GetStormRisk

Live hurricane tracking with personalized address risk for the Atlantic season.

About

GetStormRisk is an independent hurricane tracking platform that aggregates NHC advisory data into a fast, map-first dashboard with personalized address risk. During the Atlantic hurricane season (June 1 – November 30), it provides real-time tracking of named storms with cone and track overlays directly from the National Hurricane Center.

The competitive edge is personalization: you can check your specific address against the current NHC forecast cone and get email alerts before a storm approaches — not after it's already in the news.

Why I Built This

My name is Yoni Binstock. I built GetStormRisk because the raw forecast map is commoditized — NHC, Weather.com, and CNN all have one. What's missing is personalization: knowing whether your address is in the cone, and being alerted before the storm is already on the news cycle.

How GetStormRisk Works

Where the data comes from

All forecast data originates from the National Hurricane Center (nhc.noaa.gov), operated by NOAA. GetStormRisk pulls two NHC sources: the CurrentStorms.jsonfeed for active storm metadata and the GIS forecast cone and track shapefiles per advisory. Data is ingested every 15 minutes during active storms and every 6 hours off-peak — matching NHC's advisory cycle with minimal lag. GetStormRisk is not affiliated with NOAA or NHC; it is an independent aggregator.

How address risk is calculated

When you enter an address, GetStormRisk geocodes it and runs two checks against the latest NHC advisory data: (1) a point-in-polygon test against the official NHC 5-day forecast cone GeoJSON to determine whether the address falls inside the cone, and (2) a nearest-point distance calculation from the address to the forecast track line. These estimates are approximations — storm surge, local topology, and wind radii vary significantly from the cone geometry. NHC is the authoritative source for all hazard determinations; GetStormRisk is an early-awareness tool, not a safety system.

How alerts work

When GetStormRisk ingests a new NHC advisory, it checks every saved address against the updated forecast cone polygon. If the NHC cone intersects a saved address within the user's configured threshold distance, an email alert is sent via Resend. Alerts are strictly deduplicated per advisory — one alert per NHC advisory issuance per saved location, regardless of how many times the cron runs. There is no spam: if the cone doesn't move, no alert fires.

Methodology

Address risk is computed using the NHC 5-day forecast cone polygon. A point is flagged “in cone” when it falls within the GeoJSON polygon distributed by NHC. Distance-to-track is the nearest-point distance to the forecast track line. Wind category estimates at distance are rough approximations based on typical wind radii — they are not official and should not be used for safety decisions.

GetStormRisk never fabricates, interpolates, or smooths forecast data. Only what NHC issued is shown, with the source advisory ID and issued timestamp on every view.
