TréoCiel is a nifty little program dedicated to the Treo 650 mobile phone that gives me localized weather forecasts in a chart report, with the abiliy to update forecasts when and where needed!
The local weather charts give a whole week in a single view, and you can also receive detailed hourly forecasts for the next days -- temperatures, precipitation probabilities and wind speed.
All of the information is presented on a single scrollable chart (see illustration at left).
It's easy to use, easy to read and there when you need it -- what more could you want from a weather forecast!
