Independent weather blogger Pradeep John, known as Tamil Nadu Weatherman, also predicted that the fog would persist on Friday morning in northern Tamil Nadu, including Chennai. The fog is also due to the varying temperature between land and sea, which causes mositure condensation, as reported by News 9 Live.
As the week progresses, residents of Tamil Nadu, particularly in Chennai and surrounding regions, are bracing for continued foggy mornings and cooler temperatures.
Meanwhile, the cold weather and foggy conditions have brought some respite from the usual heat but have also posed challenges for commuters and daily wage workers who rely on early morning travel. The Regional Meteorological Centre (RMC) is closely monitoring the situation.
