000 WTPZ41 KNHC 060235 TCDEP1 Tropical Storm Amanda Discussion Number 14 NWS National Hurricane Center Miami FL EP012026 500 PM HST Fri Jun 05 2026 Amanda has produced a modest increase in deep convection during the past few hours, with cloud-top temperatures cooling to around -80C. However, this renewed burst of convection remains confined primarily to the western semicircle, with the low-level circulation center located near or beneath the eastern edge of the deep convection. Subjective Dvorak estimates from TAFB, along with objective intensity estimates from UW-CIMSS, range from 35 to 40 kt. Given the recent increase in convection and these estimates, 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 cyclone should continue to steer Amanda generally toward the southwest through the weekend. As the system weakens and becomes increasingly shallow, it should become embedded within the low-level trade wind flow, resulting in a continued south-of-west motion during the next several days. The latest track guidance remains in good agreement, and the NHC forecast track is little changed from the previous advisory and lies near the consensus aids. Persistent southeasterly shear, increasing dry-air entrainment, and increasing upper-level convergence are expected to continue limiting convective organization. While simulated satellite imagery from the dynamical models suggests occasional bursts of convection will persist through the next couple of days, these episodes are unlikely to result in any significant organization. As Amanda gradually continues southwestward and becomes increasingly shallow, steady weakening is expected. The NHC intensity forecast remains near the consensus guidance and continues to show Amanda degenerating into a post-tropical remnant low on Sunday.
