SIGNIFICANT WEATHER FEATURES

♦ Favourable position of anticyclone in the Bay of Bengal leading to continuous moisture incursion, strong wind convergence in the lower levels and favourable upper level features have caused fairly widespread to widespread rainfall/thunderstorm activity over Northeast and adjoining parts of East India along with isolated very intense rainfall activity . Very severe thunderstorms accompanied with squalls and hailstorms also had been reported from these regions during the week.

♦ Trough/wind discontinuities in the lower levels have caused scattered to fairly widespread rainfall/thunderstorms over parts of Peninsular India and isolated to scattered rainfall/thunderstorm activity over parts of West and Central India, along with isolated intense rainfall activity. Isolated hailstorm activity also had been reported from these regions during the week.

♦ Movement of a Western Disturbance and its induced cyclonic circulation has caused scattered to fairly widespread rainfall/thunderstorm activity over Western Himalayan Region and isolated to scattered rainfall/thunderstorm activity over adjoining plains of northwest India during the week.

Isolated hailstorm activity also had been reported from these regions along with isolated intense rainfall activity over Himachal Pradesh, during the passage of the system.

Heavy Rainfall:

♦ Heavy to Very heavy rainfall had been observed at isolated places over Arunachal Pradesh and Odisha on one day each during the week.

♦ Heavy rainfall had been observed at isolated places over Assam & Meghalaya and Tamil Nadu, Puducherry & Karaikkal on three days each; over Himachal Pradesh, Nagaland, Manipur, Mizoram &

Tripura, Bihar, Odisha, Madhya Maharashtra, Chattisgarh, Kerala & Mahe and South Interior Karnataka on one day each during the week.
