Validate Against History
Demonstrate example pay-outs for past storms and validate pricing for parametric insurance. Calibrate historical claims against hazard for internal views of risk.
HWind Real-Time Analysis
Real-time tropical cyclone data leading up to, during, and following landfall.
5-day forecast track scenarios, footprints, and losses made available up to every 6-hours once an Atlantic tropical cyclone is named
Instantaneous views of the tropical cyclone track and hazard characteristics produced every 6 hours throughout the storm’s life cycle
Wind field footprint produced on a rolling, cumulative basis every 6 hours over the lifetime of the storm, leveraging all preceding snapshot analyses
Full wind field footprint and track produced 1-3 days after landfall, based on expert review of all available data used during and after the event

HWind Enhanced Archive
A catalog of 25+ years of high-resolution images, snapshots, and footprints from historical hurricanes
Same HWind Framework
Informed by the same underlying science as the HWind Real-Time Analysis offerings
Incorporates new, revised, or reprocessed data sources and track information made available after the event
Informed by additional analysis iterations to match observational data and create the best representation of a storm’s track and hazard profile over time
Library is updated annually as new data becomes available and new storms occur
Real-Time Insights for Fast Parametric Pay-Outs
HWind cumulative footprints are finalized shortly after landfall enabling fast, reliable pay-outs of parametric insurance contracts. Typically based on observational data they can capture complex features in storm structure. Wind hazard is represented on a high resolution 1x1km grid enabling the wind speeds experienced at a location to be accurately identified, minimizing basis risk.
Unmatched Scientific Credibility
Backed by hundreds of citations in peer-reviewed publications across a variety of research fields, HWind data is used by researchers and scientists for numerous applications, including numerical weather prediction model validation, and as inputs for storm surge and wave models.
Release of HWind Forecasting Products (2019)
“Powered by a combination of HWind real-time observational data feeds, real-time track forecast data, and the RMS North Atlantic Hurricane modeling framework, our new forecasting products help the market gain earlier insights into potential hazard and loss impacts before landfall, informing key, time-critical decisions as the event unfolds."
Unrivaled Insight and Detail
HWind products reflect wind field characteristics with more frequency, accuracy, and granularity than publicly available sources, including the National Hurricane Center.
HWind datasets incorporate unique wind field analysis metrics developed by HWind scientists, such as Integrated Kinetic Energy, a globally recognized index for measuring tropical cyclone size and intensity, and a proven alternative to the Saffir-Simpson Scale.
Unparalleled Suite of Observational Data Sources
HWind incorporates the most comprehensive set of observational data sources in the market. The mix or private and public data feeds span more than thirty land, air, and sea-based platforms including aircraft reconnaissance, dropsondes, airborne Doppler radar wind measurements, buoys, satellites, and coastal observation networks. HWind also incorporates data from more than 10 types of deterministic and ensemble forecasting models.
HWind Legacy Archive
RMS hosts a publicly-available legacy version of HWind archive data, which contains products from historical events through 2013, developed while HWind was a public entity under the National Oceanic and Atmospheric Administration.

Exposure Management: Managing the Complexity of Estimating...
When a catastrophic event such as a hurricane or an earthquake strikes, an insurance business relies on the exposure management team to answer the big questions: What level of loss is the business looking at, how much will be recovered from our reinsurance, and how do we communicate this? In a recent blog for insurers, I looked at the importance of real-time event response and exposure management; in this blog, I will focus on reinsurance and the need to generate net loss figures. For most reinsurers, answeri...

As Hurricane Ian departed into the Atlantic from Florida’s east coast at 12:00 UTC (08:00 Eastern Time ET) Thursday, September 29, it then regained hurricane intensity later that day at 21:00 UTC (17:00 ET). It has made an unwelcome return; the National Hurricane Center (NHC) has announced that surface observations indicated that the center of Hurricane Ian made landfall on Friday, September 30, as a Category 1 hurricane at 14:05 ET (18:05 UTC) near Georgetown, South Carolina (pop, ~9,000). It had maximu...

The eighth named tropical storm of the current North Atlantic hurricane season, Major Hurricane Ian, made landfall as a Category 4 (Saffir-Simpson Hurricane Windscale) major hurricane near Cayo Costa, Florida at 19:05 UTC (15:05 Eastern Time ET) on Wednesday, September 28. Ian remerged into the southeast Gulf of Mexico after leaving Cuba as a Category 3 storm on Tuesday, September 27, and strengthened owing to warm sea surface temperatures and generally low vertical wind shear. It completed an eyewall replac...
Hurricane Ian: A Potential Category Five Hurricane?
A quiet North Atlantic hurricane season has certainly kicked into life, as Hurricane Ian approaches southwest Florida as a high-end Category 4 (Saffir-Simpson Hurricane Wind Scale – SSHWS) major hurricane. This is the ninth tropical storm of the current season and the fourth hurricane. Comparing this season to 2021, the ninth storm was Hurricane Ida in late August – and it was the most destructive of that year. Ian made landfall near La Coloma on the southwest coast of Cuba yesterday (September 27) as a Categ...
