NWS Storm Reports via Twitter  experiment

Public Information Statement
National Weather Service San Juan PR
913 AM AST THU APR 15 2010

Effective April 15 2010, the National Weather Service will begin an experiment to search the micro-blogging service Twitter for user posts called Tweets that contain significant weather information.

An advantage of searching Twitter for weather reports is the capability to use recently added geo-tagging. Geo-tagging is geographical information that is associated with something, in this case individual Tweets. This information allows the National Weather Service to correlate each Tweet to its location when it was sent.

The National Weather Service expects that access to information from this widely used social media tool will help to enhance and increase timely and accurate on-line weather reporting and communication between the public and their local weather forecast offices. The reports will be carefully evaluated during the experiment to ensure quality and timeliness.
