Conditions are favourable for the development of severe thunderstorms this afternoon. These severe thunderstorms will have the potential to produce hail to the size of loonies, wind gusts to 100 km/h and rainfall amounts to 75 mm.
Thunderstorms over southeastern BC will cross the border this afternoon and, with daytime heating, will have the potential to become severe.
This watch may be expanded southward and eastward through the rest of the day. Thunderstorms will weaken this evening.
Fast moving water across a road can sweep a vehicle away. Large hail can damage property and cause injury. Strong wind gusts can toss loose objects, damage weak buildings, break branches off trees and overturn large vehicles. Be prepared for severe weather. Take cover immediately, if threatening weather approaches.
