UPGRADED: November 22, 2017 9:45 PM
The River Forecast Centre is upgrading to a Flood Watch for:
A series of storm systems is passing over coastal British Columbia, bringing extended period of rain and warm temperatures. Rainfall totals through Wednesday were in the 30-60mm range through the region. Snow melt is also contributing to streamflow runoff. Rainfall rates in the region are still relatively high, with 3-5mm/hour being observed at the Nostetuko Snow Weather Station.
The river level on the Kingcome River has been rising rapidly through the day. The gauge at the Gwa-Yee Village is currently at 3.73 m, and rising at approximately 15-20 cm/hour. Similarly, the Water Survey of Canada gauge (08GF009) is currently at 6.47 m and rising at 20 cm/hour. Additional rises in river levels up to 1.0-1.5 m are possible overnight into Thursday.
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.
