Last time I checked there was no Florida Hurricane this month, pls resolve

Unless a hurricane magically appears in the Atlantic Ocean within the next 3 hours off the coast of Florida, I think this market can easily be resolved as NO

Seems like this market has moved up a bit based on Hurricane Lee heading in Florida's general direction, but as far as I can tell, hurricanes coming from this direction almost always turn northward, no?

@partlygloudy Correct. Lots of people bet based on vibes.

There's currently a combined 71% chance that a hurricane will hit either Florida or the Carolinas and a 66% chance that one will hit anywhere in the mainland US. Get your act together, folks.

@NicoDelon 🔮

For arbitrage, /NicoDelon/will-a-hurricane-make-landfall-anyw-febe1d6f3eb0 should be strictly higher than this one.

So uh…

@CoryS September is typically the most active month but we're basically getting our September hurricane right now, at the cusp of September. If you look at records it seems relatively uncommon to have two hurricanes (not TS) hit Florida within a month (2004 was wild!).

@NicoDelon if the stats bear out that FL gets one per month and usually not more, then this is not “basically our September hurricane,” it is an August hurricane, from the standpoint of statistics. We shall see, though.

@CoryS the calendar month is irrelevant. If one hit in September this would still make roughly two hurricanes within a month, and that's I'm saying is rare in the records (it happens, just not 75% of the time).

@NicoDelon It's happened 11 times in the last 100 years to have two hurricanes within a big month (35 ish days) between August and October.

Could you confirm that you will not count the tail of a storm as 'hitting Florida'. So, for instance, if Idalia hasn't completely left Florida by September 1, that wouldn't count since it made landfall in August. Correct?

@NicoDelon good question!

@NicoDelon Yes, that's correct.

@AliciaGrugett thanks

@AliciaGrugett What if it exits florida into the atlantic and then curves back to hit a second time in Sept?

@RyanGuill Then, I guess that would count, if it came back and hit a second time, independent of the first strike.

@NicoDelon Well, I didn’t really think it would happen…but I would have counted it, if it did. :-)

@AliciaGrugett I know and that would be fair. Just noting that fewer models are now making it loop. Could still happen but increasingly unlikely.

@AliciaGrugett Can you specify what you mean by hit (landfall via positioning of center, or some other measure such as observations of sustained winds in Florida) and what sources you will use. Also, if it is unclear at resolution time will you wait for something like best tracks ( if you go by landfall) or rely only on advisories?

@parhizj Landfall of the eye of the storm, confirmed by the National Hurricane Center.

@AliciaGrugett NHC landfall goes by positioning of the center of the storm and interpolating between time samples to determine that, not by the “eye”. And it has at least three different ways to provide that information: advisories/discussion, in preliminary best track, and in best tracks…. Each take different amounts of time to resolve

@parhizj “A storm is considered to have made landfall when a storm’s eye crosses the shoreline”-meaning the entire eye has passed the shoreline. This can be 5 miles to 120 miles across. This is the criteria I will use.

@parhizj My previous comment is based on the National Hurricane Center info.
