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.
