The Meteorological and Geophysical Bureau (SMG) insisted that it was necessary to hoist the No. 8 signal for Severe Tropical Storm Nangka despite the fact that the typhoon was located over 400 kilometres away from Macao at the closest.
Signal No. 3 was hoisted at 8 pm on Monday as tropical storm “Nangka” was about 440 kilometres south of Macao as it was heading towards Hainan, and with a northeast monsoon lurking in the South China Sea, the possibility of issuing the Typhoon Signal No. 8 at dawn was “medium to relatively high”, the local weather station forecast late last night.
Serious flooding forecast for Wednesday in low-lying areas, resident evacuations started Tuesday night
The Meteorological and Geophysical Bureau issued the third level of a storm surge warning that the flood level is forecast to reach between 1 metre and 1.5 metres above the road level in the Inner Harbour area.
