Chennai, April 20 (NationPress) Just days ahead of the state Assembly elections scheduled for April 23, the Regional Meteorological Centre has predicted ongoing rainfall across various regions of Tamil Nadu over the upcoming four days. This weather pattern is attributed to an atmospheric trough that stretches from Telangana to the Comorin area.
The meteorological office reports that a trough exists at approximately 1.5 km above the average sea level, extending from Telangana through Rayalaseema and into interior Tamil Nadu, reaching the southernmost part of the peninsula. This weather system is anticipated to affect conditions in multiple districts, especially along the Western Ghats and southern coastal areas.
As a result, light rain, along with thunderstorms, lightning, and strong winds, is forecasted for isolated locations in the Western Ghats, southern coastal Tamil Nadu, delta regions, and Karaikal on Monday and Tuesday.
Wind speeds during these weather events may reach between 30 to 40 kmph, according to the department.
In contrast, most other areas of Tamil Nadu and Puducherry are expected to remain predominantly dry during this timeframe.
The weather office also mentioned that on April 22 and 23, similar weather conditions are projected to continue, with light to moderate rainfall expected in one or two locations across the Western Ghats, southern coastal districts, delta regions, and Karaikal, accompanied by thunderstorms and similar wind intensities.
From April 24 to 26, light to moderate rain is anticipated to persist at isolated spots in the Western Ghats, southern Tamil Nadu, delta districts, and Karaikal, indicating a prolonged period of unsettled weather.
Despite the anticipated rainfall, maximum temperatures across Tamil Nadu, Puducherry, and Karaikal are unlikely to see significant changes until April 24, although slight increases may occur in certain areas. Coastal regions are expected to record near-normal maximum temperatures.
For Chennai, the forecast predicts partly cloudy skies on Monday and Tuesday, with maximum temperatures likely ranging between 37 and 38 degrees Celsius, and minimum temperatures around 28 degrees Celsius.
The combination of high humidity and elevated temperatures is likely to cause discomfort for residents. Authorities have urged people, especially those in vulnerable areas, to exercise caution during thunderstorms and windy conditions.
Point of View
The forecasted rainfall across Tamil Nadu is noteworthy. While some districts will experience significant weather changes, many areas will remain dry. This situation calls for residents to stay informed and prepared as weather conditions can quickly shift.
