Some 250 tornadoes wreaked havoc in the US last week, and—brace yourself—another possible wave of tornadoes may hit this week. Last week’s tornadoes killed at least 47 people across six states; now, a storm system heading east from the Rockies is threatening new snow, flooding, hail, and more tornadoes, AOL News reports. The area stretching from the Ohio Valley toward Texas faces the greatest danger from tomorrow into Wednesday.
Starting today, the Plains and Missouri Valley could be hit with powerful thunderstorms. Nearly 18 inches of snow, meanwhile, is expected in Montana’s mountains. Rivers and streams from the Plains to the Northeast are already near flooding; the Ohio Valley and Midwest will likely receive the most rainfall. The storm system is poised to be the fourth this month to prompt tornadoes and risky thunderstorms. There have been 371 preliminary tornado reports in the US so far in April, versus a 3-year average of 185 at this point.
