Northeast is considered rainiest pocket during the pre-monsoon season from March to May. However, the region remained deficit for 4 consecutive years between 2018 and 2021. This part of the country has also remained perpetually inadequate during last few monsoon seasons between June and September. Against all odds, pre monsoon 2022 has largely remained bountiful, especially for Assam & Meghalaya.
Northeast India is an heterogenous pocket with all types of terrain like hills, valleys, forests and rivers. Combination of these make it as weather sensitive and hazard prone, more so in the rainy season. Floods, landslides and catastrophic rains keep returning to this pocket at regular intervals. Disruption in communication and connectivity becomes a major issue during prolonged episodes of inclement weather conditions. Despite, scanty rains for the last few seasons, many areas have been ravaged by frequent floods.
Northeast India has 3 meteorological sub-divisions namely : Assam & Meghalaya (A&M), Arunachal Pradesh(AP) and Nagaland, Manipur, Mizoram, Tripura (NMMT). Assam and Meghalaya remains most vulnerable, possibly due to mighty Brahmaputra stretching across entire length from upper Assam to lower Assam. Pre Monsoon 2022 has lashed badly 31 of 34 districts of Assam which continue to reel under harsh weather conditions, albeit with short sigh of relief for the last 2 days.
Intense rains are expected to pick up again over Northeast, particularly for Assam & Meghalaya. Southwest monsoon is likely to reach anytime soon after making onset over Kerala. Mostly, light to moderate rains with isolated heavy falls are expected over the next 3 days. Intense weather activity with heavy to very heavy spells are likely from 28thMay onwards. Rising level of Brahmaputra may spell trouble again for Assam valley at the outset of monsoon itself.
