ABSTRACT
When users receive a forecast including upper and lower bounds of the predictive interval they may conclude forecast providers acknowledge the forecast’s uncertainty and still consider taking protective action is justified. This is particularly important for extreme events when it is vital for people to trust the forecast and to take the recommended actions (Joslyn, Savelli, & Nadav-Greenberg, 2011). A key determinant of the palatability of warnings to decision makers is whether or not they perceive there are feasible actions they can take at a cost they can afford (Meyer & de Franco, 2011).
