Residents in the Sioux Lookout, Big Trout Lake and Kasabonika Lake areas are warned of a string of severe thunderstorms making their way through the region today.

Environment Canada says the storms are expected to produce up to 90 kilometre per hour winds with Toonie-sized hail.

Staff remind the public to always seek shelter when threatening weather approaches, and to never leave your shelter until at least 30 minutes past the last roar of thunder to ensure the system has passed your area.
