The storm precipitation in a mountainous watershed in the southwestern British Columbia has been studied. Analysis of the spatial distribution of the storm features showed that the precipitation always increases up to the mid-position of the watershed, and then may decrease and/or level off or increase again, depending on the type of the event. Examination of the time distribution of the storms indicates that the precipitation is, on average, equally distributed over the duration. These results, along with the finding of the study that the antecedent precipitation is large, can result in better estimation of the runoff from the mountains of the area.
