DISCUSSION: The above figure shows snowfall totals over the past 24 hours from the National Operational Hydrologic Remote Sensing Center (NOHRSC) showing measureable snowfall in areas that don't regularly see snow (e.g., New Orleans, Brownsville, TX, southern Mississippi). Because these areas don't see snow often, they generally are not as prepared for snow as more northern locations. For example, many cities in the south don't have snow plows or salt trucks. Thus, even a little snow can make travel treacherous. But, some of these areas received more than 8 inches of snow over the past 24 hours (i.e., southern Mississippi), according to the above graphic. It is best to avoid driving in these conditions if you can help it. But, if you must go out, be sure to drive slowly and avoid making any sudden changes in speed or direction. In other words, drive extremely carefully. The storm system responsible for this snowfall is also causing issue with air travel. For example, Delta has canceled 600 flights in Atlanta as described here. This winter storm is expected to move up the eastern seaboard. Hence, people in the northeast U.S. who are better prepared to handle winter weather should nevertheless prepare for the upcoming impacts of this storm.
