Tornado
Tornado: A violently rotating column of air extending from a thunderstorm cloud to the ground. The Enhanced Tornado Intensity Scale is used to categorize tornadoes
Funnel Cloud: A condensation funnel extending from the base of a towering cumulus or cumulonimbus, associated with a rotating column of air that is not in contact with the ground (and hence different from a tornado). A condensation funnel is a tornado, not a funnel cloud, if either a) it is in contact with the ground or b) a debris cloud or dust whirl is visible beneath it.

39-54 mph: Twigs break off trees; wind generally impedes progress.
55-72 mph: Damage to chimneys and TV antennas; pushes over shallow rooted trees.
73-112 mph: Peels surfaces off roofs; windows broken; light mobile homes pushed or overturned; moving cars pushed off road.
Dense Fog:
We are mainly interested in visibility reports of a half mile or less.
