“Under the influence of the cyclonic circulation over Myanmar & adjoining Eastcentral Bay of Bengal, a low pressure area has formed over Northeast and adjoining Eastcentral Bay of Bengal. It is likely to become well-marked low pressure area and move northwestwards towards north Odisha & adjoining West Bengal coasts during next 48 hours,” the weather agency said in its morning bulletin.

The cyclonic circulation over north Coastal Karnataka and neighbourhood has also intensified into a low pressure area over Eastcentral Arabian Sea off south Konkan-Goa coasts. It is likely to become Well Marked Low Pressure Area over the same area and gradually move west-northwestwards during next 24 hours, it added.

With the low pressure over Bay of Bengal expected to become well marked and move northwestwards towards north Odisha & adjoining West Bengal coasts, Odisha is likely to experience heavy downpour during the next few days.

The IMD has forecast light/moderate fairly widespread to widespread rainfall/thunderstorm and lightning with isolated heavy rainfall over Odisha during September 29 to October 1. Isolated very heavy rainfall may also occur over Odisha on October 1 and 2.

According to the weather agency, moderate rain/thundershower with lightning and one or two spells of intense rain may occur at some places in Dhenkanal, Cuttack and Mayurbhanj in three hours.

It has warned of waterlogging in low-lying areas, occasional poor visibility and traffic disruption in urban areas.

Yellow warning of light to moderate rain with lightning has been issued for some parts of Sundargarh, Deogarh, Keonjhar, Angul, Jajpur, Bhadrak, Kendrapada, Jagatsinghpur, Khurda (including Bhubaneswar), Ganjam, Gajapati, Nayagarh and Puri districts. People have been advised to keep a watch on the weather and accordingly move to safer places to protect themselves from lightning strikes.

Notably, the IMD in its midday bulletin had issued no heavy rain warning for the day. It had forecast light to moderate rain or thundershower at many places in North Odisha and at a few places in South Odisha till 8.30 am on September 17 and sounded yellow warning of heavy rain from September 18.

This system is expected to move across Odisha and Chhattisgarh during next 2 days, the India Meteorological Department (IMD) informed.

The weather agency further said that the southwest monsoon has also been vigorous over the state, leading to widespread light to moderate rain/thundershower with heavy to very heavy at a few places and isolated extremely heavy rain in Balangir and Rayagada in the past 24 hours. “With intense spells of rain continuing during the next 24 hours, flood-like situation may occur in interior pockets with the likely increase in the water level of rivers in the state,” IMD, Bhubaneswar, scientist Umashankar Das told a media briefing.

He added that the intensity of rain might gradually decrease from September 15.

While one district received excess rain and 25 are in the normal category, only 4 districts are deficient. “Nabarangpur, Kalahandi, Balangir, Rayagada, which had recorded a shortfall, have been receiving heavy rain,” Das said, adding that intensity of rain might increase again from September 19.

The IMD has forecast heavy rainfall at one or two places in Bargarh, Jharsuguda, Sundargarh, Keonjhar, Mayurbhanj, Sambalpur, Deogarh, Angul, Cuttack and Dhenkanal districts.

There is no heavy rain warning for Odisha thereafter as the cyclonic circulation is expected to move west-northwestwards and lie over central parts of Madhya Pradesh during September 8-10.

Under its influence, light/moderate fairly widespread to widespread rainfall/thunderstorm & lightning with isolated heavy rainfall activity is likely over Odisha from September 2-5, the India Meteorological Department said on Friday.

Odisha has been witnessing a weak monsoon, leading to a rise in the humidity level, which the Met office said would continue for another 48 hours. “Due to subdued monsoon, the day temperature in coastal Odisha was recorded at 3 to 4 degrees above normal with humidity at 60%,” it said.

The weather agency has forecast thunderstorm with lightning at one or two places in Jharsuguda, Sundargarh, Sambalpur, Deogarh, Angul, Dhenkanal, Jajpur, Balasore, Bhadrak, Bargarh, Nuapada, Kalahandi, Nabarangpur, Balangir, Sonepur, Malkangiri, Koraput, Kandhamal, Boudh, Ganjam, Gajapati, Rayagada with light to moderate rain at a few places over next 12 hours. While similar warning continues for next two days, heavy rain may lash the state for four days from September 2 with little change in the weather during the subsequent two days, it added.

Centre for Environment and Climate (CEC) at SOA University here had also forecast formation of a cyclonic circulation over east central and adjoining north-east Bay of Bengal off the Myanmar-Bangladesh coast on Wednesday with movement towards north-west Bay on September 2. “A low pressure area is likely to form in the afternoon of September 3 or morning of September 4 over northwest Bay of Bengal and the system might intensify into a depression on September 5,” a CEC bulletin said.

While light to moderate rainfall may continue from September 2, widespread precipitation with heavy to very heavy rainfall is likely at a few places between September 4 and 7 over the state. There is also a probability of very heavy rain over coastal, north and western Odisha and widespread rainfall with heavy fall at some places in south Odisha. Extremely heavy rain is likely to occur on September 5 and 6 and the spell of rainfall in the ensuing week could offset the deficit rainfall in some of the districts, it added.

Notably, Odisha has recorded 784.9 mm rainfall against its normal value of 922.3 mm till September 1 this monsoon season. While one district has received excess rain, 11 are deficient and the rest 18 districts in the normal category.

Thunderstorm with lightning is likely at one or two places in Balasore, Bhadrak, Jajpur, Kendrapada, Cuttack, Jagatsinghpur, Puri, Khurda, Nayagarh, Ganjam, Gajapati, Malkangiri, Koraput, Nabarangpur, Kalahandi, Kandhamal, Rayagada, Sundargarh, Keonjhar and Mayurbhanj districts till 8.30 on Friday.
