    Hongkonger moment

    I’m seeing so many posts about the hurricane meanwhile we get hit by multiple typhoons every year.

    For our tropical cyclone hazard system, most people don’t have to work under typhoon warning signal no. 8, but only if it happens before you get to work.

    There used to be a joke about “Lee’s Forcefield”, where the observatory would often NOT put up no. 8 until after the stock market starts for the day, meaning most people have to work.

    Therefore yes, you’re going to work.

      Not an expert here, but given the differences in measurement scales, I suspect there is a difference in intensity.

      If my reading of this Hong Kong Observatory reference is correct, a no 8 is classified as wind speeds between 63-117 km/h.

      When we talk about hurricane strength, we’re using this scale. Unless they are measuring different metrics, a no 8 is the equivalent of a tropical storm. Which is to say, we don’t even rate that as hurricane strength.

      Helene hit land at around 220 km/h (Cat 4). Milton reached speeds of 260km/h (Cat 5), but might weaken to 190-200km/h (Cat 3) by the time it reaches land.

      Yeah but hong Kong isn’t built on sand out of matchsticks and painted cardboard
