A. ANALYSIS
IGOR HAS BEEN POST-TROPICAL SINCE THIS AFTERNOON, AND SATELLITE
IMAGERY CONTINUES TO SHOW IGOR AS A LARGE AND STRONG BAROCLINIC
STORM.
B. PROGNOSTIC
POST-TROPICAL IGOR WILL CONTINUE TRACKING NORTH THEN TURN
NORTHWESTWARD ACROSS THE LABRADOR SEA AS IT BEGINS TO WEAKEN OVER
THE NEXT 36 HOURS. THE GEM-REGIONAL AND GFS MODELS SEEM TO HAVE A
VERY GOOD HANDLE ON ITS PRESSURE AND WIND PATTERNS AND THE CHC
TRACK AND INTENSITY IS VERY CLOSE TO THIS GUIDANCE.
C. PUBLIC WEATHER
SEE ABOVE.
D. MARINE WEATHER
STORM SURGE OF UP TO 85 CM WAS REPORTED ALONG PARTS OF THE NORTHEAST
COAST OF NEWFOUNDLAND TUESDAY EVENING. THIS SURGE WILL SPREAD DOWN
THE AVALON PENINSULA OVERNIGHT AND INTO EARLY WEDNESDAY MORNING.
SIGNIFICANT WAVE HEIGHTS IN EXCESS OF 10 METRES ARE EXPECTED OVER
SOME OFFSHORE WATERS IN THE WIND FLOW AND SWELLS GENEARTED BY IGOR.
WIND RADII NO LONGER GIVEN DUE TO THE POST-TROPICAL NATURE OF IGOR.
HOWEVER HURRICANE FORCE WINDS STILL EXIST NEAR THE STORM WITH
THE STRONGEST WINDS IN THE NORTHWESTERLIES TO THE WEST OF IGOR'S
CENTRE.
AS IGOR IS NOW COMPLETELY POST-TROPICAL AND BEHAVING MORE AND MORE
LIKE A BAROCLINIC SYSTEM, ITS PRESSURE AND WIND FIELDS ARE BEING
WELL HANDLED BY OUR GLOBAL MODELS. AS A RESULT IT IS EXPECTED THE
CHC WILL LIKELY CEASE MESSAGING ON IGOR LATER THIS MORNING.
