TROPICAL DEPRESSION ONE SPECIAL DISCUSSION NUMBER 1
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL AL012010
600 PM EDT FRI JUN 25 2010
THE AIR FORCE RESERVE HURRICANE HUNTER AIRCRAFT INVESTIGATING THE
DISTURBANCE IN THE WESTERN CARIBBEAN SEA HAS FOUND A WELL-DEFINED
CIRCULATION CENTER WITH A MINIMUM CENTRAL PRESSURE OF AROUND 1004
MB. BASED ON DATA FROM THE AIRCRAFT...ADVISORIES ARE BEING
INITIATED ON TROPICAL DEPRESSION ONE AT THIS TIME. THE INITIAL
INTENSITY IS SET AT 30 KT BASED ON A BLEND OF WIND DATA FROM THE
AIRCRAFT AND SURROUNDING OBSERVATIONS.
THE DEPRESSION IS VERY CLOSE TO TROPICAL STORM STRENGTH...AND
CONDITIONS APPEAR FAVORABLE FOR SOME INTENSIFICATION BEFORE IT
REACHES THE YUCATAN PENINSULA IN A DAY OR SO. AFTER WEAKENING OVER
LAND...THE CYCLONE COULD REGAIN SOME STRENGTH WHEN IT ENTERS THE
SOUTHERN GULF OF MEXICO. THE OFFICIAL INTENSITY FORECAST IS CLOSE
TO THE DECAY SHIPS MODEL...WHICH INCLUDES THE EFFECTS OF
INTERACTION WITH THE YUCATAN PENINSULA.
THE INITIAL MOTION IS RATHER UNCERTAIN BUT THE BEST ESTIMATE IS
300/09. A MID-LEVEL RIDGE IS FORECAST TO PERSIST OVER THE GULF OF
MEXICO FOR THE NEXT 48 TO 72 HOURS...THEREFORE A GENERAL
WEST-NORTHWESTWARD MOTION IS EXPECTED DURING THAT TIME...WHICH
SHOULD BRING THE CYCLONE ACROSS THE YUCATAN PENINSULA AND INTO THE
SOUTHERN GULF OF MEXICO. AFTER 72 HOURS THE TRACK MODEL GUIDANCE
DIVERGES...WITH ONE GROUP...INCLUDING THE HWRF AND GFDL...TAKING
THE SYSTEM ON A MORE NORTHERLY OR NORTHEASTERLY TRACK. A SECOND
GROUP OF GUIDANCE...INCLUDING THE GFS...ECMWF AND NOGAPS KEEPS THE
SYSTEM ON A MORE WESTERLY TRACK OVER THE SOUTHERN GULF OF MEXICO.
THE OFFICIAL FORECAST IS A BLEND OF THESE TWO.
A TROPICAL STORM WARNING IS REQUIRED FOR THE EAST COAST OF THE
YUCATAN PENINSULA AT THIS TIME. IF THE CYCLONE MOVES SOUTH OF THE
OFFICIAL FORECAST TRACK...A TROPICAL STORM WARNING FOR BELIZE MAY
BE REQUIRED LATER THIS EVENING.
