Tropical Storm LIDIA (Text)

ZCZC MIATCDEP2 ALL
TTAA00 KNHC DDHHMM
TROPICAL STORM LIDIA DISCUSSION NUMBER   4
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
2 AM PDT SUN SEP 18 2005

LIDIA IS NOT LOOKING VERY IMPRESSIVE AT THE MOMENT.  IN FACT...IT IS
NOT EASY TO DISTINGUISH THE TROPICAL CYCLONE FROM THE BROADER AREA
OF DISTURBED WEATHER WITHIN WHICH IT IS EMBEDDED.  AS NOTED
EARLIER...DEVELOPMENT IS POSSIBLY BEING HINDERED BY THE INFLUENCE
OF A DISTURBANCE LOCATED A COUPLE HUNDRED N MI TO THE NORTHEAST.
ONLY VERY SLOW STRENGTHENING APPEARS LIKELY IN THIS ENVIRONMENT...
AND UNLESS LIDIA STARTS BECOMING BETTER ORGANIZED SOON...SUBSEQUENT
INTENSITY FORECASTS WILL NEED TO BE REVISED DOWNWARD.

IT CONTINUES TO BE A CHALLENGE TO FIND THE CENTER...BUT BASED ON AN
EARLIER...0419Z...SSM/I OVERPASS...IT HAS BEEN RELOCATED SLIGHTLY
TO THE EAST.  ANOTHER RELOCATION MAY BE REQUIRED USING VISIBLE
IMAGES LATER TODAY.  FOR WHAT IT IS WORTH...MY CURRENT POSITION
ESTIMATE IS NOT FAR FROM WHERE SOME SMALL BURSTS OF DEEP CONVECTION
HAVE BEEN OCCURRING.  THE ESTIMATED INITIAL MOTION IS A VERY
UNCERTAIN...AND SLOW...270/2.  TRACK GUIDANCE IS HIGHLY DIVERGENT
AND IT IS NOT CERTAIN HOW MUCH STEERING EFFECT WILL BE INDUCED AS A
RESULT OF THE INTERACTION WITH THE DISTURBANCE TO THE NORTHEAST. 
AS A COMPROMISE FOR NOW...A VERY SLOW WEST-NORTHWESTWARD TRACK IS
PREDICTED.  IT MUST BE ADMITTED...HOWEVER...THAT THERE IS NOT MUCH
CONFIDENCE IN THIS FORECAST.
