Subj : HVYRAIN: Excessive Rainfall Discussion To : wx-storm@lists.illinois.edu From : COD Weather Processor Date : Sun Mar 09 2025 08:36:09 FOUS30 KWBC 090835 QPFERD Excessive Rainfall Discussion NWS Weather Prediction Center College Park MD 435 AM EDT Sun Mar 9 2025 Day 1 Valid 12Z Sun Mar 09 2025 - 12Z Mon Mar 10 2025 ....THERE IS A SLIGHT RISK OF EXCESSIVE RAINFALL OVER PORTIONS OF THE SOUTHEAST UNITED STATES... Have introduced a Slight Risk area from the Florida panhandle eastward into portions of the northern Florida peninsula and adjacent portions of southern Georgia given increasing support=20 from the models...both global and mesoscale...for higher rainfall=20 amounts/rates. Present indications are that convection capable of producing rainfall rates in excess of an inch per hour will be possible in a corridor along/near the coastal portions of the Florida panhandle northeastward from this morning into early afternoon (approximately in the period from 12Z to 18Z) in association with one shortwave=20 that taps some Gulf instability. Another round of moderate to heavy rainfall looks to develop in the 10/00Z to 10/06Z period as a=20 second shortwave follows a similar path as the first shortwave. Rainfall totals in of 2 to 4 inches could occur within that=20 corridor...although there could easily be some higher amounts=20 embedded within the belt of heavy rainfall. Those rainfall amounts=20 have the potential to result in flooding of low-lying areas, creeks and roadways.
