2:53 PM CDT Wednesday 31 July 2019 Severe thunderstorm watch in effect for areas in yellow:
Conditions are favourable for the development of dangerous thunderstorms that may be capable of producing damaging wind gusts, damaging hail and torrential rain.
A cold front tracking eastward across southern Manitoba is expected to trigger thunderstorms as it moves across the region. Some of these thunderstorms may become severe giving large hail, torrential downpours and strong winds.This watch may be extended to portions of southeastern Manitoba later this evening.
Very large hail can damage property, break windows, dent vehicles and cause serious injury. Very strong wind gusts can damage buildings, down trees and blow large vehicles off the road. Remember, severe thunderstorms can produce tornadoes. Heavy downpours can cause flash floods and water pooling on roads. Lightning kills and injures Canadians every year. Remember, when thunder roars, go indoors!
Area(s): Southern Manitoba
Timing: Late Wednesday afternoon into the evening and overnight period
Threats: 3-5 cm hail, wind gusts up to 110 km/h, rainfall accumulations in excess of 50 mm
A severe thunderstorm threat will develop over the Manitoba Parklands into the southwest corner of the province late this afternoon into the evening. Any thunderstorms that form in this region will be potentially damaging thunderstorms capable of very large hail, torrential rainfall, and strong to severe wind gusts. These thunderstorms may continue eastwards into the Red River Valley and southeastern corner of the province overnight, but there is significant uncertainty as to how far east these thunderstorms will progress. Any thunderstorms persisting into the overnight period will pose a primary hazard of large hail.
