New Delhi, Monday, 23 July, After lashing central India for the past four days, monsoon is again looking vigorous, but this time over southwest Rajasthan, northeast Maharashtra and southwest Madhya Pradesh. Four districts of south west Rajasthan, Khargaon, Barwani, Dhar and Jhabua are likely to be affected by heavy showers while three districts of northeast Maharashtra, Dhule, Nandurbar and Jalgaon would also get heavy showers in the next twenty four hours.
The current downpour scenario over these two areas has evolved after the low pressure showed up over the Bay of Bengal and entered the sub-continent from the east coast a few days ago. It has now moved to position itself over southwest Madhya Pradesh. Initially, it was predicted to move westwards but strong southwesterly winds are taking it a little north towards east Rajasthan, north Madhya Pradesh and adjoining Uttar Pradesh, giving a boost to rainfall activity here.
Central India, which is currently witnessing increased rainfall activity and flood like situation in Vidarbha and Telangana, is likely to find respite as rainfall intensity is expected to decrease as the low over south Chhattisgarh has moved on.
The southwesterly winds are strong and pushing the monsoon trough northwards to encourage rainfall activity over Uttar Pradesh, Bihar and Jharkhand.
The western part of monsoon trough is shifting northwards and is likely to be positioned over north of Delhi to bring rain in the capital from 24th evening onwards.
Due to this shift of monsoon trough, Uttarakhand and Himachal Pradesh would also see increased rainfall in the next twenty four to forty eight hours. Rain, heavy at many places and very heavy at a few places in Uttarakhand, is expected after twenty four hours.
Monsoon trough is essentially a region of intensified moisture laden monsoon winds.
Temperatures are rising over the northwest plains. Temperatures are up by one or two degree Celsius above normal. In western Rajasthan, where dry weather is prevailing, temperatures remain in the forties. Prevailing dry weather conditions under the influence of dry westerly winds are causing the temperature rise.
Moist southwesterly winds gushing in by tomorrow evening may reverse the trend.
Along the west coast, the off shore trough extends from Konkan to Kerala coast and is weak. The coast is experiencing moderate rain, which is likely to continue in the next twenty four hours. Rainfall intensity may increase after this due to spike in moisture laden southwesterly winds.
In southern Peninsula, rainfall is not significant though. Scanty rain is possible over Tamil Nadu and interior Karnataka.
