Tropical Storm Lionrock nearing Hong Kong

Tropical storm Lionrock is close to Hong Kong, approaching, and strenghening - so might become Typhoon Lionrock.

Somewhat ironic it has name chosen by Hong Kong, and (of all places a storm with this name could have chosen) looks set to affect us.

Currently, sunny and hot in Hong Kong. But radar on HK Observatory site shows the outer rainbands of the storm are nearby, and edging closer.

Scenes from Cheung Chau, Hong Kong, as Typhoon Koppu approached and passed Hong Kong

Typhoon Koppu passed Hong Kong over 14-15 September 2009; came within around 120km (to southwest) overnight. Major thunderstorm the evening before - see this video. In post below this, there is video from Cheung Chau, on 14th and 15th.

It was very hot on 13 September - to 34.5C on Cheung Chau; after hot few days following Hong Kong's hottest August since 1963. With a tropical storm forming near Luzon, and headed towards Guangdong, seemed thunderstorms were likely. Even so, this storm was remarkably severe - for amounts of lightning, and tremendous thunderclaps. Phew!

Tropical Storm Goni aims for Hong Kong

Note on 8 Aug: Goni still of some interest: it earlier passed us, turned left at coast, weakened, moved to sea again, and now near Hainan, rated tropical storm again by HK Obs.
One forecast - from ECMWF - has it heading our way again, for around 3-4 days time...

 

Tropical Cyclone Molave aims for Hong Kong

Tropical depression Molave has strengthened to become a typhoon (as I edit at noon on 17 July, around 350km ese of HK), and now on course towards Hong Kong. Looks set to hit early on 18 July.[Note on 19 July: it passed just to north of HK, across Shenzhen.]

Tropical Cyclone Hagupit and Hong Kong

Just seen forecast for Tropical Storm Hagupit; and Joint Typhoon Warning Center track is "interesting" - ie, could become pretty powerful typhoon, and head to somewhere around (or over) Hong Kong.

Edit: indeed proved "interesting" - one of the strongest storms (or the strongest storm) to affect Hong Kong in recent years. Moved west across sea to south of Hong Kong, approaching to within 180km (roghtly the distance as I edit this, with winds at Cheung Chau severe storm force to almost hurricane force; night time, so not good for photos/video). Here's some video I shot this afternoon - winds stengthened quickly from lunchtime; waves built up rapidly too.

Here's some video from Cheung Chau this morning, including winds/rain as eye making landfall around 300km wsw of Hong Kong, and some coastal damage on Cheung Chau:

Severe Tropical Storm Kammuri

kammuri surf

Severe Tropical Storm Kammuri just hit Hong Kong; not direct, but caused gales n storm force winds, and Number 8 signal in force for much of daytime today, 6 August.

 

I took this yesterday, at Shek O - Kammuri still brewing, and some distance away, but good swell, w surf on rocks.

Severe Tropical Storm Fengshen heads towards Hong Kong

Severe Tropical Storm Fengshen - which had hit Philippines as a typhoon, killing several hundred people (mainly in ferry that sank) - was forecast to head towards Taiwan. But now, looks to be coming roughly straight for Hong Kong. HK Observatory has issued Number Three signal.

Pabuk

Severe Tropical Storm Pabuk looked set to have passed Hong Kong, barely causing an impact other than a pulse of thunderstorms, some rain. Headed towards Hainan, and forecast to dwindle to nothingness. But, it stopped, strengthened again, and turned around - and headed straight for Hong Kong as a tropical storm, hitting on 10 August; seems the rather hazy centre hit Lantau, before it moved off towards west, and weakened..
Led to hoisting of Number 1 and then, a couple of hours or so later, the Number 8: latter causing massive confusion, as people scurried home from work.

Here are views from Cheung Chau, as Pabuk approached (again!), and as it came close, with intense rainband.


This windspeed chart from Cheung Chau weather station shows the wind peaked roughly as I took the above photo, at around 100km/hr (10-minute average): storm force, tho soon down to gale force.

 

I had to take a ferry. As I neared the pier, passed bicycles blown over by powerful wind, and this broken tree branch.

The ferry took 15-20 minutes just to leave the pier! - blown against it by the wind!
Even in the typhoon shelter, the gale to storm force wind was blasting small waves w white water. Here, took shot in pelting rain.

There were big waves - some 3-4 metres? - soon after the ferry left the typhoon shelter. The ferry took an unusual course, to avoid as much as possible the roughest seas towards Hong Kong - north past Hei Ling Chau, to pass near Peng Chau. Even so, once we were beyond the lee of Hei Ling Chau, the ferry rolled in big seas; a few times, rolled pretty far then hit by waves that sent spray to windows of middle deck (where I was).
I shot these clips, inc as arrived in Victoria Harbour.

Calmer in the harbour, tho some dark clouds moved over.

I arrived in Central to find large crowd of people, waiting to catch ferry to Cheung Chau. (and go home - not for holiday!) The Number 8 was imminent, or up already.

Took quite some time for ferries to arrive. When a small - two deck - ferry berthed, there was degree of chaos as people rushed along exit way, dashed onto ferry without paying, w much shouting. But then, gate closed behind them, and things quiet again: the ferry left, and I figured I was glad not to be on it, as surely would bounce even more than three-deckers (as I'd come in on).

There were tv news crews around, reporting on people waiting for ferries. (Maybe, too, on the storm - but in Central it was pretty quiet; hard to guess how rough the seas were towards Cheung Chau, and how strong the wind had been there.)


Later, I came back to the ferry pier - sure the Number 8 must go down soon, and wanting to take ferry home (as little to do in town after collecting my family; we'd had coffee, eaten, been to supermarket, waleked by closed shops, checked HMV, and now just waiting, waiting and waiting at the pier). Boring, tho the harbour looked attractive w reflections on water free of boats: rather frustrating to be waiting like this when the harbour was calm as a mill pond!

THe piers were near deserted; a few others waiting for ferries and - as here - still a few news crews hanging on.

At last came annuncement that Number 8 replaced by Number 3; ferries didn't start at once; Lamma ferry off before Cheung Chau one even appeared), but we could eventually head home - phew!

HK Number 8 Signal

Hong Kong's Number 8 tropical cyclone warning can be controversial; the signal means that gale force winds are expected or blowing in Victoria Harbour. Especially as this may mean hurricane force winds may soon follow - as the eye of a typhoon approaches - this signal can prompt a virtual shutdown of Hong Kong.

But, hurricane force winds rarely follow; and there have been occasions when the Number 8 has been issued, then little happened bar strong winds and rain - and business folk have complained about the city shutdown causing economic losses they believe are unnecessary.

Hearing a discussion about Hong Kong's tropical cyclone warning signals on RTHK Radio 3 recently, I emailed to suggest that there might be two signals when gales are due: a Number 8 if stronger winds don't seem imminent, and another signal if there appears to be a chance that the winds will reach and then surpass gale force. Dr Wong of the Hong Kong Observatory, who was on air at the time, thanked me for my suggestion but said we already have the second signal - the Number 9. But, the Number 9 is issued only when gales are blowing and increasing, not before gales have started; I emailed the Observatory to say so, and this led to the following correspondence.
