Flood Warnings and Advisories

Flood Watch – North Coast (UPGRADED)
ISSUED: October 23, 2017 4:00 PM

The River Forecast Centre is upgrading to a Flood Watch for:

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

An intense frontal system is passing over the North Coast today and tomorrow. Environment Canada has issued a rainfall warning for the region with precipitation totals in the 100-125 mm range forecast on Monday, and an additional 50-70 mm on Tuesday. The heaviest rainfall amounts are 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. Historically, rainfall amounts in this range have caused significant river responses and localized flooding.

River levels are expected to respond with rapid rises through Monday evening and throughout the day on 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.
