♦ Last week’s Well Marked Low Pressure Area lay over south Madhya Maharashtra and adjoining south Konkan in the forenoon and over Konkan and neighbourhood in the evening of 15^th October 2020; moving west-northwestwards , it emerged into Eastcentral Arabian Sea and lay centered over Eastcentral Arabian Sea off North Maharashtra coast in the forenoon and over East Central &

adjoining Northeast Arabian Sea off South Gujarat coast in the evening of 16^th ; while moving westwards, it concentrated into a Depressionand lay centred over Eastcentral & adjoining Northeast Arabian Sea at about 380 km south-southwest of Veraval (Saurashtra, Gujarat), 440 km west- northwest of Mumbai and 1600 km east-northeast of Salalah (Oman) on 17^th ;during its course of movement westwards further, it weakened into a Well Marked Low Pressure Area over Westcentral Arabian Sea & neighbourhood in the early morning hours of 19^th October 2020; it has weakened further and lay as a Low Pressure Area over Westcentral Arabian Sea on 20^th;the Low Pressure Area has become less marked; however, its remnant cyclonic circulation lay over Westcentral &

adjoining Southwest Arabian Sea in the lower tropospheric levels on 21^st October 2020. This system has caused fairly widespread to widespread rainfall/thunderstorms along with intense to very intense rainfall activity over coastal and interior parts of Maharashtra in the beginning of the week and isolated to scattered rainfall/thunderstorms along with isolated intense rainfall activity over Gujarat State on one or twodays during the week.

as a Well Marked Low Pressure Area over Westcentral Bay of Bengal & neighbourhood on 21^st October 2020;This system, its associated cyclonic circulation extending upto mid tropospheric levels and a trough fromthe cyclonic circulationassociated with the system across Peninsular India withextension upto mid tropospheric levels have caused fairly widespread to widespread rainfall/thunderstorms along with isolated intense rainfall activity over parts of Peninsular India during the second half of the week.

♦ Circulation features associated with the Low pressure system over the Bay of Bengal which supported moisture incursion into the area have caused scattered to fairly widespread rainfall/thunderstorms along with isolated intense rainfall activity over parts of northeast India during the second half of theweek.

♦ Heavy to very heavy rainfall with extremely heavy falls at isolated places had been occurred over Coastal and South Interior Karnataka onone day each duringthe week.

♦ Heavy to very heavy rainfall at isolated places had been occurred over Madhya Maharashtra on three days; over Konkan & Goa on two days; over Odisha, Marathwada, Telangana and Tamil Nadu, Puducherry & Karaikkal on oneday each during the week.

♦ Heavy rainfall atisolated places had been occurred over Nagaland, Manipur, Mizoram & Tripura on

four days; over Saurashtra & Kutch and Coastal Andhra Pradesh & Yanam on three days each; over Tamil Nadu, Puducherry & Karaikkal, North & South interior Karnataka, Chhattisgarh and Assam &

Meghalaya on two days each; over Andaman & Nicobar islands, Odisha, East Rajasthan, West Madhya Pradesh, Gujarat Region, Rayalaseema and Coastal Karnataka on one day each during the week.

Temperature Scenario:

♦ The highest maximum temperature of 39.1^o C had been recorded at Rajkot (Saurashtra & Kutch) on 15^th October 2020 and at Churu (West Rajasthan) on 20^th October 2020 and the lowest minimum temperature of 12.5^oC had been recorded at Ludhiana (Punjab) on 21^st October 2020 over the plains of the country during theweek.

LEGEND: A few days- 3 days, Many days- 4 to 5 days and Most days- 6 to 7 days during the week.
