Hurricane outage feature table

A per-(storm, county) feature table for predicting hurricane power-outage impact across the US South-East and Gulf coast, built entirely from public sources. Each row pairs a landfalling hurricane with a county, the county's exposure and its proximity to the storm, and the observed peak number of customers left without power.

Files

• model_table.parquet — the feature table: 27,216 rows (28 storms x 972 counties).
• storms.parquet — the storm catalogue (storm_id, name, year, peak intensity, landfall time).
• exposure.parquet — county exposure (fips, population, centroid lat/lon).

Schema (model_table.parquet)

column	description
storm_id, name, year	storm identity; storm_id is the leave-one-storm-out key
fips	five-digit county FIPS
dist_km	county centroid to the storm's closest track approach
wind_decayed_kt	storm peak wind attenuated by distance: a county-varying exposure proxy
forward_speed_kt	storm mean forward speed
population	county population
max_wind_kt, min_pressure_mb	storm peak intensity
peak_customers_out	label: peak customers without power over the storm window

Sources and licences

Source	Provides	Licence
NOAA HURDAT2	storm tracks, wind, pressure	public domain
ORNL EAGLE-I (Figshare 24237376)	county customers-out, 15-minute	CC-BY-4.0

Coverage is US South-East and Gulf landfalling hurricanes from 2014, when EAGLE-I coverage begins, through 2025.

Construction and limitations

The label is the peak county customers-out over [landfall − 3 days, landfall + 10 days]. Where two same-year storms have overlapping windows, each window is clipped at the midpoint between landfalls so no outage is attributed to both storms. Caveats:

• The label includes routine, non-storm background outages; it is not baseline-subtracted. Counties a storm did not materially affect carry small or zero peaks.
• The label counts customer accounts, whereas population is residents, so a few counties show outages above their population.
• dist_km and wind_decayed_kt stand in for a physical wind-field model, which is not included here.
