Maricopa, Arizona · Flash Flood · Jun 16, 22:00 UTC

Thunderstorms with very heavy rain developed just north of Carefree and Cave Creek during the middle of the afternoon on June 16th. Radar indicated that rainfall amounts of up to 2 inches fell in the area, and this led to flash flooding. According to a member of broadcast media, at 1630MST water was flowing swiftly across north Echo Canyon Road, immediately south of the intersection with north Fleming Springs Road. At 1526MST a Flash Flood Warning was issued for the area and it remained in effect until nearly 1800MST.

Maricopa, Arizona · Flash Flood · Jun 16, 22:00 UTC

Rock and other debris flowed just south of the Iron Horse Inn along and onto Highway 550 as a result of heavy rainfall. CoCoRaHS observers reported 0.70 inches of rain fell with storms near that area.

La Plata, Colorado · Debris Flow · Jun 17, 11:30 UTC

Heavy rainfall caused a mud to flow across the westbound lane of Interstate 70 at the Avon Exit 167. That portion of I-70 was closed for about 50 minutes until the debris was removed. Radar estimated storm total rainfall was up to 0.50 of an inch in less than an hour.

A best track is the record a warning agency settles on after the storm, not what it said at the time: position, maximum sustained wind and central pressure every six hours, revised against every observation that came in later. Category is the Saffir-Simpson scale, which runs from Category 1 at 64 kt to Category 5 at 137 kt and reads wind only, so it says nothing about surge or rain. Accumulated cyclone energy adds up the square of the wind through the storm's life, so it counts strength and duration together.
