Dated: 22 July, 2021

Subject: Current Weather Status and Extended range Forecast for next two weeks

(22 July-4 August 2021)

1. Significant Features for the Country Prolonged isolated extremely heavy rainfall spells (24 hours rainfall > 204.4 mm) occurred

over Konkan and Goa including Mumbai and its sub-urban areas, and Ghat areas of

Maharashtra when it was observed in almost all dates of the week of 15-21 July. It causes

severe flooding and inundation over some districts of Konkan areas including over Mumbai.

Isolated extremely heavy rainfall also occurred over Western Himalayan Region and

adjoining plains (Himachal Pradesh and Uttarakhand and Punjab and Haryana), but it was

during 2nd half of the week i.e. 18-21 July.

Weekly cumulative % rainfall departure for the country as a whole from its Long Period

Average (LPA) was -3% during the week, while it’s Seasonal cumulative % Rainfall departure

from LPA since 1 June till 21 July, 2021 was -5 %. Details of the rainfall distribution over the

four broad geographical regions of India are given Table 1 with met sub-divisions-wise rainfall

both for week and season given in Annex 1.

Forecast for next 2 weeks: Week 1 (22 to 28 July, 2021) and Week 2 (29 July-4 August 2021) based

on NWP model consensus shows “On-going normal to above normal active monsoon conditions

for the country as a whole is likely to continue during the first week and subdued activity is

likely during the second week”.

Based on current model guidance, a low pressure area is very likely to develop over north Bay

of Bengal and neighbourhood during the end of week 1 and beginning of week 2.

country as a whole 66.0 67.8 -3% 339.1 356.7 -5%

2. Large scale features as on 22 July, 2021

Presently, neutral ENSO conditions are seen over the equatorial Pacific along with substantially 3

warmer subsurface temperatures over the region. Atmospheric patterns also reflect neutral ENSO

conditions. The latest MMCFS and other global model forecast indicate that neutral ENSO conditions

will continue during the upcoming monsoon season.

At present, neutral Indian Ocean Dipole (IOD) conditions are prevailing over the Indian Ocean. The

latest forecast from the MMCFS and other global models together indicate possibility of development

of negative IOD conditions during the monsoon season.

The Index of Madden Julian Oscillation (MJO) currently lies in Phase 5 with amplitude more than 1.

It is likely to move into Phase 6 with gradual reduction in amplitude during next 5 days. Thereafter, it

will propagate further eastwards into Phase 8 across Phases 6 and 7 with amplitude remaining less

than 1. Hence the Phase of MJO will support enhancement of convective activity over the north

Indian Ocean (NIO) only during week 1.

3. Forecast for next two week

Weather systems & associated Precipitation during Week 1 (22 to 28 July, 2021) and Week 2

(29 July-4 August, 2021)

Rainfall for week 1: (22 to 28 July, 2021)

A Low Pressure Area lies over Northwest Bay of Bengal & neighbourhood. The associated

cyclonic circulation extends upto upper tropospheric level tilting southwest with height. It is

very likely to move west-northwestwards along the monsoon trough during next 2-3 days.

The western end of monsoon trough at mean sea level is north of its normal position and its

eastern end is south of its normal position dipping to eastcentral Bay of Bengal across

northwest Bay of Bengal. The western end is very likely to shift gradually to its normal

position and eastern end likely to be south of its normal position during next 3 days.

Thereafter, the monsoon trough likely to shift northwards during subsequent 3-4 days.

An off-shore trough at mean sea level runs from south Gujarat coast to Kerala coast. It is

likely to persist during next 2-3 days.

Under the influence of these meteorological conditions;

Fairly widespread to widespread rainfall with isolated heavy falls very likely over

Himachal Pradesh and Uttarakhand on 22nd and 23rd which is likely to increase to

isolated heavy to very heavy falls on 25th and 28th July, 2021. Fairly widespread to

widespread rainfall with isolated heavy falls very likely over Jammu & Kashmir and

Ladakh on 27th & 28th July, 2021.

Scattered to fairly widespread rainfall over plains of northwest India likely during 1st

half of the week with enhanced rainfall activity thereafter with isolated heavy to very

heavy falls over Uttar Pradesh on 25th & 26th and isolated heavy falls on 27th & 28th

July, 2021.

Fairly widespread to widespread rainfall with isolated heavy to very heavy falls very

likely to continue over west coast till 24th July and reduce thereafter. Isolated

extremely heavy falls also very likely over Konkan & Goa & adjoining Ghat

areas of Madhya Maharashtra and Coastal Karnataka today, the 22nd July, 2021.

Scattered to fairly widespread rainfall with isolated heavy falls likely to continue over

Gujarat state till 23rd and fairly widespread to widespread rainfall with isolated heavy

4 | P a g e

to very heavy falls on 25th & 26th July, 2021.

Fairly Widespread to widespread rainfall with isolated heavy to very heavy falls

likely over east & adjoining central India during 22nd to 24th July and reduce

thereafter. Isolated extremely heavy falls also likely over Telangana, south

Chhattisgarh and Vidharbha today, the 22nd July, 2021.

Increase in rainfall activity over northeast India likely on 26th July with fairly

widespread to widespread rainfall with isolated heavy to very heavy falls over the

region.

Isolated to scatted rainfall activity is likely over remaining parts of the country during the

week (Annexure IV).

Rainfall for week 2: (29 July to 04 August, 2021)

The monsoon trough is very likely to be north of its normal position during most days of the week.

Hence rainfall activity is very likely to be confined to the northern parts of the country during this

week.

Fairly widespread to widespread rainfall with isolated heavy to heavy falls very likely over northeast &

adjoining east India during most days of the week.

Fairly widespread to widespread rainfall with isolated heavy falls also likely over Western Himalayan

Region & adjoining plains of northwest India and Uttar Pradesh during most days of the week.

Overall, normal to above normal rainfall activity is likely over Western Himalayan Region, Punjab,

Haryana, Chandigarh & Delhi, Uttar Pradesh, Bihar, Jharkhand, West Bengal & Sikkim and

northeastern states.

4. Cyclogenesis:

Considering existing environmental features and model guidance, it may be concluded that no

cyclogenesis is likely over the north Indian Ocean during the forecast period. However, a

low pressure area is very likely to develop over north BoB and neighbourhood during the

end of week 1 and beginning of week 2.
