Chennai Weather : While Cyclone Biparjoy wreaked havoc with torrential rains along India’s western coast, the eastern part of the country experienced contrasting weather conditions. Despite the southwest monsoon being in effect in Tamil Nadu, the northeast movement of the cyclone resulted in a change in wind patterns, leading to uncomfortably high temperatures in the state. However, Chennai, the capital city, received unexpected relief from the scorching heat in the form of surprise downpours. These sudden showers brought relief to the sweltering city, significantly reducing the soaring mercury levels.
Chennai Weather : The Impact of Cyclone Biparjoy
Cyclone Biparjoy, originating in the South West Bay of Bengal, led to the formation of an upper air cyclonic circulation. This circulation interacted with the westerlies, causing a shift in wind patterns across the region. While the western coast experienced heavy rains due to the cyclone, Chennai faced the consequences of the altered wind flow, resulting in unusually high temperatures.
Relief in the Form of Rain
To the delight of Chennaites, the unexpected rainfall began on Sunday, June 18. Initially, the city experienced light to moderate showers. However, the intensity of the rainfall increased overnight, with heavy downpours continuing until Monday morning, June 19. According to the India Meteorological Department (IMD), Chennai’s Meenambakkam observatory recorded 137.6 mm of rainfall between 8:30 am on Sunday and 5:30 am on Monday, while Nungambakkam witnessed 67.4 mm of precipitation during the same period.
Impact on Chennai
The intense rains caused flooding in several low-lying areas of Chennai. Areas such as Velachery, Guindy, Vepery, GST Road, and KK Nagar were particularly affected, with reports of waterlogging. The underpass of Kathipara junction, which connects major roads in the city, including the Grand Southern Trunk Road and Mount-Poonamallee Road, was submerged under 3 feet of rainwater. The heavy rains not only led to traffic congestion but also resulted in the diversion of 10 flights scheduled to land in Chennai to Bengaluru’s airport. Additionally, 17 international flights faced delays due to the inclement weather.
Despite the inconveniences caused by the rainfall, there was a positive outcome. The continuous downpours replenished the Chembarambakkam reservoir, which is a vital source of water supply for the city. The reservoir received nearly 921 cusecs of rainwater runoff until 6 am on Monday.
Weather Forecast and Precautionary Measures
The weather forecasts indicate the possibility of more heavy rains in Chennai and its neighboring districts, including Kancheepuram, Chengalpattu, Tiruvannamalai, Kallakurichi, Villupuram, Cuddalore, Mayiladuthurai, Nagapattinam, Tiruvarur, Thanjavur, Tiruchirappalli, Ariyalur, and Perambalur. These areas can expect rainfall ranging from 64.5 mm to 115.5 mm on Monday. Furthermore, Tamil Nadu is likely to experience scattered to fairly widespread rainfall accompanied by thunderstorms and lightning over the next five days, until Friday, June 23.
Taking these forecasts into account, a yellow watch advisory has been issued for the state, indicating the need for updated weather information. As a precautionary measure, schools in Chennai, Chengalpattu, Kancheepuram, Vellore, Ranipet, and Thiruvallur districts have been closed for the day.
The unexpected relief provided by the surprise downpours in Chennai brought respite to the city, reducing the sweltering heat that had prevailed during the hot June days. Despite the challenges posed by the heavy rains, such as flooding and flight disruptions, the replenishment of the Chembarambakkam reservoir ensures a positive impact on the city’s water supply. While Tamil Nadu continues to experience fluctuating weather conditions, the authorities and residents remain vigilant, keeping an eye on the weather forecasts and taking necessary precautions to ensure the safety and well-being of the people.
