The India Meteorological Department (IMD) has announced the arrival of south-west monsoon in Mumbai and the Konkan region.
Elaborating further, the IMD said the southwest monsoon had further advanced into the remaining parts of the central Arabian Sea, most parts of Konkan, including Mumbai, some parts of central Maharashtra and by the start of the next week, and was expected to cover most of this region and had made further inroads in Karnataka on Saturday.
For the next 24 hours, in Mumbai, generally cloudy skies with light to moderate rain, with isolated thunderstorms in the city and suburbs can be expected, the IMD said.
Mumbai recorded maximum day temperatures of 30°C and high humidity, at 87 per cent, with intermittent showers and thunderstorms on Saturday.
The weather agency further said that the present conditions were favourable for the further advance of the monsoon into some parts of north Arabian Sea, the rest of Konkan, all of Karnataka and Tamil Nadu, parts of Gujarat, Telangana, Andhra Pradesh, the west central and northwest Bay of Bengal in the next 48 hours.
“Conditions would continue to become favourable for further advance of monsoon into some more parts of north Arabian Sea, Gujarat state, some parts of Marathwada, some more parts of Telangana, Andhra Pradesh, most parts of Bay of Bengal, entire Sub-Himalayan West Bengal and Sikkim, some parts of Odisha, Gangetic West Bengal, Jharkhand and Bihar during subsequent 2-3 days,” theIMD tweeted.
Despite the early monsoon onset in Kerala, its overall movement remains slightly behind schedule over the west coast. As per the normal onset dates based on weather data from 1961 to 2019, the monsoon normally arrives in Mumbai by June 11, usually a day after its onset in Pune. Thereafter, it reaches Ahmednagar by June 12 and Nagpur by June 15.
The IMD announces the start of monsoon when 60 per cent of the state’s accessible weather stations record rainfall of 2.5 mm or more for two consecutive days. The technical parameters for wind field and outgoing longwave radiation must also be met in conjunction with this burst of rainfall activity, the agency informs.
