Well, then it could be just rumors. With that being said, the rumor is they will stand down BUT as I stated elsewhere, time will tell.
So much hype....
What I know is happening, I have friends involved in local emergency management (and some of this has already been reported in the news): the two large office buildings and associated parking garage at 5th St and Van Buren closed at 1 pm, all employees were sent home. Chase Field/Diamondbacks employees are being sent home early. The Maricopa Superior Court buildings closed early, employees being sent home early.
