Long Island, New York
Steven Bellone, County Executive
Each Flash Flood Warning (FFW) will contain a bulleted format of easily readable in formation
describing the flood flash, the source of the information (e.g., radar, gauge, trained spotter,
Emergency Manager), and a brief description of the impact of the flash flood. It will also
include machine readable tags to characterize the flash flood damage threat, source
information, and causative event.
WEAs will be limited to only those FFWs with the damage threat tags of “Considerable” or
“Catastrophic.” T hird party vendors will be able to identify and extract the “emergency”
language in the FFWs.
With this change to impact based FFWs, the NWS is aiming to improve the public response to
Flash Flood Warnings by providing easily readable information and issuing WEA alerts only for
flash flood events that require immediate life saving action.
What is WEA?
Impact-based warnings contain hazard, source, and impact information, and additional damage threat tags. On the right is a sample impact-based warning.
Hazard, Source, and Impact Information
Each Flash Flood Warning (FFW) will contain individual lines that clearly state hazard, source, and impact information.
Tags will appear at the bottom of FFWs and in Flash Flood Satements (FFSs), which provide supplemental information on active FFWs.
NOTE: The colors in the left column do not translate to the actual product and are only meant for visualization purposes in this presentation or associated internal/external outreach.
