Severe Weather Alerts and Safety Guidance
The app emphasizes life-saving information, with tiered alerts based on severity and proximity. You can customize which types of warnings reach your device and how they are delivered.
How Alerts Are Prioritized
Warnings appear with loud sounds and prominent banners, while watches and advisories show as quieter notifications. Safety tips are included so you know the recommended actions before, during, and after an event.
Interactive Radar and Detailed Forecasts
High-resolution radar imagery and satellite loops help you track storms in near real time. Hourly and extended forecasts provide temperature, precipitation probability, wind, and humidity details for better planning.
Customizable Map Layers
You can add layers for rainfall, snow, lightning, temperature, and wind speed. These options make it easier to understand evolving conditions across your area and nearby travel routes.
Location Accuracy and Privacy Settings
The app uses GPS, Wi‑Fi, and cellular signals to pinpoint your location while offering control over what data is shared. Clear permissions let you decide how location history is handled.
User Control Over Data
You can manage which sensors and services the app accesses, revoke permissions at any time, and review the privacy policy for details on how information is stored and used.
Reliable Performance Across Devices
Engineered for stability, the app delivers consistent updates even during high-traffic events. Adaptive refresh schedules help balance accuracy with battery life on smartphones, tablets, and wearables.
Optimizing Battery and Data
Background refresh is tuned to minimize impact, and you can choose lower frequency updates when network conservation is important without sacrificing critical alerts.
