Environment Canada has issued a severe thunderstorm watch for parts of Nova Scotia today.

The alert extends from Guysborough and Pictou counties all through Cape Breton.

The weather agency says the storm could bring strong wind gusts, large hail and torrential rainfall.

“Fast moving water across a road can sweep a vehicle away. Large hail can damage property and cause injury. Remember, severe thunderstorms can produce tornadoes,” reads the weather watch.

Environment Canada says if threatening weather starts, take cover immediately.

“There isn't a place outside that is safe during a thunderstorm. Stay away from all windows, skylights and doors,” says the federal agency.

“When thunder roars, go indoors.”

Environment Canada says lightning kills up to 10 people per year.

Affected areas include:

  • Antigonish County
  • Guysborough County
  • Inverness County - Mabou and north
  • Inverness County - south of Mabou
