==DISCUSSION==  
 
A POTENTIALLY HISTORIC ICE STORM EXPECTED THIS WEEKEND. SIGNIFICANT  
POWER OUTAGES LIKELY.  
 
FOLLOWING YESTERDAY'S ICE PELLETS AND FREEZING RAIN, THE MORE  
SIGNIFICANT FREEZING RAIN EVENT IS ABOUT TO GET UNDERWAY. FREEZING  
RAIN WILL DEVELOP EARLY THIS MORNING AND MAY BE RATHER HEAVY BEFORE  
IT CHANGES TO RAIN LATER THIS MORNING OR EARLY THIS AFTERNOON.  
 
THE ICE BUILDUP WON'T LIKELY BE AS SEVERE AS EARLIER EXPECTED -  
PERHAPS UP TO 10 MM. HOWEVER, STRONG WINDS GUSTING TO 70 KM/H IN  
COMBINATION WITH THE ICE ACCUMULATION WILL LIKELY STILL RESULT IN  
MANY POWER OUTAGES DUE TO FALLEN TREES LIMBS AND POWER LINES.  
 
DANGEROUS WINTER DRIVING CONDITIONS ARE EXPECTED ON UNTREATED ROADS,  
WORSENED BY FALLEN TREE LIMBS.  
 
TRAVEL IS NOT RECOMMENDED. SURFACES SUCH AS HIGHWAYS, ROADS,  
WALKWAYS AND PARKING LOTS WILL BECOME ICY, SLIPPERY AND EXTREMELY  
HAZARDOUS. PUBLIC SAFETY CANADA ENCOURAGES EVERYONE TO MAKE AN  
EMERGENCY PLAN AND GET AN EMERGENCY KIT WITH DRINKING WATER, FOOD,  
MEDICINE, A FIRST-AID KIT AND A FLASHLIGHT.  
 
PLEASE CONTINUE TO MONITOR ALERTS AND FORECASTS ISSUED BY  
ENVIRONMENT CANADA. TO REPORT SEVERE WEATHER, SEND AN EMAIL TO
