Florida Hurricanes, Measured: $19.3 Billion in Flood Claims, 41% of It in 2024

Part three of three. Part one counts hurricanes city by city; part two counts FEMA declarations.

Declarations and storm counts say where hurricanes went. Flood insurance claims say what water did when it got there. FEMA publishes every National Flood Insurance Program claim, anonymized, with the year of loss, the census tract, the flood zone and the amount paid. For Florida, 1978 to 2024, that is 447,683 claims and $19.29 billion paid.

The costliest years

Year of loss	Claims	Paid	Main storms
2024	80,439	$7.88B	Helene, Milton
2022	50,323	$4.95B	Ian, Nicole
2004	34,726	$1.25B	Charley, Frances, Ivan, Jeanne
2017	31,430	$1.03B	Irma
2023	10,299	$0.66B	Idalia
2005	32,420	$0.63B	Dennis, Katrina, Wilma

2024 alone is 41% of everything the program has paid in Florida since 1978. 2022 and 2024 together are two thirds of it. Even before adjusting for inflation, which these figures do not, the last three years have reset the scale.

By county

County	Claims	Paid	Average claim
Lee	48,456	$3.96B	$81,614
Pinellas	51,897	$3.75B	$72,242
Hillsborough	18,447	$1.18B	$63,851
Collier	14,750	$1.13B	$76,606
Sarasota	14,408	$0.85B	$59,292
Miami-Dade	61,977	$0.85B	$13,757
Escambia	16,419	$0.72B	$43,934
Monroe	27,423	$0.71B	$25,839

Lee and Pinellas are 40% of the state's total. Ian's surge in Lee (2022) and Helene's and Milton's in Pinellas (2024, $3.37 billion in that year alone) drove them. Lee, Collier and Pinellas have the largest average claims of any Florida county with more than a thousand claims, each over $70,000.

Miami-Dade has the most claims and a small average. 61,977 claims, more than any other county, at $13,757 each: many floods, mostly shallow. Surge and rainfall flooding are different perils with different bills, and a county's average claim tells you which one it mostly gets.

Outside the high-risk zone

Of Florida's claims, 14.6% came from properties in zones X, B or C, outside FEMA's mapped high-risk flood area, and they received 8.0% of the dollars. In Volusia County, 28% of the money went outside the mapped high-risk area: 24% of its 2022 payout, the year of Ian's inland flooding, and 31% of 2024's. A flood zone is a statement about probability, not a promise.

What the record cannot tell you

Only insured losses. NFIP pays policyholders. A flooded home without a policy is not in this data, so these are floors on flood damage, not totals. Policy counts are not published alongside, so nothing here is a rate.

Nominal dollars. A 2004 dollar is not a 2024 dollar. The comparison across years understates the older losses.

Year of loss, not year of storm. Claims are filed by the date of loss; a late-season storm's claims all land in its year.

Calchis draws these claims onto every Florida county page and uses them, tract by tract, in its flood scoring, alongside FEMA's flood zones and USGS ground elevation.
