It is quite rare to have 3 typhoons around the vicinity in HK. Fortunately, we were 'spared' of their awesome destructive powers as they made landfall in our neighbouring lands. It's a blessing some will take for granted.
I still remembered once when we were hit by Typhoon York several years ago and that was extremely scary. Recalling how my skyscraper swayed from side to side and how the wind actually "sucked" the windows wide open was too much for me. Thereafter, all my windows are secured by wired ties even on normal days.
While different areas may show different physical phenomenon, a typhoon in our vicinity will always cause smog to cover the island and the air very still. After the typhoon is over, the air will be good. Recently we had a typhoon and a T3 signal was raised. But the wind I experienced at TST pier was as bad as that of a T8!!
Last few days, we are seeing nice blue skies. It's not very often that one sees nice blue skies in Hong Kong. Visibility is usually bad - and so bad that the scenery is "washed grey".
