Looking Forward

In Your Opinion, Are There Too Many Tornado Warnings?

• No, I Want to be Warned Any Time There is a Potential Threat of a Tornado.

• Yes, Tornado Warnings are Issued For Too Many Marginal Events.

• Yes, Perhaps There Should be a Different Alert For Radar Indicated Tornadoes

• Yes, Tornado Warnings Should Only Be Issued When A Tornado Is On The Ground

What Are Your Thoughts On Storm Based Warnings (Polygons)?

• I like them, they are more precise

• I like the old county based warnings better, they are less confusing

• I don’t have a way to access them, so they are irrelevant

• I have never seen this

When a Tornado Warning is Issued for Your Location, What’s Your Expectation?

• That a Tornado Will NEARLY ALWAYS Occur in the Warned Area

• That a Tornado Will SOMETIMES NOT OCCUR in the Warned Area

• That a Tornado Usually Doesn’t Occur When Warnings are Issued

The National False Alarm Rate for Tornado Warnings is 76%

But 70% of All Tornadoes Are Warned For…Would you Like to:• Leave it as is• Have a Lower False Alarm Rate, at the

Expense of More Unwarned Tornadoes?• Have a Higher False Alarm Rate and Catch

Even More Tornadoes With Warnings?
