SPECIAL TROPICAL WEATHER OUTLOOK NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL 440 PM EDT TUE OCT 19 2010
FOR THE NORTH ATLANTIC...CARIBBEAN SEA AND THE GULF OF MEXICO...
OBSERVATIONS FROM AN AIR FORCE RESERVE UNIT RECONNAISSANCE AIRCRAFT INVESTIGATING THE AREA OF LOW PRESSURE...ABOUT MIDWAY BETWEEN HONDURAS AND THE CAYMAN ISLANDS...INDICATE THAT A BROAD LOW-LEVEL CIRCULATION HAS FORMED. CONDITIONS APPEAR CONDUCIVE FOR SOME DEVELOPMENT...AND ANY INCREASE IN THE ORGANIZATION OF THE ASSOCIATED SHOWERS AND THUNDERSTORMS COULD LEAD TO THE FORMATION OF A TROPICAL DEPRESSION. INTERESTS IN THE NORTHWEST CARIBBEAN SEA SHOULD MONITOR THE PROGRESS OF THIS SYSTEM. THERE IS A HIGH CHANCE...70 PERCENT...OF THIS SYSTEM BECOMING A TROPICAL CYCLONE DURING THE NEXT 48 HOURS AS IT MOVES TOWARD THE NORTH AT 5 TO 10 MPH.
ELSEWHERE...TROPICAL CYCLONE FORMATION IS NOT EXPECTED DURING THE NEXT 48 HOURS.
