The Yahoo! Weather RSS Service
The Yahoo! Weather RSS service allows you to keep track of the weather at your favorite locations in an RSS reader or on
My Yahoo!
.
The simplest way to subscribe to an RSS feed is to go to the page for your favorite city and click the orange RSS button.
You can also make custom links to whatever city you'd like. The Weather RSS Service takes two parameters:
'p'
for the location identifier. This can either be a US Zip Code or the location ID as displayed on Yahoo! Weather.
'u'
for units preference. (F)ahrenheit is the default. Use 'C' for celcius.
These links all return the weather forecast for Sunnyvale, California with temperatures in fahrenheit.

For application developers
While the Weather RSS feeds provide human-readable HTML in the description tag, we've also extended RSS so the weather data can be used by application developers. In fact, the weather widget in
Konfabulator
uses this same RSS feed. You'll find this data in expressed in the 'yweather' XML namespace. Below are some sample tags and descriptions of their attributes.
