Post-Tropical Cyclone Jova Discussion Number 25
NWS National Hurricane Center Miami FL EP112023
200 PM PDT Sun Sep 10 2023
Jova has been devoid of deep convection for roughly 12 hours or so.
The overall cloud pattern continues to become disheveled, as the
system gradually spins down. Given that the system has not been
producing convection for some time now, it no longer meets the
definition of a tropical cyclone. Therefore, Jova has degenerated
into a post-tropical remnant low. The initial intensity is lowered
to 30 kt for this advisory, based on a recent scatterometer pass
which is in agreement with the latest subjective and objective
satellite intensity estimates.
Jova will continue to spin down for the next couple of days as
it remains a remnant low, before opening up into a trough in about
72 h. No significant changes were made to the official forecast,
which lies near the consensus intensity aids.
Jova's initial motion is estimated to be northwestward at 5 kt, A
gradual turn toward the west and west-southwest, with an increase in
forward motion is forecast. The NHC forecast lies near the middle
of the guidance envelope, near the model consensus.
This is the last advisory on this system from the National Hurricane
Center. For additional information on the remnant low please see
