Where: Inland Vancouver Island

What and when: - Periods of heavy rain continues to Friday

Impacts: -Prolonged heavy rain on snow combined with mountain snow melt could lead to very enhanced responses in river systems and potential for flooding. -Extensive water pooling on roads and washouts may occur. -Enhanced risk of landslides due to saturation of landscapes.

Remark: An atmospheric river will remain over the South Coast of B.C. through Friday. With freezing levels near 2000 to 3000 metres, snowmelt from higher elevations may increase the impacts associated with this rainfall event.
