What it means for a buyer or owner
In Monroe County, hurricane wind and storm surge tend to arrive together, and the county has taken 26 direct hurricane landfalls. Wind is the part every property shares, so the roof and openings matter as much as the flood zone.
Ask for the roof's age and permit, any shutters or impact-rated windows, and a wind mitigation report.

Coastal flooding and storm surge
Very HighThe local numbers
- FEMA rates coastal flooding risk in Monroe County "Very High" (score 98.8 of 100, compared with every U.S. county).1

What it means for a buyer or owner
With 93.2% of Monroe County's building value in FEMA's coastal flood areas, check three things before you buy: the flood zone (VE and Coastal A zones carry the strictest building rules), the ground and floor height against the base flood elevation, and the storm-surge evacuation zone.

Inland flooding
Relatively LowThe local numbers
- FEMA rates inland flooding risk in Monroe County "Relatively Low" (score 42.9 of 100, compared with every U.S. county).1
- Expected damage to buildings: about $4.6 million a year, the 47th-highest expected building loss from this hazard of 67 counties in the state.1
- FEMA's index maps about 24 square miles of the county inside the 1%-annual-chance floodplain it uses for inland flooding.1
- 15 inland flood events in FEMA's record, about 0.5 a year.1
What it means for a buyer or owner
Beyond the roughly 24 square miles of mapped floodplain in Monroe County, rain-driven flooding follows rivers, lakes, wetlands and canals, and it doesn't stop at the mapped lines: FEMA says more than 20% of flood insurance claims come from outside high-risk areas.
Ask whether the home has flooded or had a flood claim, and look at the lot's elevation in the report.

Tornadoes
Very LowThe local numbers
- FEMA rates tornado risk in Monroe County "Very Low" (score 25.6 of 100, compared with every U.S. county).1

- 61 tornadoes recorded in the county in FEMA's index (NOAA Storm Prediction Center records), about 1.1 a year.1
- 1 federal disaster declaration for tornadoes.3
What it means for a buyer or owner
With roughly 1.1 tornadoes a year on record, Monroe County sees mostly brief, narrow touchdowns, often spun up by tropical systems and spring squall lines, so damage is very local. The same roof-to-wall connections that resist hurricane wind help here.
Check the roof covering, any hurricane straps or clips, and the insurer's windstorm deductible.
