The Meteorological sub-division-wise rainfall for the week is given in Annexure I.

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:

Cumulative seasonal rainfall is given in Annexure II.

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
