After reviewing several additional photos of the June 5th, 2024 EF1 tornado in Eldersburg, Maryland, I reached out to NWS Sterling to determine whether the images might support an upgrade to EF2. Following a week of analysis, they officially upgraded the tornado to EF2 with 120 mph winds.

Wow, looks like there was a tornado in Juneau, Alaska on June 16th. This appears to be a landspout tornado that occurred as a severe thunderstorm passed through the area. Incredible!

Some impressive afternoon thunderstorms moved through eastern New Port Richey, Florida earlier today. The storms produced strong downbursts and made a few weak attempts at tornadogenesis, but all were disrupted by outflow-dominant conditions.

Yesterday’s highly photogenic, deviant tornado near Dickens, Nebraska has been rated a high-end EF2, with estimated peak winds near 135 mph. Numerous trees near the end of its path were denuded and debarked, resulting in a high-end EF2 rating.

Preliminary intensity guidance for the tornado that struck SE of Columbia, Mississippi (Mar. 31, 2025):
The tool indicates low-end EF3 (140 mph), with a possible range of 130-150 mph (EF2/EF3), pending NWS damage surveys.
This is an estimation, not an official rating.

I suggest using DoD-5 [Trees debarked with only stubs of large branches remaining] with the "EXP" classification. This adjustment would yield a low-end EF3 rating (145 mph) for the tree damage.

The tornado also flattened a 1,200-ft-wide swath of trees along the Stillwater River. Many were denuded and debarked, but these trees are not particularly strong. NWS classified this area under DI-27 (Hardwood Trees)

Based on my analysis, neither DoD-5 nor DoD-6 matches the observed damage. Instead, DoD-4 [Uplift or collapse of roof structure, leaving most walls standing] is more appropriate. Considering the apartments were well-constructed, the "EXP" designation applies. This results in—

Most buildings at Rivers Edge Apartments lost their roofs, with some exterior walls on the top stories collapsing. The NWS applied DI-5 (Apartments, Condos, Townhouses) with DoDs 5 and 6:
DoD-5: Most top-story walls collapsed (EF3/160 mph)
DoD-6: Almost total destruction—

On May 27, 2019, a low-end EF4 tornado tore through Montgomery County, Ohio, including the Rivers Edge Apartments. However, I believe the damage in this area was overrated based on the misuse of Damage Indicators (DIs) and Degrees of Damage (DoDs).

This unexpected, but intense tornado completely destroyed a large farmstead. Among the destroyed structures, was a well-constructed MBS (Metal Building System), swept clean from its foundation. Revised EF scale suggests low-end EF4:

As of now, the year 2024 has four recorded EF4 tornadoes. Those being:
1. Elkhorn, NE - Modale, IA | 4/26
2. Marietta, OK | 4/27
3. Barnsdall, OK | 5/6
4. Greenfield, IA | 5/21
Though, there are a few more I personally think should've earned a violent rating, here's why.
