2. PUBLIC WEATHER IMPACTS AND WARNINGS SUMMARY.  
 
DISCUSSION: THIS STORM IS EXPECTED TO BEHAVE MORE LIKE A STRONG FALL  
STORM WITH NORTHERLY WINDS AND HEAVY RAIN. A COLD FRONT MOVING OVER  
NEWFOUNDLAND ON SUNDAY WILL INTERACT WITH ODETTE'S MOISTURE TO  
ENHANCE THE RAINFALL OVER SOUTHEASTERN NEWFOUNDLAND LATE IN THE DAY  
SUNDAY AND SUNDAY NIGHT. A SPECIAL WEATHER STATEMENT IS IN EFFECT  
FOR EASTERN NEWFOUNDLAND FOR SUNDAY INTO MONDAY.  
 
THERE WILL BE SOME MINOR INFLUENCE IN NOVA SCOTIA'S WEATHER WITH  
GUSTY NORTHERLY WINDS ON SUNDAY. GUSTS COULD BE UP TO 70 KM/H IN  
CAPE BRETON WHICH MAY CAUSE SOME MINOR ISSUES. SOME ENHANCED  
RAINFALL IS LIKELY OVER EASTERN NOVA SCOTIA SUNDAY MORNING AS ODETTE  
INTERACTS WITH THE COLD FRONT.  
 
A. WIND.  
 
FOR NEWFOUNDLAND, STRONG NORTHERLY WINDS GUSTING 80 TO 100 KM/H ARE  
LIKELY WITH POSSIBLY HIGHER COASTAL GUSTS. THIS COULD HAVE SOME  
IMPACTS ON TREES AND COULD LEAD TO SOME POWER INTERRUPTIONS.  
 
B. RAINFALL.  
 
50 TO 80 MM IS FORECAST WITH THE POSSIBILITY OF 100 MM FROM SUNDAY  
THROUGH MONDAY MORNING. IF THE HIGHER AMOUNTS MATERIALIZE, SOME  
LOCAL FLASH-TYPE FLOODING MAY OCCUR IN PRONE AREAS.  
 
C. SURGE/WAVES.  
 
WAVES 2 TO 3 METRES CAN BE EXPECTED ALONG THE ATLANTIC COAST OF NOVA  
SCOTIA STARTING SUNDAY MORNING, THEN GRADUALLY SUBSIDING SUNDAY  
NIGHT.  
 
HEAVY WAVE ACTION ACCOMPANYING THE WINDS CAN BE EXPECTED ALONG  
NORTH-FACING COASTS IN EASTERN NEWFOUNDLAND. WAVES 2 TO 3 METRES  
WILL REACH THE SOUTH COAST OF NEWFOUNDLAND SUNDAY EVENING. WAVES 3  
TO 5 METRES CAN BE EXPECTED ALONG EAST COAST OF THE AVALON PENINSULA  
OVERNIGHT SUNDAY NIGHT AND DURING THE DAY MONDAY. THESE WAVES ARE  
EXPECTED TO GRADUALLY SUBSIDE MONDAY NIGHT.  
 
STORM SURGE IS NOT EXPECTED TO BE SEVERE WITH ODETTE.  
 
3. MARINE WEATHER IMPACTS AND WARNINGS SUMMARY.  
 
GALE TO STORM-FORCE WINDS ARE EXPECTED OVER MANY OFFSHORE MARINE  
AREAS INCLUDING THE GRAND BANKS AND SLOPE WATERS SOUTH OF THE
