Subj : HVYRAIN: Excessive Rainfall Discussion To : wx-storm@lists.illinois.edu From : COD Weather Processor Date : Thu Oct 10 2024 08:27:59 FOUS30 KWBC 100827 QPFERD Excessive Rainfall Discussion NWS Weather Prediction Center College Park MD 427 AM EDT Thu Oct 10 2024 Day 1 Valid 12Z Thu Oct 10 2024 - 12Z Fri Oct 11 2024 ....THERE IS A MARGINAL RISK OF EXCESSIVE RAINFALL OVER PORTIONS OF EAST-CENTRAL TO NORTHEAST FLORIDA... Heavy rainfall from Milton continues to quickly move east across the Florida Peninsula. Additional rain of 1 to 4 inches is likely over the next couple hours along portions of the central and northern FL east coast. However based on recent radar and HRRR=20 trends it appears likely that most, if not all, of this heavier=20 rain will be offshore by 12z this morning. Thus while areas of=20 considerable flash flooding will continue over the next few hours,=20 the expectation is that additional flash flooding after 12z will be minimal. For that reason we will carry only a Marginal risk on the new day 1 ERO that goes into effect at 12z this morning. The=20 ongoing High risk remains valid for the next couple hours until=20 12z. Keep in mind that even after the heavy rain ends, significant areal and river flooding will continue to be a concern in areas=20 that have received significant rainfall. Chenard Day 2 Valid 12Z Fri Oct 11 2024 - 12Z Sat Oct 12 2024 The probability of rainfall exceeding flash flood guidance is less than 5 percent. Chenard Day 3 Valid 12Z Sat Oct 12 2024 - 12Z Sun Oct 13 2024 The probability of rainfall exceeding flash flood guidance is less than 5 percent.
