The path drawn at its surveyed width of 200 yards (0.11 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 waterspout moved onshore near the Great Southern Golf Club. Several snapped and uprooted trees were noted in this area and in a wooded area to the northeast of the club. The tornado tracked to the north-northeast, causing damage to several homes along Palmer Dr near Magazine Cir, Oakridge Cir, Hayden Dri, and Lipscomb Ct. A path of downed trees was noted just north of Oakridge Cir. Roof panels were missing from a storage facility building on E Pass Rd. The tornado crossed Debuys Rd and ripped siding off a house on Rainbow Dr. A fence, trees, and large branches were also downed on Rainbow Dr. The tornado lifted shortly thereafter. Survey conducted remotely via high-res aerial photography.

The wider storm

The ninth named storm, fourth hurricane, and second major hurricane of the 2021 Atlantic hurricane season, Ida originated from a tropical wave in the Caribbean Sea on August 23rd. On August 26th, the wave developed into a tropical depression, which organized further and became Tropical Storm Ida later that day, near Grand Cayman. On a northwestward track, Ida intensified into a hurricane on August 27, just before moving over western Cuba. A day later, the hurricane underwent rapid intensification over the Gulf of Mexico as it passed over a warm core eddy and reached major hurricane strength. It was just under 72 hours from tropical depression formation to category 4 strength with 150 mph winds. Ida remained at its peak intensity of 150 mph winds and a minimum central pressure of 929 millibars as it made landfall near Port Fourchon midday on August 29th. It didn't weaken to a tropical storm until it reached near the Louisiana/Mississippi border.

Ida produced over a dozen tornadoes and light to moderate wind damage across southwestern and coastal Mississippi. Around 100,000 residents were without power. Around 100 homes were damaged, 6 destroyed. Storm surge inundation ranged from a few feet in Jackson County to 7 feet in Harrison County. Hurricane Ida caused approximately $10 million worth of damage.

Began near Handsboro (30.3910, -89.0061).
