Hurricane Helene will be more costly than Hurricane Milton

[image]Helene came in at $30B in claims, Milton estimated at $30-50B, mostly due to demand surge, where builders have to pay extra to get supplies as local sources have been tapped out for Helene repairs. Milton hitting a more occupied area also played a role.

This will be Resolved two weeks after Hurricane Milton has been downgraded below a Tropical Depression based on which storm has a higher estimated total cost of damages, according to Wikipedia.

If there’s a range of damages, this will look at the top of the range for both storms. If this is a tie, it will Resolve NO.

@mattyb if you were to resolve today, would the information available on Wikipedia be sufficient?

bought Ṁ100 NO

@WilliamGunn Yeah the odds on this question seemed shocking to me initially given just the property values and density of where milton made landfall compared to helene.

but i always assume there's something idk still, im. neg on this app for a reason lol. maybe one of those considerations is that because florida is more hurricane prepared(?)

What if places were damaged in Helene and then not fixed but then damaged in Milton as well? Who gets "credit"? They barely had time to fix anything. Seems very tricky.

@EmilyBemily i assume that’s complexity that the damage assessors will be tackling

Are you using insured damages or estimates of uninsured damages or both combined?

@Pjfkh i’m using Wikipedia. Wikipedia is using this:

In 2018, Roger A. Pielke Jr. and Christopher Landseapublished a peer-reviewed study in the scientific journalNature Sustainability, which gave an estimate of the direct economic losses in the continental United States from 1900 to 2017 from each hurricane if that same event was to occur under contemporary (2017) societal conditions.[8] The general formula for normalized losses is

{\displaystyle D_{2018}=D_{y}\times I_{y}\times RWPC_{y}\times P_{2018/y}}

where is reported damage in current-year US dollars, is the GDP deflator for inflation adjustment, is an estimate of current-cost net stock of fixed assets and consumer durable goods to capture changes in real wealth per-capita, and county population adjustment.

@mattyb Wikipedia doesn't seem to show the normalized cost for hurricanes after 2017. Also, it seems like the nominal cost comes from reporting, and these reports can vary wildly even for the same hurricane:

https://www.insurancebusinessmag.com/us/news/catastrophe/moodys-rms-estimates-11-billion-in-private-insured-losses-from-hurricane-helene-508750.aspx
The wiki page seems to mostly use insured losses, but for some hurricanes it seems to use uninsured losses. From the source for Hurricane Ida:

As a clearer picture of Ida’s devastation emerged, the hurricane likely caused $50 billion to $60 billion in total damage, estimated Karen Clark, who has calculated catastrophic risk since 1987. Her risk modeling company, Karen Clark and Company, figured just $18 billion of those losses would be insured.

Ida is listed at $75.2 billion in nominal damage

@Nightsquared Have the people managing the hurricane page said how they choose what source to use?

@Nightsquared @traders reading through the Wiki comments, they seem to use a variety of sources.

i think relying on the same source for estimates of the damage makes sense, and should be fair. i’ll likely consult a few sources to see how they report the damage from both storms (Wikipedia included). if there’s no clear consensus of which did more damage, i may resolve this to 50:50.

does anyone object to that?

Is anyone seeing it this? This is Florida devastation photo sent from a friend down there, heartbreaking.

"She said during a news conference this morning the fact that Tampa didn’t see the predicted storm surge, “saved a lot, that’s what we were really worried about,” but added that the risk of flooding was not over."

I assume you'll use the "normalized" column from the table on Wikipedia? (Adjusted for inflation and other things.)

@tmk both of these storms are from this year, I don’t see any adjustments for inflation being necessary.

How will you estimate the total cost of the damages? Flesh out the resolution criteria a bit more, and we can sweepify this!

@SG added, cheers!

@mattyb can we not incentivize edit wars?

@nikki yea don’t piss off the Wikipedia review people. i very much appreciate them

@mattyb there's now a $100 incentive to bribe some admin

@nikki you think you can defeat an army of internet weather nerds?
