Under the current order, TCWS No. 1 automatically suspends only Kindergarten classes in the affected area; TCWS No. 2 automatically suspends face-to-face classes from Kindergarten through Grade 10 (shifting to modular learning), and higher signals or Orange/Red rainfall and flood warnings extend suspension further. Senior High School, college, and work suspensions are not automatically triggered by low-level signals unless a local government unit or school head separately declares one - so 'a signal is up' does not by itself mean a given grade level or workplace is off.",
