Seroja was the 10th cyclone to hit Indonesia since 2008 and the strongest to date, killing over a hundred people. - AFP JAKARTA (The Straits Times/ANN): Rising sea temperatures due to global warming were responsible for tropical cyclone Seroja, which triggered devastating floods and landslides in Indonesia's East Nusa Tenggara islands on Sunday (April 4), Indonesia's weather agency has said. More than a hundred people lost their lives in the disaster. "Seroja is the first one to bring tremendous impact because it hit the land. It's uncommon," she added. Indonesia's last major tropical cyclone, Cempaka, formed in the sea in November 2017, and largely dissipated when it hit landfall.
