Chennai, March 25
With summer setting in, the Regional Meteorological Centre (RMC) in Chennai has forecast a gradual rise in day temperatures across many parts of Tamil Nadu, starting Tuesday.
Dry weather is expected to dominate the state, except for districts along the Western Ghats, which may receive light to moderate rainfall until Wednesday.
According to the Regional Meteorological Centre, a north-south trough and wind discontinuity may bring isolated rain to these regions.
However, dry weather is expected to return fully by March 27. The RMC has warned that day temperatures could increase by 2 to 3 degrees Celsius in some areas over the next four days.
Interior districts, in particular, are likely to experience hotter conditions as the influence of minor weather systems fades and dry conditions intensify.
Light to moderate easterly and northeasterly winds in the lower troposphere are resulting in the temperature rise.
Northern coastal districts, including Chennai, Kancheepuram, Chengalpattu, and Tiruvallur, are expected to record a 2 to 3-degree increase in maximum temperatures.
Meteorologists attribute this early summer heat to the La Nina effect, which delayed the withdrawal of the northeast monsoon and resulted in a weaker winter.
The absence of cloud formation and a drop in sea moisture levels have intensified the warming trend across coastal and interior regions.
