Tropical Storm Nangka is approaching the South China coast; arouhd 320 km to southeast of us just now. Might be pretty close to Hong Kong.
Quite a small storm, by the look of it, though looks set to bring a lot of rain tomorrow. At Weather Underground forum, there's speculation it could intensify.
T1 in effect; as I write this, just had short but heavy shower on Cheung Chau; HK Obs radar shows rather diffuse but thickening rain band passing westwards over HK and sea to south; storm proper yet to show up on the radar.
