1.2 System Description
System Purpose

The purpose of the HazCollect system is to eliminate potential communications delays or errors due to manual re-keying. Valid NWEMs transmitted via HazCollect are entered directly into the NWS dissemination systems. (For further information, see Net Links below to access National Weather Service Instruction 10-1708: All-hazards Emergency Message Collection System.)

At the same time, EAS broadcast is requested. It is important to note that all NWEMs transmitted via HazCollect are intended for EAS broadcast. If you do not intend for your message to activate the EAS system, do not use HazCollect to send it. Instead, contact your local NWS office for alternate methods.

NWEM Pathway

The following describes the path of an NWEM transmitted via the HazCollect system:

  1. The message is composed at the sender's computer using NWEM authoring software.
    1. NWEM authoring software is provided free of charge within DMIS Desktop Tools to qualifying organizations (see Lesson 1.4).
    1. Other third party authoring software may also be used.
  1. The NWEM is transmitted over the Internet through the DM-OPEN Web services system to the HazCollect server. (Access to DM-OPEN Web services is described later in this chapter.)
  1. The HazCollect server:
    1. Validates the sender and the geographical area (county FIPS code) for which the sender has been authorized. (Access to HazCollect is described later in this chapter.)
    1. Reformats the message to conform to NWS technical requirements.
    1. Does NOT evaluate the appropriateness of the warning or the actual message content. That remains the responsibility of the sender.
    1. Transmits the message to the NWS dissemination systems, including NOAA Weather Wire Service (NWWS), EMWIN , NOAAPORT, and NOAA Weather Radio All Hazards (NWR), and for relay to the Emergency Alert System (EAS).
  1. The NWEM is received by the NWS Advanced Weather Interactive Processing System (AWIPS), where the text message is converted to voice for broadcast over NWR and EAS.
  1. EAS participants broadcast the NWEM over radio and television, in accordance with locally-defined policies.

Tip Tip Since HazCollect relies on the Internet for communication, revert to direct contact with your WFO for backup if your Internet connection is disrupted.
