Subj : HVYRAIN: Excessive Rainfall Discussion To : wx-storm@lists.illinois.edu From : COD Weather Processor Date : Thu Nov 14 2024 07:54:54 FOUS30 KWBC 140754 QPFERD Excessive Rainfall Discussion NWS Weather Prediction Center College Park MD 254 AM EST Thu Nov 14 2024 Day 1 Valid 12Z Thu Nov 14 2024 - 12Z Fri Nov 15 2024 The probability of rainfall exceeding flash flood guidance is less than 5 percent. Maturing surface cyclone off the VA/NC coast will amplify rainfall prospects over the VA Tidewater into Eastern NC late this afternoon and evening with a developing axis of deformation driving elevated convective concerns in the aforementioned areas. Totals between 1.5-3" are forecast within these zones with some minor flooding possible over urban zones and the immediate coast, coinciding with coastal flooding likely occurring. Rainfall rates will fall short of the necessary criteria to meet FFG exceedance, however a non-zero threat will exist for flash flood concerns across Northern NC into Southern and Southeast VA in urban zones that are more prone to flooding prospects. This is still below the 5% threshold necessary for flash flooding leading to a continued nil ERO, but non-zero threat.
