Discussion:

Himawari-9 shortwave infrared satellite image (Weathernerds). Francisco is the swirl of faint low clouds north of the northern tip of Taiwan.

Francisco continues to consist of a swirl of low clouds that is not producing any significant convection, and is fully embedded in a pocket of dry air over the southern East China Sea. Given that Francisco has failed to generate any new convection for the last 18 hours or so, and scatterometer data indicates its winds have decreased below tropical storm force, Francisco is now a post-tropical remnant low. The intensity of 25 kts is based on recent ASCAT and Oceansat-3 passes that showed winds of 20 to 25 kts north of the center.

Francisco is slowing down and will likely grind to a halt just north of Taiwan. Although SSTs are quite warm, strong shear and dry air should prevent any redevelopment and the circulation should open up into a trough and dissipate within the monsoon gyre on Saturday.

This is the last advisory on Francisco.
