Due to dry westerly winds and absence of thunderstorms and rainfall, heatwave to severe heatwave conditions prevailed in some parts of Bihar; in some parts of Gangetic West Bengal and in isolated areas over Sub-Himalayan West Bengal and Sikkim during May 31 - June 7, 2023. Heatwave conditions were also observed in isolated areas over coastal Andhra Pradesh and Telangana on June 7.
No heat wave was observed over north and central India during the week and this was again due to movement of 2 active western disturbances (June 1-5 and June 3-7) across north India which had caused fairly widespread to widespread rainfall/thunderstorm activity over western Himalayan region in two to three days along with isolated to scattered rainfall/thunderstorm over the area. 3 | P a g e remaining days of the week; passage of the systems along with lower tropospheric cyclonic circulations over the plains of northwest India supported by moisture intrusion over the areas had caused scattered to fairly widespread rain/thunderstorm activity over Punjab, Haryana, Chandigarh & Delhi and West Rajasthan in two to three days with isolated rain/thunderstorm activity over the same areas on the remaining days of the week, whereas isolated rainfall activity had occurred over East Rajasthan on most days, over Madhya Pradesh and West Uttar Pradesh on many days and over East Uttar Pradesh on three to four days of the week; Isolated hail activity had also been reported over parts of northwest India and adjoining areas of Madhya Pradesh on a few days of the week, whereas thundershowers had been reported over Uttarakhand on a single day; isolated heavy rainfall had also been reported over Himachal Pradesh and West Madhya Pradesh in one or two days whereas isolated heavy to very heavy rainfall had been reported over Uttarakhand in a single day along with.

Analysis of the weekly total rainfall distribution during the week ending 7 June 2023 and the rainfall scenario of the monsoon season (1 - 7 June 2023): It shows for the country as a whole both the weekly and seasonal cumulative All India rainfall in % deviating of its the long-term average (LPA) until June 7, 2023 was -57%, over the south of the peninsula -63%, in central India -71% and in northwestern India +69. Details of the rainfall distribution over the four broad geographical regions of India are given in Table 1 and the weekly and seasonal meteorological rainfall are given in Appendix II and III respectively.
