This September wettest in Bengaluru since 2005

BENGALURU: The record rainfall for September in Bengaluru, 516.6 mm, dates back to 1986. As of September 27, several parts of the city have already broken that record.

When compared with Indian Meteorological Department (IMD) rainfall data for the past decade, September 2017 has been the wettest since 2005. The city received 352.6 mm during the month in 2013, while this year, Bengaluru has already received 354.28 mm.

The rather heavy (35.5 mm to 64.5 mm) to very heavy rainfall (exceeding 124.5 mm) recorded in the city has pushed the amount of rainfall received in some parts of the city to 640.5 mm. Many other localities in south and east Bengaluru have exceeded the maximum rainfall of 516.6 mm recorded in September.
According to data, rainfall recorded in September is about 2.3 times the normal for September, which is 155 mm.

Forecast

The Indian Meteorological Department has forecast heavy showers for the city, for at least one more day. The forecast for Wednesday indicated that some parts of the city might receive rainfall in excess of 100 mm. Overcast conditions were reported in many parts of Bengaluru and south interior Karnataka.

The rainfall map of Karnataka State Natural Disaster Monitoring Cell (KSNDMC) for Bengaluru indicated that the highest rainfall was recorded at Hemmigepura with 139.5 mm, as of 8.30 am on September 27. Kengeri, Bagalakunte and Basavanapura received 128 mm rainfall.

Heavy rains wreak havoc in Bengaluru

Heavy rains in Bengaluru and surrounding districts on Wednesday crippled normal life, flooding roads and houses and leading to traffic snarls in many localities in the city.

"The city received heavy rainfall on Wednesday, with a few areas receiving a maximum rainfall of 196 mm as recorded at 8.30 a.m," an official from the Karnataka State Natural Disaster Monitoring Centre (KSNDMC) told IANS here.

Bengaluru has received nearly double the normal amount of rainfall for the month of September. It received 295 mm of rain from September 1 to 26 as against the normal of 148 mm, according to the KSNDMC.

The heavy rains which began on Tuesday night led to storm water drains overflowing onto the roads in several localities, leading to water-logging. A number of trees were also uprooted due to the rains in the city, blocking vehicular movement.

A 48-year-old man, Narayanappa, reportedly died at Alur in the city's north suburb when the tiled roof of his old house collapsed in the rains.

Even upscale suburbs like Koramangala and Jayanagar witnessed flash floods as the drains, filled with silt and filth, failed to cope with the huge amounts of water. Rainwater also entered homes in many areas.

Fifty-five-year-old Meenamma, a resident of Krishnarajapuram, a suburb in the eastern part of the city, died on Wednesday after a night of incessant rain, police said.

"Her house was inundated after the rainfall. It was a natural death as she had been suffering from illness for weeks," police constable Chikkarayappa from Krishnarajapuram Police Station told IANS.

A few compound walls in the city also came crashing down due to the night's rain.

"A compound wall in western suburb Chandra Layout collapsed due to the rain, crushing about eight cars that were parked close to it," Bruhat Bengaluru Mahanagara Palike spokesman Suresh said.

Thousands of chickens at a poultry farm in Nelamangala, a town in Bengaluru Rural district, about 30 km from the city, died after the farm was flooded by rain water, an official said.

The Bellandur Lake, the largest of the lakes and tanks in the city, was seen covered in toxic foam after the rainfall. Similar froth has led to the lake catching fire several times in the past.

Binnamangala Lake in Nelamangala town of Bengaluru Rural district, about 35 km to the north west of the city, breached after the excessive rainfall, leading to water flowing on the roads in the town.

Many villages and towns in south interior Karnataka, especially in Mysuru region like Mandya, Bidadi, Srirangapatna and Channapatna, have been badly affected due to the rains.

According to KSNDMC officials, heavy rain is likely to continue in the state for the next three days.

"An east-west shear zone is prevailing over the region, at 5.8 km above the sea level, wherein winds from west to south and east to north converge to cause instability, thereby leading to rains in the state," Sundar M. Metri, the Bengaluru chief of India Meteorological Department, told IANS.- IANS

September rain in Bengaluru inching up to the all-time record of 1986
City is just 20 mm short of the 516.6 mm rainfall recorded that year

The monsoon this year is gearing up to blow away yet another record. Bengaluru's rainfall has been steadily rising and is now on its way to breaching the highest ever rainfall recorded in September since measurements began late in the 19th century.

With more than 59 mm rainfall on Tuesday night and Wednesday afternoon, the city has so far recorded 496.1 mm in September, according to the India Meteorological Department (IMD). This is just 20 mm short of the all-time monthly record of 516.6 mm set in 1986.

However, with IMD predicting more rainfall over the next 48 hours, and Karnataka State Natural Disaster Monitoring Centre (KSNDMC) forecasting heavy rain in the northern and western parts of the city, the record is most likely going to be broken.

Unusual monsoon

This has been quite a turnaround in terms of rainfall in what could be the most tumultuous monsoon the city has witnessed. An urban drought was a real possibility even in August first week. Till then, the city had barely received 80 mm of rainfall, or a more than 65% shortfall.

The scenario started to turn on Independence Day when 129 mm was recorded in 24 hours. Since then, a steady build-up of clouds has seen near-record rainfall in August, which spilled over to a very wet September.

As reported in The Hindu, rainfall varies significantly across the immense landscape of the city. So, during September if Kengeri in Bengaluru south received a staggering 640.5mm of rainfall, Chowdeshwari ward in the north has stayed relatively dry with just 185.5mm of rain.
