Creation of Rainfall Areal Reduction Factors from the Basin-Averaged Rainfall Record at the Lower Mississippi River Forecast Center
LMRFC Technical Report

 

[PDF]

- A frequency analysis was completed for the gauge-derived, basin-averaged rainfall for subbasins in the LMRFC area. Rainfall amounts from specific average recurrence intervals (ARIs) were compared to values that would be expected to occur for a basin of a given size to look for possible biases in the rainfall database.

 

2016 Preliminary Verification of the Lag-Stage-Changes Routing Technique
LMRFC Technical Report
 

[PDF]

- The Lag-Stage-Changes routing method is a simplified routing scheme used by the LMRFC to aid in forecasting river stages on the Mississippi River between Cairo, IL, and New Orleans, LA. The method is based upon the simplified, hand-calculated forecasting technique used for many years by LMRFC forecasters. Because of increasing demand for long range forecasts on the Mississippi, a verification of the technique was necessary.

Using New Orleans Pumping Data to Reconcile Gauge Observations of Isolated Extreme Rainfall due to Hurricane Isaac
Journal of Hydrologic Engineering

 

[Abstract]

- Slow-moving Hurricane Isaac affected the northern gulf coast between August 28th and August 31st, 2012. This report provides an in-depth examination and analysis of a suspected rainfall extreme in the New Orleans, Louisiana metropolitan area.

Updated Rainfall Analysis for the May 1995 Southeast Louisiana and Southern Mississippi Flooding
LMRFC Technical Report

 

[PDF]

- Very heavy rainfall on 10-11 May 1995 caused significant flooding across portions of southeast Louisiana and southern Mississippi. A post-event technical report, NOAA Technical Memorandum NWS SR-183 (Ricks et al., 1997), provided a meteorological overview and rainfall analysis of the event using rain gauge data. Subsequent changes to the official National Weather Service (NWS) rainfall estimation technique, improved GIS capabilities, and the completion of rainfall frequency estimates for the southern United States have allowed for a new analysis of this event.

 

2014 Analysis of the 15 June 2013 Isolated Extreme Rainfall Event in Springfield, Missouri
Journal of Operational Meteorology
 

[Abstract]

- An isolated extreme rainfall event occurred across portions of the Springfield, Missouri, area on June 15th, 2013, causing substantial flooding of several small headwater tributaries of the James River. A timeline of output from various flash flood nowcasting techniques was compared to the time of reported flooding to evaluate the usefulness of each tool in the context of NWS operations.

Reconciling New Orleans Pumping Data with Gauge Observations of Isolated Extreme Rainfall Due to Hurricane Isaac
LMRFC Technical Report

2012 Southeast Louisiana and Southern Mississippi Flooding Due to Hurricane Isaac
LMRFC Technical Report

 

[PDF] [PPT]

- Slow-moving Hurricane Isaac affected the northern gulf coast between August 28th and August 31st, 2012. The most severe flooding impacts from storm surge and heavy rainfall occurred in southeast Louisiana and southern Mississippi. The slow movement of Isaac was a major contributor to this flooding.

 

 

  LOUZIE: An Operational Quality Control Procedure at the LMRFC
 

[PDF] [Example XLS]

-The Lower Mississippi River Forecast Center (LMRFC) has developed an operational, manual quality control (QC) procedure for gauged precipitation data across the Lower Mississippi River Valley. This report provides a description of the data sources and methodology used to develop the LOUZIE program and spreadsheet along with an example of the monthly spreadsheet from November 2007 in Excel format.

 

 

ENSO Forcing of Streamflow Conditions in the Pearl River Basin - Technical Paper (.pdf)
-Long range forecasts of streamflow conditions can be improved by including the effects of El Nino/Southern Oscillation during operational procedures. This paper uses composite analysis techniques to relate above/below normal streamflows to ENSO episode and tests the skill of forecasts using 1982-2005 data.
ENSO Forcing of Streamflow Conditions in the Pearl River Basin - Powerpoint Presentation
-Presentation provided via Visitview on 7 December 2006 through SRH. [21st Conference on Hydrology (AMS National Conference) in San Antonio, TX in January 2007]

 

Forecasting Hurricane Storm Surge on the Mississippi River - Technical Paper (.pdf)
- A unique forecast problem for the LMRFC is the forecasting of stages on the lower Mississippi River when a hurricane induced storm surge is present. Storm surge waves move rapidly upstream and can cause significant damage and delays to barge traffic along the Mississippi River.

MAP Climatology
- In order to help the forecaster at the WFO with QPF forecasting, the LMRFC has been working on a MAP climatology program. This paper shows some of the statistics for a limited area.

El Nino - Effects on Rivers
- Much has been talked about concerning what effects El Nino is going to have this year. This paper takes a statistical look at how this weather phenomenon will affect the rivers in the LMRFC area.
