Need help finding map

[Alex Heimberger]

Found an interesting map a few days ago on the SPC website & can't find it today. Want to show someone. The map was total number of tornadoes by counties. Believe the highest was a county northeast Colorado with 200+ tornadoes total. I've been looking tonight & no luck. Was hoping someone on here knows what & where this is. Link would be great. Thanks, Alex H.

not sure if this is exactly what your looking for but if you click on "by county" on the map of tornadoes per 10k sq mi youll see a map of similar effext. also showing Weld county Colorado (I beleive) as the highest from 1952-2010. with kansas being the highest by state. from 1991-2010

Here's another map from U.S. Tornadoes (yeah I'm pimping out the site again )

http://www.ustornadoes.com/2012/05/22/map-u-s-tornadoes-by-county-1950-2011/

The interactive map lets you hover over each county the exact number of tornadoes. For 1950-2011, Weld County, CO is indeed the highest at 252. Second place is Harris County, TX with 213. Those counts are for any tornado that went through the county at some point.

Scary to think that Weld County is within walking distance of my house (I live in eastern Longmont which crosses slightly into Weld County from Boulder County and I happen to live maybe half a mile from the county line). Interesting note for that map that Mark posted: the article also lists a few other tornado-prone counties and among the highest it lists are Washington and Adams Counties, both in Colorado. Though I never knew that Harris County, Texas ranked second with over 200 confirmed tornadoes as well.

The thing that must be mention regarding Weld County Colorado is that a vast majority of the tornadoes recorded there are weak, short lived tornadoes and/or landspouts. The most powerful and longest track tornado on record there was the Windsor tornado in 2008 (an EF-3), a distinction that tornado shares with Larimer County. There have been several F/EF-2 tornadoes, but ~98% of all tornadoes there are EF-0 or EF-1.
