Depending on the development and track of the low, warnings may be extended into the Edmonton and surrounding areas. Note: snowfall warnings require snowfall accumulations of 10 cm in 12 hours. Since this is the first snowfall of the season, a weather warning has been issued for the first 5 cm of snow.
