Eliza Shapiro reports in The New York Times:

New York City’s entire public school system will shutter on Thursday, Chancellor Richard A. Carranza wrote in an email to school principals, in a worrisome signal that a second wave of the coronavirus has arrived. Schools have been open for in-person instruction for just under eight weeks.

This is no great surprise to me, despite having hear Mayor de Blasio say the contrary just yesterday on the radio.
