North Eastern region comprising eight hilly states is witnessing a rainfall deficiency of 27% in the first three of the four-month-long monsoon season, the Met said on Monday.
According to India Meteorological Department (IMD) officials in Guwahati and Agartala, the seasonal monsoon (June to September) rainfall is likely to be 93% of the long period average over the region comprising Arunachal Pradesh, Assam, Meghalaya, Manipur, Mizoram, Nagaland, Sikkim and Tripura.
According to IMD report, available with IANS, said that during the first three months (June to August) of the monsoon season the Nagaland, Manipur, Mizoram and Tripura sub-division recorded 1,013.1 mm (actual) of rainfall against the average rainfall of 1,227.9 mm. Though there is a 17 per cent deficit in monsoon rainfall, according to the IMD standard this is considered as normal.
IMD director Dilip Saha said: “Rain producing systems, including deep depressions, were not very much evenly active in the entire North Eastern region.” However, the huge deficiencies in rainfall were likely to be covered in the later part of the monsoon in Assam and Arunachal Pradesh,” he said, adding that frequency of movement of monsoon factors were also slightly favourable in Nagaland, Manipur, Mizoram and Tripura sub-division.
