From HK Observatory:
This means that a tropical cyclone now centred within about 800 kilometres of Hong Kong may affect us.
At 10 p.m., Tropical Storm Doksuri was estimated to be about 750 kilometres east-southeast of Hong Kong (near 20.0 degrees north 121.0 degrees east) and is forecast to move west-northwest at about 25 kilometres per hour entering the South China Sea.
According to the present forecast track, Doksuri is expected to move closer to the south China coastal areas tomorrow (29 June, Friday). Local weather will deteriorate later tomorrow and on Saturday with squally showers and winds strengthening.
As Doksuri is still at a distance from Hong Kong, the chance of issuing the strong wind signal, No.3 tomorrow morning is not high.
