Precipitation scarcity in B.C. somewhat alleviated by drenching rains

Get ready for another stretch of soggy weather, British Columbia, as a slug of moisture arriving from the Pacific Ocean washes over the province with plenty of rain over the next couple of days.

We’re watching the potential for triple-digit rainfall totals across portions of the province.

Special weather statements and several rainfall warnings are in place.

Strong winds will continue into Sunday for the Strait of Georgia, where gusts could peak around 60 km/h. No ferry cancellations are forecast, however, given the magnitude of the wind speeds.

The region’s current atmospheric river will also bring the potential for very heavy rainfall and high-elevation snow through early this week.

Through Tuesday, most of the rain will fall Sunday into Monday. In fact, precipitation will linger through Monday afternoon for many areas, not. easing until the evening. This could potentially interfere with any outdoor Halloween plans during the evening hours. Light rain will persist into Tuesday.

Significant rain will fall during this period. Precipitation totals will vary based on terrain, but an additional 50-150 mm could fall through the first half of the work week.

Forecast models suggest this next atmospheric river will be categorized as an AR2 -- providing beneficial rain, but still worth monitoring for some localized hazards.

Lesser rainfall amounts are expected over eastern Vancouver Island, Victoria, and southwestern sections of Metro Vancouver due to rain-shadow effects.

While these waves of moisture look to bring the much needed rains to the drought-stricken regions of B.C., too much moisture in a short period of time could also bring the threat for localized flooding. Dry soils struggle to absorb moisture. Ongoing drought conditions combined with heavy rainfall could lead to more water running off than absorbing into the ground.

Droughts don’t clear up immediately either, and it often takes several systems to tip the balance towards a more traditionally wet pattern.

Freezing levels are forecast to rise up to 1800 metres for the South Coast, peaking early Monday, so expect messy travel through some of the mountain passes this weekend, as well. Most of the precipitation fails to push inland across the Interior, but dicey travel is possible across Eagle and Rogers Pass with heavy, wet snow through Wednesday.

While the month looks to end on a drier not for coastal communities, B.C. could face the prospect of another atmospheric river heading into the end of this week.
