2. On the same day.

22nd night post

Some good news for Mumbai..at last 😀

The South Westerly winds regain strength along the Konkan coast after the effect of the Cyclone is gone.

Check the estimated strength on 25th👇


Hence, we can expect the Monsoon to now advance into North Konkan and Mumbai by 25th June. 

Rainfall will increase in Mumbai from 23rd night, and from 24th, Mumbai will get frequent showers. 

A definite change in weather from 25th.

The onset date may tally with the most delayed monsoon arrival for Mumbai,  which was 25th June in 1959 and 2019.

But this does not necessarily mean weak rains.

Wednesday, June 21, 2023

21st June..Morning:

SW surface wind flows are weak. Typical weak monsoon currents.


Also Depression, ( remnant of cyclone) crashing onto Himalayan ranges is normally a "break monsoon " phenomena.


But since monsoon yet to set on above Goa/S. Konkan, Vagaries terms it as a weak Current.

Not normally occurring in June.


Vagaries estimates this situation will change by the 24th, when the depression near the Himalayas fizzles out. 

Monsoon currents will gain strength after 24th,  and will advance over into North Konkan,  including Mumbai/Pune by 25th.

Interesting point: 25th June is the record date for the most delayed monsoon arrival for Mumbai by IMD in 1959 & 2019. However,  Vagaries had observed 27th June as Monsoon arrival in Mumbai for 2019.

19th June 

Massive Rainfall in Rajasthan even before Arrival of Monsoon...

24 hrs Rainfall in cms





Monday 19th June morning Satellite image







1: Remnants of Cyclone Biparjoy still maintaining the intensity of a depression
2: SW Monsoon active over Northeastern states
3: SW Monsoon clouds over the Arabian Sea off the west coast, but no significant rain over the coast
4: Monsoon Thunderstorm and rainclouds over Chennai which gave heavy rain overnight (associated with an upper air circulation over southwest Bay of Bengal)


Mumbai: The wait for proper Monsoon rains continues. Monsoon onset with some heavy showers is likely by 25th-27th June. 


Rainfall over coastal Karnataka, Goa and south konkan may increase gradually from 23rd/24th June. 


मराठवाड्यात  ते ३० जूनपर्यंत मान्सूनचे आगमन होण्याची शक्यता आहे. या हंगामात 3 महिन्यांच्या पिकाची पेरणी करणे योग्य ठरू शकते.

Mennambakkam 158 mm

Sunday, June 18, 2023

Weather outlook from Sunday 18th June to Wednesday 21st June:


Remnants of cyclone Biparjoy presently over Rajasthan as a depression, can weaken to a low pressure area over Rajasthan by tomorrow as it tracks slowly east-northeast.

Heavy to very heavy rains likely across central, southern and eastern parts of Rajasthan (Jodhpur/Jaipur) today and tomorrow. 




Rains may spread east into parts of Madhya Pradesh and southern parts of NCR region by the night of Sunday 18th and into Monday 19th June. 
Uttar Pradesh can get moderate rain from remnants of Biparjoy on Tuesday 20th June and Wednesday 21st June.


Monsoon remains active over NE states, heavy rain to continue for next 3-4 days. 

Hot day/heatwave conditions to continue for parts of east India for more 2-3 days. Night temperatures can also be above 29-30C in places across Vidarbha, Andhra Pradesh and parts of Odisha. 

Thunderstorms are expected across interior Tamil Nadu and south interior Karnataka for next 3-4 days. 
Bangalore, Mysore, Chennai can get thunderstorms. 

West coast: Some patchy showers continue for coastal Kerala and some parts of Karnataka and Goa. 

Monsoon revival is expected after 21st June. This will bring much needed heavy rains over west coast in the last week of June and also help in advancing Monsoon into the remaining parts of Maharashtra as well as into central and east India.

Cyclone Biparjoy is making landfall on Kutch coast. 


It has weakend, so winds can be around 100-110 kmph. 

Most of the clouds are to the south of the center. So heavy rainfall may start after the center moves over land, and the clouds to the south of the center come over land.

 Latest on "Biparjoy" as on 12th Evening.

Very Severe Cyclonic storm, Biparjoy" , lost some steam to a small extent, as its winds are now surpassed the peak and slightly less at 145-155 Kmph. Cat.2. Was anticipated yesterday after touching about 20N. 

As dry air entry is increasing, the overall convection cover is reducing. A band of convection still covering the circulation, the JTWC terms the core as a "Quasi Eye".

With the ridges alongside, expected track..heading towards the North Kutch/International border region.



Alert: Very heavy rainfall and squally winds in Kutch, Western Saurashtra from 14th. Rains commence into North Gujarat and South Rajasthan from 16th.

Karachi & Southern Sindh will get heavy showers and rain from 14th to 15th, with squally winds. 

Monsoon advance beyond South Konkan may be halted for a few days, as the Cyclone moves inland and disturbs the gradient along the West Coast.

Mumbai

*Next 3/4 days will get light to medium Pre Monsoon showers. Squall winds around 30 Kmph. 

*A slight reduction in rains after Wednesday 14th. No major increase in rainfall this week.

*A distinct absence of the usual thunderstorms is noticed. This is as "multi Layer" clouds are not seen. But  thunder activity will soon  resume.

*Days will be a shade better at around 33/34c, but humid. Real feel will be high (38c). Nights around 27c will be warmish.

*Wait for proper Monsoon is frustrating !😖

Pune: With warm days around 35c, will be almost dry, with few localised scattered rain patches.

Goa: Monsoon looses steam after Wednesday 14th...with little rains as the pull of the system reduces.
