Dated: 03 September 2020

Current Weather Status and Outlook for next two weeks (03-16 September 2020)

Significant Features of current week ended on 02 September 2020

Last week’s well marked Low Pressure Area (LPA) over southwest Jharkhand moved upto

Punjab & adjoining Pakistan across Madhya Pradesh, Rajasthan during 27 Aug to 02 Sep.

Monsoon trough oscillated north- south of its normal position during the week.

A north-south trough ran across extreme south Peninsular India during the week.

Due to above systems, active monsoon condition prevailed consecutively for 4th week

leading to +31% excess rainfall during the week(Fig. 1). Excess rainfall was mainly

over central and adjoining western India.

Excess rainfall was mainly over Odisha, Chhattisgarh, Madhya Pradesh, Rajasthan

and Gujarat accompanied with isolated extremely heavy rainfall which led to Riverine

flooding, inundation of low lying areas and urban flooding especially over Odsiha

Madhya, extreme southern parts of Raj and south Gujarat.

Extremely heavy rainfall warnings along with its impact was issued 3-4 days in

advance.

As expected, during active monsoon conditions, northern parts of India and parts of

Peninsula received deficient rainfall.

Extremely Heavy Rainfall Activities reported during the week: Heavy to very heavy

rainfall with extremely heavy rainfall at isolated places had been occurred over East and

West Madhya Pradesh and Saurashtra & Kutch on two days each; over Chhattisgarh,

East and West Rajasthan, Sub Himalayan West Bengal & Sikkim and Odisha on one

day each during the week. Chief amount of Extremely heavy rainfall recorded (in cm)

Odsiha: 27th

Temperature Scenario: The highest maximum temperature of 38.8 o C had been recorded

at Thiruchirappalli (Tamil Nadu) on 29th August 2020 over the plains of the country during

the week. LEGEND: A few days- 3 days, Many days- 4 to 5 days and Most days- 6 to 7 days during the week.

Weekly Rainfall Scenario (for week ended on 2 Sept 2020): During the week, rainfall was

excess with % departure from above Long Period Average (LPA) by +31% over the country as a

whole. Details are given below:

Fig 2 shows all India Monsoon rainfall in Aug 2020 in terms % departure from

normal compared to earlier years with data since 1901. It shows rainfall was excess

by 27% in Aug 2020 and was highest after Aug 1976 (28.4% above normal) i.e. in 44

–years. It is also fourth highest in last 120 years. The ever highest percentage

departure for the month during the last 120 years had been 33.1% recorded in the

year 1926. In Aug 2020, Five low pressure systems formed during 4-10 , 9-11, 13-18 , 19-26 and

24-31 August 2020 which caused such higher than normal rainfall over central and

western part of India. All these formed over north Bay and moved across central

India upto West MP/Rajasthan. Total number of low pressure days was 27 against

normal of about 15. It caused riverine floods over Odisha, Telangana, Madhya

Pradesh, Gujarat and Rajasthan.

Seasonal Rainfall Scenario for Monsoon Season of 2020 (1 June-2 Sept 2020)

For the country as a whole, Seasonal cumulative rainfall during this year’s southwest

monsoon season upto 2 Sept 2020 was above Long Period Average (LPA) by +9%.

Cumulative seasonal rainfall is given in Annexure II. Chief synoptic conditions as on 3 Sept 2020

3

Western end of monsoon trough lies south of its normal position and its eastern

end lies north of its normal position.

A cyclonic circulation lies over northwest Rajasthan and another over northwest

MP at lower levels.

A cyclonic circulation lies over eastcentral and adjoining southeast Arabian Sea

off Karnataka & north Kerala coasts at lower & middle levels.

Large scale features as on 3 Sept 2020

The Madden Julian Oscillation (MJO) index is entering into Phase 4 with amplitude less than

1. It will remain in Phase 4 with amplitude less than 1 during week 1 & most part of week 2. It

is likely to move into Phase 5 with amplitude less than 1 towards the end of week 2.

Currently, ENSO-neutral conditions to week cool anomalies are prevailing over equatorial

Pacific Ocean and the latest MMCFS forecast indicates these conditions are likely to continue

for the entire forecast period. The sea surface temperature (SST) map for the tropical Pacific

Ocean for the week ending 30 August show cool anomalies in the central and eastern Pacific

have continued to strengthen over recent weeks. Cool SST anomalies in the central and

eastern equatorial Pacific extend across the tropics and to the south of the equator in the

eastern Pacific.

At present, near neutral IOD conditions are observed over Indian Ocean and the latest MMCFS

forecast indicates same IOD conditions are likely to continue during the entire forecast period.

Forecast for next two week

Week 1: (3-9 Sept)

Major likely weather systems

• Western end of monsoon trough to continue to run south of its normal position till 5th

Sept. and shift towards foothills of Himalayas thereafter.

• The eastern end of monsoon trough to remain to the north of its normal position

throughout the week.

• No Low Pressure Area formation likely over Bay of Bengal.

• The cyclonic circulation over eastcentral and adjoining southeast Arabian Sea off

Karnataka & north Kerala coasts at lower & middle levels likely to remain over the same

area till 8th September

Weather warning for next 5 days

Isolated Heavy rainfall accompanied with thunderstorm & lightning very likely over

North Haryana and west Uttar Pradesh on 03rd September; over Himachal Pradesh,

Rajasthan on 03rd & 04th September; over Uttarakhand during 03-07 September, 2020.

Fairly widespread to widespread rainfall with isolated heavy falls and thunderstorm &

lightning very likely over Peninsular India during next 5 days.

4

Unlike previous two weeks, no intense rainfall spell leading to extremely heavy rainfall

likely.

Cumulatively rainfall during week 1 After continuous excess rainfall for the country as a

whole for the four consecutive weeks, it is expected to decrease during next two weeks

becoming normal activity during week 1 and below normal rainfall activity during week 2. (Ref

Annex III for subdivision wise and date wise rainfall generalized forecast and Annex IV

for MME forecast).

Week 2: (10 to 16 September 2020):

Major likely weather systems

• The monsoon trough is likely to remain north of its normal position or close to the

foothills of the Himalayas.

• Development of features for monsoon withdrawal from western parts Rajasthan likely

during the week.

• Formation of low pressure area is unlikely.

• Above normal rainfall activity likely over northeastern states, Maharashtra, Goa,

Karnataka and Kerala.

• Below normal rainfall activity is likely over remaining parts of the country with significant

reduction in rainfall activity over northwest India. (Annexure IV).

Maximum Temperature for week 1 & 2: (3-13 September, 2020):

During week 1 Most parts of India likely to experiences below normal maximum temperature

during the week except northeast India and West coast of India.

During week 2, Most parts of India likely to experiences below normal maximum temperature

during the week except west coast, northeast and adjoining northeast India. (Annexure V).

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

during week 1 and week 2. Most of the numerical models including IMD GFS, GEFS, ECMWF,

NEPS & NCUM are not indicating any cyclogenesis over the region during week 1 as well as

NCEP GFS during weeks 1&2. The Genesis Potential Parameter (GPP) based on IMD GFS is

not indicating any potential zone for cyclogenesis during week-1. The GPP based on CGEPS

(MME) is also not indicating any cyclogenesis during weeks-1 & 2.Considering the above, it

may be concluded that there is no cyclogenesis likely over the north Indian Ocean during

weeks 1 & 2. (for details on cyclogenesis pls see http://www.rsmcnewdelhi.imd.gov.in
