ZCZC MIATCDEP2 ALL TTAA00 KNHC DDHHMM TROPICAL DEPRESSION GIL DISCUSSION NUMBER 21 NWS NATIONAL HURRICANE CENTER MIAMI FL EP072013 800 AM PDT SUN AUG 04 2013 A SMALL BAND OF CONVECTION HAS RECENTLY FORMED ON THE SOUTHWESTERN SIDE OF THE CIRCULATION OF GIL. OTHERWISE...THE DEPRESSION IS MOSTLY COMPRISED OF CONVECTIVE DEBRIS AND SOME STABLE STRATOCUMULUS CLOUDS. SATELLTE INTENSITY ESTIMATES HAVE BEEN DROPPING...AND SUPPORT MAKING THE INITIAL WIND SPEED 30 KT. THERE APPEARS TO BE ENOUGH STABLE AIR AND SHEAR NEAR GIL FOR THE NEXT COUPLE OF DAYS TO CAUSE THE CYCLONE TO DEGENERATE INTO A REMNANT LOW DURING THAT TIME. WHILE THE LGEM/SHIPS/GFDL ARE SHOWING THE CYCLONE EVENTUALLY RESTRENGTHENING IN A FEW DAYS DUE TO A LESS HOSTILE ENVIRONMENT... THERE PROBABLY WILL NOT BE MUCH LEFT OF THE SMALL CIRCULATION OF GIL BY THAT TIME. THE OFFICIAL FORECAST IS SIMILAR TO THE PREVIOUS ONE AFTER ACCOUNTING FOR THE WEAKER INITIAL WINDS. THE CURRENT MOTION APPEARS TO BE ABOUT THE SAME AS BEFORE...250/8. A LOW-LEVEL RIDGE OVER THE EASTERN PACIFIC SHOULD CONTINUE TO STEER GIL ON THIS GENERAL MOTION FOR THE NEXT FEW DAYS. THE RIDGE SHOULD FLATTEN OUT IN THE EXTENDED RANGE...PERHAPS CAUSING A MORE WESTWARD TURN. THERE HAVE NOT BEEN ANY SIGNIFICANT CHANGES TO THE GUIDANCE...AND ONLY A SMALL NORTHWARD ADJUSTMENT WAS MADE TO THE PREVIOUS NHC PREDICTION AT 96 AND 120H.
