Bihar, Marathwada, Rayalaseema Remain Rain Deficit: Northeastern States Perform Poorly
One-third of the monsoon season is over, and the seasonal rainfall is 15% more than the long-period average. However, 14% of the total area of the country has a significant shortfall due to scanty rains. The rain deficit pockets in the plains include Bihar (-50%), Marathwada (-39%), and Rayalaseema (-38%).
In the mountainous region, Arunachal Pradesh (-39%), Assam & Meghalaya (-40%), and Sikkim and Sub-Himalayan West Bengal (-37%). The island territory of Lakshadweep is rain deficit by -44%. All these deficiencies are huge and leave some anxious moments for the agriculture sector.
Most of the monsoon systems originating over the Bay of Bengal have tracked along West Bengal, Jharkhand, Chhattisgarh, and Madhya Pradesh. Flanks on either side of the track have witnessed poor rainfall. The South Peninsula, as a unit, has witnessed poor rains for the last two weeks or so. Rains have been poor over Tamil Nadu, Kerala, Karnataka, Andhra Pradesh, Marathwada, and Telangana. The seasonal surplus incurred earlier on account of decent rains is getting consumed, and most parts are likely to turn further deficit, with a shortfall of over 20% rainfall.
Heavy rainfall over the next 5–6 days will remain confined to the states of Jharkhand, Chhattisgarh, Madhya Pradesh, and Rajasthan. Rain deficit will grow further over Bihar, Marathwada, and Rayalaseema during this period. With the shift of the monsoon trough to the north and formation of a low pressure later, Bihar will get moderate rainfall between 15th and 20th July 2025. However, Marathwada and Rayalaseema divisions are not placed suitably for any major change in the weather activity over the next 8–10 days. Sikkim and Sub-Himalayan West Bengal and Assam & Meghalaya are likely to have fairly widespread rain and thundershowers between 15th and 17th July. These will not be adequate enough to compensate for the shortfall.
