Conditions are favourable for the development of severe thunderstorms that may be capable of producing large hail and heavy rain, The Weather Network is reporting.
Issuing a statement early this morning, the forecasting service says an upper low pressure system over Vancouver Island will result in a southerly flow of moist, unstable air over the southern interior today.
A few thunderstorms developing along the US border near noon will move northward during the afternoon.
There is the potential of an isolated severe thunderstorm giving rainfall amounts up to 20 mm, two cm of hail and wind gusts to 70 km/h.
Intense lightning is likely with any thunderstorm that develops. Heavy downpours can cause flash floods and water pooling on roads.
