What happened
The episode as NWS AFG wrote it up.
Heavy rainfall in excess of an inch on the 22nd into the 23rd caused the Taylor Highway to be closed in two spots. The first road closure lasted approximately 11 hours and occurred in the Jack Wade area between mile posts 83 and 86, and was caused by a washout. The road closure blocked access to the Canada border via the Top of the World Highway, which connects with the Taylor highway. The second road closure, occurred between mile posts 114 and 116 as mudslides blocked the road.
