The capital city witnessed very poor rains in September 2024, possibly the lowest in the last two decades. The city gathered a mere 23.4mm of rainfall against the normal of 212.8mm. The month of October is the second rainiest month with a normal rainfall of 168.3mm. The city has received only 65mm of rainfall, till halfway through the month. Last one week, the rainfall had been very light, remaining in just a single digit in 24 hours and totalling in just 11mm. The activity is likely to pick up.
A well-marked low-pressure area is lying over the southern parts of the central Bay of Bengal. An east-west trough extends from the system, running across North Coastal Tamil Nadu, South Interior Karnataka and North Kerala. The trough is passing south of the capital city Bengaluru. Therefore, extreme weather activity is unlikely over the city and suburbs.
The weather system over the Bay of Bengal will move northwest and position over Southwest Bay, tomorrow. It will further close in, to the Tamil Nadu coast, a day later. During this phase, the system will intensify to a depression first and possibly to a storm later. South Interior Karnataka in general and the city of Bengaluru in particular, will have a spillover effect of the system. The city and suburbs are expected to have scattered rain and thundershowers spread over four days, between the 14th and 17th of October. The spread and intensity will be relatively more on 16th October. Monsoon showers will continue even thereafter but with a lesser force and fury.
