Chennai, July 17 (NationPress) The India Meteorological Department (IMD) has issued a yellow alert for Chennai, Tiruvallur, Kancheepuram, and Chengalpet districts, predicting heavy rainfall of 6 to 12 cm on Thursday.
This alert is a much-needed relief for residents who have been enduring hot and dry weather over the last several days.
A yellow alert, according to the IMD, indicates a chance of moderate rainfall. Although it is not severe, it may lead to localized flooding in low-lying regions or disrupt outdoor plans.
The IMD forecasts that the rainfall will be accompanied by thunderstorms and lightning, especially during the evening or nighttime. This could help lower daytime temperatures in the following days due to increased cloud cover.
The maximum temperature is expected to hover around 35-36 degrees Celsius, with a minimum of 26-27 degrees Celsius.
Tiruvallur and Kancheepuram are anticipated to experience continued heavy rainfall from July 18 to 20.
Several districts in northern Tamil Nadu are also expected to receive substantial rainfall during this timeframe, while regions near the Western Ghats are under an orange alert for very heavy rainfall (ranging from 6 cm to 20 cm) on July 19 and 20.
Meteorologists have linked the expected rainfall to convective activity caused by wind convergence associated with an upper air circulation.
Weather analysts have indicated that thunderstorm activity is likely to persist in Chennai and its nearby suburbs in the upcoming days.
“One or two spells of moderate to heavy rain with thunderstorms and lightning are expected over the city and its suburbs on Thursday,” stated the IMD bulletin.
It also noted that the sky will remain partly cloudy. On Wednesday, however, the weather was dry and humid, with Nungambakkam recording a maximum of 36.4 degrees—one degree above normal—and Meenambakkam hitting a scorching 38.1 degrees—2.5 degrees above normal.
Humidity levels ranged between 59 percent and 65 percent. Areas, including Chennai, that have experienced multiple dry days, are likely to face frequent thunderstorms in the coming days.
Despite recent dry spells, Chennai has received approximately 15 cm of rainfall since June 1, which is 26 percent above normal. In contrast, Tamil Nadu as a whole has recorded 7 cm of rainfall, which is 13 percent below the seasonal average.
Point of View
The issuance of a yellow alert by the IMD reflects the organization's commitment to keeping citizens informed about weather conditions. The expected rainfall is a reminder of the dynamic nature of our climate, and preparedness is essential. As we navigate these weather patterns, maintaining awareness is crucial for safety.
