Expect heavy rain and flooding today in North Georgia

One week after a wild stretch of winter weather slammed a large portion of the southern United States with snow, ice and bitterly cold air, some of the same areas are now facing the risk of flooding.

The same storm that brought some of the biggest snowfall accumulations of the winter to parts of Colorado on Wednesday and Thursday is expected to reorganize over the South Central states through the end of the week. This system will be followed by a series of storms that are forecast to move along a developing temperature boundary.

As rainfall develops and lingers along an approximate 1,000-mile-long zone, flooding problems may escalate beyond urban areas to include rapid rises along small streams and high water along some rivers in the region.

Even though the snow and ice that occurred in the south-central region of the U.S. melted and ran off into streams and rivers prior to the arrival of the rain, the soil is still potentially wet enough for accelerating runoff as this rain event unfolds and evolves into a long-duration event.

An average of 1-4 inches of rain is forecast over a several-day period from central Texas to Maryland and Delaware, which would not be enough to trigger widespread small stream and river flooding.

“However, there is the potential for 4-8 inches of rain to occur in localized areas where downpours from multiple storms overlap into next week,” AccuWeather Senior Meteorologist Brett Anderson said.

“An AccuWeather Local StormMax™ of 12 inches is foreseen within that 4- to 8-inch zone, and that big amount is probably most likely to occur over part of the Smoky Mountains in the southern Appalachians,” added AccuWeather Senior Meteorologist John Feerick.

Prior to the start of this rain event, soil conditions ranged from average to abnormally dry to moderate drought west of the Appalachians, according to the U.S. Drought monitor. This means that the soil can handle a reasonable amount of rain over several days, which will be the case in most locations from northeastern Texas to eastern Tennessee and much of Alabama.
