    The first named storm of the 2022-2023 Australian region cyclone season
    formed on December 18, 2022, in the South Indian Ocean. It was dubbed
    Tropical Cyclone Darian by the Australian Bureau of Meteorology.

    By December 19, Tropical Cyclone Darian’s maximum sustained winds had
    increased to 75 mph (121 km/h), placing it in Category 1 on the
    Saffir-Simpson Hurricane Wind Scale. Thanks to favorable conditions—low
    wind shear and warm sea surface temperatures—the storm continued to
    intensify, reaching peak strength on December 20. At that time, maximum
    sustained winds registered at 145 mph (233 km/h), making it a Category
    5 storm. Late the next day it began to weaken as it meandered over the
    Indian Ocean, becoming a tropical storm late on December 27.

    The Moderate Resolution Imaging Spectroradiometer (MODIS) on board
    NASA’s Aqua satellite acquired a true-color image of Tropical Cyclone
    Darian on December 27, when the storm was still at Category 1 strength
    with winds near 90 mph (145 km/h). Darian retained a large cloud-filled
    eye with convective bands spiraling into the center, but had become
    asymmetrical due to the effect of wind shear.

    At 10:00 p.m. EST on December 27 (0300 UTC on December 28), the Joint
    Typhoon Warning Center (JTWC) advised that Tropical Cyclone Darian was
    located approximately 967 miles (1,556 km) south-southeast of Diego
    Garcia and was tracking southwestward. Darian’s maximum sustained winds
    were 69 mph (111 km/h) and maximum significant wave height was 28 feet.
    It is expected to continue to weaken and stay over open ocean for the
    next several days.
