"A cyclonic circulation lies over the east equatorial Indian Ocean and adjoining Southeast Bay of Bengal and extends up to 3.1 km above mean sea level. Under its influence, a low pressure area is likely to form in the same region on January 27. It is likely to move westnorthwestwards slowly during subsequent three days," said a senior RMC official.

He added, "So, the coastal and delta districts are likely to witness light to moderate rain from January 30. If the low-pressure area intensifies into depression there are chances for heavy rain in the State next week."

For the next two days, the State is likely to expect dry weather due to light to moderate easterlies/ northeasterlies prevail over the region in the lower tropospheric levels. In Chennai, some areas will receive mild showers, and the maximum and minimum temperature will record around 31 degree Celsius and 24 degree Celsius respectively.

Tamil Nadu weatherman Pradeep John said, "In Tamil Nadu, rains will reduce over the next few days. However, The Nilgiris (Gudalur-Devala-pandalur) and Valparai belt will continue to get thunderstorms, and rain."
