Flood Frequency Information
This section of the MARFC website is devoted to flood frequency analysis information for the MARFC forecasting area. It contains information on how many times floods have happened in a specific month, percentages of flood occurrence for each month, probability, and average height above flood stage.
The main function of this project is to give the user historical flood statistics for all of The Middle Atlantic River Forecast Center (MARFC) forecast points. MARFC has received numerous requests from our customers in regards to historical flood information. This project answers these requests for the much needed information.
Flood information is available in an Access database. Please email us if you are interested in receiving a copy.
What's New - 3/10/2015
Richmond, VA and Bremo Bluff, VA 3/7/2015 flood info is being updated.
Reading, PA 2015 flood is bogus and will be deleting it.
Several of the "MARFC Historic Flood Event" tables are being updated for flood stage or moderate/major differences at that time. The tables are a little smaller than usual and some of the font is squeezed in the rows or columns. The different categories will also have minor effects on power rankings which will be updated after we finish the above.
A few low stage readings continue to filter in. We are currently going over this data and will update "Top Five Low Stages" as needed.
We would like to thank The Pennsylvania State University meteorology students for writing up weather summaries for some of our floods in the 1960s and 70s.
All other flood information is up to date. However we noticed a few points in the flood frequency events sections are bogus due to minor, moderate or major category changes. We are currently working on this and will add a message when fixed.
