Local meteorologists say that the no. 1 typhoon signal will be hoisted in Macao at 4:30 pm as a tropical depression comes within 500 kilometres of the city.
According to the Meteorological and Geophysical Bureau (known by its Portuguese initials SMG), the tropical depression is expected to move toward areas between western Guangdong and Hainan Island within the next one to two days.
Affected by its circulation, Macao will gradually experience cloudy and windy conditions from late Wednesday to Thursday, with occasional showers and thunderstorms, the SMG says.
