WeatherFlow has a professional network of stations installed along the coastal US specifically to measure oncoming hurricanes. These stations are $100k+, installed in key locations, professionally sited and installed, and built to survive and continue to collect data during hurricane events. Our “hurricane network” is used by the National Hurricane Center as well as all regional NWS offices impacted. During tropical storm activity, WeatherFlow opens access to a suite of professional forecast and observation tools via our DataScope product.
See http://ds.weatherflow.com/storm/florence#32.881,-74.35,5,8 for exclusive Florence coverage including live data from hurricane hardened stations along the Carolina coast.
As a reminder, the WeatherFlow auto-calibration / applied machine learning system has not yet been deployed for rain accumulation across the network of home Smart Weather Stations. Expect some odd accumulations totals until we deploy the full system.
