Forecasting - Cal State LA

To a forecaster, a good hurricane forecast is getting the location right
within 50 miles and the wind speeds within 8 mph in the period 12

accuracy 72 hours ahead of time. That gap is the reality that underlies
decision making.
Why is it that forecasts are imperfect, and how do forecasters and
emergency managers take that uncertainty into account? By choosing
