EF1 tornado in Montgomery County, Arkansas

A tornado exited Clark County west-northwest of Elm and entered Montgomery County east-southeast of Welsh. In Montgomery County, the tornado knocked down trees, power lines, and power poles, took the roof off of a barn, and caused a tree to fall on a house. The tornado exited Montgomery County east-northeast of Welsh and entered Hot Spring County west-southwest of Bonnerdale.

From the 24th through the 27th, the arrival of a slow-moving cold front and several low pressure areas aloft triggered several rounds of thunderstorms. Tornadoes, severe storms, and flash flooding resulted. Widespread areal flooding followed the flash flooding. Some of this flooding was due to heavy rain, while some of it was caused by water from rivers, creeks, and bayous backing up onto the land. On the evening of the 25th, devastating tornadoes affected several areas in central Arkansas. More than 140,000 electric customers in Arkansas lost power. Heavy rains during this period were the beginning of the Great Flood of 2011 in Arkansas. Much of the flooding lasted well into May, and some even continued all the way to late June.
