August 2014 start promises to wipeout rainfall deficit

The start of the month of August 2014 has brought copious rains to all parts of Goa.

Aided by the activation of monsoon trough on the west coast and a deep depression BB6 travelling from Odisha westwards and now at the border of Rajasthan and M.P. the week ending August 6, 2014 saw nearly 50% excess rainfall in Goa as this chart from IMD, Goa Center indicates:

With this the seasonal rainfall deficit has come down to 15%. In IMD parlance normal rainfall is defined as +/- 19%! Thus this spell of rainfall has helped Goa reach the Normal monsoon range!

The daily Area weighted rainfall for Goa, also prepared by IMD Goa is helpful in gauging the daily variance:

The top three wettest places in Goa continue to remain:

1. Valpoi - 2722.9 mm (107.2 inches)
2. Sanguem - 2251.9 mm (88.7 inches)
3. Margao - 2159.7 mm (85.0 inches)

From Aug 1 to Aug 6 rainfall recorded at Valpoi and Margao was:

Valpoi - 411.4 mm (16.2 inches)
Margao - 201.7 mm (7.9 inches)

The trough is expected go remain active at least till Aug 8, bringing isolated heavy downpour in most parts of Goa, interspersed with bouts of cool sunshine!
