The India Meteorological Department (IMD) has predicted extremely heavy rainfall in and around Maharashtra’s Palghar over the next 24 hours. Isolated heavy to very heavy rain could also lash parts of Mumbai, Raigad and Ratnagiri, said the weather department.
Head of the IMD’s Weather Forecasting Division in Pune, Dr Anupam Kashyapi told India Today, “The formation of low-pressure systems one after another is giving a very heavy spell of rain in northern Maharashtra, northwest Maharashtra as well as Ratnagiri and Raigad districts.”
Parts of Marathwada also received heavy rains in isolated places, Dr Kashyapi added. He also said that ghats in Nashik district are also likely to witness heavy downpours over the next 24-48 hours.
On Sunday, the IMD issued an orange alert for Palghar predicting extremely heavy to very heavy rain till September 15. A yellow alert was also issued for Mumbai by the weather department.
Northern parts of the Konkan region are also likely to witness isolated heavy to very heavy rainfall.
Heavy rainfall means 6.5 to 11.4 cms in 24 hours. At the same time, 11.5 to 20.4 cms in 24 hours is termed as very heavy rain, whereas more than 20.5 cms is referred to as extremely heavy rainfall.

Another low-pressure area formed over the Bay of Bengal brought extremely heavy rains over parts of Odisha and Chhattisgarh on Monday as per the IMD’s earlier prediction.
The deep depression over interior Odisha and another low-pressure area over south Gujarat are most likely to result in heavy spells of rain at isolated places in central and north Maharashtra.

Explaining further, Dr Anupam Kashyapi said southern Maharashtra will also be affected but there will be less rain in this area compared to some other parts of the state.
As the low-pressure system over Odisha moves west-northwest, westerly winds coming from the Arabian Sea will get stronger, resulting in widespread rain. This means that over 76 per cent of the area in the Konkan and Sahyadri ranges will witness heavy rain over the next four-five days.
However, rainfall is expected to recede drastically in Maharashtra after September 15.
