After many Alberta communities set new low temperature records early Tuesday morning, Environment Canada once again issued frost advisories for much of the province in the afternoon.

Frost advisories also in effect for southern Saskatchewan and western Manitoba.

In these areas, temperatures are expected to drop to near or below the freezing mark and frost is possible overnight. As of 11 p.m., Calgary was not under a frost advisory but Edmonton and Medicine Hat were added at 9:34 p.m.

Rural locations are often colder at night and this is the reason the frost advisories are in effect for those areas.
