...LESLIE DEGENERATES INTO A TROUGH...
...THIS IS THE LAST NHC ADVISORY...
SUMMARY OF 300 PM GMT...1500 UTC...INFORMATION
----------------------------------------------
LOCATION...33.3N 43.4W
ABOUT 975 MI...1570 KM WSW OF THE AZORES
MAXIMUM SUSTAINED WINDS...50 MPH...85 KM/H
PRESENT MOVEMENT...NE OR 50 DEGREES AT 31 MPH...50 KM/H
MINIMUM CENTRAL PRESSURE...1000 MB...29.53 INCHES
WATCHES AND WARNINGS
--------------------
There are no coastal watches or warnings in effect.
DISCUSSION AND OUTLOOK
----------------------
At 300 PM GMT (1500 UTC), the remnants of Leslie were located near
latitude 33.3 North, longitude 43.4 West. The remnants are moving
quickly toward the northeast near 31 mph (50 km/h). A gradual turn
toward the east at a fast forward speed is expected starting
tonight, with a continued eastward motion expected into early next
week. The remnants of Leslie are expected to move over or very near
the Azores Sunday and early Monday.
Recent satellite-derived wind data indicate that Leslie has
degenerated into a trough, but maximum sustained winds remain near
50 mph (85 km/h) with higher gusts. The remnants of Leslie are
expected to gradually weaken during the next couple of days.
Tropical-storm-force winds extend outward up to 140 miles (220 km)
from the center.
The estimated minimum central pressure is 1000 mb (29.53 inches).
HAZARDS AFFECTING LAND
----------------------
None.

ASCAT-B data valid near 1300 UTC indicated that Leslie's fast
forward motion has caused it to open into a trough. Therefore, this
will be the last NHC advisory on Leslie. The ASCAT data indicated
that winds of 40-45 kt are still present on the east side of
Leslie's remnants, where it continues to produce limited deep
convection.
A mid-latitude frontal system is nearing the remnants of Leslie, and
the two systems are expected to merge within the next 12 h or so,
marking Leslie's full transition to a post-tropical cyclone. It is
possible that Leslie will redevelop a closed circulation as a
non-tropical low at that point. The cyclone is expected to turn
eastward on Sunday, bringing it very near or over the Azores late
Sunday and through early Monday. By Monday afternoon, Leslie's
center is expected to become poorly defined again as it interacts
with another weaker mid-latitude cyclone to the east of the Azores.
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
