A cyclonic circulation extending up to 0.9 km above sea level is over southern parts of Assam and surrounding areas. Thus, the MJO will support improvement in convective activity over the Bay of Bengal (BoB) in week 1. Sea Surface Temperatures (SSTs) data for the week ending May 10 has cooled further compared to two weeks ago, but remained warmer than the average in parts of the eastern and far western equatorial Pacific.
Much of the central tropical Pacific SSTs are close to average for this time of year. The latest values of the three major NINO indices in the tropical Pacific for the week ending May 10 were: NINO3 +0.2 °C, NINO3.4 +0.2 °C and NINO4 +0.2 °C . The latest MMCFS forecast indicates that these conditions are likely to persist throughout the forecast period. On the week's cyclone forecast and the advance of the SW Monsoon, the well-marked low-pressure area over the southeastern Bay of Bengal and its surroundings is very likely to concentrate into a depression over the central parts of the southern Bay of Bengal will intensify into a cyclonic storm in the same region by May 16 evening.
It is very likely that it will initially move northwestward until May 17 and then again turn north-northeastward towards the northern Bay of Bengal between May 18 and 19. Conditions are likely to become favorable for the advance of the Southwest Monsoon into some parts of the southeastern Bay of Bengal, the Andaman Sea and the Andaman and Nicobar Islands around May 16, 2020. About other synoptic system/wind pattern forecast: Due to coalescence of winds at lower tropospheric levels and supportive features of upper atmosphere are likely to persist, fairly widespread rain/thundershowers very likely over Northeast India and Sub-Himalayan West Bengal and Sikkim and isolated to spread across the rest of eastern India over the next two days.
Storms accompanied by lightning, hail and strong winds (30-40 km/h) in isolated places are also likely in these regions during the same period. Cumulative rainfall for week 1: Heavy rainfall likely over Andaman and Nicober Islands, parts of eastern India and northeastern Adj states and central parts of peninsular and west coast India during week 1. Areas likely to experience heavy rainfall during week 1 were also plotted on the IMD ERF precipitation forecast anomaly map in Appendix III (Also, Ref Appendix IV for today's subdivision precipitation and Appendix V for week 1 cumulative prepared by MME of GFS model products and CFS of IMD).
Cumulative rainfall during week 2, Normal rainfall activities likely over North Eastern States and parts of East India and over the west coast with mainly dry weather likely over rest parts of the country (Refer Annexure III for rainfall anomalies in week 2 and Annexure V for actual and anomalies of rainfall probably from IMD MME CFS-GFS Model). During week 1, heatwave conditions in isolated pockets are most likely over Rajasthan by the 2nd half of week 1. During week 2, Average Max temp anomalies of 2 and 4°C above normal are plotted in Annexure III IMD ERF Forecast max temp anomalies.
Cyclogenesis
Average maximum temperature deviations of 2 and 4°C above normal are plotted in Annex III IMD ERF Forecast maximum temperature deviations. In addition, most of the numerical models analysis and forecast, including ECMWF, IMD GFS, NCEP GFS, NEPS and NCUM, indicate cyclogenesis over central parts of southern BoB dated around 15 May, with intensification into cyclonic storm around 16th and initial north- north-west movement till 17th and north-northeastward repeat during 18th-19th to north-west BoB. MME (CFSv2) also indicates a high probability (>80%) of cyclogenesis over central parts of southern BoB during week 1.
The total live storage in 123 important reservoirs in different parts of the country, monitored by CWC at the end of the week, was 64,600 billion cubic meters (BCM) (38 percent of the storage. The storage was more than last year's position with 26,092 BCM and more than the average of the last ten years storage position by The current year's storage is almost 168 percent of the last year's storage and 165 percent of the average of the last ten years.
The total live storage in 123 important reservoirs in different parts of the country monitored by CWC for the week ended 14 May 2020 is 64,600 billion cubic meters (BCM).

ALL INDIA STATUS
The Central Water Commission monitors the live storage status of 123 reservoirs in the country on a weekly basis and issues weekly bulletin every Thursday. Out of these reservoirs, 43 reservoirs have hydropower benefits with installed capacity of more than 60 MW. The total live storage capacity of these 123 reservoirs is 171,090 BCM, which is about 66.36% of the live storage capacity of 257,812 BCM estimated to have been created in the country.
According to the reservoir storage bulletin, the available live storage in these reservoirs is 64.6 BCM, which is 38% of the total live storage capacity of these reservoirs. However, last year the available live storage in these reservoirs for the corresponding period was 38,508 BCM and the average of the last 10 years was 39,217 BCM. Thus, the available live storage in 123 reservoirs according to Bulletin amounts to 168% of the live storage of the corresponding period of last year and 165% of the storage of the average of the last ten years.
According to table-01, the total storage position is better than the corresponding period last year in the country as a whole and is also better than the average storage space for the last ten years in the corresponding period.
