How StormAuditor Measures Severe Weather
StormAuditor uses the SAWE-2 (Storm Auditor Wind Estimate, engine v2.12) and SAHE-2 (Storm Auditor Hail Estimate v2) methodologies to estimate wind and hail sizes. These estimates are based on radar-derived data and ground reports.
Practical Guidance
For those researching date of loss in Maryland, it's crucial to understand the process. StormAuditor's /address-lookup tool provides property-level historical weather reports, including wind and hail data. The /date-of-loss-weather-research workflow guides users through the research process. Additionally, the /weather-on-this-date tool allows users to search for weather events by date.
