"The system would be moving in favourable weather conditions as Sea Surface Temperatures (SSTs) would be around 29 degrees Celsius that are conducive for the formation of cyclonic storms,” it said. The agency further informed that despite favourable factors, this storm, the very first one of this season doesn’t seem intense in nature.
"When the monsoon current is strong/aggressive/active, it tends to suppress the cyclonic storm", it added. Reports inform that the low-pressure area is expected to be formed by Thursday, before undergoing gradual strengthening into a powerful cyclone likely headed for Tamil Nadu, past East Sri Lanka, over the next three to four days.
