ALERT2 / Background
The ALERT2 protocol specification was developed to provide a way to transmit data critical for flood warning over radio frequencies. ALERT2 is an update to the original ALERT protocol, which had limitations.
See the following for specification details:
ALERT2 Comparison to ALERT
TODO smalers 2016-12-10 need to fill in discussion of ALERT limitations and how ALERT2 overcomes these limitations - see the introduction of the ALERT protocol. Would be nice to have illustrations that the average person can understand.
ALERT Users Group
The ALERT Users Group is a group of representing interested entities such as government agencies and vendors who maintain and advance ALERT technologies.

- NOAA's Hydrologic Information on the Web - A Manual for Users - provides examples of NOAA flood forecasting offereings
The following are historical documents:
- Historical ALERT2 Documents:
- Early ALERT 2 Protocols, ALERT Users Group, May 2008 - presentation by Chris Roark and Don Van Wie
- ALERT-2 resources at Salo IT Solutions - Salo is company that received a Small Business Innovation (SBIR) Grant to explore developing an alternative to legacy ALERT protocol - This is independent of the Hydrologic Warning Council ALERT2 protocol and should not be confused with the current ALERT2 protocol; however, the effort provides background on legacy ALERT limitations
