On 26 March, an area of disturbed weather was located within the
near-equatorial trough near
Papua New Guinea. Initially located within an area of easterly
wind shear, it tracked westward, due to the presence of a
ridge to its south, and on 27 March, a
low-pressure area formed over
Western New Guinea. Thunderstorm activity increased around a mid-level circulation as it crossed into the
Arafura Sea, and its overall organisation continued to increase. On 29 March, a low-level circulation was visible, though significant tropical development was prevented due to wind shear and land interaction with islands in the Indonesian archipelago. The system developed into a tropical low on 30 March. After turning to the southwest, the tropical low crossed the island of
Flores on 31 March; upon doing so, the storm's
convection greatly increased, due to increased
upper-level divergence, which produced heavy rainfall on Flores and
Timor. On 1 April, wind shear decreased as the system crossed into the
Savu Sea, and the storm developed into a tropical cyclone to the northeast of
Sumba. At 1200
UTC on 1 April, the
Joint Typhoon Warning Center (JTWC) issued its first advisory on the system, classifying it as Tropical Cyclone 26S. At 0000 UTC on 2 April, the
Bureau of Meteorology (BOM) warning centre in
Perth classified the system as Tropical Cyclone Inigo. The storm quickly intensified as it tracked southwestward, aided by low wind shear and strong divergence. An
eye featured gradually organised, Upon reaching peak intensity, Inigo maintained an eyewall in diameter. Late on 4 April, an approaching upper-level
trough increased wind shear over the system, which caused a steady weakening trend. On 5 April, the eye became cloud-filled, and later that day the cyclone reached its westernmost point before the approaching trough turned it to the southeast. By 7 April, its winds decreased to below severe tropical cyclone status, or below . The convection continued to decrease, leaving the centre exposed from the convection as it made
landfall early on 8 April, in the
Pilbara region of Western Australia. Upon moving ashore, Inigo had winds of around . Inigo's circulation dissipated within 12 hours after moving ashore. ==Impact==
