I use this site for a quick fix on monthly UE rates. It's close enough.

NY's 3-month average unemployment rate is currently 7.7%. It needs to drop to 7% to lose Tier 3.
The current 7.7% is based on:
07.5% - June
07.6% - May
07.8% - Apr
22.5%/3 = 7.63% (BLS has rounded up to 7.7 - not sure why)
Emergency Unemployment Compensation Trigger Notice Report
In any event, in order for NY to trigger off Tier 3 in September, the July UE rate would need to be 5.4%, which clearly isn't happening. Even if August showed 7%, July 7%, June 7.5%, NY still remains triggered on, as its 3-mo average UE rate at 7.1% still meets the 7% trigger.
NY isn't losing Tier 3 anytime soon.
You're worrying about nothing, imo.
