A record-breaking 15 to 25 centimetres of snow fell in Calgary Tuesday, snarling the City. Help was sent from other municipalities, notably Edmonton, to assist. CBC meteorologist Christy Climenhaga said the previous record for October 2 was set in 1954 with only about five centimetres. Calgary normally has snow clearing equipment in readiness by October 15, which was thought to be lots of time for a real snowfall. But no.
