FlashAlert utilizes the free service Twitter to distribute emergency text messages. While you are welcome to register your cell phone text message address directly into the FlashAlert system, we recommend that you simply "follow" the FlashAlert account for Tigard-Tualatin Sch.

Twitter sends messages out exceptionally fast thanks to arrangements they have made with the cell phone companies.
