==DISCUSSION==
A PASSING COLD FRONT WILL COMBINE WITH AN UNSTABLE AIRMASS RESULTING
IN A FAVOURABLE ENVIRONMENT FOR THE DEVELOPMENT OF SEVERE
THUNDERSTORMS OVER SOUTHEASTERN MANITOBA.
THUNDERSTORMS ARE EXPECTED TO DEVELOP EARLY THIS AFTERNOON (1-3 PM
LOCAL TIME) AND DIMINISH THIS EVENING.
THE PRIMARY HAZARDS WITH THESE STORMS INCLUDE LARGE HAIL, STRONG
WIND GUSTS AND HEAVY RAINFALL.
HEAVY RAINFALL IS EXPECTED TO IMPACT ALREADY WATER LOGGED AREAS FROM
LAST NIGHTS STORMS. SO FURTHER FLASH FLOODING WILL ALSO BE A RISK IN
FLOOD PRONE AREAS.
FAST-MOVING AND RAPIDLY RISING WATER CAN SWEEP VEHICLES AWAY AND
DAMAGE INFRASTRUCTURE. WHEN THUNDER ROARS, GO INDOORS(EXCLAMATION
MARK) LIGHTNING KILLS AND INJURES CANADIANS EVERY YEAR. SEVERE
THUNDERSTORM WATCHES ARE ISSUED WHEN CONDITIONS ARE FAVOURABLE FOR
THE DEVELOPMENT OF THUNDERSTORMS CAPABLE OF PRODUCING DAMAGING HAIL,
WIND OR RAIN.
