Heavy winds lash Kolleru, raise fears of tornado

Heavy winds raising fears of a tornado lashed the Kolleru lake on Thursday afternoon. The wind lashed the lake area for about 20 minutes. The people surrounding the lake near Eluru feared a tornado. But the wind speed weakened gradually. Last month also, a similar phenomenon occurred. At that time also the people feared a tornado. Tornadoes are unheard of in the area. Tornadoes are the result of a very large thunderstorm. During a storm, the cold air and warm air combine. The cold air drops down while the warm air rises up. The warm air twists and turns into a spiral and forms a funnel cloud.
