Where the report was made, with tornadoes recorded within 15 miles over the years.

What the National Weather Service wrote

Mescal Canyon low water crossing at Turtleback Ave was flooded and too dangerous to cross. Discharge from the Mescal Canyon caused a 0.65 foot backwater spike on the Rio Grande gauge below Elephant Butte Dam, upstream of Mescal Canyon. Water levels on the Rio Grande came close to riverside porches in Truth or Consequences but no damage.

The wider storm

A deep southeast flow brought plenty of moisture into the region. Storms formed over area mountains and along a mid-level convergence area along the Rio Grande Valley which brought heavy rain and flash flooding to Grant and Sierra counties.

Began near Elephant Butte (33.1509, -107.2147).
