Remnants Of Don Discussion Number   6
NWS National Hurricane Center Miami FL       AL052017
1100 PM AST Tue Jul 18 2017

An Air Force Reserve reconnaissance aircraft made several passes
through the system this evening and was only able to find a sharp
wind shift--but no winds with a westerly component.  Pressures have
also risen, and it appears that Don no longer has a center of
circulation.  Therefore, Don is being declared an open wave, and
this is the last advisory on this system.  Based on the aircraft
data, the wave is still producing maximum winds of 35 kt west of
the Windward Islands over the far southeastern Caribbean Sea.

The wave is moving westward at about 22 kt, and it should continue
moving quickly westward across the Caribbean Sea during the next
couple of days.  Due to the system's fast motion, as well as
unfavorable atmospheric conditions over the Caribbean Sea,
regeneration into a tropical cyclone is not expected at this time.
However, the wave is expected to continue producing gales through
early Wednesday, and then winds just below gale force for the next
couple of days.

This is the last advisory on Don, and 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 available on the Web at
