A stretch of Highway 7 near Seabird Island was closed due to a mudslide, closing the highway between Agassiz and Hope. The debris has since been cleared and the area is open, Fleming said.

Highways 7 and 3 remain the only major routes connecting the Lower Mainland to the B.C.’s Interior, although those routes could face closures at any time.

Heavy rains and snowmelt have officials keeping a close eye on rivers, particularly in the hard-hit Sumas Prairie.

Abbotsford Mayor Henry Braun said the floodgates at the Barrowtown Pump Station remain open, allowing any water from the U.S. to flow directly into the Sumas River and then the Fraser River.

Evacuation orders were issued for three properties on Tuesday, while an evacuation alert has been issued for Lower Sumas Mountain Road and Florence Drive.
