Enter multiple zip codes in the form above and submit to build a weather map.

Yahoo! is publishing Weather in geocoded RSS.
And their Mapping API builds annotations from geoRSS.
So I connected them together.
Here, the weather feeds for your zipcodes are merged together with Magpie RSS and submitted to Yahoo! Maps.

mapufacture also maps geocoded RSS, and it can be read and parsed in javascript for Google Maps.
There is now an option to try those services as well.

Geocoded RSS rocks!
