With the deep depression over the Bay of Bengal making landfall near Odisha’s Puri, the state government on Monday geared up for relief and rescue operations in the districts likely to be affected by the weather system.
A deep depression is a more intense stage of a low-pressure system and typically precedes the formation of a cyclonic storm, according to the IMD.
"The landfall process for any system, whether a depression or a cyclone, takes time. The current system made landfall between 10.30 am and 11.30 am with wind speeds between 55 km/hour and 65 km/hour," said Manorama Mohanty, Director of the Regional Meteorological Centre in Bhubaneswar.
It is very likely to move further northwestwards across interior Odisha, maintaining its intensity of deep depression till evening, and weaken gradually into a depression by midnight of Monday, the IMD said in a bulletin.
The weather office has issued a 'red alert’ (take action) of heavy to very heavy rainfall (7-20 cm) till 8.30 am of Tuesday for 10 districts – Ganajam, Kadhamal, Nayagarh, Khurda, Bolangir, Boudh, Malkangiri, Koraput, Nawarangpur and Puri.
Heavy rain has also been forecast at isolated places in the districts of Cuttack, Angul, Dhenkanal, Jagatsinghpur, Kendrapada, Sonepur during the period.
