SHOWERS AND THUNDERSTORMS WILL INCREASE ACROSS FROM THE SOUTH SATURDAY NIGHT AS DEEP MOISTURE SURGES NORTHWARD FROM A STALLED FRONT NEAR THE COAST. LOW PRESSURE WILL FORM ALONG THE FRONT ON SUNDAY AND MOVE JUST NORTHWEST OF THE NATCHEZ TRACE WHILE DEEPENING SIGNIFICANTLY. DEEP AND IMPRESSIVE LIFT WILL CREATE A VERY EFFICIENT ENVIRONMENT FOR HEAVY RAINFALL ON SUNDAY AND SUNDAY NIGHT ACROSS SOUTH MISSISSIPPI. SOILS ARE VERY WET DUE TO THE RECENT RAINFALL AND MANY RIVERS ARE ELEVATED WITH A FEW FORECASTS POINTS ABOVE FLOOD STAGE. RAINFALL WILL RANGE FROM 2 TO 4 INCHES WITH LOCALLY HEAVIER AMOUNTS POSSIBLE. THIS EVENT COULD PRODUCE SIGNIFICANT FLASH FLOODING AND MINOR TO MODERATE RIVER FLOODING. THE MOST SIGNIFICANT POTENTIAL FOR FLOODING WILL BE IN SOUTHEAST MISSISSIPPI WHERE THE HEAVIEST RAINFALL IS CURRENTLY EXPECTED. THOSE ALONG THE LEAF RIVER...TALLAHALA CREEK...BLACK CREEK...BOUIE CREEK IN SOUTHEAST MISSISSIPPI NEED TO BE PREPARED TO TAKE ACTION IN CASE LOCALLY HEAVY RAINFALL OCCURS. THE PEARL RIVER AND TRIBUTARIES IN CENTRAL AND SOUTH MISSISSIPPI ARE RUNNING HIGH AND THE ADDITIONAL RAINFALL COULD PRODUCE MINOR TO MODERATE FLOODING. THE BIG BLACK... CHUNKY... CHICKASAWHAY...AND NOXUBEE RIVERS AS WELL AS TIBBEE AND LUXAPALLILA CREEKS IN CLAY AND LOWNDES COUNTIES COULD ALSO SEE MINOR TO MODERATE FLOODING. THOSE ALONG MAGBEE CREEK IN COLUMBUS MISSISSIPPI NEED TO STAY INFORMED OF THE LATEST FLASH FLOOD INFORMATION. THIS WEATHER SYSTEM HAS PLENTY OF MOISTURE TO WORK WITH. THERE IS STILL SOME UNCERTAINTY ASSOCIATED WITH THE PREDICTED RAINFALL AMOUNTS AND THE LOCATION OF HEAVIEST RAINFALL. THOSE LIVING IN FLASH FLOOD PRONE AREAS AND AREAS AFFECTED BY RIVER FLOODING NEED TO KEEP ABREAST OF THIS POTENTIAL FLOOD RISK.
