Input: Question: Which of the islands that the cyclone passed over or near has a higher population? Passage:During April 5, 2017, the Fiji Meteorological Service started to monitor Tropical Disturbance 20F that had developed about to the northwest of the Fijian dependency of Rotuma. The system lied within an area of favourable conditions for further development with low to moderate vertical wind shear and warm sea surface temperatures of about . Over the next couple of days, the system moved south-westwards and gradually developed further, before it was classified as a tropical depression by the FMS during April 7. The United States Joint Typhoon Warning Center (JTWC) subsequently issued a Tropical Cyclone Formation Alert on the disturbance, as atmospheric convection consolidated around the system's elongated low level circulation center. During that day, the system was steered south-westwards towards Vanuatu and New Caledonia, by northeasterly winds located to the northwest of a subtropical ridge of high pressure. The system subsequently passed near or over the islands of Maewo and Ambae, before the JTWC initiated advisories on the depression and designated it as Tropical Cyclone 16P early on April 8. The system subsequently passed near or over Malakula, before the FMS reported that it had developed into a Category 1 tropical cyclone, on the Australian tropical cyclone intensity scale and named it Cook.
