A low pressure area formed over North Bay of Bengal and adjoining Gangetic West Bengal and Bangladesh coast is set to trigger more showers over northern districts of the State.
The system is likely to move in a west-north-westerly direction and pass through West Bengal towards Jharkhand, the weather office said.
Under its impact, rain and thundershower would occur at most places over northern State and heavy to very heavy showers are expected at one or two places during the next 48 hours.
The low pressure caused rains in Balasore, Bhadrak and Mayurbhanj districts. The Met office said Balasore received 84 mm rain followed by 80 mm rain in Chandbali.
Baripada also received over 40 mm rain during the day.
Director, India Meteorological Department, Odisha, S C Sahu, said the system, while passing through West Bengal and Jharkhand, may cause more rains in the next 24 hours after which the showers will decline.
The low pressure will lead to surface wind speed reaching a speed of 40-50 km per hour along and off the Odisha Coast. Fishermen have been advised not to venture into the sea.
