A storm system that will produce significant snow from the mid-South to the Appalachians will also bring the risk for flooding rains from the Southeast into the Middle Atlantic. Flash Flood Watches have been issued from Georgia northward to Chesapeake Bay. Up to 4″ of rain may fall by Friday in the watch areas.
The storm system will start in the Gulf of Mexico, pulling up significant humidity. The extra moisture in the atmosphere will be brought northward by the low Thursday into Friday. This will aid in the risk for heavy rain and flooding. Poor drainage areas near creeks, streams, and ditches will be most susceptible to flooding. Street flooding is also possible. The ground remains saturated due to rainfall accumulation over the last few weeks. As a result, it will not take much rain to produce flooding issues.
