Bhubaneswar: With heavy rain triggered by depression lashing several parts of Odisha, the government on Tuesday stepped up preparedness as the system over the Bay of Bengal is likely to intensify into a deep depression soon.
The system is set to cross the north Andhra Pradesh-south Odisha coast between Visakhapatnam and Gopalpur between the night of September 23 and the early hours of September 24.
As part of the arrangements, 33 Odisha Disaster Rapid Action Force (ODRAF) teams have been deployed or kept in reserve in view of the weather system.
Of the 33 ODRAF teams, 24 have been deployed in vulnerable districts, including six each in Ganjam and Koraput, three each in Gajapati, Malkangiri and Rayagada, two in Kalahandi and one in Balangir. Nine teams have been kept in reserve at the ODRAF unit of the OSAP 8th Battalion in Chhatrapur in Ganjam district.
The India Meteorological Department (IMD) said the depression is likely to move west-north-westwards and intensify into a deep depression over the west-central and adjoining northwest Bay of Bengal within the next 12 hours.
The system is likely to continue moving west-north-westwards and cross the north Andhra Pradesh-south Odisha coast between Visakhapatnam and Gopalpur as a deep depression between the night of September 23 and the early hours of September 24.
The weather system is expected to bring heavy rainfall to several parts of Odisha. The IMD has forecast light to moderate rainfall at many places in the state on September 22, with heavy to very heavy rainfall at isolated places.
On September 23 and 24, most parts of South Odisha are likely to receive light to moderate rainfall, while heavy to very heavy rainfall is expected at some places and extremely heavy rainfall at isolated locations.

A red warning has also been issued for Kalahandi, Nabarangpur, Koraput and Malkangiri for September 24 and 25.
