Some rural areas use a different type of technology to learn about storms like those that swept through rural Nebraska last weekend.
No sirens went off in Furnas County because no visual tornadoes were spotted, but emergency managers say many residents did receive a warning thanks to a service called "Code Red".
About 600 subscribers use the service. Officials say along with traditional methods it's proven to work even when power was cut off to cell towers.
"I have a lot of confidence in this system especially with people carrying cell phones, I think it helps a lot," said Furnas County Emergency Manager Roger Powell. "It did Saturday night, it did, In fact we got two calls on two different warnings for majority of our county."
Information on "Code Red" can be found on the front page of the Furnas County website.
