B.C. forecaster downgrades north coast flood risk after atmospheric river event
KITIMAT, B.C. — British Columbia’s River Forecast Centre has downgraded a flood warning for the province’s north coast after what it describes as a strong atmospheric river event this week.
A high streamflow advisory remains in effect for the region, including the Nass River and tributaries around Stewart, Terrace, Prince Rupert and Kitimat, but a notice from the centre says the heavy downpours have ended and no significant rain is expected in the coming days.
It says the highest rainfall totals ranged from 90 to 140 millimetres, and freezing levels increased during the weather system, leading to rain-on-snow conditions in mountainous areas.
The notice says snowmelt contributed to the rapid rise in rivers in the area.
