Soaring clouds (in green) over East, North-West and West India on Tuesday have pushed away heat wave conditions away as twin low-pressure areas popped up over west and east of the country, intensifying monsoon.

Twin low-pressure areas to the west and east of the country have sent the monsoon roaring to activity for a second time after onset phase earlier in May. This lead to its advance of the northern limit on a second consecutive day on Tuesday to Gujarat; remaining parts of Vidarbha and Odisha; most parts of Chhattisgarh; and more parts of Madhya Pradesh.
The ‘low’s popped up simultaneously over eastern parts of Gujarat in the west and south-west Bangaldesh and adjoining West Bengal on Tuesday. While the first may move further to north towards Rajasthan and may move away to Pakistan, the second one will move entirely over Indian territory and may intensify as a likely depression into North-West India.
Third system in offing?
This apart, numerical model predictions by India Meteorological Department (IMD) appear to signal formation of a follow-up low-pressure area over plains of West Bengal in next 10 days and subsequent intensification the very next day as a depression over plains of West Bengal, Odisha and adjoining north coastal Andhra Pradesh, cranking up another wave of heavy rainfall.
Separately, on Tuesday, the monsoon also announced arrival over parts of Jharkhand and Bihar; entire plains and remaining parts of hills of West Bengal, the IMD said rounding up its activity on an eventful day. Heavy to very heavy rainfall with isolated extremely heavy rainfall fell over Saurashtra and Kutch during the 24 hours ending on Tuesday morning.
Extremely heavy rain
Heavy to very heavy rainfall with isolated extremely heavy rainfall was recorded over the ghat areas of Tamil Nadu while it was heavy to very heavy rain over an already rain-battered Coastal and South Interior Karnataka and Kerala during this period. Northern limit of monsoon passed through Deesa, Indore, Panchmarhi, Mandla, Ambikapur, Hazaribagh and Supaul on Tuesday.
The IMD said conditions are favourable for its further advance over remaining parts of Gujarat, Chhattisgarh, Jharkhand and Bihar; some more parts of Madhya Pradesh; and some parts of Rajasthan and East Uttar Pradesh to mark its entry into North-West India during next two days. Helping this advance are low-pressure areas over plains of West Bengal and Gujarat.
“Well-marked low’
The IMD has put the latter on a watch for movement to west-north-west to place it entirely over plains of West Bengal and become ‘well-marked ‘ over Indian territory, as alluded to in these columns during past few days.
Two other weather systems present in the background on Tuesday included a trough that ran away from the ‘low’ over eastern Gujarat towards Jharkhand across Madhya Pradesh and north Chhattisgarh, funnelling in lots of moisture from the Arabian Sea. The counterpart ‘low’ over east India merely helped saturate the scenario with additional moisture from Bay of Bengal.
The other background system is an incoming western disturbance with its axis running across Sri Ganganagr in West Rajasthan and entirely within Indian territory and within close proximity with ‘low’ over east Gujarat that prepares to move further north.
