WATCHES AND WARNINGS
--------------------
There are no coastal watches or warnings in effect.
 
 
DISCUSSION AND OUTLOOK
----------------------
At 500 PM AST (2100 UTC), the center of Post-Tropical Cyclone 
Franklin was located near latitude 39.5 North, longitude 53.8 West. 
The post-tropical cyclone is moving toward the northeast near 17 mph 
(28 km/h). A faster northeastward motion is expected during the 
next couple of days, followed by a turn to the east-northeast. 
 
Maximum sustained winds are near 80 mph (130 km/h) with higher 
gusts. Little change in strength is expected through tonight, but 
gradual weakening is forecast this weekend into early next week.
 
Hurricane-force winds extend outward up to 60 miles (95 km) from the
center and tropical-storm-force winds extend outward up to 255 miles
(405 km).
 
The estimated minimum central pressure is 979 mb (28.91 inches).

Post-Tropical Cyclone Franklin Discussion Number  49

The satellite appearance of Franklin suggests the cyclone has 
undergone a warm core seclusion process. Earlier scatterometer data 
showed a cold front nearing the core of Franklin, and recent visible 
satellite images suggest the presence of a bent-back occlusion 
wrapping around the western side of the low that appears to be the 
focus for the ongoing convection. Also, the latest FSU phase space 
diagrams from the GFS and ECMWF models show a thickness asymmetry 
consistent with a warm-core frontal cyclone. Therefore, it appears 
Franklin has completed its extratropical transition and is no longer 
a tropical cyclone. Since the earlier scatterometer data, the latest 
global model fields suggest that baroclinic forcing has resulted in 
a deepening of the low, with an acceleration of northerly winds to 
the west of the bent-back front. A blend of wind speeds from the 
various global models supports an initial intensity of 70 kt.

Franklin appears likely to remain a powerful, hurricane-force 
extratropical cyclone during the next 12 h or so due to baroclinic 
forcing. Thereafter, the extratropical cyclone is forecast to weaken 
as the low moves deeper into the mid-latitudes and gradually fills. 
Franklin is still moving northeastward (50/15 kt) within the flow 
between a deep-layer trough over the northwestern Atlantic and a 
subtropical ridge over the central Atlantic. A faster northeastward 
motion is forecast during the next couple of days, followed by a 
gradual turn toward the east and east-southeast later in the 
period as the cyclone rotates around a larger cut-off low over the 
eastern Atlantic. The global models are finally in better agreement 
on this outcome, and the track forecast has been adjusted south of 
the previous one at days 3-5. 

This is the last advisory issued by the National Hurricane Center on 
Franklin. Additional information on this system can be found in High 
Seas Forecasts issued by the National Weather Service, under AWIPS 
header NFDHSFAT1, WMO header FZNT01 KWBC, and online at
