Floodwaters have closed all lanes northbound of Interstate 5 at Slater Road, the Washington State Department of Transportation tweeted just after 5: 30 a.m. Tuesday, Nov. 16. “Significant amount of water on the road NB I-5 at Main St (MP262) traffic being diverted to Slater,” Washington State Patrol Trooper Rocky Oliphant tweeted at 7 a.m. Tuesday. Southbound traffic is also being affected in the area, according to Oliphant, who advised “hug the right lane where the standing water the most shallow. We have the left lane blocked but people keep merging back over after they pass us.” Oliphant also asked to avoid calling 911 to ask about the status of roads in the area.
