The eastern end of the monsoon trough is likely to shift further southwards due to formation of a low-pressure area over west central Bay of Bengal off Andhra Pradesh coast by around tomorrow. Heavy to very heavy rains are likely over Odisha, coastal Andhra Pradesh and Yanam on Sunday; Telangana on September 13 and 14 and Gujarat on September 16. Under the influence of these favourable conditions, widespread rain with isolated heavy rain, thunderstorm and lightning is very likely over west peninsular India during the next 4-5 days. In September, there is 23.5% deficiency over the country with 41.5% deficiency over northwest India, 22.5% deficiency over east and northeast India, 41.4% deficiency over central India and 50.7% excess over south peninsula. But this year IMD’s extended range forecast shows extensive and heavy rains along the west coast between September 11 and 24 and then until October 1 over several parts of central India.
