Ambient Devices says it will soon sell its Forecaster Umbrella (PDF) for commuters and other pedestrians who quickly need to gauge the day's weather before a walk. A simplified version of the company's own WeatherWizard (recently launched as the Wireless Weather Forecaster), the umbrella relies on a receiver built into the handle to download today's forecast from AccuWeather. An LED warns of inclement weather through light pulses: as the likelihood of rain or snow increases, the pulse rate of the LED increases to match and will beat as quickly as 100 times per minute if bad weather is all but certain. Ambient says the umbrella is not yet ready for a public debut but should be ready in 2007. [Via Gearlog]
