Heavy snow and ice accumulations are likely to produce hazardous travel, downed trees, and power outages. Heaviest snow is expected along and just west of the Appalachians, and the most damaging icing is likely across parts of North Carolina. Thunderstorms may produce damaging winds and tornadoes in Florida and the eastern Carolinas. Strong winds and coastal flooding are also expected. Read More >
Snow and ice accumulation does not impact river conditions right away, but is instead stored at the soil's surface. During warmer periods, snow cover melts, which may cause river rises similar to that caused by rainfall. Snow cover is modeled to help improve river forecasts.
