UPGRADED: Alonsa, Manitoba Tornado Upgraded from EF-3 to the First EF-4 Tornado in Canadian History Under the New "Enhanced Fujita" Classification


Of course Canada has had many (although rare) F4 tornadoes in our history. However, Alonsa, Manitoba has now become the first ever "EF-4" tornado under the new "Enhanced Fujita" classification in Canadian history.

Our thoughts are with those affected by this tragic event.
