Storm Danas in Hong Kong

Heavy rainfall in Mui Wo, Lantau

A friend in Hong Kong told me about the "crazy thunder and lightning" where she was in Mui Wo, on Lantau Island, and the incessant rain has resulted in the authorities announcing there would be no day school tomorrow, Friday.

That's a first -- usually local officials don't decide until the morning of, leaving parents bleary-eyed watching the storm updates until late at night in a bid to anticipate if there's school the next day or not.

Storm Danas is moving across Guangdong, causing heavy rains and thunderstorms. This morning there was an amber rainstorm warning posted at 8.35am, which turned red, then back to amber at 10.40am, then back to red again two hours later.

"The active southwest monsoon to its south will generally affect the vicinity of the Pearl River Delta [on Thursday and Friday]. There will be torrential rain and squally thunderstorms over the area," The Observatory said.

It warned residents outside to seek safe shelter as soon as possible.

Hopefully there won't be too much flooding or severe damage in the next 24 hours, but it does sound like rain coming down in Biblical proportions...
