Due to the severe weather and flooding from the remnants of Hurricane Ida, students are advised to remain indoors and avoid flooded areas of campus. Report any water intrusion in your residence hall to Public Safety.

This text has been reconstructed from news coverage and may not reflect the exact original wording.

This advisory is reconstructed from The Quadrangle's after-the-fact reporting; no verbatim Jasper Alert text could be confirmed from an archive, so it is marked unconfirmed.
The instruction to report water intrusion to Public Safety reflects that the dominant on-campus hazard was building flooding — especially at Overlook Manor — rather than an outdoor threat.
Context

Background

Manhattan College sits in Riverdale, in the northwest Bronx near the Hudson and the Major Deegan Expressway. When the remnants of Hurricane Ida set New York City's single-hour rainfall record on the night of September 1, 2021, several campus buildings reported leaks and water damage, with the Overlook Manor residence hall hit hardest — students described water in their bathrooms and bedrooms and missed classes and club meetings for days afterward. Just below campus, floodwaters shut down the Major Deegan Expressway. The storm killed 13 people across the city, and the campus damage became part of a broader reckoning over extreme rainfall in the Bronx.
Analysis

Key Findings
