Chilliwack River – High Streamflow Advisory

Fraser Valley – To no one’s surprise, with the current rainfall warning for the Fraser Valley, the river forecast centre issued a high streamflow advisory for the Chilliwack River as well as mountainous tributaries on the north side of the Fraser Valley.

A Pacific frontal system will remain stalled over the region today and tonight resulting in continued heavy rainfall for the Fraser Valley. Rainfall amounts by Friday morning will range from 40 to 60 mm except up to 70 mm near Hope. The rain will finally ease by Friday morning as the front moves out of the region.

Localized flooding in low-lying areas is possible.

FYI

Levels of Warnings/Advisories:

  1. High Streamflow Advisory: River levels are rising or expected to rise rapidly, but that no major flooding is expected. Minor flooding in low-lying areas is possible.

  3. Flood Warning: River levels have exceeded bankfull or will exceed bankfull imminently, and that flooding of areas adjacent to the rivers affected will result.
