Others have pointed out siblings, but it’s also worth noting that, in the context of your comment, sisters and brothers is more correct. Sibling is more clinical and might be used in a description like “I have 3 siblings, 2 brothers and 1 sister”. When you are addressing a group, the more familiar brothers and sisters is appropriate. “May the force be with you, siblings” would be very weird.
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.
One of the most surreal experiences in my life was riding in an ambulance in Norway and having the EMT sheepishly explain that while the ambulance ride was free, the ER visit was going to come with a bill. He was equal parts embarrassed and indignant about it. The bill was the equivalent of $25.
