Since May 4, the city of Bengaluru has been receiving on and off rain and thundershower activities. In fact, many districts of Karnataka particularly the region of South Interior Karnataka is receiving pre-Monsoon activities. These rains are likely to continue for the next 48 hours. After that on and off activities will keep affecting Bengaluru and Karnataka until the onset of Monsoon.
The reason for these rains is a north-south trough which is extending from eastern and central parts of the country to interior Tamil Nadu across interior Karnataka since last many days. This is prevailing as a semi-permanent feature during this time of the year.
The moisture feed is available from Arabian sea as well as Bay of Bengal- the reason why these pre-monsoon activities are continuing.
Till now, Bengaluru has received around 50 mm of rains during the first half of May compared to the monthly average of Bengaluru which is 107.4 mm. So, the city is still running far behind its monthly average.
Similarly, the other cities of Karnataka are behind the monthly average and have not touched the monthly average so far. In fact, the pre-monsoon activities usually increase during the fag end of May when Monsoon is about to set in over Kerala. Before the onset of Monsoon over Kerala, rain activities increases significantly over South Kerala and Karnataka.
We expect the rain deficiency of Karnataka to get covered up during the increased rain activities during the last week of May.
For this, we have to wait and see if the intensity of these pre-monsoon activities will be enough to surpass the monthly average.
