The contest is a call for developers to build weather-inspired apps that utilize the Weather Underground API and Twilio APIs, with the goal of predicting severe weather warnings through voice and SMS integration, among other possibilities. The grand prize winner will receive a Vantage Vue Wireless Weather Station package, while second-place winners will get a Kindle filled with programming and technology books. Developers have two weeks to submit their apps, which must include video or screencast submissions, and meet specific contest rules. This is one of Twilio's monthly developer contests aimed at encouraging developers to solve problems and showcase their skills using the Twilio platform.
