Starting tonight, look at One Rincon Hill to get your weather forecast. The top of the city's tallest apartment building will now use a nifty color-coded system of lights to signal the weather. Red: warmer weather ahead; blue: colder weather; green: 50-percent or more chance of rain; and amber: no change. The beacon will turn on at dusk every evening and will remain on all night. Using tall buildings as weather beacons is somewhat of a tradition. Syracuse, N.Y; Minneapolis; Dubuque and Des Moines, Iowa; Bismarck, N.D.; Toronto; and in two buildings in Brisbane and Adelaide, Australia have beacons. This is the Bay Area's first.



Boston's John Hancock tower famously reports the weather too:
Steady Blue: Clear
Flashing Blue: Cloudy
Steady Red: Rain
Blinking Red: Snow, or the Red Sox game has been cancelled.
no fair. i want 1RH's to blink too! but for what? for what??
If only One Rincon Hill could control the weather, since it looks like a tower fan.
How about it blinks if there is an earthquake?
Don't forget the giant Ferris(tm) wheel outside of the Osaka Aquarium, in Japan, which also uses its lights to signal tomorrow's weather.
I think the John Hancock can also tell you if the Sox won or not, and whether the game is/was home or away.
I too was going to mention the Hancock building... Glad we're getting our own 'weather building' here!
And if you can't see the lights = fog.
Useful possible codes for Market Street use =
Red: Some sort of white-people-type protest.
Green: Damn tourists.
Blue: Foghorn.
Flashing Blue: One parking space just opened up over there.
Flashing Red: Extra-strong scent of pee today.
Flashing Green: Mayor slept the sleep of angels OR Frank Chu in-progress.
Other ones y' can think of?
NYC's Mutual of New York tower had a star on it that would tell you the weather & a time display, too. I don't know if it's still there, though.
It's still a poor replacement for the 76 clock tower.
Will that stupid slot finally have a purpose?
God I hate that slot.
see, i LOVE the slot. makes the whole thing pop, really.
Woo! More like Sacramento every day!

God I hate that slot.
[sigh] That's what... he said...?!
(I'm the one typing it and it doesn't even make sense to me!)
Milwaukee does it too with the "weather flame" on its Wisconsin Gas building.

Wow! And I thought all it could do was ionize the city's air...
