Precip.net: Extreme Precipitation in New York and New England

Researchers can use this resource to assess extreme rainfall return frequency for New York and New England, using an alternate methodology to that used in NOAA Atlas 14.

This website offers estimates of extreme rainfall for various durations (from 5 minutes to 10 days) and recurrence intervals (1 year to 500 years) for New York and New England. These data are interpolated to a 30-second grid. Confidence intervals for these values are also included, as are the partial duration rainfall series used in their computation. Regional extreme rainfall maps and graphic products are also available.
