From what I've seen of case numbers, and as you already know, the Delta surge is far worse in states with low vax rates. While cases have gone up pretty much everywhere, states with good vax rates are seeing far lower case numbers than they did before the vaxes were available. Reinstated mask mandates, etc. are just erring on the side of caution. I don't think the new mandates will last anywhere near as long as they did before. For the DMV, Delta is a strong aftershock after The Big One.
