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.
