Hurricane Andrew

The storm

Andrew left the African coast as a tropical wave on August 14, 1992, and nearly died twice crossing a hostile Atlantic. On August 22 it found warm water and low shear east of the Bahamas and intensified from tropical storm to Category 4 in 36 hours.

It crossed the northern Bahamas, then struck the Florida coast near Homestead at about 5 a.m. on August 24. NOAA's 2004 reanalysis upgraded the landfall to Category 5 — sustained winds near 165 mph, gusts higher, central pressure 922 mb, the third-lowest U.S. landfall pressure on record at the time. Peak intensity was about 175 mph.

Andrew was compact and fast-moving. The destructive core was roughly 25–30 miles wide, and the storm crossed the peninsula in about four hours. Storm surge reached 16.9 ft at the head of Biscayne Bay — a Florida record at the time — but wind, not water, did most of the damage. Rainfall was modest for a major hurricane (generally under 8 inches) because of the storm's speed. Andrew went on to a second U.S. landfall in south-central Louisiana on August 26 as a Category 3.

The damage

The wind field centered on Homestead, Florida City, and the Country Walk and Naranja areas of southern Dade County. Per the NHC preliminary report, roughly 25,500 houses were destroyed and more than 101,000 damaged in Dade County. About 99 percent of the mobile homes in Homestead were destroyed. Homestead Air Force Base was effectively leveled. Some 1.4 million customers lost power. Sixty-five deaths were attributed to the storm (26 direct).

The failure pattern became a national case study. Roof sheathing attached with staples instead of nails peeled off first; once the roof deck opened, wind-driven rain destroyed interiors and internal pressurization blew out gable ends and garage doors. Post-storm engineering surveys found widespread construction that did not meet the South Florida Building Code then on the books — a code-enforcement failure, not just a code failure. Unprotected windows and doors turned into breach points for debris.

Total damage: $27.3 billion nominal — the costliest U.S. natural disaster to that date.

The insurance aftermath

Insured losses reached $15.5 billion (Property Claim Services, nominal) on more than 650,000 claims — roughly four times what most insurers had modeled as their worst-case Florida hurricane. Before Andrew, no U.S. catastrophe had exceeded $5 billion insured.

The market broke. At least eight insurers became insolvent as a direct result — seven Florida-domiciled companies and one foreign insurer — and others survived only through capital transfers from parent companies. (Counts in later retrospectives range as high as eleven; the count depends on how "technically insolvent" carriers are treated.) The failed carriers left more than $400 million in unpaid claims to the Florida Insurance Guaranty Association, which had to double its assessment rate on surviving insurers to cover them.

Surviving carriers then tried to leave. Insurers announced plans to cancel or non-renew hundreds of thousands of Florida policies, and the state answered with a moratorium on mass cancellations. The structural fixes followed in rapid sequence:

• 1993 — Florida Hurricane Catastrophe Fund (Fla. Stat. 215.555): state-run reinsurance backstop so carriers could buy hurricane cover the private reinsurance market was no longer willing to sell at pre-Andrew prices.
• 1993 — residual market: the Florida Residential Property and Casualty Joint Underwriting Association was created for homeowners who could not find coverage; in 2002 it merged with the wind pool to form Citizens Property Insurance Corporation, still the state's insurer of last resort.
• 2002 — statewide Florida Building Code, replacing the patchwork of local codes, with the strongest wind provisions in the country for the High-Velocity Hurricane Zone (Miami-Dade and Broward).

Andrew also created the modern catastrophe-modeling industry. Rating agencies and regulators began requiring model-based hurricane exposure management, and Florida established a state commission to certify the models used in rate filings.

For policyholders on the ground, the claims experience previewed every large Florida storm since: a shortage of adjusters, months-long waits, disputes over scope (full roof replacement vs. repair), and carriers that failed mid-claim, converting insurance claims into guaranty-association claims with statutory caps.

What policyholders learned

• Insolvency risk is real. Policyholders of the eight failed carriers recovered through the guaranty association — slower, capped, and paperwork-heavy. Financial strength ratings became something Florida homeowners actually checked.
• Code-upgrade costs were a fight. Rebuilding to current code cost more than like-for-like repair; policyholders without ordinance-or-law coverage absorbed the gap. The dispute pushed ordinance/law coverage into standard Florida policy discussions.
• Scope disputes decided payouts. The recurring argument was repair vs. replace on roofs and interiors. Policyholders who obtained independent contractor estimates and engineering opinions — rather than accepting the carrier adjuster's scope — documented the larger losses.
• Photo-and-inventory documentation won claims. With whole neighborhoods flattened, contents claims turned on pre-storm proof. Households with photos, receipts, or video of the home's contents settled faster and fuller than those reconstructing inventories from memory.
• Underinsurance surfaced at the worst moment. Dwelling limits set years earlier didn't match 1992 reconstruction costs, and post-storm demand surge inflated those costs further. Replacement-cost adequacy became a standard annual policy-review item.
• Adjuster churn hurt continuity. Files passed between out-of-state catastrophe adjusters. Policyholders who kept their own written log — every call, name, date, and promised action — could enforce commitments that otherwise disappeared between adjuster handoffs.
