According to weather predictions, widespread rainfall with isolated heavy showers is expected along the west coast due to strengthening of westerly winds and off-shore trough along west coast towards end of month. Rainfall is said to be “near normal” in the remaining parts of the country outside northeastern states and extreme southern parts of southern Peninsular India.
The India Meteorological Department (IMD) has said in its two-week forecast that monsoon progress is likely to pick up between June 27 and June 30 and advance to most parts of northwest India outside west Rajasthan.
Other phenomena behind rainfall across India
In the eastern region, a cyclonic circulation over Gangetic West Bengal and neighbouring areas is causing widespread rainfall. Heavy to very heavy rain is expected in Bihar, Jharkhand, West Bengal, Sikkim and north Odisha during the next two-three days.
A cyclonic circulation is also lying over east Uttar Pradesh and its neighbourhood, raising possibility of heavy to very heavy downpour over east Uttar Pradesh during the next two-three days. Uttarakhand will also see heavy to very heavy rains due to a western disturbance that is running from north Jammu & Kashmir to northeast Arabian Sea.
An offshore trough (line of low pressure), running from south Gujarat coast to north Kerala coast, will cause rains over Konkan, Goa, Madhya Maharashtra Karnataka, Kerala and Mahe.
Mere heavy to very heavy rainfall (70-200 mm) is likely to occur at one or two places.
