CRJ-900s have a crosswind limit of ~37 knots sustained (~42 mph) (though I'm seeing different numbers in a few different places, it maybe a little lower) in dry/bare conditions, and can be lower still on slippery runways. Reported winds were ~30 mph sustained with 40 mph gusts. Plausible this was a factor. I will be interested to read the report.
Edit: from an avherald comment:
> Tower ATC alert to Medevac :”Wind 270 Gusting 33”
(Runway 23 is at 230 degrees, so the wind is at 40 degrees relative to the approach.)
> CRJ 900 X Wind Limits:
> • Wet runway: 22 knots for takeoff and landing
> • Fair braking action: 20 knots for takeoff and landing
> • Poor braking action: 15 knots for takeoff and landing
> • High minimums status for PIC: 25 knots for takeoff and landing
> • High minimums status for SIC: 15 knots for takeoff and landing
> Crosswind estimation:
> The maximum crosswind component considers the wind's speed and direction. For example, a 30-degree crosswind has a maximum limit of 50% of the wind speed.
> So here a 40-degree Crosswind, gusting, wet/contaminated Runway with 2” packed snow, 1-2 inches wet snow, Blowing Snow and possible shear all add up to probably exceeding Limits.
