Another terrible, fatal accident on the 10, between Phoenix and Tucson involving a motorhome and many others; please be careful! /www.theepochtimes.com/n3/334761-i-10-crashes-3-dead-12-injured-afte...
Just another comment based on my experience. I've seen these storms coming from the front of my vehicle. I didn't wait for it to get to me. I jumped off the very next off ramp and parked in a safe spot. It passed and was clear enough to drive in about 10-15 minutes.
I've also had them coming from behind (stay aware). I drove at 75mph, which is the speed limit on I-10 in most places, and was barely able to keep pace with it.
