The month of March marks the beginning of Pre-Monsoon season in the Indian mainland. In the Southern Peninsula, Kerala experiences more activities being the South-most and sharing its borders with major water bodies. The pre-Monsoon season has been doing quite poor for South India till now except for Kerala and Coastal Andhra Pradesh. For Kerala, the performance has been satisfactory, if not good at -27% i.e. not largely deficient.
The state of Kerala sees a varied weather pattern in the month of March, with 2017 at 189% and 2018 at 56%.
As we see form the table, there is no consistency in rainfall pattern for the state in the past few years. Troughs in South Peninsula during the Pre-Monsoon season bring in moisture from Indian Ocean. Kerala, being a coastal station is largely dominated by moisture from the surrounding seas. Thus, even a slight change in weather condition readily induces thunderstorms over here.
In the past few days, on and off rain activities have been occurring over Kerala. Forecasting for the rest of the month, Skymet doesn’t see any significant rain activity in the state. Very light isolated rainfall can however occur on a few occasions along the coastline. These rains, might not suffice to take away the deficiency of the state which can plunge close to 30% by the month end.
