Which hazard drives modeled loss here?

FEMA's modeled annual dollar loss for Alexandria (city) is led by Riverine Flooding (about $26.5M Expected Annual Loss, Historical Loss Ratio Relatively Low), while Strong Wind carries the highest National Risk Index rating (Relatively High). EAL and risk score use different inputs; they need not agree.

What does Alexandria (city)'s hazard record show?

Reading the federal records together

The NFIP claims register shows a middle-volume loss record here: 404 paid claims, totaling $7.2M. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $17.8K average describes payments on recorded claims only, leaving uninsured damage and properties without a claim outside the measure.

The declaration register points in the busier direction. Alexandria (city)'s 22 federal records stand 8% above the Virginia county mean of 20.4. That comparison describes how often federal action was recorded, including any Major Disaster, Emergency, and Fire Management entries shown on this page; it does not convert the count into future probability.

FEMA National Risk Index

This county carries a high composite score on FEMA's National Risk Index, 73.7/100, rated Relatively Low. Its Expected Annual Loss rating is Relatively Low (roughly $40.1M in annualized losses), and a Very Low social-vulnerability profile combined with Relatively Moderate community resilience shapes how much of that raw exposure becomes realized harm. Of the 18 hazards FEMA models, Strong Wind stands out as the sharpest exposure here, rated Relatively High. FEMA's modeled frequency puts that hazard at an average of 8 times per year here, based on 306 historical events on record.

Declaration frequency

The FEMA register is busy by both local and national comparisons. It contains 22 entries for Alexandria (city), including 16 Major Disaster records, 8% above the Virginia county mean. Across the 54-year span, that works out to 0.4 declarations a year. Hurricane leads the file with 5 entries. Declaration type records the federal action taken, not every assistance program approved.

How often does each hazard strike Alexandria (city)?

FEMA's National Risk Index models a historical event count and an annualized frequency for each hazard type. Most hazards are expressed as modeled occurrences per year; FEMA expresses drought and heat-wave frequency as event-days per year. These modeled frequencies are not forecasts.

Strong Wind Relatively High an average of 8 times per year
Heat Wave Relatively Moderate 6.3 modeled event-days per year
Riverine Flooding Relatively Moderate an average of 1.4 times per year

What Hurricane declarations mean here

Hurricane is the most frequent declaration type on Alexandria (city)'s federal record, 23% of its declarations. Atlantic tropical systems run on a defined season, 1 June to 30 November, with most activity concentrated between August and October; Pacific and territorial basins run on their own calendars. A single named storm routinely produces one declaration number covering a long corridor of counties at once, well inland as well as on the coast, which is why an affected county's count can jump by several in one year without several separate events having occurred.

One practical distinction matters when reading these records: a tropical declaration usually bundles wind, storm surge and inland rainfall flooding under a single incident, but the insurance behind them is split. Wind damage falls to property insurers, while flood and surge damage is covered only under a separate National Flood Insurance Program policy. That is why a county can show heavy declaration activity and a comparatively small NFIP claims record, or the reverse.

Declaration counts describe past federal action. They are a record of what was declared, not a forecast of future hazard probability.

The model's sharpest exposure here: Strong Wind

Strong Wind covers damaging non-thunderstorm, non-tornadic wind, the kind produced by steep pressure gradients and downslope events. It is a broad, frequent, low-drama hazard: roofs, signage, power lines and high-profile vehicles, spread across a wide area rather than concentrated on a path.

Worth noting for Alexandria (city): the model and the federal record do NOT point at the same hazard. Strong Wind carries the highest modeled rating (Relatively High), while the county's declaration history is led by Hurricane. That is not a contradiction, the two measure genuinely different things. Declarations record federal ACTION, which requires damage costly enough to exceed state and local capacity; the Risk Index models EXPECTED annual loss across all 18 hazards whether or not any declaration ever followed. A hazard can be the county's largest modeled exposure and never once have driven a declaration.

National Risk Index ratings are modeled estimates of expected annual loss, not predictions of what will happen in any given year.

Data-matched county comparisons

Alexandria (city)'s closest FEMA peer: Yolo County, CA

Comparisons use published FEMA declaration fields plus the National Risk Index composite for Alexandria (city). Record similarity, not a safety rating.

How these peers are chosen

Cohort: Published U.S. county equivalents outside the source state or territory. Each metric keeps six ETL candidates; three unique destinations are shown after de-duplicating across axes. Declaration-volume ranking combines count and Major-disaster share and prefers a different leading incident type; Major-share ranks the Major fraction adjusted for volume; NRI ranks the modeled composite score only.

Data Sources & Methodology

Disaster declaration data comes from the FEMA OpenFEMA Disaster Declarations Summaries v2 API, which includes all federally declared disasters, emergencies, and fire management assistance grants.

Storm event data is sourced from the NOAA Storm Events Database (2015-2025), which tracks significant weather events including thunderstorms, tornadoes, floods, and winter storms.

Flood insurance data comes from the FEMA National Flood Insurance Program (NFIP) OpenFEMA claims dataset.

This data is provided for informational purposes only. FEMA disaster declarations represent federal response actions and may not capture all local emergencies or weather events.

What this means for Alexandria (city)

Alexandria (city), VA has 22 federal declaration records, 8% more than the Virginia county mean of 20; its history sits in PlainHazard's high activity band.

  • Within this above-state-average declaration file, major disaster leads with 16 of 22 records; the category describes past federal action, not the next likely hazard. Virginia overview
  • The state benchmark and national rank point the same way: this count tops the Virginia mean and the totals for 57% of 3,266 U.S. counties. Most-disaster rankings
  • Use the data guide to separate this mid-volume insurance-claims file from declaration counts and modeled NRI risk. Disaster-data guide

An above-average declaration count records past federal responses; it does not predict the next event. Current warnings come from the National Weather Service and local emergency officials.
