000 WTPZ44 KNHC 282038 TCDEP4 Tropical Storm Narda Discussion Number 29 NWS National Hurricane Center Miami FL EP142025 200 PM PDT Sun Sep 28 2025 Narda has become practically devoid of deep convection, and what remains is not well-organized. ASCAT-B data valid at 1708 UTC revealed a swath of 30-35 kt winds to the southeast of Narda's center, and that is the basis for the 35-kt initial intensity. Simulated satellite imagery from the GFS, ECMWF and regional hurricane models indicate that Narda is unlikely to redevelop deep convection. Given its very dry environment and SSTs below 24 deg C, that forecast appears likely to verify. Narda should therefore become a post-tropical remnant low this evening. The cyclone is still forecast to drift slowly northward to north-northeastward for the next day or so, and then turn northwestward after that until it dissipates near the middle of the week. No substantial changes were made to the official forecast, except to account for the lower intensity based on the ASCAT data.
