New Delhi, Thursday, June 21 The southwest monsoon in spite of spoilers like Talim has inched further into remaining parts of Chhattisgarh, Jharkhand, Bihar, some more parts of east Madhya Pradesh and some parts of east Uttar Pradesh.
Notably, the monsoon is due in these parts and more by June 15. Most parts of Gujarat (excluding some parts in north), most of Madhya Pradesh (excluding the Gwalior region) and southwest Rajasthan are usually splashed by monsoon showers.
The Northern Limit of Monsoon (NLM) is now passing through Veraval, Navasari, Malegaon, Betul, Jabalpur, Siddhi, Varanasi, and Gorakhpur. The northern limit of monsoon is an imaginary line that connects places where the monsoon has reached at a given point in time.
The off shore trough along the west coast persists. It is extending from south Konkan to Kerala at mean sea level. This is likely to strengthen and hence active monsoon conditions would prevail during next the twenty four to forty eight hours.
Rain and thundershowers would occur at many places along the west coast over Konkan & Goa, coastal Karnataka and a few places over Kerala and at one or two places over interior peninsular India except Tamil Nadu where it will be mainly dry.
Troughs are places where winds from opposing directions meet (or winds turn) and atmospheric pressure is low while the turbulence caused by such interaction (or turning) leads to rain, thundershowers and storms.
A cyclonic circulation (upper air) over northwest Bay of Bengal and adjoining Gangetic West Bengal and coastal Orissa also persists.
Another upper air cyclonic circulation over east Uttar Pradesh and neighborhood exists. The two weather systems would work in tandem pave the way for further penetration of monsoon into east Uttar Pradesh and some parts of west Uttar Pradesh during the next 3-4 days.
Meanwhile, the would cause rain/thundershowers at many places over Vidarbha, Chhattisgarh, Bihar, Jharkhand, West Bengal, and at few places over east Madhya Pradesh and east Uttar Pradesh.
Moderate rain is also likely over many places over northeast India under the aegis of moisture inflow from the Bay of Bengal. Heavy rainfall is likely at one or two places also.
Plains of northwest India and west Madhya Pradesh would be dominated by strong surface winds, in the range of 25-30 kmph due to a strong pressure gradient in these latitudes. The winds would be mostly hot and dry as the region is being inundated by westerly winds from hotter climes in west Rajasthan and adjoining Pakistan.
The situation will reign for another seventy two hours and no respite from ongoing hot weather conditions is in sight.
