Hurricane Ida made landfall on the coast of Louisiana Sunday as a powerful Category 4 hurricane, but was downgraded to a tropical storm early Monday. It's the storm's slow movement, sustained power and direction that are of ongoing concern.
Ida has slowed considerably but continues to draw energy from its own storm surge as well as the moisture of the area. The combination is hitting New Orleans with heavy rains in addition to strong winds, overpowering some levees and leaving more than one million people without power throughout Louisiana.
