000 WTPZ41 KNHC 052036 TCDEP1 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.
