    Tropical Storm Chaba formed from a tropical depression over the South
    China Sea on June 29, 2022. Initially named Caloy by the Philippine
    Atmospheric, Geophysical and Astronomical Services Administration
    (PAGASA), the system was also dubbed 04W by the Joint Typhoon Warning
    Center (JTWC) and, as the storm strengthened and moved westward, the
    Japan Meteorological Agency gave it the designation Tropical Storm
    Chaba.

    On June 30, the Moderate Resolution Imaging Spectroradiometer (MODIS)
    on board NASA’s Terra satellite acquired a true-color image of Tropical
    Storm Chaba as it was strengthening and moving towards mainland China.
    At that time, the cloud-filled eye was indistinct, and the western side
    of the system was bringing rain to Vietnam while the eastern edge of
    Chaba was interacting with parts of the Philippines.

    Later that evening, at 2100 UTC (5:00 p.m. EDT), the JTWC advised that
    Tropical Storm Chaba was carrying maximum sustained winds of 46 mph (64
    km/h) and gusts up to 63.3 mph (102 km/h). The center of the storm was
    located about 326 miles (525 km) south of Hong Kong and was tracking
    northwestward.

    Tropical Storm Chaba is heading towards environmental conditions
    favorable for strengthening and is predicted to make landfall east of
    the Luichow Peninsula as early as late on July 1. The JTWC expects the
    storm to achieve maximum sustained winds of 75 mph (121 km/h) before
    coming ashore. This would be the equivalent of a Category One storm on
    the Saffir-Simpson Hurricane Wind Scale. The JTWC also notes there is
    also a risk of rapid intensification during the next 24 hours. However,
    as Chaba interacts both with the island of Hainan and then mainland
    China, it will begin to degrade. It is expected to dissipate a day or
    two after landfall as it moves northward over China.
