Victoria Day wasn't just wet in Chilliwack, the downpour was the biggest ever for a May 21, according to Roger Pannett, volunteer weather observer for Environment Canada.
Total rainfall was 40.2 millimetres (mm), shattering the previous May 21 record of 23.1 mm in 1943.
That one day of rain went a long way towards upping the monthly total closer to the average. After weeks of warm, dry weather, the 40.2 mm meant that 54.8 mm has fallen in the month of May.
The 30-year average rain for May is 98.3 mm.
Rain and warm weather could affect river levels. However, the head of the province's River Forecast Centre said fairly stable weather conditions in the Interior over the next few days should reduce the risk of a high Fraser River freshet in the short-term.
As of Wednesday morning, the forecast for Friday and Saturday in Chilliwack was sunny with a high of 24 C and 23 C respectively.
Sunday is expected to be cloudy with a high of 18 C.
Environment Canada does not have a weather station in Chilliwack. Local data comes from measurements taken in Agassiz.
