From the Storm Events narratives, unedited.

Torrential rainfall, as much as 5.48 inches of rain having fallen in 90 minutes in Rancho Viejo, left pockets of flash flooding during the late afternoon between San Pedro and Olmito, including Rancho Viejo. Reports of high water into structures and vehicle rescues were reported during and after the peak of the downpour. Vehicle rescues were reported in Olmito and near Rancho Viejo; water was reportedly entering homes on Melva Court in San Pedro, and Burr Oak Loop and Agave avenue just south of IH-169 in east Olmito. Damage values estimated based on the reports received. Damage information was unknown at the time of this writing.

Cameron, Texas · Flash Flood · Sep 15, 22:00 UTC

Torrential rain, with measured an estimated totals of 3.5 to more than 5 inches mainly from downtown across the north and west portions of Brownsville, created numerous instances of flooding and flash flooding. Standing water was reported on the intersection of Pablo Kisel Blvd and Morrison Road. Roadway was nearly impassable. Additional reports from Cameron Co. and Brownsville Emergency Management included: water covering roads at IH-69E Frontage and Alton Gloor, Old Alice/Barnard/Price. A water rescue was reported downtown on 11th and Elizabeth. Water levels in harder hit areas were between 2 and 3 feet (standing). Damage estimates were unknown as of this writing.

Heavy Rainfall just east, northeast of Towaoc resulted in debris flows across Highline ditch/canal. Debris flow with mud and large boulders were noted near mile marker 29 on Highway 491 (between 21 Rd and B Rd).

Montezuma, Colorado · Debris Flow · Sep 16, 21:00 UTC

A severe thunderstorm moved through 8 miles west of Ignacio and tracked to the northeast at 30 mph. Path and time was estimated based on the Severe Thunderstorm Warning issued. Thunderstorm wind damage occurred with downed trees, a bent electric pole and a twisted power pole. Property damage occurred in which an RV camper was smashed in half from the downed trees. Uncertain if this was tornado or straight line wind/downburst damage but leaning downburst winds.

La Plata, Colorado · Thunderstorm Wind · Sep 17, 00:30 UTC

The county Emergency Manager and Quay County Sun newspaper reported 10 commercial vehicles were blown over on I-40 due to severe thunderstorm wind gusts. This along with 7 other simultaneous crashes closed I-40 for several hours in both directions. Several people were taken to the local hospital in Tucumcari as emergency response from Logan, San Jon, Tucumcari and the Quay Fire District 2 responded to the incident.

Quay, New Mexico · Thunderstorm Wind · Sep 17, 21:15 UTC

Severe thunderstorm wind gusts blew of a community center roof, church doors and destroyed numerous outbuildings in Nara Visa as reported in Quay County Sun.

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.
