Flood Warnings and Advisories

South-east Region - High Streamflow Advisory (MAINTAINED) – Boundary
ISSUED: 4:00 PM May 11, 2020

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

  • Boundary Region including the Kettle River, West Kettle River, Granby River and tributaries

Rainfall last week and accelerated snowmelt over the weekend have led to high streamflow through the Boundary region, including the West Kettle River, Kettle River, Granby River and tributaries.
Temperatures are expected to ease through this week. Unsettled weather patterns are expected, with the potential for showers Tuesday and into Wednesday. Precipitation totals for this event are currently in the 10-15 mm range however localized rainfall may be higher, and the exact positioning of showers is uncertain, but possible throughout the region.
Streamflow is expected to remain high through this week, with a potential for increased flows on Wednesday in response to precipitation. Flows are expected to reach around the 2-year return period level through the Kettle and Granby Rivers, and potentially higher in the West Kettle River and it’s tributaries.

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.
