Weather beacon lights up Rincon Hill

December 9, 2008 6:12:19 PM PST
The developers of a San Francisco condominium tower have established a weather beacon atop their 64-story building on Rincon Hill at First and Harrison streets.

The color of the lights indicate what tomorrow's weather will be -- red for warmer, blue for colder, green for rain, and amber for no change.

The lights are LED floodlights that burn very little energy.

Other cities have similar beacons, but this is a first for the Bay Area.
