project management question:

The project you are managing as expecting it's first shipment of equipment to install and test at the customers premise in Denver. it is imperative that the equipment insulation is on schedule since the Denver location is the hub of the Network operation. As of the writing, the schedule is exactly on target. The shipment of goods is proceeding east of I-70 just west of Glenwood Springs. Due to the recent forest fire on storm King Mountain, at Glenwood Springs, all vegetation has been destroyed which results in devastating mudslides that block I-70 in both directions. The delay may last up to five days. The sides could continue depending upon weather conditions. although the rains have subsided, the last weather report shows that there is a 50% rainfall forecast expected within the next 48 hours.

what are four risks involved in this scenario?
