The Indian Meteorological Department has issued a heavy rainfall warning for the City and other parts of south interior Karnataka for the next 48 hours. The City is likely to experience strong winds and heavy rainfall coupled with thundershowers.
The warning was issued on Sunday afternoon because of two prevailing systems, an upper air cyclonic circulation over Bay of Bengal and the other is east-west sheer (strong winds blowing, changing their direction and wind speed) across North Peninsular India.
Due to this most parts of south interior Karnataka will experience heavy rainfall, thunderstorm, hailstorm and squall.
The warning has been issued for the next 48 hours, said IMD- Bengaluru Director Sunder Mahadev Metri. He added that formation of systems and changes in patterns were a common phenomenon during pre- monsoon showers.
On Sunday till 8.30 pm, the City recorded 13.4 mm rainfall and HAL airport recorded 11.7 mm rainfall.
The City till 8.30 am on Sunday (May 17, 2015) recorded the highest rainfall for the month of May, this year of 66.4 mm.
Earlier this month, the highest recorded were on May 3- 12.1 mm, on May 1- 9.7 mm and on May 13- 2.6 mm. HAL airport on Sunday till 8.30 am had recorded 26.4 mm and BIAL had recorded 22.8 mm rainfall. From March 1, till May 17 (8.30 am), the City has received 356 mm rainfall, departure from normal being 246 mm (normal of 110 mm). While HAL airport has received 241 mm rainfall, departure from normal being 135 mm (normal of 106 mm).
Foaming increases
Following heavy rains on Saturday and Sunday, the foaming at the Varthur and Bellandur lakes has increased even as the Karnataka State Pollution Control Board (KSPCB) maintains that there is no solution for it.
KSPCB Chairman, Dr Vaman Acharya told Deccan Herald that when its rains, the churning increases leading to foaming.
“During rainfall, foaming increases. There is no solution for this as it is a natural phenomena. However, we have asked officials from Bangalore Water Supply and Sewerage Board ( BWSSB) to set up sewage treatment plants at the earliest.”
