By Friday, the country as a whole had received 85.5 mm rainfall while the normal for this time is 103.8 mm. Northwest India, which is yet to be covered by the monsoon entirely, and southern peninsula have received more than normal rainfall, while central India and east and northeast India have got below normal rainfall till now.
Central India, comprising of parts of Maharashtra, MP, Chhattisgarh, Odisha, Andhra Pradesh, Telangana and UP, have been the driest so far. It has a deficiency of 37 per cent, while north and northeast India, together, have a deficiency of 25 per cent.
In the past one week, the monsoon advanced to cover most of the country, including southern Gujarat, parts of west MP, east UP, Uttarakhand, Himachal Pradesh and J&K.
The only places where the monsoon rains are still awaited are parts of west MP, the entire western Uttar Pradesh, most of Haryana, Delhi, Punjab and east Rajasthan. The Met office said these regions are likely to start getting rainfall by the middle of the coming week.
