A public record, rebuilt from the original sources
Hazard events in New York City, 1958 onward
Every hazard event the National Weather Service recorded for the five boroughs and New York Harbor, with the deaths, damage, station readings, complaints, water levels and federal declarations filed against each one. Each figure carries its source, its period and its status.
This is an experimental project, not an official one. It is an independent reconstruction from published federal and city data, built to see whether the record can be read in one place. It has no standing, it can be wrong, and no agency has checked it. For anything authoritative, use NYC Emergency Management and its own Hazard History and Consequence Tool.
Four events, four different measures
Each is the largest in this record on the one measure named beside it, and on no other. The record does not rank events.

Reading the record
- An event is one National Weather Service episode: one weather system, holding one or more records. Two episodes are merged by hand, and any merged event says so.
- All hazard types have been recorded only since 1996. Before that the database holds tornado, hail and wind alone, so an early decade counts what was collected as much as what happened.
- A measure nobody collected is never printed as a zero. Five statuses separate a real zero from an absence, and they travel into the downloads as their own columns.
