Severe weather on two different fronts is threatening travel on two different coasts.

And no, it’s not the usual suspect – the northeast, where temperatures were in the 50s this weekend and expected to stay there into next week.

This time, devastating storms and tornadoes have hit the southeast, and Winter Storm Leo is expected to pound California with snow in higher elevations as it moves east into the Midwest.

The situation at the moment has been more dire in the southeast, where the New York Times is reporting that 15 people have been killed and 43 injured in Georgia and Mississippi by violent storms, many of which spawned tornadoes.

According to The Weather Channel, the National Weather Service has issued a PDS Tornado Watch – Particularly Dangerous Situation – for parts of Georgia, north Florida and southeast Alabama into Sunday evening. Outside that high risk area, high winds, hail and the formation of tornadoes could impact other parts of Georgia, Florida, Alabama and the Carolinas.

So far on Sunday however, most airline delays and cancellations have been further north at Detroit and New York, mostly due to morning fog.

Out west, The Weather Channel noted that rain will continue in California, becoming heavy in southern California, which could trigger flash flooding and mudslides. Southern California rainfall in the higher elevations below snow level could total three to six inches, while coastal and valley areas may see two to four inches of rain.

Heavy snow will continue to pound the Sierra Nevadas, and accumulating snow is also likely in the Reno, Nevada, area, potentially making travel impossible in some areas.

The storm is expected to continue and easterly track into the Midwest.
