As the low pressure in Rajasthan moves west, lying over SW Rajasthan and adjoining Sindh (Pakistan), it intensifies a bit. We had anticipated a bit of strengthening yesterday.

Moving west, system will move away from Kutch, and weaken by tomorrow evening over Sindh Pakistan. The Hyderabad region in Sindh will receive heavy rains on Thursday, with some heavy thundershowers in Karachi during Wednesday night. Decrease in rainfall from Friday. Overnight rain amount may be around 30 mms.

Hi Rajesh/Pradeep,

1. With kind of rains Rajisthan/Gujarat have been receiving for past 10 years it is incorrect to label them as dry/desert states but should have been moist evergreen states.

a. Year 2010 has seen Saurashtra/Kutch receiving 800mm of rains in 2 days (400mm + 400mm)

b. cyclones/low pressures/UAC move regularly in these areas without fail

c. Year 2011 has seen most of lows over Bay ending up in these areas with torrential rains as seen today (350mm of rain in 24hours)

d. Sand dunes have dissappeared over most areas of Rajisthan instead lakes have formed.

e. Cultivation of rice, dates, apples, cashewnuts have started

f. Tourism has been affected in Jaismler as tourist expecting Sand dunes instead finding lakes and greenary!!!

With this we need to study change in climate pattern over India. South India - Interior peninsula - TN are turning into deserts with no rain, no low pressures, no cyclones.

Thanks

sset: The thar desert does get such heavy rainfall occasionally.Of course its mainly dry, but with there are instances of some places in Kutch receiving up to 500 mms in a day.
Western Rajasthan is still sand and desert, and receives very little rainfall.
I think S.india is lashed by rains Oct-Dec. That is the actual rainy season, isnt it ?

Thanks Tyrone, always welcome.
