The B.C. River Forecast Centre has upgraded some flood advisories to flood watches after a trough dumped heavy rain over the region this weekend.
A watch was issued for the Moberly River near Fort Saint John, as well as the Pine River and other tributaries of the Peace River.
Water levels were already elevated in the area due to last week's rainfall, and warmer temperatures have contributed to rapidly melting snow.
The region also received an estimated 25 mm of rain over the weekend, with another 25 mm possible in the North Peace area.
Flood watches are a step up from advisories and mean river levels are approaching and could breach the banks.
Last week, several homes in the Interior were evacuated due to flooding.
A slow-moving low pressure system brought significant amounts of rain to already swollen rivers.
On Wednesday, the flood situation forced officials to order the evacuation of seven homes in the village of Burns Lake, while another home on the Cottonwood River near Prince George was destroyed on Tuesday.
April's cool weather likely increased snowpacks and delayed the spring melt, but recent warm, wet weather has caused rivers to start rising.
