Subject:  NWS Watches/Warnings/Advisories in CAP and ATOM based     
          Formats to Transition to Operational Status on
          March 15, 2011.

Internet based feeds of NWS watch/warning/advisory products 
using the XML-based Common Alerting Protocol (CAP) v1.1 and ATOM 
message formats will become operational on or about March 15, 
This announcement is a follow-up to the Public Information 
Statement entitled, Public Comments Solicited on Experimental 
Common Alerting Protocol Version 1.1 Messages, from 
August 22, 2008. 

The previous announcement stated that CAP v1.1 was expected to 
replace existing NWS CAP v1.0 messages.  Notice was subsequently 
placed on

http://www.weather.gov/alerts

stating that the replacement would occur gradually by March 15, 
The new date for replacement is March 15, 2011, coincident with 
the CAP v1.1 feeds becoming operational.  At that time, NWS CAP 
v1.1 and ATOM messages will become available at

http://alerts.weather.gov/cap/

Users targeting the CAP v1.0 and ATOM messages at

http://www.weather.gov/alerts

as well as the CAP v1.1 messages and ATOM messages at

http://www.weather.gov/alerts-beta

will be redirected to the operational CAP v1.1 and ATOM messages 
at the new location.

The Federal Emergency Management Agency (FEMA) announced the 
adoption of CAP v1.2 as the standard for emergency alerts in a 
press release on September 30, 2010.  The press release can be 
found at

http://www.fema.gov/news/newsrelease.fema?id=52880


The NWS is beginning work on CAP v1.2 and expects to offer an 
experimental CAP v1.2 feed of NWS alerts during the 
Spring/Summer of 2011.
