wow. Looks like they are getting a situation similar to what a strong TS would bring! 80mph+ gusts are quite intense.

It can not be a hurricane because of a few factors:

-It is not a true-tropical system (no start in the tropics)
-There have been no reports of sustained hurricane force winds (just gusts)
-It is over land

Also, if it rolled off the east coast it would never become a hurricane because:

-The waters off the east coast are not warm enough
-This system has no warm-core tropical roots
- This, climatologically, is not a good time of year for hurricane development.

Could it become a subtropical storm? May be...but I doubt it. Either way though: it is a potentially dangerous low pressure area, and many in it's path will see gusts in the 40-50mph range (with a few stronger areas of wind over the northern plains and the great lakes). This is certainly an interesting occurrence though none the less..and something I will be watching for sure!

Also, here is an update for current winds associated with this storm:

North platte, NE: 25mph gusts
Valentine, NE: 28mph gusts
Butte, NE: 24mph gusts
Lake Andes, SD: 25mph gusts


**Looks like the area of wind has really calmed down after sunset!<<Another reason this is not a hurricane.**
