Tropical Depression FIVE-E
ZCZC MIATCDEP5 ALL
TTAA00 KNHC DDHHMM
TROPICAL DEPRESSION FIVE-E DISCUSSION NUMBER 5
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL EP052008
200 PM PDT SUN JUL 06 2008
THE CLOUD PATTERN ASSOCIATED WITH THE DEPRESSION REMAINS RAGGED-
LOOKING AND LACKING IN BANDING FEATURES. DVORAK INTENSITY
ESTIMATES REMAIN AT 30 KT AS DOES THE ADVISORY INTENSITY. STRONG
EASTERLY SHEAR CONTINUES TO IMPACT THE SYSTEM AND I HAVE BACKED OFF
FROM THE PREVIOUS INTENSITY FORECAST BECAUSE OF THE CURRENT
DISORGANIZATION OF THE SYSTEM...THE SHEARING ENVIRONMENT...AND THE
LATEST GFDL/HWRF FORECASTS THAT CALL FOR NO SIGNIFICANT
STRENGTHENING.
IT HAS BEEN A REAL CHALLENGE TO LOCATE THE CENTER EVEN WITH VISIBLE
IMAGERY. MICROWAVE IMAGES HAVE NOT BEEN MUCH HELP EITHER. RECENT
VISIBLE PICTURES SUGGEST THAT THE CENTER MAY BE SOMEWHAT TO THE
EAST OF PREVIOUS ESTIMATES BUT THIS IS NOT YET CERTAIN. HOWEVER
THE CENTER POSITION WAS PULLED BACK A LITTLE TO THE EAST ON THIS
ADVISORY. INITIAL MOTION IS A VERY UNCERTAIN 315/7. THE MID-LEVEL
RIDGE TO THE NORTH OF THE TROPICAL CYCLONE IS QUITE WEAK AT THIS
TIME. GLOBAL MODELS PREDICT THAT THE RIDGE WILL STRENGTHEN A
LITTLE OVER THE NEXT SEVERAL DAYS. THIS SHOULD CAUSE THE TROPICAL
CYCLONE'S TRACK TO GRADUALLY BEND TO THE LEFT WITH TIME OVER THE
FORECAST PERIOD. THE OFFICIAL FORECAST TRACK IS ROUGHLY IN THE
MIDDLE OF THE MODEL TRACKS THROUGH 72 HOURS AND ROUGHLY BETWEEN THE
MEDIUM AND SHALLOW BAM GUIDANCE THEREAFTER.
AS NOTED EARLIER...THE MAIN THREAT FROM THIS SYSTEM IS HEAVY
PRECIPITATION AND THE ASSOCIATED FLOODS AND MUD SLIDES OVER THE
MOUNTAINOUS TERRAIN OF MEXICO.
