DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
Data from an Air Force Reserve reconnaissance aircraft indicate
that Don no longer has a center of circulation.  At 1100 PM AST
(0300 UTC), the remnants of Don were located near latitude 11.9
North, longitude 62.5 West.  The remnants are moving quickly toward
the west near 25 mph (41 km/h), and this motion is expected to
continue during the next couple of days.

The aircraft data indicate that maximum sustained winds are near 40
mph (65 km/h) with higher gusts.  These winds are occurring over
the waters of the far southeastern Caribbean Sea.

Tropical-storm-force winds extend outward up to 45 miles (75 km)
to the north of the center.

The estimated minimum central pressure is 1012 mb (29.89 inches).


HAZARDS AFFECTING LAND
----------------------
WIND:  Gusts to tropical storm force in squalls are still possible
across the Windward Islands overnight.

RAINFALL:  The remnants of Don are expected to produce total rain
accumulations of 3 to 6 inches, with isolated higher amounts, across
Trinidad and Tobago, the southern Windward Islands, and northeastern
Venezuela through Wednesday.  These rains could produce
life-threatening flash floods and mudslides, especially in
mountainous areas.


NEXT ADVISORY
-------------
This is the last public advisory issued by the National Hurricane
Center on this system.  Additional information on this system can be
found in High Seas Forecasts issued by the National Weather Service,

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
http://www.opc.ncep.noaa.gov/shtml/NFDHSFAT1.shtml.
