Mamdani and New York City Public Schools (NYCPS) Chancellor Kamar Samuels announced in a press release that all NYCPS buildings would be closed on Jan. 26 due to the extreme weather conditions.

All after-school programs, adult education and other school-based activities will also be canceled, with instruction continuing remotely for most students.

This was a difficult decision made with the safety of every family in mind, and I thank you for your flexibility."
