Unrated
The survey recorded a tornado but could not put a number on it, most often because it crossed open country and damaged nothing a rating can be read from.

What the Weather Service recorded
On May 2, 2024, a significant weather event unfolded as a waterspout |made landfall, impacting the Cambalache sector within the |Municipality of Arecibo. The inclement weather in this region was |spurred by a mid to upper-level trough shifting from west to east |along Puerto Rico's northern coast. Doppler radar scans revealed |several velocity couplets at an altitude of 6000 feet, indicating |the potential for turbulent weather conditions. As the |waterspout transitioned into a weak tornado, it encountered an |expanse of mangrove trees, resulting in the downing of numerous |small to medium-sized branches along its path. Additionally, the |tornado's winds affected street signs and canopy tents, which were |blown away by the force of the storm.

As the |waterspout transitioned into a weak tornado, it encountered an |expanse of mangrove trees, resulting in the downing of numerous |small to medium-sized branches along its path. Additionally, the |tornado's winds affected street signs and canopy tents, which were |blown away by the force of the storm.

What this means
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.
