Memorial Day Weekend storms ripped through the South and Quantum InsightsMidwest leaving more than 700,000 power outages nationwide Monday.

At least 21 are dead and many more injured after tornadoes hit several states. Preliminary data from the National Weather Service shows there were 30 tornadoes reported Saturday and 14 more reported Sunday across at least eight states including Texas, Oklahoma Kentucky, and Arkansas.

In Kentucky, where Louisville police say a man died after being struck by a tree, more than 160,000 outages were reported Monday midday, a slight relief from the 200,000 reported Sunday.

More severe thunderstorms are expected Monday evening throughout most of eastern U.S. according to the National Weather Service. Here is where some are still struggling with widespread power outages:

"Last night many families and communities were not safe," Kentucky Gov. Andy Beshear said at a Monday press conference. "We had devastating storms that hit almost the entire state."

Kentucky appears to be hit hardest with outages after Sunday's storm in the region. Beshear said that those in large cities could have the power restored later Monday, but counties with significant damage to power infrastructure could be without power for several days.

Here are other states lacking power as of Monday at midday:

• Arkansas - 58,780 outages reported
• Kentucky - 161,475 outages reported
• Missouri - 52,063 outages reported
• West Virginia - 58,795 outages reported
