motion is expected to continue for the next couple of days.
 
Maximum sustained winds are near 50 mph (85 km/h) with higher gusts.
Although Norman is becoming post-tropical, little change in
intensity is expected over the next couple of days. 
 
Tropical-storm-force winds extend outward up to 140 miles (220 km)
from the center.
 
The estimated minimum central pressure is 1000 mb (29.53 inches).

Norman is quickly losing the characteristics of a tropical cyclone 
as strong vertical wind shear is taking its toll. The low-level 
circulation center (LLCC) has been exposed for the better part of a 
day now, with sporadic deep convection in the northern semicircle 
remaining well removed from the center. Visible satellite imagery 
shows the LLCC becoming increasingly elongated, now marked by a 90
nm X 30 nm wide clear area. Intensity estimates support lowering the
initial intensity to 45 kt for this advisory as Norman continues to
spin down.

The track forecast takes Norman generally toward the north through 
day 3 before briefly turning it northwestward before dissipation on 
day 5, in line with GFEX. It appears that Norman will still produce 
at least gale force winds for the next couple of days as it 
interacts with a developing cold-core low to its northwest, with
GFS indicating winds in excess of 50 kt in 24-36 hours. While this
seems a little extreme, the official intensity forecast indicates
little change in intensity through day 2, with gradual weakening
thereafter.

This will be the last advisory issued by CPHC on this system.
