Severe Tropical Cyclone Ernie is currently a powerful tropical cyclone located in the southeast Indian Ocean. It is the first storm to become a Category 5 on the Australian scale since Cyclone Marcia in January 2015, and currently the strongest storm worldwide in 2017. Developing from a tropical disturbance south of Indonesia on 6 April, the cyclone intensified into a tropical cyclone shortly afterwards. Late that day, Ernie began a period of explosive intensification, becoming a high-end Category 4-equivalent cyclone just over 24 hours after it formed.
