Chennai, Aug 29 (IANS) The Regional Meteorological Centre (RMC) in Chennai has forecast moderate rain accompanied by thunderstorms at one or two places in the Western Ghats districts of Tamil Nadu over the next four days.
Weather officials said a weak low-pressure trough persists in the lower atmospheric levels over the coastal regions of the State.
Under its influence, light rain is likely at a few places on Saturday, particularly across Chennai, Chengalpattu, Villupuram, Cuddalore, Kallakurichi, Tiruchi, Ariyalur, Perambalur, Sivaganga and Ramanathapuram districts.
The Delta districts, along with neighbouring Puducherry and Karaikal, are also expected to receive light showers during the day.
While widespread rainfall is not anticipated, isolated spells could bring temporary relief from the prevailing heat in several parts of the State.
The RMC said one or two places in districts adjoining the Western Ghats could experience moderate rainfall until August 31.
Thunderstorms may be accompanied by gusty surface winds reaching speeds of up to 50 kmph. Residents have been advised to remain cautious during spells of thunder and lightning, particularly in open areas and near trees or weak structures.
Despite the possibility of rainfall, daytime temperatures are expected to remain high. The maximum temperature across Tamil Nadu may rise by up to three degrees Celsius above normal during the next four days, the forecast said.
Hot and uncomfortable conditions may, therefore, persist in areas that do not receive rain.
Meanwhile, a separate warning has been issued for fishermen operating off the southern Tamil Nadu coast.
Squally weather, with wind speeds reaching up to 65 kmph, is likely over the sea until August 31.
Fishermen have been advised not to venture into the southern Tamil Nadu coastal waters, the Gulf of Mannar and the adjoining Comorin Sea during the warning period.
Those already at sea have been urged to exercise caution and follow official weather bulletins. Authorities have also advised fishing communities to secure boats and equipment in view of the strong winds.
The public has been asked to monitor updated forecasts, as local weather conditions could change depending on the movement and strength of the prevailing atmospheric system.
Small fishing vessels are particularly vulnerable in rough seas, and crews have been urged to suspend operations until conditions improve and the weather department officially withdraws its warning after a fresh assessment.
