Hi everyone.  I am VERY sorry to say that the weather is choosing not to agree with us for our wetland trip tomorrow.  We have confirmed with Kananaskis as well that we can rebook for the alternate date of June 15th.  Let's all cross our fingers for a sunny clear day instead.

Attached is the actual weather warning in effect so that you can understand our reason for cancelling.  Volunteers - I am so SORRY!  I hope that you can make it work to join us on the 15th instead.  If not, please let me know as soon as possible.

Thank you to everyone for your flexibility.

Special weather statement in effect for:
  • Kananaskis Improvement District near Highwood House
  • Kananaskis Improvement District near Kananaskis Village
  • M.D. of Bighorn near Canmore Exshaw and Ghost Lake
  • M.D. of Bighorn near Ghost River Wilderness
An abrupt change in the weather is coming to most of Alberta tonight into Wednesday.

A strong low pressure system is forecast to develop by this evening west of Edmonton near the BC border. This low will then move east-southeast through the province. As it does so, a big change in the weather will occur.

An area of rain will move into west-central parts of the province on Tuesday night, into the Capital Region by Wednesday morning, and to the Saskatchewan border byWednesday evening. The heaviest rain will extend from Hinton and Grande Prairie eastward to Edmonton, Cold Lake and Lloydminster. Current indications are that rainfall amounts will be in the 30 to 40 mm range, but some areas of 50 to 75 mm are possible, especially with any thunderstorms embedded in the rain.

In addition, higher elevations of the foothills and mountain parks to the west of Edmonton and Calgary may see the precipitation change over to snow late Wednesdayovernight. Current indications are that some parts of these regions may receive 5 to 10 of snow by Wednesday morning.

Finally, this system will bring strong winds to much of the province. Beginning Wednesday afternoon much of east-central Alberta will likely see northerly winds with gusts up to 100 km/h.
