SIGNIFICANTWEATHERFEATURES

♦Last week’s Low Pressure Area over Southeast Bay of Bengal and adjoining Andaman Sea lay as a Well Marked Low Pressure area over Southeast Bay of Bengal in the early morning hours of 2^nd December 2021; moving west- northwestwards, it concentrated into a Depression in the evening of the same day and lay over Southeast Bay of Bengal at a distance of about 960 km south-southeast of Vishakhapatnam (Andhra Pradesh) and 1020 km south- southeast of Gopalpur (Odisha);then it moved west-nothwestwards initially and then northwestwards and intensified into a Deep Depression in the early morning of the next day and lay over Westcentral and adjoining South Bay of Bengal , about 580 km south-southeast of Vishakhapatnam (Andhra Pradesh) and 670 km south-southeast of Gopalpur (Odisha); then moving north-northwestwards, it intensified into Cyclonic Storm ‘JAWAD’ (Pronounced as JOWAD) around noon of the same day and lay centered at 1130 hrs IST of 3^rd December 2021, over Westcentral of Bengal, about 420 km south-southeast of Vishakhapatnam (Andhra Pradesh), 530 km south-southeast of Gopalpur (Odisha) and 650 km south-southwest of Paradip (Odisha); maintaining the intensity of Cyclonic Storm, it moved north- northwestwards for some time and then northwards but weakened into a Deep Depression in the evening of the next day and lay centered at 1730 hrs IST of 04th December 2021, over Westcentral Bay of Bengal, about 180 km east- southeast of Vishakhapatnam (Andhra Pradesh), 260 km south of Gopalpur (Odisha), 330 km south-southwest of Puri (Odisha) and 420 km south-southwest of Paradip (Odisha); then moving north-northeastwards, it lay centered at 0830 hrs IST of 05th December 2021, over Northwest and adjoining Westcentral Bay of Bengal, about 270 km east-northeast of Vishakhapatnam (Andhra Pradesh), 90 km east-southeast of Gopalpur (Odisha), 120 km south-southwest of Puri (Odisha) and 210 km south-southwest of Paradip (Odisha); it moved north-northeastwards further and weakened into a Depression in the afternoon of the same day and lay centered at 1430 hrs IST of 05th December 2021, over Northwest Bay of Bengal close to Odisha coast, about 50 km southeast of Puri (Odisha), 100 km south-southwest of Paradip (Odisha), 130 km east-northeast of Gopalpur (Odisha), and 370 km north-northeast of Vishakhapatnam (Andhra Pradesh); it moved northeastwards further and weakened into Well Marked Low Pressure Area in the early morning of 06th December 2021 and further weakened into a Low Pressure Area in the morning of the same day over Northwest Bay of Bengal and adjoining West Bengal and Bangladesh coasts; the Low Pressure Area has become less marked;

however, its remnant cyclonic circulation lay over Northwest Bay of Bengal and adjoining West Bengal-Bangladesh coasts with vertical extension upto mid tropospheric levels in the evening of 6^th ; it lay over West Bengal-Bangladesh coasts & adjoining Northwest Bay of Bengal in the lower tropospheric levels on 7^th and has become less marked on 8th December 2021; eventhough this system moved west-northwestward/northwestwards initially and attained cyclone intensity, it recurved afterwards and weakened before coming close to the coast hence has not caused adverse weather associated with cyclones over Indian region; also the system has not made land fall but came very close to Odisha coast during the stage of Depression in the afternoon of 4^th December, before tracking northeastwards and weakening further; however, under the influence of this system, fairly widespread to widespread rainfall/thunderstorm activity had been reported over Odisha during 4-6 December, over Gangetic West Bengal during 5-7 December and over Nagaland , Manipur, Mizoram & Tripura during 6-8 December 2021;it has also caused heavy to very heavy rainfall over Odisha on two to three days and over Gangetic West Bengal on one day during the week; in its initial stages, it has also caused widespread rain/thunderstorm activity over Andaman& Nicobar Islands along with heavy rainfall
