If a tornado warning is issued and the sky becomes threatening, move to your designated place of safety. Turn on a battery-operated radio and wait for further instructions. Tornado season is generally March through August, although tornadoes can occur at any time of the year. Yes, tornadoes tend to occur in the afternoons and evenings. Over 80 per cent of all tornadoes strike between noon and midnight.
Some tornadoes appear as a visible funnel extending only partially to the ground.
Look for signs of debris below the visible funnel. Before a tornado hits, the wind may die down and the air may become very still. An approaching cloud of debris can mark the location of a tornado even if a funnel is not visible. Tornadoes generally occur near the trailing edge of a thunderstorm. It is not uncommon to see clear, sunlit skies behind a tornado.
