Warnings

3:51 PM NST Wednesday 05 December 2018 Winter storm warning in effect for:

  • Avalon Peninsula North

  • Avalon Peninsula Southeast

  • Avalon Peninsula Southwest

  • St. John's and vicinity

Hazardous winter conditions are expected.

Snow will begin over the Avalon Peninsula Thursday afternoon and become heavy at times in the evening, with snowfall accumulations possibly exceeding 20 cm before morning. Strengthening northeasterly winds will combine with the fresh snowfall to give reduced visibilities in blowing snow beginning Thursday evening. The heaviest snow should ease off overnight and conditions are expected to continue to gradually improve through the day on Friday, although blowing snow may continue into Friday morning as this system passes.

Consider postponing non-essential travel until conditions improve. Surfaces such as highways, roads, walkways and parking lots may become difficult to navigate due to accumulating snow.

Winter storm warnings are issued when multiple types of severe winter weather are expected to occur together.
