Safely Air pressure at Tromso down to 945 mb, and wideroe and other airlines can’t set the kollsman window that low so grounded. Not sure it is the lowest, off the west coast and up north experiencing floods and record low pressure. The news reported they can’t “land” when the altimeter is not set correctly, but you really don’t use altimeter for final, etc, so, is it just the approach descent that would be dangerous? Flight level should still work as all set to the same setting so...?? Anyway, no flights.
