The Arabian low pressure is expected to fade away as it move westwards/south-westwards due to strong vertical wind shear and dry air while the Bay’s depression has some potential of making landfall as it moves north-eastwards.

Low pressure in the Arabian sea?

But large number of models show a quiet Arabian sea till the beginning of June. A poll conducted by PWP on May 7 shows that 71% people believe that this year Arabian sea would give rise to a tropical depression eariler than the Bay of Bengal.

Dense cloud formation taking place near Andaman sea on May 18

The Indian Meteorological Department believes that the Monsoon would hit Kerala on the normal date of June 1. Almost all models continue to show that the temperatures of the Pacific ocean are expected to rise, giving a clear way for the unfriendly monsoon phenomenon known as El-Nino to return which means that deficient rainfall could occur in many parts of the Indian Sub-continent. Though the IMD has predicted a normal monsoon this year but during the last El-Nino year in 2009, the IMD predicted above-normal monsoon for India though the country was welcomed by the worst drought since the 1970s.

Pakistan usually gets to see its share of monsoon during the first/second week of July.
