Dated:24September 2020

Current Weather Status and Outlook for next two weeks (24 Sept-7 October2020) Significant Features of current week ended on 23 September 2020

Re-invigoration of the monsoon activity by a Low Pressure Area over northeast Bay of Bengal

on 20th, which moved inland on 21st, lay over north Chhattisgarh on 22nd , central Madhya

Pradesh on 23rd and re-curved towards east Uttar Pradesh on 24th.

A northeast-southwest oriented trough in the lower & middle levels extended from north India to

Maharashtra coast across the above system

Enhanced rainfall activity over peninsular India especially west coast & east central & northeast

India

Caused urban flooding in Mumbai and Riverine Flooding in Karnataka

Rainfall over India as a whole was excess during the week(Fig. 1) with % departure from normal

as +40% with Central India, Peninsular India and eastern and northeastern parts of India

received excess rainfall of % dep as +72%, +62% and +40%. But northwest India had received

subdued rainfall with % Dep as -63%.

Regions which experienced very heavy to extremely heavy rainfall during 18-23 Sept were:18th – Rayalaseema, 19th – Coastal & south interior Karnataka (Brahmavar – 39cm), Kerala (Vadakara

– 21cm), 20th – Kerala, coastal & south interior Karnataka, Goa, 21st – Meghalaya (Mawsinram—24cm), Sikkim, Konkan , Goa, Chhattisgarh, 22nd – Assam, Meghalaya, Bihar, Jharkhand, east Uttar pradesh, Konkan (Mumbai SCZ- 29cm), Madhya Maharashtra, 23rd – Bihar, east UP, West MP, south Gujarat, north Konkan Temperature Scenario:The highest maximum temperature of 41.8o C had been recordedat

Phalodi (West Rajasthan) on 23rd September 2020 over the plains of the country during the week. Weekly Rainfall Scenario (for week ended on23 Sept 2020): During the week, rainfall was

excesswith % departure from aboveLong Period Average (LPA) by +40% over the country as a whole.

Chief synoptic conditions as on 24Sept 2020

A Low pressure area lies over central parts of east Uttar Pradesh.

Monsoon trough is north of its normal position with eastern end at the foot hills of

Himalayas

A Trough lies in Westerlies roughly along Long. 65°E to the north of Lat. 28°N in middle

levels.

A trough runs from east UP to north Madhya Maharashtra across Madhya Pradesh at

lower levels .

On Withdrawal of southwest Monsoon 2020 from northwest India

Likely commencement of withdrawal from western parts of northwest India around 28 th Sept.

2020 – delay of more than 10 days from the normal schedule(Map of new normal Withdrawal

dates of southwest monsoon from India given in Fig 2)

However, subsequent withdrawal could follow a near normal pattern.

Withdrawal has been delayed mainly due to active monsoon trough in association with the

formation of 2 low pressure systems

Large scale features as on 24 Sept 2020

The Madden Julian Oscillation (MJO) index is currently in Phase 4 with amplitude slightly greater

than 1. It will remain in Phase 4 with amplitude less than 1 during first half of week 1. It is likely

to move into Phase 5 with amplitude less than 1 from the latter part of week 1 and enter into

Phase 6 during week 2.

3

Currently, sea surface temperatures(SSTs) and atmospheric conditions over equatorial

Pacific Ocean indicate cool ENSO neutral conditions. MMCFS and other global models

indicate SSTs over the region to cool further. However, ENSO neutral conditions to continue

during remaining part of monsoon season.

Neutral IOD conditions are prevailing over equatorial Indian Ocean. MMCFS forecast

indicates development of negative IOD conditions during coming months.

Forecast for next two week

Week 1: (24-30 Sept)

Likely commencement of withdrawal of southwest monsoon from parts of Northwest India

around 28th Sept.

Above normal day temperatures over northwest India and Indo-Gangetic plains

A brief wet spell of light rainfall over Jammu & Kashmir on 25th & 26th Sept. , breaking the

prolonged dry spell.

• Above normal rainfall over northeastern states, Bihar, Odisha, Chhattisgarh, Maharashtra,

Andhra Pradesh and Telangana

• Below normal rainfall over Himachal Pradesh, Uttarakhand, Karnataka & Kerala.. (Refer

Annexure III and IV for more information).

Week 2(1-7 Oct 2020)

• Above normal rainfall over eastern parts of central India, east & northeast India.

• Below normal rainfall over west coast & adjoining south Peninsula.

• Further withdrawal of southwest monsoon likely from remaining parts of northwest India and

parts of central India.(Refer Annexure III and IV for more information).

Maximum Temperature for week 1 & 2: (24 September-7 October , 2020):

During week 1and week 2 Mostly above normal Tmax over central and plains of northern

India during week 1 and week 2. (Annexure V).

Cyclogenesis:The phase of MJO will support convective activity over the north Indian Ocean

during week 1 alone. Most of the numerical models including IMD GFS, GEFS & ECMWF are not indicating any cyclogenesis over the region during week 1 and NCEP GFS during weeks 1& 2. ECMWF however is indicating cyclogenesis over the land during the later part of week 1.NEPS & NCUM indicate probable formation of a Depression over westcentral & adjoining northwest Bay of Bengal (BoB) off north Andhra Pradesh – south Odisha coasts during the second half of week 1. The Genesis Potential Parameter (GPP) based on IMD GFS is also indicating potential zone for cyclogenesis during middle of week-1 over the BoB. The GPP based on CGEPS (MME) is also indicating cyclogenesis with 40 – 50 % probability during second half of week-1. However, all these models indicate chance of formation of a low pressure area over north and adjoining central Bay of Bengal during the second half of week-1 and no genesis during week -2. It is very likely that the remnant of Tropical Storm ‘NOUL’ which is currently over west pacific could move across Vietnam, Laos & Myanmar and emerge into northeast BoB around the middle of week -1. Out of the 7 model products consulted, only 3 of them indicate potential for formation of a Depression over the Sea area. Considering the above, it may be concluded that there is a ‘Low’ probability for cyclogenesis over North Bay of Bengal during second half of week 1.
