The MARFC's latest Flood Outlook Product data file is now available.
The format of this file is explained
MARFC Significant Flood Outlook graphic is intended to provide a general
outlook for significant river flooding. It is not intended to depict
small-scale events such as localized flooding and/or flash flooding, nor
will it depict coastal and/or tidal flooding. This graphic will not
depict minor river flooding as this implies only minimal or no property
damage with possibly some public inconvenience. Please refer to products
issued by local NWS offices for specific details. For a list of NWS offices

NWS River Forecast Centers use the best available forecasts for future
precipitation given the constraints of current hydrometeorological science.
The number of hours or days into the future that precipitation amounts can
be realistically forecast varies across the United States with seasons and
geographic area. For example, forecast rainfall amounts for hurricanes and
large scale weather systems can extend farther into the future than they can
for local summer thunderstorms.
The MARFC issues 72 hours of forecast precipitation (QPF) throughout the
year. This QPF is used as input to river forecasts as well as MARFC and
National Significant River Flood Outlooks. Therefore, the daily Significant
Maps do not account for a full 5 days of QPF over the MARFC forecast area.
5-Day QPF for the United States can be found at
Prediction Center website. Use the map below to find QPF at other
River Forecast Centers.
