Post-Tropical Cyclone Bill Discussion Number   7
NWS National Hurricane Center Miami FL       AL022021
1100 PM AST Tue Jun 15 2021

Satellite imagery indicates that Bill has become extratropical over 
the north Atlantic. A partial scatterometer overpass showed 35-40 
kt winds to the east-southeast of the center, so the initial 
intensity is lowered to a possibly generous 45 kt.  The 
extratropical low should continue to weaken and move quickly toward 
the northeast until it weakens to a trough between 12-24 h.

This is the last advisory on Bill by the National Hurricane Center.
