HAIKOU/GUANGZHOU, Aug. 23 (Xinhua) -- South China's Hainan and Guangdong provinces have been placed on alert as Typhoon Kajiki, the 13th typhoon of the year, is forecast to bring gales and rainstorms.

At 11 a.m. Saturday, Hainan activated a Level IV emergency response for flood and typhoon control, as strong winds and downpours are expected to hit its sea areas and island, according to the provincial disaster prevention, mitigation and relief commission.

Meanwhile, Guangdong's headquarters for flood and typhoon control and drought relief launched a Level IV emergency response for typhoon control, as the province's waters saw strengthened winds.

According to Guangdong's provincial meteorological observatory, heavy rains and strong winds are forecast to sweep the Leizhou Peninsula and the coastal areas of the cities of Maoming, Yangjiang and Jiangmen between Sunday and Monday.

Typhoon Kajiki developed from a tropical depression over the South China Sea on Saturday morning. At 8 a.m., its center was located around 770 kilometers east of Hainan's Sanya City over the sea, with a maximum wind speed of 18 meters per second and a central pressure of 998 hectopascals.

The typhoon is forecast to continue moving in a west-northwest direction at about 25 kilometers per hour, with its intensity further strengthening. It is likely to make landfall or pass close to the southern coast of Hainan Island around Sunday evening, before heading toward the central and northern coastal regions of Vietnam. ■
