IN FACT...THERE HAS BEEN NO CENTRAL CONVECTION ASSOCIATED WITH FRED SINCE ABOUT 0000 UTC....AND FRED IS NO LONGER CLASSIFIABLE USING THE DVORAK TECHNIQUE. THE LACK OF DEEP CONVECTION ALSO MEANS THAT FRED IS NO LONGER A TROPICAL CYCLONE... AND IS NOW DECLARED A REMNANT LOW. THE INITIAL INTENSITY IS LOWERED TO 30 KT...BASED UPON AN EARLIER QUIKSCAT PASS AND THE ASSUMPTION THAT THERE HAS BEEN ADDITIONAL WEAKENING SINCE THAT TIME. WHAT REMAINS OF FRED SHOULD BEGIN MOVING NORTHWESTWARD TO WEST- NORTHWESTWARD WITH AN INCREASE IN FORWARD SPEED OVER THE NEXT 12 TO 24 HOURS...AS A LOW- TO MID-LEVEL RIDGE BUILDS TO ITS NORTH. SEVERAL GLOBAL MODELS STILL MAINTAIN THE REMNANTS OF FRED DURING THE FORECAST PERIOD. HOWEVER...A RATHER HOSTILE ENVIRONMENT ALONG THE FORECAST TRACK SHOULD MAKE REGENERATION A SLIM POSSIBILITY. THIS IS THE LAST NHC ADVISORY ON FRED.
