Pre-monsoon Rainfall Scenario (1 March to 5 May, 2021)
2 | P a g due to rain and thundershower activities over many parts of India for many days of the week. A western disturbance lies as a trough in the mid- and upper-tropospheric westerlies with its axis at 5.8 km above mean sea level roughly along longitude 64°E north of latitude 26°N. A trough in the western part runs roughly along longitude 90°E north of latitude 18°N between 3.1 km and 7.6 km above mean sea level.
A cyclonic circulation extends over North Interior Karnataka and the neighborhood at 0.9 km above mean sea level. A cyclonic circulation extends over northern parts of Central Madhya Pradesh and extends up to 1.5 km above mean sea level. An east-west trough crosses the above cyclonic circulation over northern parts of Central Madhya Pradesh to Tripura along Jharkhand and Gangetic West Bengal at 0.9 km above mean sea level.
A trough/wind discontinuity runs from the cyclonic circulation over northern parts of Central Madhya Pradesh up to Marathawada at 0.9 km above mean sea level. A cyclonic circulation lies over the Southeast Arabian Sea and adjacent Maldives area at 0.9 km above mean sea level.
Large scale features as on 6 May, 2021
It will move to Phase 2 from tomorrow and continue in the same phase for the next two days. It will spread eastward and move into phase 4 through phase 3 in the later part of week 1 with an amplitude of less than 1. Thus, the phase and amplitude of the MJO will support an increase in convective activity over the northern Indian Ocean (including the Bay of Bengal). and the Arabian Sea) in Week 1 only.
Due to low/wind disruption over southern peninsular India, light/moderate scattered to fairly widespread rain/thunderstorm is very likely over Kerala & Mahe, Lakshadweep and Coastal & South Interior Karnataka; and isolated rain/thundershowers over the rest of southern peninsular India during the week. Isolated heavy rainfall is also likely over Kerala & Mahe and Coastal & South Interior Karnataka today, 6th and 12th May 2021. Light rainfall/thundershowers are very likely over the rest of the country during the week (Appendix IV).
Rainfall activity is very likely to be above normal above areas except Arunachal Pradesh
Nicobar Island, State of Gujarat, Kerala & Mahe and Lakshadweep; in isolated places over Assam and Meghalaya, Nagaland, Manipur, Mizoram and Tripura, West Bengal &. Due to the likely stormy activity over most of the country, the maximum temperature is very likely to be below normal in most parts of the country except parts of Western Himalayan region, East Coast and Saurashtra and Kutch where they are likely to be near normal or slightly above normal. Therefore, it is not very likely that there will be a heat wave in any part of the country during the next week.
Impact of heat wave and action suggested
Cyclogenesis
CGEPS (MME) shows a low probability of cyclogenesis (10-20%) over the southern Bay of Bengal during the forecast period. The Genesis Potential Parameter (GPP) based on the IMD GFS does not show any potential area for cyclogenesis over the northern Indian Ocean during the forecast period. However, it is seen that the Northern Hemisphere near the equatorial trough is likely to become convectively active over the southern Arabian Sea early in week 2.
Under its influence, a 'low pressure area' is likely to form over central parts of the southern Arabian Sea and there is a 'low' probability of its intensification and cyclogenesis over the same region during the later part of week 2. Considering all the above , it can be concluded that there is a low probability of cyclogenesis over the southern Arabian Sea in the later part of week 2.
Considering all the above, it may be concluded that there is low probability of cyclogenesis over south Arabian Sea during later part of week 2

According to the Reservoir Storage Bulletin of date, the total available live storage in these reservoirs is 15.42 BCM, which is 34% of the total live storage capacity of these reservoirs. The storage during the corresponding period last year was 47% and the average storage of the last ten years during the corresponding period was 31% of the living storage capacity of these reservoirs. The mark-up during the current year is therefore less than the mark-up of last year, but better than the average mark-up of the past ten years during the corresponding period.
