With the third atmospheric river event headed for B.C., the province will again close road arteries and thoroughfares.

Environment Canada has issued rainfall warnings for a number of regions, including Vancouver, the North Shore and the Fraser Valley, with some areas forecast to see 120 millimetres of precipitation. The 鈥減rolonged period of heavy rain鈥� is anticipated to last until Wednesday.

Some routes that were closed re-opened to essential traffic following the last rainfall event, but at a press conference today, B.C. Minister of Transportation Rob Fleming said closures are returning.

鈥淕iven current forecasts, we鈥檙e going to have to close Highway 99 once again, between Pemberton and Lillooet, that will happen at 4 p.m. today,鈥� said Fleming. 鈥淒rivers should expect some delays, as all traffic will be using Highway 3 and Highway 7 in that corridor to move in-and-out of the region, as Highway 1 remains closed in two locations, between Chilliwack and Abbotsford and east of Chilliwack, between Popkum and Hope.鈥�

The minister also said a travel advisory has been issued for Highway 20 and the Bella Coola Valley warning motorists not to venture onto the highway if it鈥檚 not necessary. Maintenance crews and avalanche crews are being staged along the corridor for fast response to conditions, he said.

Fleming advised travellers to drive with caution and expect delays.

鈥淚 do remind drivers that [Highways 3 and 7] are not up to the same condition before the first storm arrived two weeks ago,鈥� said Fleming. 鈥淪ome commercial truck drivers may not be familiar with these routes and we are asking everyone to please slow down, please be patient and accept that it will take longer and drive according to current conditions.鈥�
