Post-Tropical Cyclone Narda Discussion Number  30
NWS National Hurricane Center Miami FL       EP142025
800 PM PDT Sun Sep 28 2025

Cooler waters and dry mid-level air have taken a significant toll on
Narda. The cyclone has been devoid of organized deep convection for
several hours, leaving mainly a swirl of low- to mid-level clouds.
The initial intensity is reduced to a possibly generous 30 kt. Given
the increasingly hostile environment, along with strengthening
southwesterly shear expected during the next day or so, regeneration
of organized convection is not anticipated. As a result, this will
be the final advisory on Narda, which has become a post-tropical
remnant low.

The remnant low is forecast to drift north-northeastward into
Monday, before turning back toward the northwest by Tuesday as it
becomes steered by the low-level flow. Global model guidance
indicates that the system should gradually spin down and open into a
trough of low pressure within about 4 days.

For additional information on the remnant low, please see High Seas
