Northeast India is one of the rainiest pockets during the monsoon season. One big spell of heavy rain is likely over the region during this week itself. The approaching weekend could be more punishing for large parts of the mountainous states. The inclement weather conditions may lead to disruptions in communication and connectivity.
The low-pressure area over Jharkhand and the neighbourhood has become less marked. However, the associated well-marked cyclonic circulation persists up to the higher levels. This feature will trigger heavy weather activity over the eastern and northeastern parts of the country during this week. The harshest weather conditions are expected over the southern half of the region, covering Meghalaya, Southeast Assam, Nagaland, Manipur, and Mizoram, over the weekend.
The month of June has resulted in deficient rainfall across all states of Northeast India. Arunachal Pradesh and Assam have observed a large shortfall of 35–40% in rainfall. The north-south-oriented states of Nagaland, Manipur, Mizoram, and Tripura have fared slightly better. July is the rainiest month for the region, and any major deficiency is difficult to make up in the later months.

The presence of the cyclonic circulation over Jharkhand and its subsequent westward movement will influence the wind pattern over the northeast region. The low-level valley easterly winds, a sign of stable weather, will be replaced by moist and warm southwesterly winds originating from the Bay of Bengal. This speeding stream runs across Bangladesh to sweep the mountainous and rugged terrain of Northeast India. The region, being heterogeneous with jungles, mountains, valleys, and dense forest cover, adds complexity to the local weather.
Weather activity will start building up today and will cover the entire region on 3rd and 4th July. Widespread rain and thundershowers, with intense activity in the evening and night hours, are expected. Between 5th and 7th July, the severity of weather will peak, especially over Meghalaya, Southeast Assam, Nagaland, Manipur, and Mizoram. Severe thunderstorms with lightning strikes, torrential rain, and strong winds are likely during this period. This heavy weather activity may trigger landslides, impacting communication and connectivity. The region's water bodies also face the risk of overflowing, leading to flood-like conditions. Concerned agencies are advised to exercise caution and prepare for contingencies.
