A flood watch has been issued for the Lower Thompson area amid this weekend’s warm temperatures leading to faster snowmelt rates.
In an updated bulletin on Sunday morning (April 30) the River Forecast Centre said the areas of concern include Skeetchestn, Cache Creek and the surrounding area, Deadman River, Criss Creek, and the Bonaparte River.
The Nazko River and West Road River are also under a flood watch.
“A strong upper ridge that brought hot temperatures across the province is breaking down. An upper low is expected to bring unsettled weather and showers [Sunday], particularly for the South Interior,” the bulletin reads. “Another period of warmer temperatures is expected next week, with well above average temperatures expected.”

“Flows in areas around the Nazko River, West Road (Blackwater) River, Bonaparte River, Deadman River, and Criss Creek are currently in the two-year to 10-year range with additional rises forecast today and into next week; flooding is possible in these rivers and in similar ungauged rivers near to these areas.”
