Severity: Moderate Urgency: Immediate

Prolonged Atmospheric River Event 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. Rain is expected to intensify again late this afternoon to Friday under the influence of of the atmospheric river. The heaviest rainfall is expected Thursday night into Friday. ### Water will likely pool on roads and in low-lying areas. Some travel delays are possible. Landslides may occur in vulnerable areas such as steep slopes, deforested areas or recent burn scars. Fast-moving and rapidly rising water can sweep vehicles away and damage infrastructure.
