The district said Paradise Valley Road is closed at the Paradise Valley Bailey Bridge and Squamish Valley Road is closed at the Pilchuck Bailey Bridge.
“There is some impact to property,” Squamish Mayor Sean Easton said. “We don’t have a clear description of what that looks like at this time. The stay in place order is still active as we’re waiting for river levels to recede.”
The district says river levels are expected to peak today and begin to drop as rainfall from the storm works its way through the river system.

Easton said the district is used to big storms and heavy rainfall, and is preparing for another weather system on the weekend.
“We’re trying to respond in this moment, but then also trying to look at it and make sure that we’re ready for the next storm moving through,” he said. “It’s unclear what that storm looks like, as far as amounts at this time.”
He said the district’s emergency operations centre is monitoring the situation.

Pemberton Valley and parts of the South Coast are under a flood warning, with the River Forecast Centre saying river levels there “have been rising rapidly since late Tuesday night” and are expected to continue to rise into Thursday.
“There’s still quite a bit of uncertainty in the weather forecast,” said David Campbell, head of the River Forecast Centre.
“That’s something that we’re going to continue to monitor closely over the next couple days here as we get into the weekend, and whether there’s any kind of additional flood hazard through that period.”
The centre has also issued flood warnings for the Kingcome River and Vancouver Island.
High streamflow advisories are in place for southern Vancouver Island, the Fraser Valley, Fraser Canyon and Chilcotin.
Environment Canada has rainfall warnings in effect for east, inland and west Vancouver Island, as well as parts of the Sunshine Coast.
