Missouri residents struggled through a fourth straight day of storms on Tuesday, fighting rising floodwaters that inundated homes, forced evacuations and closed highways and even part of the Mississippi River.

A week of chaotic weather continued throughout the United States as a storm system that spawned deadly tornadoes in the Midwest and Southwest pushed north. More than 40 people have died of weather-related causes during the Christmas holidays in the past week.

Missouri has been pounded by downpours since Saturday, and forecasters warned that its major rivers were still days away from cresting at record levels.
