It may not be there. I'm with AT&T and even on the latest update (4.1.2), it's not there.

I can't find it on my Sprint phone either!

Description of EXTREME vs SEVERE alerts (from NWS web site):

Some cell phones allow the users to opt-in and opt-out directly on their devices. These devices differentiate the imminent threat alerts into two categories - "Extreme alerts" and "Severe alerts" as shown in the image below.

The Extreme alerts from the National Weather Service include warnings for tsunamis, tornadoes, extreme winds, hurricanes and typhoons. The Severe alerts from National Weather Service include warnings for flash floods and dust storms. For example, by keeping Extreme alert selected and de-selecting Severe alert, the user would still be capable of receiving Extreme alerts, but would not receive Severe alerts on their cell phone.
