Tropical Storm Narra formed in the Gulf of Tonkin on Saturday and could prompt Hong Kong to issue a tropical cyclone warning signal early next week, the Hong Kong Observatory said.
The storm was about 290 kilometers (180 miles) west-northwest of Haikou at 10 a.m. Saturday and moving slowly, the observatory said. It was expected to remain over the Gulf of Tonkin through the day before turning east-northeast early next week toward the Leizhou Peninsula and western Guangdong.
Forecasters said they were monitoring Narra’s track and local wind conditions to determine whether a warning signal would be needed.
Narra is forecast to move across waters north of Hainan Island on Tuesday and weaken to a tropical depression as it approaches the Leizhou Peninsula and western Guangdong on Wednesday. It could pass within 400 kilometers (250 miles) of Hong Kong by Thursday.
The observatory said the storm could bring heavier rain, squally thunderstorms and strengthening winds to coastal areas from early to midweek.
Hong Kong is expected to see cloudy conditions and scattered showers Sunday, with more localized heavy rain and thunderstorms later in the day. Temperatures are forecast to range from 27 to 31 degrees Celsius (81 to 88 degrees Fahrenheit).
A broad low-pressure trough is also expected to keep weather unsettled along the southern China coast and in waters east of Taiwan in the coming days.
