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.
