The Bureau of Meteorology and Geophysics (SMG) will issue Tropical Cyclone Signal No. 1 this evening as Typhoon Mahon is expected to come within 800 kilometers of Macau, according to the Bureau of Meteorology.
A tropical cyclone is now passing near Luzon in the Philippines and will approach the west coast from central Guangdong province tonight and tomorrow, posing a “substantial threat” to the Pearl River Delta region, including Macau, SMG said. .
The bureau added that Mahon’s forecasted trajectory could be adjusted westward, so there would be a higher chance of storm surges in Macau if it landed west of Macau.
