The low-pressure area over Jharkhand and adjoining Bihar and West Bengal persists and is expected to move in a north-easterly direction. The system will now start affecting Sub-Himalayan West Bengal, Sikkim, Meghalaya, Assam, and some parts of Bihar. Rainfall intensity will gradually decrease from East India. However, scattered rain will continue over Bihar, Jharkhand, West Bengal, and Odisha for another 48 hours thereafter decreasing gradually.
Updated on September 21, 2015 12:30 PM (IST): Low pressure area over Bay of Bengal to give rain over East India
The low pressure area that was lying over Odisha and Bay of Bengal has now moved on towards Jharkhand and Bihar. Chhattisgarh, along with Bihar and West Bengal has received good rains in last 24 hours due to this weather system. Places to have received rain in past 24 hours include Bihar: Bhagalpur 14 mm, Gaya 32 mm, Patna 11, Purnea 13 mm, Chhattisgarh: Ambikapur 20 mm, Durg 32 mm, Pendra 89 mm, Raipur 44 mm, West Bengal: Bankura 31 mm, Darjeeling 104 mm, Kolkata 16 mm and Malda 21 mm.
The system is likely to persist over these areas for another 24 hours after which it will shift towards Northeast India and give moderate rainfall over North Bihar, West Bengal and Sikkim.
Updated on September 20, 2015 12:11 PM (IST): Low pressure area over Bay of Bengal likely to intensify into well-marked low
The low pressure area is currently present over west central Bay of Bengal off Odisha coast. The system is expected to intensify further into a well-marked low and will continue to move in the north-westerly direction.
Parts of Odisha, Gangetic West Bengal, Jharkhand, Bihar, and North Chhattisgarh are likely to receive fairly widespread rain and thundershowers due to this system during next 48 hours. Scattered rainfall is likely over places in East Uttar Pradesh also.
One or two places may receive heavy rainfall too. By September 22 or 23, the system is likely to give heavy to very heavy rainfall over North Bihar and adjoining areas.
Updated on September 19, 2015 11:14 AM (IST): Cyclonic circulation in Bay of Bengal intensifies into low pressure area
The fresh cyclonic circulation in the Bay of Bengal has intensified into a low pressure area and is in the process of getting more organised.
The system is presently marked over northwest and adjoining east-central Bay of Bengal, off the West Bengal and Odisha coast.
With this, fairly widespread light to moderate rain and thundershowers are expected over coastal areas of Odisha and West Bengal.
According to Skymet Meteorology Division in India, the system will move in a northwest direction and is expected to move inland during next 48 hours. Due to its movement, rain belt will shift further to cover more parts of East India including Bihar, Jharkhand, parts of Chhattisgarh and East Uttar Pradesh.
Updated on September 18, 2015 05:54 PM (IST): Fresh system comes up in the Bay of Bengal, heavy rain expected in East India
Retreating Monsoon statistically experiences more Monsoon systems forming in the Bay of Bengal. According to weather models at Skymet, a second weather system (cyclonic circulation) has formed in quick succession and was brewing in the Northeast Bay of Bengal and Myanmar coast.
Now the system has shifted to Eastcentral Bay of Bengal. Under its influence a low pressure area has formed, which is likely to get more organized and move inland in next 48 hours. Unlike the last system which had taken a westward track across Central parts of the country, the new system will have more of a North-northwest direction.
It is likely to affect Odisha, West Bengal, East Uttar Pradesh, Bihar, Jharkhand and Northeast India. The system will have a span of one week and will affect coastal parts of Odisha and Bengal initially. Sub Himalayan West Bengal and the foothills of Bihar are likely to receive some very good rains in next 2 to 3 days.
Rainfall in East Uttar Pradesh and Bihar at the moment is deficient by 45% and 28%, respectively. This spell of rain is certainly going to bring some relief to the region by pulling down the deficiency by some extent.
