All the heavy rainfall pockets of the country are rain deficient at present. Northeast India and the West Coast receive very heavy rainfall during the Monsoon season with few pockets even exceeding 7000 mm in the season.
Though rainfall deficiency figures in these pockets reflect in the overall Monsoon performance, but these rains do not really prove productive. Truly saying, even the normal rains either cause flooding or flow down to the slopes of the mountains or the Arabian Sea.
Monsoon in West Coast
The entire West Coast acts as a barrier to the Monsoon current and receives very heavy rainfall. In this region, the normal averages are extremely high and such heavy rains do not prove useful in any which means. They simply flow down into the Arabian Sea. The table shows the actual and normal rainfall figures for the West Coast till August 18.
Monsoon in Northeast India
If Northeast India achieves the normal target of Monsoon rains then it adds on to the water levels of the mighty Brahmaputra, flooding several places in Assam. The table shows the actual and normal rainfall figures for Northeast India till August 18.
*NMMT – Nagaland, Manipur, Mizoram and Tripura
Northeast India is not very agro-intensive and excess at times prove detrimental. Little less than normal rains prove more beneficial and suffice for maintaining even the eco balance. The terrain is such that excess water flows down to Bangladesh, flooding several parts of the country. Similarly in the West Coast, crops cannot survive excess rains. Yes the normal rains are required for the eco balance but deficiencies to the tune of 10-20% can be absorbed easily by these areas.
