An evacuation order has been issued for part of a hamlet near Bella Bella, B.C., as heavy rain pummels much of the province’s central and south coast.
Residents in part of Martin Valley, located in the Central Coast Regional District’s Electoral Area A, have been ordered to leave immediately.
The regional district issued a state of local emergency on Tuesday, saying “the landslide and flood hazard risk is a significant threat to the health, safety and welfare of persons.”

Martin Valley is located about 35 kilometres northeast of Bella Bella, as the crow flies.
Evacuees have been told to follow the evacuation route provided, close all doors and windows, gather family and neighbours, if possible, and take critical items such as medicine, wallets and insurance policy contacts, if immediately available.
Evacuees can request and register for support at Old Bank Inn in Ocean Falls.
An evacuation alert is also in place for a separate area of the hamlet, due to the “current flooding and potential landslide risk from Mt. Caro Marion above village of Martin Valley,” according to EmergencyInfoBC.
An evacuation alert requires affected residents to be ready to leave on short notice.

The province’s River Forecast Centre has issued a flood watch for the Central Coast, meaning river levels are rising and there could be flooding of areas near affected rivers.
“Flooding impacts are possible in low-lying areas, particularly where intense rainfall persists or multiple pulses of rainfall occur,” says the forecast centre’s bulletin.
Parts of the Central Coast are also under a rainfall warning, south of Bella Bella near Rivers Inlet, according to Environment Canada.
The agency said between 150 and 200 millimetres of precipitation is expected for coastal communities, and up to 250 mm is forecast over the mountains “except locally higher amounts approaching 300 mm.”
Rain continues on South Coast
Heavy rain also continues to fall further south.
Environment Canada says a “prolonged atmospheric river event” will bring precipitation to northern areas of Metro Vancouver and Howe Sound, the Fraser Valley, and inland and western Vancouver Island.
The agency is warning that extensive water pooling on roads is possible and there is an enhanced risk of landslides.
“The heaviest rainfall is expected Thursday night into Friday morning,” according to the warning.
Environment Canada has urged caution to drivers, noting localized flooding in some areas is likely and some roads may become impassable.
“Landslides may occur in vulnerable areas such as steep slopes, deforested areas or recent burn scars.”
High streamflow advisories, which mean river levels are rising but no major flooding is expected, have been issued for Vancouver Island, the Fraser Valley, the South Coast and North Coast, and the upper Fraser region, including the Robson Valley and tributaries near Prince George.
