The National Weather Service has initiated an Experimental Listings of Watches, Warnings, and Advisories by State and Territory. There is a national listing and one for each state and territory in three different formats: HTML, RSS 2.0, and CAP/XML. Common Alertings Protocol (CAP) is an non-proprietary standard data format for the interchange of hazard warning and reports.
These files are updated about every two minutes and the RSS feeds can be read using news aggregators or syndicated to any website.
This is an experimental service. Your comments and feedback, accepted through December 30, 2003, will help determine if it is continued.
