David Drumm's extradition hearing is unlikely to go ahead in Boston today because of snow.
Massachusetts is preparing itself for a powerful storm bringing near hurricane-strength waves and more than a foot of snow.
Courts, schools and city offices have been closed for the next two days.
Lawyers for the former Anglo Irish Bank boss had been expected to tell the court he is no longer fighting his extradition from the United States.
Mr Drumm, who faces 33 criminal charges here, is hoping to be guaranteed bail on his return.
