Northeast India has been witnessing a poor show on account of rains for three successive seasons, i.e. monsoon, post monsoon and winter. According to the records available with Skymet, it is only Mizoram which is surplus by 13%, while the remaining six states in the region are deficit.
Northeast India and the Western Ghats are the major contributors to monsoon rains in India. During post monsoon season, all pockets of Northeast India remained deficient by over 50%. In winters as well, a similar pattern was observed wherein rains were dismal. The state of Tripura was the only pocket which was excess by 8%. Rest all regions remained deficient, with Manipur leading the states by a deficiency of 69%.
The pre-monsoon season commences from March. For the state of Northeast India, it is a transition period, wherein wintry conditions are still prevalent during the first half of March and by the second half of the month, pre-monsoon picks up pace. The day temperatures during this time reach 30°C, which is very uncomfortable due to humidity levels.
According to meteorologists at Skymet, Northeast India is the only pocket which has witnessed excess pre-monsoon rains so far. Northwest India is deficient by 5%, while the deficiency in South India is 49%. Topping the list of large excess is Assam and Nagaland, recording 115% and 219% of surplus rain, respectively. Meghalaya is the only state in the Northeast India witnessing a deficiency of 52%.
The rains during the first half of March is on account of Western Disturbances which travel from west to east and also the humid winds from the Bay of Bengal which blow over the region. Rain and thundershower activities in Northeast India since March 2 are on a move and expected to continue for another 24 hours. The western part of Northeast India would be more prone to these rains. Places like Jorhat, Tinsukia, Lakhimpur, Tawang, Itanagar, Pasighat, Kohima, Aizawl and Imphal would be a witness to some decent rains.
After 24 hours, rains will start receding and become confined to Arunachal Pradesh. Post this wet spell, a break of four to five days would be seen. The day temperatures over many places of Northeast India are in mid 20s and as the rains stop, the temperatures will settle in high 20s. Minimums will record in double digits.
