Lukeville, the town this property stands in, in 10 storm reports between 1998 and 2025: 5 flash flood, 4 thunderstorm wind, 1 flood.
No death or injury is recorded in these reports. Each account below is quoted exactly as the forecast office
filed it, from the NOAA Storm Events Database, and each date
opens the federal record of that event.
Two to three inches of rainfall occurred in the border town of Lukeville, Arizona. This caused flooding and damage to private property, businesses and government offices with water several feet high. A report from officials at Organ Pipe Cactus National Monument stated a recently built fence along the international border exacerbated the flooding as a result of the fence acting like a dam and stopping the normal progression of water through the border.
Rainfall amounts between 1.5 inches and 2.5 inches resulted flooding and the closure of several roads at Organ Pipe National Monument. In addition, a 40 foot section of the international border fence between the United States and Mexico was destroyed.
Heavy rain caused normally dry washes to flow with water. Stream gages reported rises up to 5 feet. Some road closures were reported especially in the eastern and northern portions of the Tucson Metro area.
