The wider storm

A storm with heavy rain of 1 to 2 inches in an hour developed over Pueblo Canyon on the west edge of Los Alamos. Storm runoff from the burnt forest was brief, but intense with water and mud flows estimated at 1500 CFS which overwhelmed the inlet structure west of North Road and then breached the street 60 feet above. A 150 yard section of road surface was destroyed and one of the city's main sewer lines was undercut then broken. Debris fill the basement of at least 5 homes along Alabama Avenue.
