Storm This Sunday AZ?

I have drove to AZ from LA & SD in S. CA several times with no problems, but a couple of times I have been scared to drive under mother natures conditions without warning.  1 time in Pine Valley it was snowing on my way back from, AZ & another sand storm with major wind factors, plus added agua from raining is overwhelming.


Do you think the storm this weekend will be bad for long trips?  I believe it is set to occur Sunday night, and continue until late Monday.
