The Fujita Scale

F-Scale Number Intensity Phrase Wind Speed Type of Damage Done F0 Gale tornado 40-72 mph Some damage to chimneys; breaks branches off trees; pushes over shallow-rooted trees; damages sign boards.

F1 Moderate tornado 73-112 mph The lower limit is the beginning of hurricane wind speed; peels surface off roofs; mobile homes pushed off foundations or overturned; moving autos pushed off the roads; attached garages may be destroyed.

F2 Significant tornado 113-157 mph Considerable damage. Roofs torn off frame houses; mobile homes demolished; boxcars pushed over; large trees snapped or uprooted; light object missiles generated.

F3 Severe tornado 158-206 mph Roof and some walls torn off well constructed houses; trains overturned; most trees in forest uprooted

F4 Devastating tornado 207-260 mph Well-constructed houses leveled; structures with weak foundations blown off some distance; cars thrown and large missiles generated.

F5 Incredible tornado 261-318 mph Strong frame houses lifted off foundations and carried considerable distances to disintegrate; automobile sized missiles fly through the air in excess of 100 meters; trees debarked; steel re-enforced concrete structures badly damaged.

What about doing something at MayFest in Fort Worth? I think it's the second weekend of May (that would be May 9-12). Friday night is always good, with the Fort Worth symphony doing the 1812 Overture with fireworks!

EXCELLENT IDEA!

Now that you post that, I remember more of what the weather dude said. He said that they often can't determine the windspeed inside a tornado, so they base the F- rating on the damage that results.

Houston? Don't worry, you've got until midnight to seek shelter in the community cellar(salt dome).

Speaking of bad tornadoes, that Jarrell one really raised this native's eyebrows. Sucked up the grass and pavement from the roads.

I'm east of Dallas in Mesquite and I have a program called Weatherbug. It gives a very good report on the weather for my zip code right here on my computer. It's free at Weatherbug.com. The only thing I did with it that I have to warn people about is that there is a warning sound like a chirp that I had to disable because of all of the alerts in Texas.

Breaking news: Apparently no more weather threats in Texas. The Weather Channel just broke in with an emergency broadcast of "Atmospheres".

Sheesh, what a waste that channel has become. Thank goodness for the internet.

You are right, I don't think they know. I seen one investigator at a tornado site trying to determine the strength of a tornado.. somewhere. He came to the instantious conclusion that is was an F5 as soon as he seen a Ford Escort driven into the girders of an overpass one mile away!

I remember reading a book on tornados back in the 1960's and at that time, they thought the windspeed could reach 500 MPH.

I got off here to look at TWC during the 4 PM hour,same thing.Do they really need a dinner break during an hour when there are that many severe weather warnings being issued?

Ain't that the truth! I have seen their radar, when severe storms are approaching, show the same imagery over an over for hours...after the storm had hit and left. I mean, if you kept looking at their radar, the storm never arrived yet! That station will get you killed!
