Bengaluru: As Bengaluru experiences high temperatures, the India Meteorological Department (IMD) has issued a rainfall alert for this week.
The Met Department predicts that Bengaluru is likely to receive light to moderate showers accompanied by thunder and lightning on Thursday and Friday.
The Met Centre forecast states that these pre-monsoon showers may last two days and are expected to lower maximum temperatures.
With the maximum and minimum temperatures in the city ranging between 36°C and 20°C over the next two days, the IMD forecast indicates that the maximum temperature will drop to 30°C after rainfall on Thursday.
N Puviarasan, head of the Met Centre in Bengaluru, explained that the pre-monsoon showers are caused by an interaction between an easterly trough at the lower atmospheric level and a westerly trough at the upper atmospheric level.
He said, “Currently, Bengaluru is receiving northerly winds, which are causing an increase in temperature. Easterly winds are cooler than northerly winds this season, as North India is experiencing peak summer.”
He further noted that, as per the present synoptic conditions, a circulation lies over the southwest Bay of Bengal, off the Tamil Nadu coast, extending up to 3.1 km above the sea level, along with a cyclonic circulation over Tamil Nadu and its neighbouring regions at 0.9 km above mean sea level.
Under this influence, isolated light rainfall and thunderstorms are likely across Karnataka from April 1 to 3.
