The post-tropical cyclone is moving toward the north-northwest near
10 mph (17 km/h), and this general direction of motion with a
gradual decrease in forward speed is expected over the next couple
of days.

Maximum sustained winds remain near 40 mph (65 km/h) with higher
gusts. Slow weakening is forecast during the next 48 hours.

Tropical-storm-force winds extend outward up to 80 miles (130 km)

Post-Tropical Cyclone Kenneth Discussion Number  22
NWS National Hurricane Center Miami FL       EP132017
200 PM PDT Wed Aug 23 2017

Kenneth's organized deep convection has been gone for over 12 hours
now.  Satellite images also suggest it is losing its tropical
character, with some possible frontal structures developing near
and northeast of the center.  Thus, it no longer meets the
requirements of a tropical cyclone, and this is the final advisory.
The wind speed is held at 35 kt owing to the tight low-level
circulation seen on visible imagery. The post-tropical cyclone
should gradually spin down over cold waters and generally move
north-northwestward with some decrease in forward speed over the
next couple of days.  Later in the forecast period, when the cyclone
is likely to be very weak and shallow, a turn toward the northwest
is expected following the low-level flow. The official track
forecast is very close to the previous one.
