{{/usCountry}}“Normally, 5-6 depressions form in monsoon but this year we have had only well marked low pressure areas this year. This deep depression will weaken during next 12 hours. The depression will move west-northwestwards and reach west Madhya Pradesh and adjoining Rajasthan region. But a trough will form which will get a moisture feed from Arabian Sea which is why we are likely to experience thundershowers and rain around September 16,” said Sunitha Devi, in charge of cyclones at IMD.
Normally, monsoon starts withdrawing from northwest India around September 17 but IMD’s extended range forecast shows widespread rainfall till September 30.
