Tropical Storm EMILY


ZCZC MIATCDAT5 ALL
TTAA00 KNHC DDHHMM
 
TROPICAL STORM EMILY DISCUSSION NUMBER   9
NWS NATIONAL HURRICANE CENTER MIAMI FL       AL052011
500 PM EDT WED AUG 03 2011
 
SOME DEEP CONVECTION RE-DEVELOPED NEAR THE CENTER THIS AFTERNOON...
AND DATA FROM THE AIR FORCE RECONNAISSANCE PLANE CURRENTLY IN EMILY
INDICATE THAT THE INITIAL INTENSITY REMAINS 45 KNOTS...WITH A
MINIMUM PRESSURE OF 1003 MB.  WIND SHEAR IS STILL AFFECTING THE
CYCLONE...BUT GLOBAL MODELS AS WELL AS THE SHIPS GUIDANCE INDICATE
THAT THE UPPER-LEVEL ENVIRONMENT SHOULD BECOME MORE CONDUCIVE FOR
STRENGTHENING IN ABOUT 36 HOURS. BY THEN...EMILY SHOULD BE MOVING
AWAY FROM THE INFLUENCE OF THE HIGH TERRAIN OF HISPANIOLA AND
EASTERN CUBA...AND SOME INTENSIFICATION COULD BEGIN. HOWEVER...THE
OFFICIAL FORECAST IS NOT AS AGGRESSIVE AS THE GFDL AND HWRF MODELS.
 
SATELLITE AND AIRCRAFT FIXES INDICATE THAT THE EXPECTED TURN TO THE
NORTHWEST HAS NOT MATERIALIZED YET...WITH EMILY STILL MOVING
WESTWARD OR 280 DEGREES AT 12 KNOTS. SO FAR MOST OF THE DYNAMICAL
MODELS...WITH THE EXCEPTION OF THE ECMWF...HAVE HAD A NORTHWARD
BIAS.  EVEN THE LATEST RUN OF THE GFS STILL REFORMS THE CYCLONE
NORTH OF THE HIGH TERRAIN OF EASTERN HISPANIOLA.  THE OFFICIAL
FORECAST HAS BEEN SHIFTED WESTWARD DURING THE FIRST 12 TO 24
HOURS...BRINGING EMILY OVER THE SOUTHWESTERN PENINSULA OF HAITI AND
THEN EASTERN CUBA.  AFTER THAT...THE OFFICIAL FORECAST STILL
ASSUMES THAT THE WESTERN ATLANTIC TROUGH WILL DEEPEN SUFFICIENTLY
TO TURN THE CYCLONE NORTHWESTWARD AND NORTHWARD. HOWEVER...IF THE
NORTHWARD TURN DOES NOT BEGIN SOON...THE THREAT TO THE SOUTHEASTERN
UNITED STATES WILL INCREASE.
