Remnants Of Simon Discussion Number  38
NWS National Hurricane Center Miami FL       EP202026
200 PM MST Fri Oct 16 2026
 
Convection associated with Simon has rapidly diminished today. A 
recent scatterometer pass indicated that Simon no longer has a 
well-defined low-level center, and as a result, no longer meets the 
criteria for classification as a tropical cyclone. Therefore, this 
will be the final NHC advisory on Simon. The initial intensity is 
estimated at 30 kt.
 
The remnants are expected to move northwestward today, steered by 
the low- and mid-level flow between a trough to the west and a 
mid-level ridge to the northeast. This motion should keep the 
remnants moving parallel to the coast of Baja California Sur. 
Dissipation is expected by late tonight or early tomorrow morning.
 
For additional information on the remnants of Simon please see High 
Seas Forecasts issued by the National Weather Service, under AWIPS 
header NFDHSFEPI, WMO header FZPN01 KWBC, and on the web at
