New Delhi: The north-east monsoon, which has been delayed by more than a week, is likely to hit the southern peninsula around 30 October, the India meteorological Department (IMD) said in a bulletin.
With the gradual setting of the north-easterlies along the east coast, the south-west monsoon withdraw from the entire country on Friday. Typically, the onset of the north-east monsoon coincides with the withdrawal of the south-west monsoon.
The north-east monsoon was delayed mainly on account of the formation of the cyclonic storm “kyant ” over the Bay of Bengal which is approaching the coastal districts of Andhra Pradesh and Odisha.
According to IMD, this cyclone has weakened over the last one day and its effect will diminish further.
Light to moderate rainfall will occur over many places of Andhra Pradesh and northern coastal Tamil Nadu and Kerala during the next 72 hours with heavy rainfall at isolated places.
“This rain would be beneficial for transplanting of rice in Tamil Nadu and Kerala as well as the sowing of rabi crops like millets, pulses and oilseeds. Because of the rainfall in the coastal Andhra Pradesh, it is advised not to harvest the standing crops like maize, groundnut and ragi” said N. Chattopadhyay, deputy director general at the agricultural meteorology division of IMD.
The north-east monsoon is particularly important for Tamil Nadu, which receives 48% of its annual rainfall during this season. The southern peninsular region consists of five subdivisions: Tamil Nadu, coastal Andhra Pradesh, Rayalaseema, Kerala and south interior Karnataka.
Last year, the north-east monsoon had wreaked havoc in Tamil Nadu with record rain in the month of the December. Last year, Tamil Nadu received excess rainfall of 53% above the normal from 1 October to 31 December.
Kerala also received 27% excess rainfall during last year’s north-east monsoon.
“North-east monsoon would be normal for Tamil Nadu this year” said S. Balachandran, a scientist at the Area Cyclone Warning Centre, Chennai.
