ABRFC River StatusWARNING: RAW MODEL OUTPUT -- Please read and understand the following disclaimer on the use of this information.
Important Disclaimer: This service provides RAW MODEL, SHORT-TERM ENSEMBLE guidance from the latest run of the ABRFC river forecast system. These data are NOT to be construed as official forecast products, because ABRFC official forecast products may differ significantly from the raw model output due to many reasons. Raw model output always requires forecaster review, and often requires significant modification before release as an official river forecast product.
The raw model guidance provided here is based on three types of forecast precipitation (QPF) input of varying durations. These are the official WPC forecaster-produced (deterministic) QPF, and WPC's algorithmically-produced maximum and minimum QPF at the 95% confidence interval. Maximum or minimum QPF at the 95% confidence interval means that there is only a 5% chance of the actual rainfall exceeding or falling short of that QPF value, respectively, in each six-hour period. The runoff resulting from the maximum or minimum scenario has a 5% or lower probability of being exceeded or not being reached, respectively.
The summary map on this page gives a quick look at the flood status for each river basin based on all ensemble members. Detailed hydrographs of each ensemble member and its associated precipitation input can be accessed from the regional pages by clicking on the map below.
These data are provided primarily for coordination purposes - to give a fast "heads up" of potential flood problem areas immediately after a forecast model run, coordinate QPF, etc.
