While Metro Vancouver received over twice the average amount of rainfall for September, the start of November has been unseasonably dry.
In fact, Vancouver just broke the record for the longest stretch of no precipitation ending in November. What’s more, the forecast calls for clear skies throughout the day tomorrow, which might make the dry stretch even longer.
Vancouver Is Awesome spoke to Armel Castellan, a warning preparedness meteorologist with Environment Canada, about the record, as well as what the Lower Mainland has to look forward to over the long weekend.
“To clarify, we categorize dry days as those that have under two millimetres of precipitation, which we register as a ‘trace’ amount,” Castellan said.
“This could mean a light mist or shower or even a very brief period of rain could happen on a ‘dry’ day.”
With this in mind, Castellan notes that this amount of precipitation isn’t enough to “tip the bucket.” A tipping bucket rain gauge is used to determine how much precipitation falls from the sky.
Castellan adds that the last day Vancouver had enough rain to tip the bucket was Oct. 25, when the Vancouver International weather station registered 3.6 millimetres of rainfall. Since then, there hasn’t been a single day with more than a trace amount of precipitation.
“The dry stretch officially started on Oct. 26 and it has carried through to today. It looks as though it might carry into tomorrow, as well.”
Although Friday night’s forecast calls for a chance of rain, Castellan notes that they expect that to happen overnight. As such, the amount of precipitation might not be enough to register more than a trace amount.
Vancouver broke the record for the longest stretch of no precipitation ending in November today with a whopping 13 day dry run. The previous record of 12 days was set in 1956, and began on Nov. 19 and ended on Nov. 30.
Castellan notes, however, that the weekend forecast isn’t looking particularly dry. While it doesn’t call for any torrential downpours or powerful winds, he notes that each day of the long weekend calls for a decent chance of precipitation. With that said, the cloud coverage will allow for warmer nights.
