5. TECHNICAL DISCUSSION

A. ANALYSIS
FRONTOGENESIS IS CONTINUING AND BAROCLINICITY IS BECOMING
MORE APPARENT WITHIN THE REMNANTS OF KATRINA.

THE MOISTURE FIELD ASSOCIATED WITH KATRINA HAS NOT FOLLOWED THE
STANDARD CONCEPTUAL MODEL FOR EXTRATROPICAL TRANSITION...THE
MOISTURE HAS NOT WRAPPED AROUND TO THE NORTH AND WEST AS ONE WOULD 
NORMALLY EXPECT.  MOST OF THE MOISTURE AND PRECIPITATION HAS 
OUTSTRIPPED THE SURFACE LOW AND LIES TO THE NORTHEAST OF THE SYSTEM.

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.

C. PUBLIC WEATHER
ONTARIO..HEAVY RAINFALL IS EXPECTED 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 WEDNESDAY AND THURSDAY
AHEAD AND TO THE SOUTH OF THE TRACK.
SEE WARNINGS FOR FURTHER DETAILS.

D. MARINE WEATHER
STRONGEST WINDS WILL BE ON THE SOUTH SIDE OF THE TRACK.
STRONG WINDS ARE EXPECTED FOR THE LOWER GREAT LAKES TODAY.
STRONG WINDS WITH GUSTS TO GALE FORCE OVER THE ST LAWRENCE RIVER 
TODAY AND THURSDAY. GALE FORCE WINDS EXPECTED OVER GULF OF ST
LAWRENCE WATERS EARLY THURSDAY
