THE Lower Mainland including Metro Vancouver, Lower Fraser Valley, Howe Sound and southern sections of Sunshine Coast will receive heavy rain beginning Saturday night, according to Environment Canada.

The rainfall amounts will range from 75 to 150 mm from Saturday evening to Monday morning.

A series of moisture laden systems associated with an atmospheric river from the Pacific will begin arriving Saturday evening and bring heavy rain to the South Coast.

Meanwhile the freezing level will lift to over the mountain tops. Heavy rain in combination with the melting snow can result in high stream levels and local flooding.
