Shower activity could increase this afternoon, so grab the umbrella after lunch. The word “umbrella” comes from the Latin word “umbra,” meaning shade. It was used in ancient Egypt, Greece, and Rome. The oldest reference to the umbrella in China dates to the year 21, and the king of Siam in 1687 gave them to his subjects. As noted in a previous column, Ambient Devices markets an umbrella that will alert you when rain is expected. It’s called the Forecasting Umbrella and if it is forecast to rain in the next 12 hours, the umbrella’s handle will flash. Data from AccuWeather.com activates the umbrella’s sensors, and can differentiate between storms, with fast flashes, and sprinkles with slow flashes. Oh, just like with an ordinary umbrella, you’ll still need to manually raise this battery-operated umbrella. Fastcast: (Ryan, One Word).
