While yesterday’s rainstorm paled in comparison to the atmospheric river event we saw in November 2021, it was still enough to cause some frustration for drivers and pedestrians in parts of Metro Vancouver.
According to Castellan, some parts of the province did see records for December 4 that had lasted decades get broken. He also provided important context that, for daily records, it’s tough to measure accurately because it doesn’t rain every December 4.
The daily weather summary for BC shows total rainfall amounts for December 4 to the afternoon of December 5. The parts of Metro Vancouver and Fraser Valley that saw the most rain include Mission (97 mm), Squamish Airport (90 mm), West Vancouver (81 mm), White Rock (56 mm) and Vancouver Airport (54 mm).
Some records were set solely looking at December 4.
For downtown Vancouver, Castellan said the region was hit with 49.8 mm, with the last time Vancouver saw close to this much rain on December 4 being back in 2004 with 35.4 mm.
White Rock saw a long-standing record broken. In 1963, the region was hit with 36.8 mm of rain on December 4; yesterday, it saw 46.6 mm.
According to YVR Weather Records, the period between December 4 and 5 was the wettest two days Vancouver has seen in more than two years, since November 2021.
Dec 4th➞Dec 5th were #Vancouver‘s wettest 2 days in more than 2 years, since Nov 15th, 2021 with 57.5mm of precipitation. #YvrWx
