An active stretch of severe weather across eastern New Mexico continued on May 17, 2021 with a significant severe weather outbreak that included multiple tornadoes. As a potent low pressure system approached the state, instability and shear increased across the area, providing a favorable environment for severe thunderstorms. Convective initiation started by late Monday morning over the high terrain of New Mexico. Steering flow generally moved the storms in a northeasterly direction where they intensified over the plains. Several reports of hail and severe winds were received as well as multiple tornado reports. Two supercell tornadoes occurred across eastern New Mexico, but no damage occurred. The environment was even favorable for tornadoes in central New Mexico where three landspout tornadoes were confirmed.

A member of the public reported a landspout tornado near Abo, but no damage was reported.

From NOAA NCEI's Storm Events Database, the narrative the local forecast office wrote for Storm Data.

No tornado warning for this county appears in the archive as in force at the moment the tornado touched down.

Every warning and watch covering the touchdown point that day, from the Iowa Environmental Mesonet's archive of National Weather Service products. Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.

The radiosonde launches on either side of the tornado, from the nearest station that was launching then, drawn and analyzed the way Storm Lab does: the same diagram, the same parcel and shear definitions SPC's mesoanalysis uses.

The Albuquerque radar (KABX), 96 km away, was scanning. The volume nearest the touchdown began at 17:42 UTC.

16 more were confirmed in the United States that day.

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
