Weather disclaimer
LeadTime is not an official warning service. It relays National Weather Service warnings and adds radar-based predictions, but it depends on a network connection and on data that can be delayed or wrong.
- Radar-based arrival times are estimates. Storms change direction, speed and strength, and small showers can appear where there was nothing minutes before.
- Lightning can strike well outside the rain; "no rain heading your way" does not mean "no lightning risk".
- Alerts can be delayed or missed if your device is offline, in power-saving mode, or has notifications disabled.
- For life-safety decisions, use official sources: NOAA Weather Radio, Wireless Emergency Alerts on your phone, and local authorities.
