•South Okanagan – including Penticton

Conditions are favourable for the development of severe thunderstorms that may be capable of producing large hail and heavy rain.

A line of thunderstorms will develop near noon as an upper disturbance moves over the region. The main threat will be isolated heavy downpours giving 15 to 25 mm within one hour as well as hail with diameter up to 15 mm. A watch is upgraded to a warning when severe thunderstorms are imminent.

Fast moving water across a road can sweep a vehicle away. Large hail can damage property and cause injury. Be prepared for severe weather. Take cover immediately, if threatening weather approaches. Lightning kills and injures Canadians every year. Remember, when thunder roars, go indoors!

Environment Canada meteorologists will update alerts as required. Please monitor local media or Weatheradio. To report severe weather, send an email to pacificstorm@ec.gc.ca or tweet reports to #BCStorm.
