Extratropical cyclone, remnant low, tropical disturbance, or monsoon depressionCyclone Wylva originated from a tropical low over the Cape York Peninsula spawned by the westerlies from the monsoon trough.[1] Since the disturbance crossed into the Gulf of Carpentaria on February 14, both the Bureau of Meteorology (BoM) and the Joint Typhoon Warning Center began monitoring it as a tropical low in their respective Tropical Weather Outlooks.[2] Steered southwestward by a firm mid-level ridge to the south, the tropical low developed due to a favourable ridge to the southwest and a well-stacked structure,[1] causing it to develop convection in the monsoon trough and a low-level circulation center.[2] A QuikScat pass just prior to 13:00 UTC on February 15 revealed that the disturbance had a well-defined circulation, with light winds spotted near the center and peak winds of 25–30 mph (35–45 km/h) around the periphery.[2] As a result of being under weak to moderate vertical shear,[2] the low developed into a tropical cyclone by 00:00 UTC the next day, being named Wylva by the BoM.[3] Around thirty minutes later, the Joint Typhoon Warning Center issued a Tropical Cyclone Formation Alert due to a QuikScat pass revealing that Wylva was developing persistent and organizing convection.[2]
Peaking with sustained winds of 45 mph (75 km/h) on 06:00 UTC that day,[4] further development did not occur as Wylva made landfall alongside the Northern Territory-Queensland border around three hours later.[2][4] Although the cyclone's mid-level centre dissipated soon after,[1] the brown ocean effect enabled Wylva to retain some tropical characteristics.[5] Tracking westwards throughout the next few days, the cyclone was able to retain its cloud structure.[1] As a result, despite weakening into a tropical low, Wylva attained a minimum pressure of 988 hPa (29.2 inHg) at 12:00 UTC on February 18.[2] Wylva finally dissipated several days later on February 22.[4][1]
