The Cyclone ‘Mora’ forming over the Bay of Bengal will likely turn into a severe cyclonic storm in the next 12 hours, helping further advance the southwest monsoon into parts of Arabian Sea and Bay of Bengal by May 30-31, and bringing heavy rainfalls to northeastern states of Assam, Meghalaya, Tripura, Mizoram, Manipur, Arunachal Pradesh and Nagaland, the met department has said.
Further, the Cyclone Mora, a deep depression formed over the Bay of Bengal, will also help the southwest monsoon to advance and settle in over the state of Kerala with the first rains expected around May 30-31, the Indian Meteorological Department said. “With the strengthening of westerlies and likely northward shift of the shear zone, conditions are also becoming favourable for further advance of Southwest monsoon and its setting in over Kerala and parts of northeastern states around May 30-31,” the Indian Meteorological Department said in a bulletin.
Earlier today, the Cyclone Mora lay centred near Paradip in the Bay of Bengal, which is expected to trigger heavy rains in Odisha in the next one-two days, the met department said, adding that the deep depression is likely to intensify into a severe cyclonic storm by 29 May-30 May and cross Chittagong by the noon of 30 May. This will bring “heavy to very heavy rainfall” in Assam, Meghalaya, Tripura, Mizoram, Manipur, Arunachal Pradesh and Nagaland, IMD said.
The situation is also likely to bring monsoon to the eastern parts of India at around the same time as the southern state of Kerala, the met department said. “Conditions are also favourable for the advance of southwest monsoon into northeast segment of India covering Nagaland, Manipur, Mizoram and Tripura during May 30-31,” it said in the bulletin. The met predicts heavy rains, accompanied by thunderstorms across Kerala, Lakshadweep, Andaman & Nicobar islands and in northeastern states during June 3-5.
Earlier last week, the met office had said that India is due to receive a ‘normal’ monsoon and more rainfall this year than the previous year, as the concerns over the El Nino weather condition has eased. It had also said it expects the monsoon to hit the coast of Kerala state by May 30, two days ahead of previous expectations, bringing relief to a heavily agri-dependent economy. Indian Meteorological Department defines 96%-104% rains of the long-period average as ‘normal’, that below 96% as ‘below normal’, and below 90% as ‘deficient’.
