Another Pineapple Express drenched Metro Vancouver Thursday morning, and a lot more rain is forecast to fall before the weekend.

The series of storms prompted a rainfall warning from Environment Canada, which urged residents to watch for possible washouts near rivers, creeks and culverts.

The agency said most of the region should see 50 to 80 millimetres of rain by the end of Friday, while Howe Sound and the North Shore Mountains could see up to 120 millimetres.

“Usually you see a system like this once a day, once every other day. We’ve got three of them happening in probably less than 48 hours,” said Marke Driesschen, CTV weather specialist.

The last Pineapple Express, which hit on Jan. 23, turned parking lots into ponds and was blamed in a number of car accidents.

Mounties have already cited the latest storm in a serious pedestrian crash that left two people in hospital Wednesday night in Surrey.

The RCMP said a dark pickup truck slammed into two pedestrians in the 12200-block 0f 90th Avenue, throwing one of the victims into a water ditch.

Both victims, who were wearing dark clothing and walking with their backs to traffic, remain in hospital in stable condition.

The storm should also be hard on local ski hills, according to Driesschen.

“Forget about seeing any snow. It’s called Pineapple Express because it also gets warm,” he said.

Recent weather has been so rough on one Fraser Valley ski hill that it’s decided to close for the season. The Hemlock Resort said it only got “negligible” snowfall and is shutting down due to “extremely unseasonable conditions.”

The mountain is about two hours east of Vancouver, between Mission and Agassiz. People who purchased season passes can get refunds or have their passes honoured next year.
