A long episode of rain, at times heavy, continues.

Prolonged Atmospheric River Event

Where: Fraser Valley

What and when: - Total rainfall amounts from now to Friday: 100 to 120 mm with higher amounts possible near the mountains - Another heavy rain event expected Thursday night 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.

Remarks: An atmospheric river will remain over the South Coast of B.C. through Friday bringing periods of heavy rain across the Fraser Valley. With freezing levels near 2000 to 2500 metres, snowmelt from higher elevations may increase the impacts associated with this rainfall event.

Strong southwesterly winds are also expected on Friday.

Water will likely pool on roads and in low-lying areas. Some travel delays are possible.

Rainfall warnings are issued when significant impacts are expected due to rainfall amounts.
