5. TECHNICAL DISCUSSION

A. ANALYSIS

IRENE HAS ACCELERATED TOWARDS THE EAST NORTHEAST AND IS NOW MOVING
AT ABOUT 25 KNOTS. IRENE IS STARTING TO INTERACT WITH THE FRONT TO 
THE NORTHWEST. HOWEVER LATEST SATELLITE IMAGERY SHOWS A COOLING OF 
THE CLOUD TOPS NEAR THE CENTRE. INITIALIZED IRENE AS A TROPICAL
STORM BUT IT SHOULD BECOME POST-TROPICAL WITHIN THE NEXT 12 HOURS. 
WIND RADII HAVE BEEN SHRUNK BASED ON QUIKSCAT DATA.


B. PROGNOSTIC
IRENE IS MOVING OVER COOLER SST'S AND SHOULD BEGIN TO WEAKEN AS THE 
EXTRA-TROPICAL LOW TO THE NORTH BECOMES THE DOMINANT FEATURE. IRENE 
WILL THEN BECOME ABSORBED INTO THE EXTRA-TROPICAL LOW. TIMING OF THIS 
IS UNCERTAIN BUT CERTAINLY BY FRIDAY AFTERNOON.


C. PUBLIC WEATHER

NO EFFECTS ON PUBLIC WEATHER.
