Announcements for school closing are recorded on the school's voice mail system. The Catholic High School of Baltimore follows school closings/delays for inclement weather according to Baltimore County and/or Baltimore City announcements. For instance, if Baltimore County is closed and Baltimore City has a two-hour delay, Catholic High is closed. If Baltimore City is closed and Baltimore County is delayed, Catholic High is closed.

Tune into WBAL 1090 AM for a complete list of school closings and delays.

No separate announcement is made for inclement weather closings/delays for Catholic High unless Catholic High has a special schedule that day, like during exam week. In that case, a separate annoucement will be made.
