5. TECHNICAL DISCUSSION

A. ANALYSIS
THE REMNANTS OF KATRINA ARE EXPECTED TO RE-INTENSIFY AS AN 
EXTRATROPICAL LOW TODAY. MEANWHILE THE MOISTURE FIELD ASSOCIATED
WITH KATRINA HAS NOT FOLLOWED THE STANDARD CONCEPTUAL MODEL FOR
EXTRATROPICAL TRANSITION...MOST OF THE MOISTURE AND PRECIPITATION
HAS OUTSTRIPPED THE SURFACE LOW AND LIES TO THE NORTHEAST OF
THE SYSTEM CENTRE.

B. PROGNOSTIC
WITH MUCH OF THE MOISTURE ASSOCIATED WITH KATRINA MOVING WELL AHEAD 
OF THE SURFACE LOW HEAVY PRECIPITATION ACCUMULATIONS WILL OCCUR
ALONG AND TO THE SOUTH OF THE PROJECTED TRACK.  AS THE CENTER
OF THE TRANSITIONING KATRINA TRACKS NORTHEASTWARD IT WILL DEEPEN 
RAPIDLY AS IT BECOMES CAUGHT UP IN THE FLOW AROUND AN UPPER LOW
OVER CENTRAL QUÉBEC. THIS SYSTEM HAS NOW LOST ITS PRIMARY TROPICAL 
SIGNATURES AND MODEL GUIDANCE HAS NOW WELL CAPTURED THE MOISTURE 
IMPACTS OF KATRINA'S REMNANTS. AS SUCH THIS WILL BE THE LAST BULLETIN 
ISSUED ON KATRINA BY THE CHC.

THE IMPACTS OF THE EXTRATROPICAL SYSTEM WILL BE COVERED BY THE
QUÉBEC AND ATLANTIC STORM PREDICTION CENTRES AS THE SYSTEM MOVES
INTO NORTHERN QUÉBEC AND LABRADOR.

C. PUBLIC WEATHER
ONTARIO..HEAVY RAINFALL FOR AREAS ALONG THE NORTH
SHORE OF THE LOWER GREAT LAKES AND THE ST LAWRENCE RIVER FROM
EASTERN LAKE ERIE TO THE QUÉBEC BORDER AS THE TROPICAL MOISTURE
FROM KATRINA'S REMNANTS MOVES AHEAD OF THE SURFACE CENTER.
QUÉBEC..HEAVY RAINFALL IS EXPECTED FOR PORTIONS OF SOUTHERN QUÉBEC 
MAINLY ALONG THE ST LAWRENCE VALLEY.
MARITIMES..SIGNIFICANT TO HEAVY RAINFALL AMOUNTS ARE ALSO
ANTICIPATED OVER NEW BRUNSWICK FOR LATE TODAY AND THURSDAY
AHEAD AND TO THE SOUTH OF THE TRACK. POTENTIAL FOR SIGNIFICANT 
RAINFALL OVER NOVA SCOTIA AND PRINCE EDWARD ISLAND.
SEE WARNINGS FOR FURTHER DETAILS.
