Weekly Extreme Precipitation Probability


Product Overview


Probabilities of meeting or exceeding precipitation amounts associated with different recurrence intervals (1-yr, 2-yr, 5-yr, 10-yr, 25-yr, 50-yr, 100-yr) and accumulation periods (24-hr, 18-hr, 12-hr, 6-hr, 3-hr, 2-hr, 1-hr) during each week of the year were computed for 7 regions across New York. Each region is composed of individual stations that are geographically juxtaposed and observe similar timing of extreme precipitation events throughout the annual cycle.  The values on each graph provide the exceedence probabilities for a given week and recurrence interval, based on the user-specified accumulation period and region of interest.
