Marietta, GA
My tornadoAlert warned of SEVERE WEATHER approximately 20 miles from my location in Marietta, GA at 3:33PM on May 25th. It had already alerted us for approaching NONSEVERE threat conditions. The warning preceded Natiuonal Weather Service warnings for the area south of us by 20 minutes. The SEVERE WARNING condition reverted back to NONSEVERE in about 10 minutes as the threat moved away from my area. Prior to that, the NONSEVERE front tracked the approach and approximate distance from our location accurately. The fact that the unit updates the threat type and its approximate distance every 60 seconds gave me unprecedented situational awareness. – May 26, 2015
