Think about this. The Fujita scale ranks tornadoes from their weakest (F0) to strongest (F6). The scale is as follows:

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 forests 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-inforced concrete structures badly damaged.

F6 Inconceivable tornado 319-379 mph These winds are very unlikely. The small area of damage they might produce would probably not be recognizable along with the mess produced by F4 and F5 wind that would surround the F6 winds. Missiles, such as cars and refrigerators would do serious secondary damage that could not be directly identified as F6 damage. If this level is ever achieved, evidence for it might only be found in some manner of ground swirl pattern, for it may never be identifiable through engineering studies

Now considering that all of the weather reports as of this writing are showing sustained winds of 145 mph and gusts up to 180 mph, do the math. This is basically one big ass tornado. If you are in the warning area, the time to leave is now. Don't wait until you can get caught on the road. This is one rough ass bitch. If you hunker down, my prayers are with you (seriously).

I am not trying to deliver a meteorology lesson, but I want to make sure that the folks in the affected area realize what they're dealing with.

Good Luck

You are right about hurricanes being big tornado's. The biggest difference is that the winds from a hurricane last much longer than the winds from a tornado.
