400 km is almost 250 miles. 248.5485 to narrow it down. ...
And? The IA event was definitely a long run -- I've not found a record but some have continued off the east coast out into the Atlantic where there were no measurements undoubtedly have gone even longer before they finally fell apart.
The bow front from August 11 expanded from about 70-80 miles at 6AM before it even got to IA to something over 500 miles by 8 PM
Which makes the event more than just a downburst by definition...of course, one may not know it's more than that at the time in any one location w/o additional input; particularly on the formation end before has grown immense in proportions.
The links to pictures I posted above near here, one of which was within about 30 miles if I recollect the specific links correctly make it obvious as it was on its way this was more than just a single cell...
We did have time to close up the barn and machine shed and put stuff inside before it hit since was still daylight.
In Florida they can predict the weather in the summer a year or more in advance. "Hot with a chance of showers and some may be locally severe, with intense lightning and maybe a little tornado". ;-)
The hurricane predictions are actually pretty good if you think a +/-
300 mile wide 2 day cone is good. If you want to know if the thing is going over your house, they are less than an hour out. Sometimes less than that with a storm like Charley that turned in about 15 minutes.
I agree. Weather is the biggest cause of home repair in plenty of areas of the US.
It depends a lot on the wind code they build to, Unfortunately that is
80 or less in most places. It is 150 here and 160 a few miles west of me.
You don't think that tornado alley has similar requirements? Why not?
Some can be chopped into silage, however.
I think they just gave up and decided the tornado is taking it anyway. FEMA does have tornado proof structure plans but that is not the standard building practice. They will just build safe rooms instead of underground shelters.
Florida may have the strongest wind code in the US (I would bet on it) but I could be wrong. I think we are also the only state that separates wind storm from homeowners insurance. (similar to flood),. It is an additional policy. I suspect that is because a tornado (F3-F5) is total devastation down that narrow path but 50 feet away things are OK. Overall the damage gets amortized over lots of customers who were OK. A hurricane can wipe out whole counties even wide spread damage across most of the state. It is a different risk category. By building to a substantial wind code, most damage is averted. It is the same with strictly enforcing the FEMA Flood plane.
