Readers should beware that by its nature, the rainfall distribution map (isohyet chart) serves only to indicate visually the spatial pattern of rain. It should not be relied upon to derive exact rainfall amounts at specific locations. Furthermore, this is an automated product generated by computer for quick reference, erroneous data may slip through quality checks in spite of the best of our intentions.
