The water equivalent of the snow cover on January 11, 1983
The amounts shown represent the estimated depth of water (mm) that would result from melting of the entire depth of snow present on January 11th, 1983, immediately prior to the rainstorm. Most if not all, of the snow over central and eastern Newfoundland would have been melted by the heavy warm rain of 12-14th, thus adding to the runoff generated by the storm.
