Harveyville KS tornado article in Wichita Eagle misses some facts

An article here by Stan Finger in the Wichita Eagle yesterday about the recent Harveyville KS tornado (see my previous blog post last Thursday 3/1/12) claiming that there was "no warning" was not totally factual. There was indeed a severe thunderstorm warning issued that mentioned a tornado watch was in effect, as well as the possibility of tornadoes that could form quickly (see above). In my opinion, the way the article was edited (after talking by phone, I found out that the "no warning" headline was not Mr. Finger's responsibility) put the focus on the wrong issues, and was NOT helpful in improving public weather safety response and perceptions.

To be clear, the Harveyville tornado was light years away from the Joplin tornado in its brevity and weaker intensity, and it is ridiculous to focus on that isolated event compared to all the other tornadoes that occurred on Feb 29th and March 2nd when the National Weather Service did an exemplary job regarding watches, warnings, and public awareness. The article also came off, courtesy of quotes by Mike Smith, as a free advertisement for Accuweather's "superiorty" in detection and warning. In serving utility clients like Westar Energy, this corporate for-profit entity has none of the public responsibility and pressure that the National Weather Service has in an era where the general public wants to be warned about everything that affects them directly (an impossibility, even with our technology), but also thinks there are too many false alarms.

Here is an e-mail letter I sent to Stan Finger this morning:

Your article yesterday about the Harveyville KS tornado was disappointing, and really missed some facts.

First, there _was_ indeed a warning in effect for Harveyville when the tornado hit... a severe thunderstorm warning that specifically mentioned Harveyville and the possibility of strong winds (see attached). It also mentioned that a tornado watch was in effect and that tornadoes can develop quickly from severe thundertorms. So, your headline "Harveyville tornado struck without warning" is misleading and incorrect.

The brief and narrow Harveyville tornado lasted only 4 minutes and happened to go right down through town. Had it occurred a couple miles north or south of where it did, we might not have even heard about it. The small tight rotational signal that appeared on radar was truly visible for only one scan as it was upon Harveyville, with no time for an advance specific tornado warning.

The quotes you gave from Mike Smith were not at all in proper context, and were like comparing walnuts with oranges when talking about what Accuweather does relative to the National Weather Service. "Warnings" given by Accuweather are mainly for utility and transportation clients, who don't generally object to overwarning issues... they just want to be prepared and alert for power line breaks and transportation interruptions in specific locations, whether from strong straight-line winds or tornadoes.

So, Accuweather can issue tornado warnings continuously and indiscriminately along a long-track supercell's 3-4 hour path without public complaints and repercussions, regardless of whether verified damage is from winds or tornadoes. It's no big deal that Accuweather supposedly issued a so-called "tornado warning" for Westar and the Kansas Turnpike Authority some "4 minutes" before Harveyville... they were doing similar warnings along the entire supercell's path when _no_ tornadoes had been occuring for over 2 hours, even with what Mike Smith referred to as "persistent tornadic signatures" (actually a parent mesocyclone with _potential_ to produce tornadoes). Many storms show persistent strong rotation without producing tornadoes.

The larger issue here is the public perception of "overwarning" that came out of the Joplin tornado NWS assessment. Many people at Joplin (including some I talked to) complained that sirens are run too often, fostering a public perception that they are hard to take seriously. The NWS is attempting to address that perception this spring, and that puts them in a difficult position on events like Harveyville. Mike Smith and Accuweather have none of that pressure... they can warn every location in a storm's path for their corporate clients whether reports verify or not and claim they did a better job than NWS, even when they have no responsibility for actual public warnings and overwarning perceptions.

The reality is, even with radars that have faster scans and better technology, the National Weather Service (and Accuweather) cannot in real-time discriminate between tornadoes and other severe phenomena in many situations. Some tornadoes are just too brief. The public needs to understand this and not expect someone to come "knocking on their door" to personally warn them for every potentially severe event. There _was_ a severe thunderstorm warning for Harveyville at the time of the tornado, and also a tornado watch in effect.

People should be prepared and responsible for their own safety by taking all warnings and watches seriously. They can then monitor cell phone alerts, radar, television, and/or weather radios for additional information to assess their risk rather than expecting sirens to warn them specifically for _everything_. If a strong supercell on radar with a severe thunderstorm warning is approaching and your town is directly in its path, you should be prepared to take cover _fast_, regardless of whether or not a tornado warning is in effect or the sirens are blaring.

Besides missing some important facts, the general tone of the article you wrote yesterday did not help in this regard, and comes off as promoting private for-profit corporatations like Accuweather that have none of the public resposibilities and pressures of the National Weather Service. The National Weather Service did a superior job with watches, warnings, and advance public awareness on the March 2nd tornado outbreak 3 days ago, and many lives were saved. You didn't mention that in your article, and instead focused on NWS performance in a single isolated weather event.

In the future, please consider writing articles that constructively deal with important issues such as:
- The reality that no weather organization or corporation can warn or alert the public on every severe event, particularly brief or isolated ones!
- The public perception of overwarning vs. the public desire and expectation to be properly warned on everything that affects them directly. How does one even approach a solution to this? These are huge social issues!
- What can we do about the public ignoring severe thunderstorm warnings?
- As discussed above, the National Weather Service has some category of watch or warning issued to alert the public on the vast majority of weather events. This was certainly true with the Harveyville tornado. If people want to stay safe, they need to take some degree of responsibility for themselves by monitoring available weather information and taking appropriate action instead of relying completely on sirens and/or specific warning "categories".

Rather than write attention-grabbing headlines ("there was no warning"), let's get the facts straight and not mislead the public about difficult-to-detect events. Instead, let's educate and encourage the public to monitor the available weather information we have (which is of good quality) and take some responsibility for themselves.

Excellent post, as always. It does seem, though, that your hyperlink to the original article is missing? Not that you want to promote this guy, but it's a bit difficult to put your email in context without reading the original article.

Keep up the great work!


Jon Davies said...

John: mistake. I added the link. Thanks!

Jon, Perfect post. It is most important that the public acts in advance and makes themselves aware of weather events that could impact them. They must take the responsibility for their own safety. The "without warning" hype leads people to believe nothing could have been done to prevent it, which is furthest from the truth. Glad you pointed out the SVR Tstorm warning and Tor watch were in place prior.

So are you saying that everyone should take cover if they are under a severe thunderstorm warning just because a severe thunderstorm can quickly produce a tornado without any warning? I don't know anyone that would take cover in a severe thunderstorm warning like they would for a tornado warning. Sure, they may get away from windows and take some minor precautions, but in no way can you blame the public for not taking cover if a tornado warning was not issued. Sure, there wasn't much the NWS could do due to the brief nature of the tornado, but you come off sounding like you are blaming the public for not taking shelter because they were under a severe thunderstorm warning. A severe thunderstorm warning is NOT a tornado warning, regardless of whether or not the warning mentions a tornado could quickly form. In 99+% of severe thunderstorm warnings, there is no tornado. How can you expect the public to take cover like they would for a tornado if they are just under a severe thunderstorm warning? While you do have some good points, I feel you are misunderstanding how the public reacts differently to severe thunderstorm warnings and tornado warnings.
