Cyclone threat recedes, onset of monsoon delayed

Cyclone threat to Kerala and Tamil Nadu has receded as the storm in the Arabian Sea is heading for the Oman-Yeman coasts while the one in the Bay of Bengal is heading towards Odisha. As a result, the wind pattern has changed and consequently the onset of the north-east monsoon may be delayed, the weather department has said.

The Indian Meteorological Department has said Cyclone LUBAN over westcentral and adjoining southwest Arabian Sea has moved west­northwestwards and lay centred at 08,30 a.m. on Monday over west central and adjoining southwest Arabian Sea, “

It is very likely to intensify further into a severe cyclonic storm during next 24 hours. It is very likely to move west­northwestwards towards south Oman and Yemen coasts during next five days, the department said in a bulletin.

It further said the well marked low pressure area over southeast Bay of Bengal and adjoining east central Bay of Bengal has concentrated into a depression.It l ay centred at 8.30 a.m. on Monday over east-central Bay of Bengal. It is very likely to intensify further into a deep depression during next 24 hours and into a cyclonic storm during subsequent 24 hours.

“It is very likely to move north-westwards towards Odisha and adjoining north Andhra Pradesh coasts during next 72 hours”, it said.

Due to the intense systems, the wind regime has changed over the Bay of Bengal and adjoining sea areas. As a result, the rainfall activity is very likely to decrease over south peninsular India from Tuesday onwards. Hence the commencement of northeast monsoon rainfall over Tamil Nadu and Puducherry, Kerala and adjoining areas of Andhra Pradesh and Karnataka is not likely to take place as assessed earlier.

Development of favourable conditions for northeast monsoon will be closely monitored and its commencement over Tamil Nadu will be assessed after the life cycle of the cyclonic system over the Bay of Bengal, the weather department said.

It said Port Blair in Andaman and Nicobar witnessed heaviest rains, of 13 cm. in the past 24 hours , followed by Mana Madurai in Tamil Nadu which recorded 12 cm rains.

Thundershowers were observed in most places over Andaman and Nicobar Islands, Kerala and Lakshadweep and many places in Tamil Nadu and Puducherry.
