Heavy rainfall expected in mountain parks for May long weekend
CALGARY – Attention May long weekend campers: it’s expected to rain this weekend.
Environment Canada issued a special weather statement on Friday morning, warning that a low pressure system moving into the province from B.C. will produce heavy rain throughout the foothills.
“A special weather statement is basically notice that a particular situation is being closely monitored, explains Global Calgary Meteorologist Jordan Witzel. “Right now, no rainfall warnings are in place… but I expect some will be issued for the foothills and mountain parks at some point this weekend.”
The rain is expected to begin on Saturday afternoon, and persist for much of the long weekend until tapering off on Monday evening.
It’s anticipated Calgary and the mountain parks will receive anywhere from 25-40 millimetres of rain by Monday evening.
However, some areas in the mountains may even see snow in higher elevations.
Rainfall in the area from Airdrie northwest to Grande Cache is expected to be between 30 and 75 mm, with up to 100 mm possible in some locations.
The heaviest rain is expected to fall in the Nordegg and Rocky Mountain House regions.

Airdrie – Cochrane – Olds – Sundre
Banff National Park
City of Calgary
Jasper National Park
