Extreme weather is the #1 ranked global risk for the decade ahead
The World Economic Forum's 2025 Global Risks Report ranks extreme weather as the most significant global risk for the next decade.
Time is the critical factor. As the interval between extreme weather events shortens, the pressure to implement robust risk mitigation measures intensifies.
With accurate forecasts, real-time monitoring, ground-truth observations, and automated alerts, businesses gain the lead time to protect people and assets, while minimizing operational disruption.

At 16:23, this solar farm will stow the panels to avoid catastrophic hail damage
Severe hail forecasts
Hail damage accounts for over 50% of losses in the solar energy industry, with the average claim at $58 million.
Tracker-mounted panels offer a solution. The hard part is knowing when to stow.
Xweather forecasts hail up to 60 minutes ahead, with at least 20 minutes' warning for 95% of severe hail events. API alert integration triggers automated stow protocols before the storm arrives, removing error-prone manual weather monitoring from the process.

At 20:15pm, the headline act played to nobody
Precipitation protection
Rain is the most common reason outdoor events lose money, yet most organizers only react once it's already raining.
Weather risk data provides high-resolution precipitation data, giving you a clear picture of rainfall probability specific to location and date.
Parametric triggers can be structured around actual rainfall thresholds, based on radar, satellite, and ground-truth observations, to deliver precipitation intelligence with the accuracy and granularity that risk decisions demand.
