Officials have upgraded the Boundary region to a full flood warning.
In an update at noon Thursday (May 4), the River Forecast Centre said that rivers are expected to keep rising due to snowmelt runoff until Friday, before moderate to heavy rainfall is expected, creating significant flood hazards.
Currently the Granby River is currently flowing in the two-to-five-year flow range, but this could rise to levels that reflect a 10-year to 20-year flow.
Severe flooding that would be comparable to the devastating 2018 floods “may be possible in areas that receive high rainfall amounts,” the centre said.
Peak river levels are expected on Saturday through Monday.
A local state of emergency has been activated for rural Grand Forks, where 10 properties have been told to evacuate in Manly Meadows.
A further 34 properties are under an evacuation alert.

In a statement Wednesday afternoon, Grand Forks city officials said they continue to monitor river levels and urged everyone to exercise extreme caution.
“Please obey signs and barricades blocking off trails due to fast-moving water or potential flooding areas, notably the Black Train Bridge, so that the work crews can continue the safe construction of Tiger Dams behind Roxul, South Ruckle,” the statement read.
Sand piles and bags have been restocked at the following locations for public use:

As we approach the 5-year anniversary of the devastating 2018 #BCfloods in Grand Forks, officials have upgraded the Boundary region 'watch' to a full warning. Basically, flooding is imminent.

On May 10, 2018, after a week of high temperatures and three days of rainfall Grand Forks and the Boundary Region experienced the worst flood in history, as the confluence of the Kettle and Granby Rivers exceeded a 200 year flood level.
More to come.
