UPDATE: Environment Canada has downgraded the rainfall warning for B.C.’s south coast late Monday and is no longer calling for "incredible" storms. Heavy rain is still expected with some areas to receive up to 50 millimetres of rain by Tuesday morning.

Environment Canada is warning West Coast residents to brace for "an incredible series of storms" that will bring an "extraordinary" amount of rain this week.

According to forecasters "an intense jet stream over the Pacific is gathering very warm moist air from southern latitudes."

The warm subtropical weather pattern will "bombard the mountains of Vancouver Island and the Lower Mainland from today through Thursday morning."

Around Metro Vancouver, residents are warned to expect prolonged rain over the next three to four days, starting with 25 mm to 100 mm of rain by Tuesday morning.

The west coast of  Vancouver Island and Howe Sound are forecast to get 100 mm to 200 mm by Tuesday morning.

Before the rain arrives, heavy winds hitting 70 to 110 km/h are also forecast for the west coast of the island, the Sunshine Coast, the Central Coast and Haida Gwaii, during the day on Monday.

The weather system is also forecast to push the freezing level up to 2,500 metres, adding snowmelt to flooding creeks and rivers in the mountains.

Residents are warned to watch out for flooding and water pooling on roads.
