The path drawn at its surveyed width of 15 yards (0.01 mi) — zoom in and the swath grows to true scale. Other tornadoes recorded nearby that day are shown faint.

What EF0 means. On the Enhanced Fujita scale, EF0 is light damage: shingles and siding peeled, gutters torn, branches broken, consistent with estimated gusts of 65–85 mph. The rating comes from a survey of the worst damage after the storm, not from a wind measurement, so it says as much about what the tornado hit as about how strong it was.

What the National Weather Service wrote

A weak tornado developed near Highway 2 in Aguadilla early

in the afternoon of Wednesday, August 9, 2023. The brief tornado primarily

impacted a structure, tearing off aluminum roofs from a garage and causing

damage to vehicles in the affected area. Additionally, associated

with this severe thunderstorm, strong gusty winds from the outflow

affected the area near Crash Boat Beach, resulting in trees falling onto

parked cars and fallen power lines.

The wider storm

The combination of abundant tropical moisture from a departing tropical wave interacting with an upper-level trough north of the region produced strong afternoon thunderstorms over northwestern Puerto Rico on the 9th of August. A weak EF-0 tornado and strong outflow boundaries caused thunderstorm wind damage across the municipality of Aguadilla.

Began near Aguadilla (18.4513, -67.0931).
