Title:

Temporal Distributions of Heavy Rainfall Associated with Updated Precipitation Frequency Estimates

Abstract:

NOAA's National Weather Service has recently updated its precipitation frequency estimates for the semiarid southwest United States and is working on updates for the Ohio River Basin and surrounding states. New estimates for frequencies of 2 through 1000 years and durations of 5 minutes through 10 days are available through a new web portal and will include new estimates of depth-area reduction curves. The update includes estimates of confidence intervals and new probability based temporal distributions that are amenable for use in both traditional deterministic flow modeling as well as probalistic flow modeling.
