What is RSS?
RSS has several meanings: Really Simple Syndication, Rich Site Summary, and RDF
Site Summary where RDF in turn stands for Resource Data Framework. In
any case it is a method of summarizing the latest news and information
from a website in a lightweight form that can be easily read by any of a
number of news readers or news aggregators. The idea is to give users the
ability to quickly obtain the latest news and updates from a site in a
headline or news digest format. This in turn helps during high-traffic
periods by reducing the load on the servers.
What do I need to use the RSS feeds?
To use our RSS feeds, you need a feed reader or news aggregator installed on
These are applications that can be set to read the feeds on a recurring basis,
generally once an hour or so.
For more information on downloading an RSS reader, click here.
Once you have installed a feed reader or news aggregator, you simply add the
SPC feed address to the list of feeds in the reader. The installation
instructions for the readers will help you with that. If your newsreader or
aggregator uses "auto-discovery" then simply enter the main SPC address
(http://www.spc.noaa.gov/) and it will find the feed.

Why is the XML logo on the page?
The XML logo and the RSS logo are both currently in use across the Internet
to indicate to users the availability of RSS feeds from the site.
XML stands for eXtensible Markup Language, and is the basic lingo of the RSS
technology. We simply decided to display both logos.
