekend. The 
official forecast calls for Amanda to weaken to a post-tropical 
remnant low later this weekend, however, the system may lose 
organized convection earlier in the forecast period.
