During that day the depression moved towards the east and gradually intensified, as convection started to organise while vertical windshear over the system decreased, before the JTWC initiated advisories and designated the depression as Tropical Cyclone 19P. During February 10, 19P started to move towards the southeast while developing further before the FMS named the depression as Ella early the next day, before it turned and accelerated towards the south and passed about 100 miles to the west of the northern tip Espiritu Santo.
