"The downward revision in India's growth forecast factors in the adverse impact of rainfall deficiency and worsening of the euro zone growth outlook," CRISIL said in its report 'India: Macroeconomic Outlook Revision 2012-13'.
As per the Indian Meteorological Department data, the rainfall was expected to be deficient by 15 per cent for June-September 2012.

It also expects the fiscal deficit to surge to 6.2 per cent of GDP in 2012-13 from our earlier estimate of 5.8
