Issued at 800 PM PDT Thu Aug 05 2021 000 WTPZ43 KNHC 060234 TCDEP3 Tropical Depression Hilda Discussion Number 26 NWS National Hurricane Center Miami FL EP082021 800 PM PDT Thu Aug 05 2021 The low-level center of Hilda has been partially exposed in visible satellite imagery as the system struggles to sustain any organized convection. Although a scatterometer pass around 1830 UTC showed winds near tropical-storm-force in the northeastern quadrant, the satellite presentation of Hilda has continued to deteriorate during the past several hours. Therefore, the initial intensity is maintained at 30 kt for this advisory. Gradual weakening is expected over the next day or so as Hilda moves over even cooler waters and into a drier, more stable environment. These conditions should suppress new convective development, as suggested by the latest GFS and ECMWF model simulated satellite imagery. Thus, the latest NHC official forecast shows Hilda degenerating into a remnant low on Friday. Thereafter, the weakening remnant low is forecast to open up into a trough on Saturday, well east of the Hawaiian Islands. Hilda is moving northwestward or 305/11 kt. The cyclone is expected to turn more west-northwestward overnight and maintain this heading through dissipation as it moves along the southern periphery of a low-level ridge to its north. The track models are still tightly clustered, and the official NHC forecast has only been adjusted to reflect the slower forward speed noted in the latest guidance.
