Flood Warnings and Advisories

High Streamflow Advisory – Peace Region, Northern Rockies
ISSUED: 1200h June 25th, 2018

The River Forecast Centre is issuing a High Streamflow Advisory for:

  • Peace Region including tributaries around Fort St. John, Dawson Creek, and areas to the west
  • Northern Rockies including tributaries around Fort Nelson and areas to the west

A low pressure system is expected to move across the BC Interior today, and stall near the north-east corner of BC. Heavy rain is expected to develop as this low tracks across the province. Environment and Climate Change Canada has issued rainfall warnings for the region, with rainfall amounts in the 60 to 80 mm range expected by Tuesday morning. Weather modelling is indicating the potential for rainfall totals to be higher than this over higher elevation terrain in the northern Rocky Mountains.


Rapid river rises are expected in response to this rainfall tonight and Tuesday, and possibly into Wednesday for larger river systems. Currently forecasted rainfall totals are in the range that have led to localized flood impacts in previous flood events (eg 2011, 2012, 2016).


The River Forecast Centre will continue to monitor conditions and update this advisory as conditions warrant.
