Two brief EF-0 tornadoes were produced from the same parent circulation as a waterspout came ashore near Rockport, TX. The initial damage as it came on shore was confined to some minor tree damage and a few shingles missing from a couple homes. The tornado then lifted and eventually reformed near FM1781 where it destroyed a couple carports and two sheds. It also snapped some smaller trees and broke numerous large branches before dissipating.

A strong to severe thunderstorm tracked down the Colorado National Monument, across the Redlands, portions of downtown Grand Junction and over the Grand Junction Regional Airport. The GJT ASOS at the Grand Junction Regional Airport recorded 1.07 inches of rain with rainfall rates of 1 inch in 30 minutes and there were several reports of hail/accumulation of hail. Heavy rain resulted in 6 to 8 inches of water running over some downtown Grand Junction streets, in parking lots and topping the curbs. There was standing water along River Road with lots of small hail contributing to drainage issues. Leach Creek near Catalina Drive filled with debris once water reached the HOA, resulting in flooding.

Heavy rain from thunderstorms occurred in the early morning hours of June 21 and caused a major rock slide that damaged part of the railroad track for the Durango to Silverton Narrow Gauge Railroad. Exact time of occurrence is estimated. Part of the 45-mile long railroad track was blocked by a pile of debris after a rock slide occurred. Officials were notified about the rock slide just after 7:30 a.m. MDT that morning. The rock slide happened near mile post 486 just outside Needleton, which is about 55 minutes south of Silverton by train.
San Juan, Colorado · Debris Flow · Jun 21, 10:00 UTC

Significant flooding occurred due to heavy rains from a thunderstorm near Valley of the Gods and northeast of Mexican Hat.

What this means

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.
