HIGH Confidence
Your Journey Beta
A brief bumpy patch may occur during cruise. It's nothing to worry about - just keep your seatbelt fastened.
Your route takes you over the Rocky Mountains – conditions there can sometimes cause light turbulence.
Smooth Flight
We're expecting smooth conditions throughout your flight. You can sit back and relax.
Takeoff
Takeoff should feel smooth, with calm conditions around the airport.
Winds Aloft
Winds at cruising altitude are about 72 knots.
Landing
Landing should feel a bit bumpy on descent with typical approach conditions.
You're in Safe Hands
If you feel nervous at any point, remember that turbulence is expected, safe, and part of normal flying. The crew is monitoring everything, and the aircraft is built to handle far more than anything you will feel. Have a safe and calm flight.

☀️ Morning Flight
Morning flights typically experience smoother conditions as the atmosphere is more stable and thermal turbulence hasn't yet developed.
Narrow-Body Aircraft (Medium)
Single-aisle mainline jets like this offer a comfortable ride. While you may feel turbulence more than on wide-body aircraft, they are engineered to handle it smoothly.

Data Sources & Our Approach
ZeroTurb's Custom Algorithm: We've developed a proprietary
ZeroTurb Index (ZTI) algorithm that combines three meteorological indices weighted by their
predictive accuracy. This gives you transparent, passenger-focused turbulence probability instead
of vague categories.
This forecast integrates data from:
- ECMWF Open Data - Global atmospheric model (wind/temperature at 13 flight levels)
- NOAA Aviation Weather Center - Pilot Reports (PIREPs), SIGMETs/AIRMETs, TAFs
- NOAA Space Weather Prediction Center - Aurora forecasts for polar routes
- AviationStack API - Flight schedules and airline operational data
Disclaimer: This forecast is for informational purposes only. Always consult official aviation weather sources and follow ATC guidance.
How accurate are turbulence alerts? Alerts are based on updated forecast models and pilot reports, and can change as departure approaches.
