 TROPICAL STORM SEYMOUR DISCUSSION NUMBER  19
 NWS NATIONAL HURRICANE CENTER MIAMI FL       EP202016
 200 PM PDT THU OCT 27 2016
 
 A combination of cold sea surface temperatures and 35 kt of
 southwesterly shear has reduced Seymour to an almost convection-less
 swirl of clouds.  The initial intensity is reduced to 55 kt based
 on a blend of satellite intensity estimates, and this could be
 generous.  Rapid weakening should continue, and Seymour is forecast
 to become a remnant low in 24 hours or less, and dissipate
 completely between 48-72 hours.
 
 The initial motion is 345/10.  Seymour is forecast to turn northward
 during the next several hours, and then northeastward tonight
 or on Friday ahead of a large deep-layer trough located well
 offshore of the west coast of the United States.  The new track
 forecast is a little to the left and a little faster than the
 previous track, and it remains near the center of the guidance
 envelope.
