Flood Warnings and Advisories

High Streamflow Advisory – North Coast
ISSUED: October 23, 2017 10:30 AM

The River Forecast Centre is issuing the High Streamflow Advisories for:

  • North Coast including streams and rivers in the Kitimat, Terrace and surrounding areas

An intense frontal system is expected to pass over the North Coast over the next two days. Environment Canada has issued a rainfall warning for the region. Rainfall is expected to be heavy on Monday, and potentially stall over the region on Tuesday, continuing to deliver heavy precipitation. Precipitation totals in the 110-150 mm, or more, range are possible through Tuesday, with the heaviest amounts currently forecasted around the Kitimat and Terrace area. Adjacent areas may also see heavy rainfall, particularly if there are any shifts in the forecasted track of the front.


River levels are expected to respond to this rainfall, with rapid rises expected through Monday and Tuesday.


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


 A High Streamflow Advisory means that river levels are rising or expected to rise rapidly, but that no major flooding is expected.  Minor flooding in low-lying areas is possible.
 A Flood Watch means that river levels are rising and will approach or may exceed bankfull.  Flooding of areas adjacent to affected rivers may occur.
 A Flood Warning means that river levels have exceeded bankfull or will exceed bankfull imminently, and that flooding of areas adjacent to the rivers affected will result.
