PRINCE GEORGE, BC: A Flood Watch has been issued to the Peace Region including streams near Pine Pass, Chetwynd, Tumbler Ridge, Dawson Creek and Fort St. John, Details below…
The BC River Forecast Centre is issuing a Flood Watch for:
- Northeast BC including streams near Fort Nelson
Rainfall from an Alberta Low has caused rapid increases in water levels in streams overnight in the region. Rainfall totals this morning ranged from 15 to 60 mm, with higher totals recorded near Pine Pass.
Environment Canada indicates this weather system is expected to continue to affect the region through Friday. The system has evolved to include a centre of accumulation in the Peace region and a centre in the Northeast region. Forecast rainfall totals range from 50 to 100 mm over the next 48 hours (which began Wednesday morning). The higher totals are likely near Pine Pass and Hudson Hope and southeast of Fort Nelson.
Water levels in smaller streams at higher elevation have risen rapidly today and are forecast to continue rising through Thursday in the Peace region with flooding in low-lying areas. Water levels in major streams in the region are expected to continue to rise through Friday and possibly Saturday.
Based on current precipitation forecasts and streamflow conditions, flood forecast modeling indicates flooding is likely along the following streams and their smaller tributaries by Thursday and into Friday:
- Moberly River is forecast to reach flows between 100 and 120 m3/s by Thursday and peak early Friday morning. Peak flows may exceed the 10-year return period flow. Flows will begin to recede by late Friday.
- Kiskatinaw River is forecast to reach flows between 300 and 430 m3/s by Thursday and peak early Friday morning. Peak flows may exceed the 10-year return period flow. Flows will begin to recede by late Friday.
- Fontas River is forecast to reach flows between 400 to 570 m3/s by Friday and peak by Saturday morning. Peak flows may approach the 20-year return period flow event. Flows will begin to recede by late Saturday.
Other major streams in the region are expected to see high flows by Thursday, although flooding is not expected at this time. Flows will vary depending on the actual precipitation totals for a given basin.
The public is cautioned to stay clear of rivers during rain events due to quickly flowing water and potentially unstable riverbanks.
The River Forecast Centre will continue to monitor conditions and will provide updates as conditions warrant.
