8. Which of the following ways to present gridded eTRaP forecasts of heavy rain would
be more beneficial to the operational forecaster?
Give the probability of exceeding a certain rainfall accumulation for each specific 8km grid box. This approach would be more precise as far as the location of the highest
probability of heavy rainfall, but the probability values will never be all that high because
it's so difficult to predict the exact location of heavy rainfall.
Give the probability of exceeding a certain rainfall accumulation somewhere within,
say, 40 km of the grid box of interest. This approach would be less precise as far as
location, but would give a better picture of the overall risk of heavy rainfall in a general
area.
9. I have the following additional comments: __________________________________
