Memory's fuzzy - did the storm not make communication difficult? What would be the point of leading them out to a terrible storm very far from the Prometheus, with all the vans and RVs parked in the garage?
From what I recall just when they were starting to lose their way Janek's like "goodnight the storm's gonna make talking a bitch" and they're like "ahh f**k you but we'll see you in the morning so fine we'll deal with this later." Pups did their job, and getting lost was no big deal, handwaved because Fifield and Milburn didn't expect to get killed by the hammerpede that night.
From what I recall, anyway.
