Seasonal Rainfall Scenario (01 March to 03 April, 2019)
For the country as a whole, cumulative rainfall during this year’s pre-monsoon
season upto 03rd April is below LPA by 37%. Details of the rainfall distribution over the four
broad geographical regions of India are given below:

Chief synoptic conditions as on 04 April, 2019
o A feeble Western Disturbance as a cyclonic circulation lies over east Afghanistan &
neighbourhood at 3.1 km above mean sea level.
o A cyclonic circulation lies over West Rajasthan & adjoining central Pakistan at lower
levels.
o A trough runs from the above cyclonic circulation to north Madhya Pradesh across
East Rajasthan at lower levels.
o A trough runs from west Vidarbha to Coastal Karnataka across Marathwada &
Madhya Maharashtra at 1.5 km above mean sea level.
o Another cyclonic circulation lies over east Bihar & neighbourhood at lower levels.
o A cyclonic circulation lies over northeast Assam & neighbourhood at 1.5 km above
mean sea level.

Large scale features as on 04 April, 2019
o Currently, weak El Niño conditions have developed over equatorial Pacific Ocean
and the latest Monsoon Mission Climate Forecasting System (MMCFS) forecast
indicates that these conditions are likely to persist in early part of the summer
season and likely to weaken thereafter.
o At present, neutral Indian Ocean Dipole (IOD) conditions are observed over Indian
Ocean and the latest MMCFS forecast indicates neutral IOD conditions are likely to
continue for coming forecasted seasons.
o The Madden–Julian Oscillation (MJO) at present lies over Phase -8 with very weak
amplitude. It is very likely to move towards Phase 1 with weak amplitude during next
one week.
Forecast for next two week
Weather systems & associated Precipitation during Week 1(04 to10 April, 2019) and
Week 2 (11 to17 April, 2019)
Rainfall for week 1: (04 to10 April, 2019)
o Pre- monsoon convective activity is likely to cause scattered to fairly widespread /
widespread rainfall with isolated thunder squalls over west Bengal & Sikkim, adjoining
parts of Bihar, Jharkhand and Odisha and over northeastern states ( Arunachal
Pradesh, Assam & Meghalaya and Nagaland, Manipur, Mizoram & Tripura) on most of
the days during the week 1 and on a few day during week-2. Though the western
Disturbances affecting the western Himalayan region (WHR) are likely to remain feeble,
these, along with other cyclonic circulations are likely to cause isolated to scattered rain
/ thundershowers over WHR and isolated rain / thundershowers and occasional Dust
storms over Punjab, Haryana, Chandigarh & Delhi, Uttar Pradesh and north Rajasthan.
The seasonal north-south trough / wind discontinuity and moisture incursion from the
Bay of Bengal is likely to cause isolated rain / thundershowers over central India
(Madhya Pradesh, Chhattisgarh and Vidarbha) and also over the southern states
(Kerala, Karnataka, Andhra Pradesh and Telangana) on most of the days during this
period.
o Cumulatively, normal to above normal rainfall likely over west Bengal & Sikkim,
Mizoram, Tripura and over the eastern parts of Bihar and Jharkhand, below normal
over Jammu & Kashmir, Himachal Pradesh, Uttarakhand, Tamil Nadu, Puducherry and
Kerala and near normal elsewhere during week -1 (Annexures III & IV).
4
Rainfall for week 2: (11 to17 April, 2019)
o Above normal rainfall likely over west Bengal & Sikkim, Assam, Meghalaya,
Manipur, Mizoram, Tripura and north Kerala, below normal over south Kerala,
south Tamil Nadu and east Arunachal Pradesh and near normal over the rest of
the country (Annexure IV).
Maximum Temperature for week 1 & 2: (04 to 17 April, 2019)
o Above normal (by 3-4ºC) day maximum temperatures are likely over most parts of
Rajasthan, adjoining north Gujarat, Punjab, Haryana, Jammu & Kashmir, Himachal
Pradesh, Uttarakhand, Uttar Pradesh, northern districts of Madhya Pradesh, Odisha
and some parts of Chhattisgarh, Konkan & Goa, Tamil Nadu & Puducherry, north
coastal Andhra Pradesh, Arunachal Pradesh and east Assam and normal to slightly
below normal (by 1-2ºC) over the rest of India during week -1.
o Heat Wave conditions in some parts very likely over West Rajasthan and in
isolated pockets over Madhya Pradesh, south Haryana and East Rajasthan on
tomorrow.
o Warmer than normal day maximum temperatures (by 3-4ºC) are likely over most parts
of Odisha, south Chhattisgarh, Jammu & Kashmir and Himachal Pradesh and above
normal by 2-3ºC over Rajasthan, Punjab, Haryana, Chandigarh & Delhi, Uttar Pradesh,
northwest Madhya Pradesh, east Madhya Pradesh, Arunachal Pradesh, east Assam,
Gujarat, Konkan & Goa and adjoining Ghat areas of Maharashtra, coastal & south
interior Karnataka, Tamil Nadu & Puducherry and north coastal Andhra Pradesh, during
week- 2. Near normal to slightly below normal (by 1-2ºC) maximum temperatures are
likely over the rest of India during this period. (Annexure V).
o There is likelihood of development of heat wave conditions over Odisha and
adjoining areas of coastal Andhra Pradesh on a few days during week-2. Parts of
north and central India may also experience heat wave occasionally during this
period.
Cyclogenesis:
o No cyclogenesis is likely over the Indian Seas during next 2 weeks.
Next weekly update will be issued on next Thursday i.e. 11 April, 2019
