After which it could change to a southwesterly direction over the State and provide respite from the soaring heat. Until then, interior areas and coastal places, including Puducherry and Karaikal, would have to endure the heat. Some districts such as Tiruvallur, Kancheepuram, Chennai and Vellore may experience light rain during the evenings due to convective activity, he said.
