Rain likely over southern and interior districts of Tamil Nadu over the weekend: IMD
Parts of the southern and interior districts may receive light to moderate rain in one or two places through the weekend. The meteorological department also expects a low pressure area to form over the southeast Bay of Bengal on Monday, an unusual weather phenomenon for this time of year.
Meteorological department officials said 12 districts including Dindigul, Ramanathapuram, Tirunelveli, Madurai and Cuddalore, as well as Puducherry and Karaikal could receive isolated rainfall due to converging easterly winds.
In the past 24 hours ending at 8:30 a.m. Friday, only the Papanasam weather station in Tirunelveli district recorded 1 cm of rain. Chidambaram recorded light rainfall till 5.30pm on Friday.
Officials said a cyclonic circulation was likely to form over the southern Andaman Sea and surrounding areas around Sunday. This may influence the formation of a low pressure area over the southeast Bay of Bengal and southern Andaman Sea on Monday.
Although it raised expectations of another period of rain, meteorologists noted that its impact on the state remains uncertain at this time.
Officials said small-scale weather systems formed near the equator as it transitioned into summer. At times, weather systems have picked up intensity. But, the brewing of weather disturbances needed to be monitored for any impact.
Chennai may experience partly cloudy skies and mist/haze during morning hours till Monday. The maximum and minimum temperature would likely be around 32 degrees Celsius and 22 degrees Celsius respectively.
The atmospheric moisture content and lower minimum temperature could help with foggy conditions in the city, officials said.
Citing IMD data, a social media post by Chennaiyil weather blogging portal Oru Mazhaikalam said only 13 weather disturbances had been observed in February and March since 1891.
