POST-TROPICAL CYCLONE BERTHA DISCUSSION NUMBER  23
NWS NATIONAL HURRICANE CENTER MIAMI FL       AL032014
1100 AM AST WED AUG 06 2014

Satellite images indicate that Bertha has become associated with a
frontal system and has acquired extratropical characteristics. The
low-level center is devoid of deep convection and is on the cold air
side of a frontal cloud band or trough extending from Nova Scotia
southwestward to the Bahamas. In addition, there is a strong
westerly upper-level jet over the system.

The low is moving toward the northeast or 055 degrees at 27 knots
steered by the mid-latitude westerlies. Most of the global models
keep the post-tropical cyclone moving rapidly northeastward and
then eastward over the North Atlantic.

This is the last advisory issued by the NHC on Bertha. Additional
information on this system can be found in High Seas Forecasts
issued by the National Weather Service...under AWIPS
header NFDHSFAT1 and WMO header FZNT01 KWBC.
