SIGNIFICANT WEATHER FEATURES

♦ A cyclonic circulation extending upto mid tropospheric levels lay over Southeast and adjoining Eastcentral Arabian Sea in the beginning of the week; under its influence , a Low Pressure Area has formed over Southeast

& adjoining Eastcentral Arabian Sea on 6^th and it lay over Eastcentral Arabian Sea off Karnataka coast on 7^th; this Low pressure area has merged with an off-shore trough formed along the west coast and lay extending from north Maharashtra coast to Lakshadweep area on 8^th; the off shore trough continued to persist along the west coast and lay extending from south Maharashtra coast to north Kerala coast towards the end of the week; these systems, the cyclonic circulation associated with the Low pressure area which persisted till the end of the week and an east–west shear zone which lay extending across South Peninsula in the lower levels have caused fairly widespread to widespread rainfall/thunderstorms along with intense to very intense rainfall activity over south Peninsular India, Lakshadweep area and coastal and interior parts of Maharashtra during the week.

♦ The eastern end of the monsoon trough lay north of its normal position, close to the foot hills of Himalayas;

this feature along with presence of circulations in the lower levels have caused fairly widespread to widespread rainfall/thunderstorms along with intense to very intense rainfall activity over northeast India and adjoining parts of east India during the week.

♦ Movement of a trough in mid and upper tropospheric westerlies, circulations and troughs in the lower and middle levels have caused scattered to fairly widespread rainfall along with isolated intense rainfall activity over Western Himalayan Region and adjoining plains of northwest and Central India during the week.

♦ Heavy to very heavy rainfall with extremely heavy rainfall at isolated places had been occurred over Assam &

Meghalaya, Sub Himalayan West Bengal & Sikkim and Coastal Karnataka on one day each during the week.

♦ Heavy to very heavy rainfall had been occurred at isolated places over Tamil Nadu, Puducherry & Karaikkal on three days; over Assam & Meghalaya, South Interior Karnataka and Kerala & Mahe on two days each; over Sub Himalayan West Bengal & Sikkim, East & West Rajasthan, West Madhya Pradesh, Madhya Maharashtra, Chhattisgarh and Coastal Karnataka on one day each during the week.
