Tropical Depression LEE (Text)

Tropical Depression Lee Discussion Number  14
NWS National Hurricane Center Miami FL       AL142017
500 AM AST Mon Sep 18 2017

Lee's cloud pattern has deteriorated considerably this morning.
All that remains of the deep convection are a few fragmented bands
in the northeast quadrant.  The initial intensity is generously
held at 30 kt for this advisory.  Deep-layer shear is expected to
increase during the next 12 to 24 hours, and this inhibiting
factor should prevent the cyclone from maintaining what is left
of the deep convection.  Consequently, Lee should degenerate into a
remnant low by tonight.

The initial motion is estimated to be west-northwestward or 290/11
kt.  A west-northwestward to northwestward motion is expected
through the entire forecast period, or until the cyclone dissipates
in 3 days or earlier.  No significant changes were made to the NHC
track from previous advisory and the official forecast is based
mainly on the HFIP Corrected Consensus technique.
