POST-TROPICAL CYCLONE CRISTOBAL DISCUSSION NUMBER  24
NWS NATIONAL HURRICANE CENTER MIAMI FL       AL042014
1100 AM AST FRI AUG 29 2014

Cristobal has completed its transformation into an extratropical
cyclone with all of the cold cloud tops located well north and
northwest of the exposed center.  A frontal boundary has also
wrapped around the southern portion of the circulation.  A recent
ASCAT pass revealed a large area of 50-60 kt winds to the southeast
of the center. Based on these data, the initial intensity is set at
65 kt.  Although some gradual weakening is forecast during the next
day or so, the low is expected to remain a large and powerful
cyclone over the north Atlantic until it merges with another large
low near Iceland in 36 to 48 hours.

The cyclone has been moving northeast at more than 40 kt during the
past 6 to 12 hours.  However, the low is expected to slow down some
while it continues on a northeastward heading in deep layer
southwesterly flow during the next day or so.  The official track
forecast lies between the ECMWF and GFS solution and has been
coordinated with guidance from the Ocean Prediction Center.

This is the last NHC advisory on this system.  Additional
