Will downtown Seattle become windier after the viaduct is removed?

The viaduct provides a low barrier to westerly winds moving off Elliott Bay. That barrier disrupts the flow of westerly winds, leading to slower wind speeds in downtown Seattle, at least that part closest to the Bay. Without the viaduct, that interference won't slow westerlies as much. The lack of a viaduct won't have an impact on winds downtown when the winds are from the north, east or south.
