Storm summary

An plain-language summary based on HURDAT2 data (free) — plus the full NHC Tropical Cyclone Report PDF if available — appears here in the production version. The summary covers lifespan, track, landfalls, peak intensity, surge and rainfall, casualties, and other notable aspects.

Production behavior: an LLM generates a 4–6 paragraph summary the first time the page is viewed, then caches it. ~$0.001 per storm. The PDF link points at NHC's official report when one exists.
