 Tropical Storm Leslie Discussion Number  37
 NWS National Hurricane Center Miami FL       AL132018
 1100 AM AST Fri Oct 05 2018
 
 The structure of Leslie has changed little since the last advisory,
 with a cluster of convection just north of the low-level center and
 a second cluster well to the southeast of the center.  The initial
 intensity is held at 55 kt based mainly on continuity from earlier
 scatterometer data, but it is possible that this is a little
 generous.  It should be noted that overall, Leslie has lost some
 organization since this time yesterday due to the disappearance of
 the eye and an overall decrease in convective banding.
 
 Leslie appears to be slowing its forward speed, with the initial
 motion now 345/8.  A turn to the north and a slower forward speed
 are expected during the next 12 h, followed by a turn toward the
 east-southeast by 36 h as Leslie encounters the southern edge of the
 mid-latitude westerlies.  A general motion toward the east-southeast
 or southeast should then continue for the remainder of the forecast
 period.  As noted in the previous advisory, there has been a
 southward shift in the guidance, and the new forecast track is again
 shifted a little to the south of the previous track.  However, it
 lies to the north of the HCCA and TVCN consensus models.
 
 The forecast track takes Leslie over cooler waters around days 2-3,
 into increasing shear around days 3-4, and over warmer water with
 decreasing shear around days 4-5.  However, the structure of Leslie
 is not currently conducive for rapid changes in intensity either up
 or down.  Thus, the intensity forecast follows the trend of the
 previous forecast and the guidance in showing gradual weakening for
 48-72 h, followed by slight intensification near 96-120 h.
 
 Large swells generated by Leslie are expected to continue during the
 next few days across the southeastern coast of the United States,
 Bermuda, the Bahamas, and the Greater and Lesser Antilles.  These
 swells will also increase near the coasts of New England and
 Atlantic Canada later today.  Please consult products from your
 local weather office as these conditions could cause life-
 threatening surf and rip currents.
