Post-Tropical Cyclone Madeline Discussion Number 13
NWS National Hurricane Center Miami FL EP142022
300 PM MDT Tue Sep 20 2022
Madeline has lacked organized deep convection for about 16 hours and
it is unlikely to redevelop any in the future. Therefore, the
system has become a post-tropical remnant low and this will be the
final NHC advisory on Madeline. A recent scatterometer overpass
supports maintaining the initial intensity at 30 kt for this
advisory. The remnant low should gradually spin down over the next
few days and is expected to open up into a trough by the end of the
forecast period.
The depression is moving just north of west at 280/5 kt. This
general motion is expected to continue with a gradual turn to the
west-southwest moving with the low-level steering flow. The NHC
track forecast remains close to the multi-model consensus aids.
This is the final NHC advisory for Madeline. For additional
information on the remnant, please see High Seas Forecasts issued by
the National Weather Service, under AWIPS header NFDHSFEPI, WMO
header FZPN02 KWBC, and on the web at
