Fresh Low Pressure Likely: Active Monsoon Conditions Over East And Central Parts

In quick succession, another low-pressure area is likely to form over the Bay of Bengal.  A feeble cyclonic circulation is marked over the coastline of Bangladesh and Myanmar, between Chittagong and Akyab, and adjoining Northeast Bay of Bengal (BoB).  It is likely to become more marked and shift over extreme north BoB during next 24hour.  A  weak low pressure area is expected to come up over Northwest BoB, off Odisha coast, in the subsequent 24hr. In case of limited support from the environment, around the area of influence, it may not grow significantly. Still, the weather system will keep the monsoon active over the eastern and central parts for this week.

The remnant of freak storm which formed earlier over northwest Bay of Bengal on 19^thAug,  is still marked as a formidable depression over Madhya Pradesh. There have been incessant and extremely heavy rains over most parts of Madhya Pradesh, from Jabalpur to Bhopal and Guna to Pachmarhi, in the past 24hr.  All is not yet over and done.  Extremely heavy rainfall is expected for the next 24hr over southwest Madhya Pradesh covering Indore, Ujjain, Bhopal, Dhar, Khargone, Khandwa, Ratlam and Neemuch.  Subsequently, heavy rainfall belt will shift to Rajasthan and Gujarat.

Fresh low pressure area will keep the monsoon active over the east and central parts, in a staggered way commencing 23^rdAug.  Scattered rain and thundershowers are likely across states of Bihar, Jharkhand, West Bengal, Odisha and Chhattisgarh on 23^rd&24^th Aug.  On 25^th and 26^th,  Odisha, Chhattisgarh and East Madhya Pradesh is expected to have fairly widespread weather activity. Subsequently, the rain belt will travel across entire Madhya Pradesh and East Rajasthan  on 27^th and 28^th Aug. The far end of the system will affect even Telangana and Vidarbha also, between 27^th and 29^thAug.

This low pressure will be rather weak during its span of 4-5 days.  Also, the system will not reach Gujarat and West Rajasthan. Though, a little early to preempt, the fag end stage of the system may take the monsoon trough, well north of its normal position, very close to the foothills.  Rainfall activity may reduce during the 1^st week of September.
