What about windspeed?

Pedantic maybe, but 140KTAS or 140KCAS. If the pitots only observe the normal component they may only report an "unbelievable" 70KIAS. With wind and sidelip it is easy to see the IAS from any/all unfrozen sensors moving across the 30-60kt range and responsible for initiating/blanking alarms.

Pitot tubes are designed to have little effect over +/-20 degree range, higher than this is possible with 'shroud' extensions
