Updated on December 22, 2015: As reiterated by Skymet Meteorology Division in India, Odisha recorded fairly widespread light to moderate rain during last 24 hours.
In span of 24 hours from 8:30 am on Tuesday, Puri recorded 18 mm of rain, Sambalpur 10 mm, Bhubaneswar 6 mm, Keonjhargarh 3 mm, Chandbali 2 mm, Paradip 2 mm and Jharsuguda 2 mm.
The state has been consecutively receiving scattered light rain for the last few days. The ongoing rain activity can be attributed to the continues confluence of dry and cold northwesterly winds with warm and moist southwesterly winds from the Bay of Bengal.
Neighbouring parts of Chhattisgarh have also received scattered light rain. Capital city of Raipur recorded 9 mm of rain in last 24 hours.
According to Skymet, the weather phenomena will continue to prevail over the region for some more time. Thus, we can expect rain and thundershowers activity to continue over Odisha for another three to four days.
Scattered light rain may also occur over parts of Jharkhand, Chhattisgarh and isolated parts of North Coastal Andhra Pradesh.
Updated on December 21, 2015: Odisha continues to witness scattered light rain during the last 24 to 48 hours. Isolated showers were also observed over few pockets of North Coastal Andhra Pradesh.
In span of 24 hours from 8:30 am on Sunday, Keonjhargarh recorded 6.2 mm of rain, Sambalpur 4 mm and Angul 2.6 mm.
According to Skymet Meteorology Division in India, dry and cold northwesterly winds from northern region continue to confluence with warm and moist southwesterly winds from the Bay of Bengal, leading to rain over parts of East India.
Wind pattern is not expected change during next 24 hours as well. With this, isolated to scattered light showers are likely over parts of Odisha, Chhattisgarh and North Coastal Andhra Pradesh during next one or two days.
Updated on December 18, 2015: East India has been witnessing the first spell of winter rains for the past two to three days.
In span of 24 hours from 8:30 am on Thursday, fairly widespread light to moderate rainfall was observed over Chhattisgarh, Jharkhand, Odisha and Gangetic West Bengal.
According to Skymet Meteorology Division in India, scattered light rain will continue for the next 24 hours and reducing thereafter.
This rain activity has been on account of the conversion of dry and cold winds blowing from North India with the warm and moist winds from Bay of Bengal. However, southwesterly winds from Bay of Bengal will be replaced with northwesterly winds now and thus seizing the rainfall.
Updated on December 16, 2015: Scattered light to moderate rain is expected over Odisha, Chhattisgarh and few parts of West Bengal and Andhra Pradesh. However, intensity of rain will be more over parts of Odisha.
According to Skymet Meteorology Division in India, dry and cold winds blowing from North India are converging with the warm and humid winds from South India for the last few days. This phenomena has become more marked and turned into a trough extending from West Bengal up to Chhattisgarh across Odisha.
The rains are likely to continue for next 48 hours with major activity expected on December 17 and reducing thereafter.
Inw ake of the fresh rainfall activity, temperatures will also reduce across the respective states.
Updated on December 12, 2015: Scattered light rain is expected over several parts of South Chhattisgarh, Odisha and Vidarbha region of Maharashtra during next 24 to 48 hours. Adjoining areas of Telangana may also receive isolated light showers. However, rains will be patchy in nature with light intensity and will not be widespread.
According to Skymet Meteorology Division in India, the unseasonal rain activity will be due to the conversion of dry and cold winds blowing from North India with the warm and humid winds from South India.
In wake of the weather activity, minimum temperatures will rise by 2-3 degrees while maximum temperatures will witness a marginal drop.
Normally, rain do not occur over these parts of the country during this season. Odisha sometimes gets rain during this time but that too on account of any weather system emerging in Bay of Bengal.
It is a very rare phenomena for Chhattisgarh and Vidarbha to witness rain during this season that generally witness dry weather conditions by now. But sometimes due to this type of wind conversion, light rain do occur over both the states.
The region has been dry for quite a long time now. Hence, these rainfall will be very useful for restoring moisture levels in soil, ahead of sowing season of Rabi crop.
