The west coast of British Columbia is bracing for significant weather changes as an atmospheric river approaches. Expected to commence within the next 48 hours, this event could bring heavy rainfall and snowfall to various areas.
Heavy Rain and Snowfall Forecasted
The atmospheric river, categorized as a Level 3 event, is anticipated to deliver up to 200 mm of rain in certain regions, particularly around Tofino and Abbotsford. In areas near Vancouver, rainfall could reach between 50 to 75 mm, while higher elevations such as Whistler may see nearly 100 mm of precipitation.
Key Forecast Details
- Rain: Expected rainfall up to 200 mm in specific areas.
- Snow: Mountain regions could receive 40 to 60 cm of snow.
- Peak Rainfall: Heaviest rainfall likely on Monday.
This intense weather event presents both advantages and challenges. For ski enthusiasts, the snowfall brings much-needed precipitation after a slow start to the season. Ski resorts have experienced delays in openings, making this forecast a welcome change. However, travel conditions to these resorts may become hazardous.
Impact of Atmospheric Rivers
Atmospheric rivers, similar to hurricanes in categorization, are classified based on the expected volume of rainfall and duration. This particular event is a Level 3 on a scale of 5 for Vancouver Island and a Level 4 just south on the U.S. west coast.
Weather Risks and Benefits
While substantial rainfall can be beneficial for areas facing drought, it also poses risks. Patrick Duplessis, a meteorologist, highlights that the prolonged precipitation could lead to challenges over the next 72 hours.
Residents and travelers in British Columbia should prepare for the upcoming weather changes and stay informed about conditions as this atmospheric river unfolds.
