A low pressure area is likely to form in the next 24 hours over Northwest Bay of Bengal. As anticipated, a cyclonic circulation has appeared over Bay of Bengal, off Odisha coast, with a trough extending northward up to West Bengal. This feature is likely to get organize, become more marked and may turn in to a low pressure area, albeit a feeble one.
This hybrid system, partly over sea and rest over land, will meander over coastal parts of Odisha and adjoining BoB, on 28th and 29thAugust. It is expected to cross coastline and move inland on 30th Aug, covering parts of North Coastal Andhra Pradesh, South Chhattisgarh and North Telangana.
This is unlikely to be an intense weather system, but spread of activity will be large spanning east and central parts together, before shifting to western and northern parts in the 1st week of September.
It is unlikely to cause incessant and torrential activity but moderate intensity rains embedded with intermittent heavy spells are expected over Odisha, Andhra Pradesh, Chhattisgarh, Maharashtra, Madhya Pradesh, Rajasthan and Gujarat. The peripheral and remnant of this low pressure will impact weather conditions over West Bengal, Jharkhand, Bihar, Uttar Pradesh, Telangana, Delhi, Haryana and Uttarakhand.
The low pressure area will have a life span of nearly one week or even more. This system will not cause any flooding, water logging or disruption of routine activities. Rather, the rainfed areas in the core monsoon zone will be the large beneficiaries.
Seasonal rainfall deficiencies over Odisha, Chhattisgarh, East Madhya Pradesh and Vidarbha may shrink and fall below 10% in some of the pockets. Perpetual deficit rainfall being recorded on daily basis may get arrested and possibly, normal or above normal Pan-India rainfall will be achieved for the next one week.
