494 AGUS74 KWCO 031509 HMDNWC National Hydrologic Discussion - EXPERIMENTAL NWS National Water Center - Tuscaloosa AL 1015 AM CDT FRI OCT 3 2025 .Synopsis... Wet pattern through early next week across portions of the Southeast... Heavy rainfall potential across the Southwest late next week... .Southeast... Daily rounds of moderate to locally heavy rainfall through early next week may generate isolated areal and urban flooding impacts along the Southeast Coast (FL/GA/SC) and portions of the Central Gulf Coast (LA/MS/AL). The greatest potential for impacts will be along the east coast of FL, where the heaviest rainfall totals are expected through early next week (3 - 6"+). The latest guidance from the National Water Model (NWM) indicates little to no streamflow response to these areas, supporting the idea of impacts being limited to urban areas. .Southwest... Moderate to potentially heavy rainfall is expected to move into portions of the Desert Southwest (southeastern CA, AZ, and NM) beginning on day 7 (Thursday) as a plume of tropical moisture moves into the region from the Baja Peninsula. Given the extended time range and continued spread in the model guidance, there remains considerable uncertainty in the placement and magnitude of hydrologic impacts. //JDP $$
