Record number

None yet. SPC numbers 2026 in the spring of 2027.

An EF-1 tornado touched down 1 mile northwest of Brookport along Strawberry Road. It snapped several tree trunks along with producing some damage to the front awning of one house. It continued east crossing Hwy 45 and snapping one more tree along Pell Road before lifting.

Written by NWS PAH in the NWS Damage Assessment Toolkit. A survey is revised as better evidence arrives.

7 damage points were recorded along this path by NWS PAH, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EFU. The highest wind the damage implies is 93 mph.

• Tree trunks were pretty rotted, but a clear circulation pattern noticed.
• This looks to be about the edge of the tornado
• Brief tornado touched down along the TN River.

Survey points are preliminary and are the raw material the published rating was built from. Source: NWS Damage Assessment Toolkit.

13 minutes of warning. NWS PAH issued a tornado warning for this county at 23:01 UTC, 13 minutes before the tornado touched down, in force until 23:30 UTC.

The county was under a severe thunderstorm watch, issued at 17:58 UTC and running to 01:00 UTC.

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 Storm Prediction Center had this point in a Slight Risk, with a 0.02 chance of a tornado within 25 miles. The outlook in force was issued at 20:00 UTC.

SPC's Day 1 convective outlook as it stood when the tornado began, read at the touchdown point. The same archive is on the radar archive.

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 Paducah radar (KPAH), 14 km away, was scanning. The volume nearest the touchdown began at 23:14 UTC.

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. A survey can be revised, so the rating, the path and the casualties can all still change.

NWS Damage Assessment Toolkit, the record the survey teams file from the damage, and NOAA Storm Prediction Center storm reports. Neither is the official database for 2026, which SPC publishes in the spring of 2027.
