What is a PIREP and why is it important to ATC?

A PIREP is a Pilot Weather Report, a real-time in-flight observation from a pilot about the weather encountered at the aircraft’s current location and altitude. It describes actual conditions such as turbulence, icing, cloud tops, visibility, and winds aloft as observed by the crew. This live information is valuable to ATC because it provides current hazard data that you might not see from ground-based tools or forecasts. Controllers can use PIREPs to issue turbulence advisories, adjust routes or altitudes to avoid rough air, and keep other flights informed about evolving conditions. They also help meteorologists refine forecasts and warnings for the area. PIREPs are observations, not forecasts or maintenance data, and they capture real conditions pilots are experiencing rather than predicted ones.
