Environment Canada has issued a severe thunderstorm watch for most of the greater Kawarthas region for Monday afternoon and evening (August 29).
The severe thunderstorm watch is in effect for Peterborough County, the City Kawartha Lakes, Haliburton County, and northern Hastings County.
Thunderstorms are expected to progress northeastward through Monday afternoon into the evening.
The main hazard will be strong wind gusts of 90 to 100 km/h, although hail up to nickel size is possible with the strongest storms.
A tornado also cannot be ruled out, especially over eastern Ontario.
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.
Severe thunderstorms can also produce tornadoes.
Lightning kills and injures Canadians every year. Remember, when thunder roars, go indoors!
