As per reports, June to September is the period for the Southwest monsoon and is considered as the main rainy season for the Indian subcontinent.

Over different parts of the country during the monsoon season of 2020, ‘heavy’ to ‘very heavy’ and ‘extremely heavy’ rainfall events occurred. Due to such events, parts of Himachal Pradesh, Maharashtra, Kerala, Uttar Pradesh, Assam, Bihar and Telangana suffered extreme flooding.

Reports further said that in 2020, the National Disaster Response Force (NDRF) had rescued and evacuated 19,241 people and 334 livestock.

Among the states, West Bengal reported the highest 258 deaths due to heavy rains and floods which was followed by Madhya Pradesh and Gujarat, both reporting 190 deaths each.

The Ministry stated that several scientific studies bring out the possible linkage of climate change with the sudden occurrence of rainfall and temperature extremes.

This year, monsoon arrived in Maharashtra and Goa two days in advance of its normal onset date calculated.

The monsoon progressed very quickly over most parts of the country. It covered most of India in only 10 days mainly due to active monsoon circulation and the formation of a low-pressure area over Bay of Bengal, said The India Meteorological Department (IMD).

IMD further added that due to approaching of mid-latitude westerlies winds, the further progress of monsoon over remaining parts of northwest India is likely to be slow.
