Bengalureans were in for a special and cooling surprise on Saturday when they were greeted by cloudy sky followed by thunder showers.
Director of Indian Meteorogical Department (IMD)BPuttanna told Deccan Herald that though this is an unexpected phenomenon, Bengaluru received rainfall this year and last year (in this season). This is not only because of the increasing heat in the City, but also
because of system formations, he said.
"There is an upper air cyclonic circulation over Kumarin area extending up to 0.9 km above mean sea level. This easterly wave is creating a low pressure area from east to west, because of this Tamil Nadu, Kerala, south and interior Karnataka are experiencing thunder showers.
There is also an upper air cyclonic circulation in north India. Here, the westerly winds are prevailing. This also bringing rainfall to the north Karnataka region and in another couple of days coastal Karnataka will also start receiving rainfall and Bengaluru is likely to receive heavy rainfall for the next two days. Thus, we have forecast thunder showers across the State in isolation for the next five days. There will also be a dip in temperatures," Puttanna (who retired on Saturday) said.
He clarified that this is not the mango showers. "These showers happen during the month of April. As on February 28, winter season has ended and summer will start from March 1. This is also called as the pre-monsoon shower season," he added.
The City recorded a maximum and minimum temperature of 32.4 and 21.4 degree Celsius on Saturday respectively. HAL airport recorded 31.9 and 20.1 degree Celsius respectively.
City and HAL airport received 0.6 mm and 2.8 mm rainfall.

next five days. Meteorological Department Director B. Puttanna told

level and it was embedded in an eastern wave, which effected the eastern parts of the State. “Saturday is the last day of winter and the period from March 1 to
