3. TECHNICAL DISCUSSION

A. ANALYSIS

IRENE CONTINUES TO MOVE UP ALONG THE COAST OF THE AMERICAN
SEABOARD AND IS CURRENTLY PASSING JUST EAST OF DELAWARE.
RADAR DEPICTION FROM THE NORTHEASTERN UNITED STATES HAS
DEGRADED OVER THE PAST NUMBER OF HOURS AND CENTRAL PRESSURE IS
SLOWLY RISING, NOW UP TO 954 MB. SATELLITE APPEARANCE HAS
CHANGED LITTLE OVER THE PAST 4 TO 6 HOURS THUS MAINTAINING OUR 
CURRENT INTENSITY OF 70 KNOTS.


B. PROGNOSTIC

IRENE WILL CONTINUE MOVING NORTH NORTHEASTWARD FOR TODAY AND TONIGHT 
THEN GRADUALLY TURN MORE EAST NORTHEASTWARD MONDAY AFTERNOON. THE 
STORM WILL BE MOVING OVER PROGRESSIVELY COOLER WATER WITH AN
INCREASE IN SHEAR. THESE FACTORS SHOULD LEAD TO STEADY
WEAKENING AND TRANSITIONING OF IRENE INTO A POST-TROPICAL SYSTEM 
SOMETIME MONDAY MORNING. IRENE IS FORECAST TO BE BELOW HURRICANE 
STRENGTH BEFORE ENTERING CANADIAN TERRITORY. HOWEVER, HURRICANE
FORCE GUSTS OVER LAND MAY EXIST WITH THE STORM EVEN AS IT BECOMES 
POST-TROPICAL.

THE IMPACTS OF IRENE AS IT APPROACHES CANADIAN TERRITORY WILL
INCLUDE HEAVIEST RAINFALL LEFT OF TRACK AND GUSTY WINDS RIGHT OF 
TRACK. DUE TO SPRING TIDES, HEAVY POUNDING SURF AND STORM SURGE, 
THERE MAY BE SOME COASTAL IMPACTS ALONG SHORELINES RIGHT OF IRENE'S 
TRACK.

THERE IS STILL A POSSIBILITY THAT IF IRENE GETS HEAVILY SHEARED WITH 
THE LOW LEVEL CIRCULATION BEING DISPLACED FROM THE DEEPER CLOUD, THE 
FORECAST TRACK MAY SHIFT EASTWARD.
