The latest map of cumulative seasonal rainfall for the country as released by IMD, for rainfall between June 1, 2015 to July 11, 2015, clearly indicates that while rest of the country by and large has received normal or excess rainfall, the west coast of India including Konkan & Goa has received deficient rainfall. This is indicated by red colour in the map:
Rainfall below 19% of normal is categorised as Deficient.
Konkan & Goa sub division is estimated to have received -20% of normal rain during this period, putting it in deficient category. Rainfall deficiency in Goa state is now touching -23% alone.
Rest of India has received good rainfall and overall the departure is only -1%, as per the map above.
The reason for the poor performance of monsoon in the west, is mainly due to weak monsoon trough and weak MJO. Also as seen in July so far, the low in BoB and the monsoon axis being northward, resulted in good rains in North India but poor rains in West. The western disturbance WD from Pakistan also had a field day in NW India, giving good rains, as the monsoon axis remained north bound. El Nino Factor has so far not played much role in the above scenario, in context of rest of India.
The monsoon is expected to remain weak in west, for a few more days, till favourable developement for strengthening of monsoon trough happen.
