The storm had wind speeds of up to 120 km/h (75 mph) and was located about 185 km (115 miles) southwest of Hong Kong as of 5 p.m. ET. Further intensification is not expected as the country approaches.
The landfall is expected Tuesday afternoon or evening local time near the city of Yangjiang in southeastern China’s Guangdong province.
A strong wind signal No. 3 was in effect for Hong Kong, indicating wind speeds of 41 to 62 kph (about 25-40 mph) are expected, according to the Hong Kong Observatory’s typhoon warning signals.
Cempaka will bring heavy, flooding rains to southeastern parts of China for much of this week. For Guangdong, Guangxi and Hainan provinces, widespread rain of 100 to 200 mm (about 4 to 8 inches) is forecast. Isolated sites could approach 500mm local time through Friday. There will also be strong, gusty winds, especially on the coast where the storm will make landfall, which could cause isolated power outages.
The Joint Typhoon Warning Center said it expects Cempaka to swing over these provinces this weekend and may reappear over the South China Sea, with an increased risk of rain and flooding, especially near the coast.
