The IMD said that dry weather is very likely over most parts of northwest India during next 5 days and moderate thunderstorm with lightning very likely at isolated places over north peninsular India, Central and northeast India during next 12 hours.
As per a few reports, India has received 9 per cent more rainfall than the normal until September 27.
According to IMD, the seasonal cumulative rainfall during 2020’s southwest monsoon season up to September 16 was above LPA by +7%.
Notably, the LPA of rainfall is the rainfall recorded over a particular region for a given interval (like month or season) average over a long period like 30 years, 50 years etc. It acts as a benchmark while forecasting the quantitative rainfall for that region for a specific month or season.
The official rainfall season in the country starts from June 1 and withdraws from the southern peninsula and hence from the entire country only after October 1.
