000 WTPZ41 KNHC 051446 TCDEP1 Tropical Storm Amanda Discussion Number 12 NWS National Hurricane Center Miami FL EP012026 500 AM HST Fri Jun 05 2026 An AMSR2 satellite pass from earlier this morning showed a well-defined center, but persistent southeasterly shear continues to impact Amanda as the center remains on the eastern edge of the convection. Objective and subjective Dvorak intensity estimates range from 35-44 kt and earlier ASCAT data depicted peak winds of 38-42 kt, so the initial intensity is maintained at 40 kt. Convection associated with Amanda has weakened over the past several hours. Diurnal pulses of convection are expected over the next couple of days, which should allow Amanda to maintain tropical cyclone status. However, the storm will encounter drier mid-level air and increasing upper-level convergence over the next 36-48 h. Therefore, slow weakening is expected due to the increasingly hostile environmental conditions, and Amanda is forecast to become a post-tropical remnant low by late Sunday. The storm is moving toward the west at around 9 kt. A mid- to upper-level ridge northeast of Amanda will support a westward motion today, before the storm turns to the southwest on Saturday as ridging builds to the northwest. The official NHC forecast has been adjusted slightly southward from the previous advisory during the first day or so, and lies between the Google DeepMind and various consensus aids. The remnant low is likely to turn back toward the west by days 3-5 while being steered by the low-level trade winds.
