Tornado states allnurses -- Please check in!!! - page 4
Thoughts are with you. I used to live in KY and then in TN. I hate tornadoes!!! Hoping you and yours are all okay.... Read More
Nov 13, '02checking in from akron. didn't see a tornado, didn't hear a tornado, but heard the tornado sirens. they were all around us though. macedonia, twinsburg, canton. that night i didn't like living on the highest floor of an apartment building. we spent an hour or so in the inside bathroom...that was pleasant!!
Nov 13, '02quoted from tookie's postSorry to be ignorant CEN 35 what do you mean by F3 and F4's - is this there force measurement - we dont get them here - well at least not where we live.
gawd I hate tornadoes
Here in FL, the average tornado lasts only about 30 seconds, so we can't even warn anyone in the way.
But midwesterners get the really bad ones, so hubby and I became amateur radio ops and got Weather Spotter training when we lived in MO, in Tornado Alley.
All the local weather stations rely on NOAA, the government weather-radio people to get their information, and NOAA gets their information from local spotters. So having a battery=operated scanner does make sense, as SmilingBluEyes said; you'll get the info that much quicker, and you'll get other emergency information faster too, (like which roads are closed, etc)
Here's an interesting website on how tornado strength is measured: http://www.tornadoproject.com/fscale/fscale.htm
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 fores 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
A key point to remember is this: the size of a tornado is not necessarily an indication of its intensity. Large tornadoes can be weak, and small tornadoes can be violent.
