==DISCUSSION==

CONDITIONS ARE FAVOURABLE FOR THE DEVELOPMENT OF SEVERE 
THUNDERSTORMS THAT MAY BE CAPABLE OF PRODUCING STRONG WIND GUSTS, 
LARGE HAIL AND HEAVY RAIN. THERE IS ALSO A RISK OF A TORNADO.

SEVERE THUNDERSTORMS WILL DEVELOP THIS AFTERNOON AND PERSIST THROUGH 
THE EVENING.

BE PREPARED FOR SEVERE WEATHER. IF THREATENING WEATHER APPROACHES, 
TAKE COVER IN A BASEMENT OR INTERIOR ROOM. IF OUTSIDE, PROTECT 
YOURSELF FROM FLYING DEBRIS AND HAIL. WHEN THUNDER ROARS, GO 
INDOORS(EXCLAMATION MARK) LIGHTNING KILLS AND INJURES CANADIANS 
EVERY YEAR. STRONG WIND GUSTS CAN DAMAGE TREES, BUILDINGS AND 
OVERTURN VEHICLES. LARGE HAIL CAN CAUSE SIGNIFICANT DAMAGE AND 
INJURY.
