Monsoon Watch 6...22nd May 2015:

What we see here are the cloud formation in Mid Arabian Seas...This formation is explained in the last few Monsoon Watch Series articles.


(Refresh from MW-5: "Now, this difference with the Central Arabian Sea plays a key role in cloud formations off the Western Coastline of India in the Central Arabian Seas. The SST along the Somali coast should rapidly fall to around 18/20c in the next 10 days.")

Now, as we see the cloud mass forming, and precipitating rains, we see the west winds picking up. Off the Maldives coast, the winds are gaining strength. 

The main Gan Island in the Maldives has recorded 40 mms rains yesterday, Hanimadu saw 39 mms today.
Monsoon is expected to hit the Maldives in the next 24-36 hrs (by 24th May)....Rest of Monsoon  progress could also be as estimated, by vagaries.. 26th in Sri Lanka, 3rd June in Kerala...
Monsoon progress map ( Right side of Blog) is updated regularly.

The winds remain W/SW South of Sri Lanka and are SW at around 30 knts in the Andaman region.

Remember, we mentioned that the Somali Current forces the Seas on the Somali Coast waters to cool down , and the SW winds rushing into the warmer Arabian Seas form thick clouds in the mid seas...This is precisely what we need.

Also on stream as per last MW 5, we see the core pressure of the seasonal Low dropping to 998 mb today...a significant step which was anticipated in the last MW 5.

Nawabshah and Sibbi in Pakistan recorded 49.0c on Friday. Highest in India was 47.6c at Chandrapur (Vidharbh).

MW-5...2015.....20th May 2015

South West Monsoon has advanced further into North Andaman...

1. Cross Equatorial Flow has picked up considerably in the Bay, and is touching 35 knts. In fact it is showing an independent trend, disassociating itself from the Arabia Sea branch. Winds around 35-40 knts (30 last year) are seen gushing Northwards off the Somali Coast.




But the Arabian Sea branch is dis organised and shows no definite formations from the Somali coast to the West Indian coastline. 
The Eastern branch of the Arabian Sea winds will gain speed, and SW winds will touch 30-35 knts near Maldives and Sri Lanka by the 23rd of May....Heralding the South West Monsoon in the region of Maldives by the 24th. Sri Lanka at this rate should get SWM by 26th May....and Kerala by 3rd June.

2.SST reproduced here to show the Sea temperature falling  along the Somali coast. It is presently around 23c (23)c. { Brackets indicate last year's readings}.




Now, this difference with the Central Arabian Sea plays a key role in cloud formations off the Western Coastline of India in the Central Arabian Seas. The SST along the Somali coast should rapidly fall to around 18/20c in the next 10 days.

But the present fall is not sufficient to help form Monsoon clouds around the Central Arabian Sea. 
A slight rise is seen in the Bay water's SST to 31c.

3.Seasonal Low...Currently dropping to core pressure 0f 1000 mb....But the strengthening flow from the Somali region will bring very strong gusty winds at 35-40 kmph along the Sindh Coast...windy in Karachi from 22nd/23rd. 
This will enhance the drop in the Seasonal Low, which can go down to fall to 996 mb in 3/4 days by 24th May !

Current Weather:


As mentioned yesterday, heat Wave prevailed in Vidharbha, with the highest temperature in India on Wednesday 20th May, being 47.4c at Chandrapur (Vidarbha). Wardha was 47.2c and nagpur 47.0c
Now, 21st and 22nd , Heat Wave is likely to spread to Telangana, and will prevail in Vidharbha and West MP.
Hottest in Pakistan on Wednesday 20th: Dadu, Turbat, Sibbi 47°C.

Mumbai estimate till Sunday 24th: Partly cloudy,Hot and sultry. Days in Mumbai will be around 35c, with humid conditions making the real feel temperatures around 41c in the afternoon ! 
A light drizzle in the weekend may add to sultry conditions..Nights will be very warm at 29c, maybe touching the rare 30c mark this weekend.
Hot and humid for Outer Townships also, no major change.

Goa will be sultry and partly cloudy. Light drizzles may occur during the weekend, bringing more humid conditions.
