Alternate minimums are planning minimums, used to determine fuel load for dispatch. Once en route you can plan to land at destination, filed alternate or any other suitable field, as long as the approach you intend to fly remains at or above published minimums. If the Wx at your filed alternate deteriorates below the planning minimums while en route there is no regulatory requirement to chose another alternate, though obviously it would make good sense to do so.
