Coverage and interpretation

Forecasts cover US land locations supported by the National Weather Service. These tools do not provide global weather or historical observations.

Forecast periods can be hourly or approximately twelve hours. Preserve the returned time zone, units and forecast times when comparing periods.

Alerts are active notices at the requested point. Read each alert’s affected area, severity, validity period and instructions, and follow the official source for updates. A truncated result indicates additional alerts exist.
