Currently monitoring the heavy rainfall and flood situation across southwestern Alberta. Over 150 mm (that's 6 inches) of rain has already fallen in the mountains, with slightly less in the foothills as a potent storm over northwestern Montana tracks northeastward.
New YouTube video showing the raging waters threatening homes in Canmore, Alberta, today.
Even Bow Valley has been hit hard with the heavy rain with 124 mm as of last hour.
I can easily see another 25-50 mm or more of rain in areas especially to the SW of Calgary into Friday. The rain should begin to taper off Friday afternoon as the storm weakens and the easterly flow diminishes.
Major roads have been washed out, and rivers are flowing well out of their banks creating a dangerous situation, especially for areas just to the southwest and west of Calgary and into the mountains.
This storm is producing a deep, easterly flow in the atmosphere which is forcing warm, moist air into the higher elevations. As this air gets lifted it cools then condenses out as heavy rain.
The storm is tracking a little slow than what we though a couple days ago, but it looks like the track was on target along with the placement of heaviest rainfall.
I have been monitoring the Alberta Gov't site for emergency evacuations and you can follow these right here.
