Severe Thunderstorm Watch
Environment Canada has issued a Severe Thunderstorm Watch for Vernon, Kelowna and Penticton.
A few thunderstorms - developing along the U-S border near noon - will move north this afternoon.
The weather office says an isolated severe thunderstorm could drop up to 20 millimetres of rain and large hail - and also create intense lightning and wind gusts up to 70-kilometres-an-hour.
Flash floods and water pooling on roads are also possible.
