Flood Warnings and Advisories

Northeast Region – High Streamflow Advisory (ISSUED) – North Rockies, Liard, Peace, Upper Fraser - High Streamflow Advisory (MAINTAINED) – Cottonwood River, Quesnel River, Horsefly River, Bowron River
ISSUED: 1:30PM June 14, 2020

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

  • Peace Region, including the Kiskatinaw River, Halfway River and tributaries around Fort St. John and Dawson Creek
  • North Rockies including the Muskwa River, Sikanni Chief River, Fontas River and tributaries west of Fort Nelson
  • Liard River and tributaries
  • Upper Fraser River at Prince George and upstream

The River Forecast Centre is maintaining, a High Streamflow Advisory for:

  • Cottonwood River
  • Quesnel River
  • Horsefly River
  • Bowron River

Wet weather has been prevailing over the region, with 10-45 mm of rainfall being observed over the last 48 hours across most of the region. Environment and Climate Change Canada has issued rainfall warnings for the northern Rockies, with 50-90 mm of total precipitation expected by later Monday. In the Robson Valley and Cariboo Mountains, lesser amounts of rain are expected.
In the north-east (Liard, Northern Rockies, Peace), rapid rises in river levels are expected Sunday and Monday, and potential extend into Tuesday for larger river systems. Flows in these regions are expected to reach 2-year to 5-year return period levels, with the potential for localized low-lying flood issues, particularly on smaller tributary systems. In the Cariboo Mountains and Upper Fraser tributaries, flows are also expected to see rises on Sunday and Monday, but are generally expected to remain below high flow levels already experienced earlier this year.

The public is advised to stay clear of the fast-flowing rivers and potentially unstable riverbanks during the high-streamflow period.

The River Forecast Centre continues to monitor the situation and provides updates as conditions warrant.
