June 28, 2025 - Tropical Depression Delivers Second Blow to Storm-battered Hainan Island
Tweet
On June 25, 2025, a monsoonal low area over the South China Sea strengthened into a tropical depression east of China’s Hainan Island. It was named Tropical Depression 03W and carried maximum sustained winds of about 30 miles per hour (48 km/h), with the Joint Typhoon Warning Center (JTWC) expecting little change in strength before landfall. By late that same day, the small but rain-filled system made landfall over northeastern Hainan Island and then made a second landfall on mainland China’s Leizhou Peninsula. It then dissipated on June 26 as it moved inland.
While the winds carried by the tropical depression were not destructive, the soaking rains added to severe flooding brought to Hainan by Typhoon Wutip, which battered the region from June 12-15. According to multiple media reports, Wutip not only dumped record rainfall in some locations, widespread flooding damaged roads and croplands. Five people were reported to have died and hundreds of thousands had to be evacuated from the hardest-hit regions.
The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite acquired this true-color image of Tropical Depression 03W on June 26. At that time, the center of the system was moving over the Leizhou Peninsula yet the southern section of the storm still lingered over Hainan Island, bringing continued rainfall.
