Well, it’s been a long time coming, but we are finally getting some serious rainfall this weekend! Creeks have been dropping to barely a trickle (Monmouth? Seriously, you couldn’t manage just a little more water??) but they should be recharged soon…
As of Friday morning, there is a special weather statement in effect for the Howe Sound area:
Special weather statement in effect for:
- Howe Sound
Heavy rain over the South Coast this weekend.
A major change in the weather pattern is in the works. The high pressure system that has trapped wildfire smoke over Southern B.C. will finally shift east thanks to a pair of incoming storms. The storms will merge two jet streams into a single river of sub-tropical moisture that will bathe the South Coast with the first significant rainfall in months.
Weather models are indicating 80 to 120 mm of rain over the South Coast between today and Monday morning. 20 to 30 mm of rain is expected to carry over into the mountainous regions of the interior during the same period.
Due to the drought conditions over these regions, the soil has a reduced capacity to absorb water. Heavy rainfall thus increases the risk of flash flooding. Additionally, given the recent prolonged dry period, road surfaces may become slippery resulting in poor driving conditions.
How this will effect the local canyons over the next few days is hard to guess. We’ll just have to keep an eye on the water levels to determine how safe they will be in the short term. There are plans for a fairly large group to descend Box Creek on Sunday, but that may have to change, depending on the rain’s impact. Another possibility is Britannia, which is generally more open, with avoidable flows.
At least one more group, that I know of, is coming from out of town next weekend. It will be interesting to see how the creek flows stabilize in the meantime.
