Heavy rains lashed Vizianagaram, Visakhapatnam and Srikakulam districts of Andhra Pradesh (AP), bringing relief to the people suffering from scorching summer heat. While Bay of Bengal has turned red in Vizag, thunder and lightning accompanied by heavy gales are causing havoc in Vizianagaram. It has been raining in Visakhapatnam Agency area since last night. About the sea water changing colour, the Met department officials said that it might be due to 'new' water entering. Also, the entire Northeast of the country might be struck by similar conditions in the next few days, they said.
