The rainfall in November has already hit an all-time high in Chilliwack – with a couple of days left to go.
“November 2021 rainfall total is now at an all-time record-breaking 530.2 millimetres (20.87 inches) and counting!” said Roger Pannett, Chilliwack’s volunteer weather observer and storm watcher.
Rainfall records for Chilliwack date back to 1879, and this month’s rainfall total exceeds previous November rainfall totals, of 516.6 mm in 1990, and 520.8 mm in 2006.
The record for a December total monthly rainfall was broken in 1979 with 586.2 mm of the wet stuff.
Here are the daily rainfall totals Pannett recorded in the second storm or atmospheric river event, over the past three days in Chilliwack:
Nov. 27 – 65.7 mm (Previous record that date, 53.1 mm, 1973)
Nov. 28 – 58.2 mm (Previous record for that date, 55.0 mm, 2003)
Nov. 29 – 12.8 mm (as of 9 a.m.)
So the storm total for the second event was 136.7 mm of rain, Pannett said.
Another 50 to 100 mm of rain is expected to fall on the Fraser Valley and Metro Vancouver starting tomorrow (Nov. 30), according to Environment Canada.
The latest system will be the third atmospheric river to hit the Lower Mainland in under a week.
Environment Canada has issued a special weather statement for the Fraser Valley, Metro Vancouver, Howe Sound, Whistler and the Sunshine Coast for another “prolonged period of heavy rain.”
