University demonstrates questionable understanding of tornado warnings

It’s really important that anyone who is in charge of the safety of an institution — a university campus, for example — maintain an updated, working knowledge of how weather warnings work. Tweets sent today by Indiana University today could lead one to believe that its campus safety staff could benefit from some education in that area.

At 1:19 p.m. EST, the Indianapolis office of the National Weather Service (NWS) issued a tornado warning that included a portion of southern Monroe County, Indiana.  The warning came with a polygon that clearly showed that the IU campus was not included.

Polygon associated with Nov. 5 tornado warning near Bloomington, IN. The National Weather Service issued the warning only for the area inside the red polygon.

In addition, the text of the warning indicated that “a severe thunderstorm capable of producing a tornado was located 12 miles northwest of Bedford, moving east at 30 mph.” In other words, the storm was not moving toward Bloomington or the IU campus (which is why NWS meteorologists drew the polygon as they did).

Six minutes after the NWS issued the warning, IU sent a tweet at 1:25 regarding what it called a “tornado warning for Bloomington.”

Cody Kirkpatrick, an IU lecturer in atmospheric science, attempted to clarify IU’s tweet:

The IU Twitter account replied:

Dr. Kirkpatrick knew what he was talking about. Those sending tweets on behalf of IU demonstrated ignorance of the National Weather Service’s “storm-based warning” system. When the NWS implemented that system a decade ago, it replaced the county-wide warnings to which IU’s tweet refers, with warnings based on polygons that indicate where the actual risk is.

In subsequent tweets, Dr. Kirkpatrick attempted to point that out, as well as the fact that IU’s original tweet was ambiguous. IU’s response:

But is warning people who are not at risk really better than warning only people who are truly at risk? Is doing so truly “safe,” or does it exacerbate existing challenges with getting people to respond appropriately to warnings?

The people at any institution like IU, who are in charge of disseminating public safety information, would do well to take full advantage of the informational resources that exist among their own faculty. Doing so could lead to better weather safety communications in the future.

Winter storm Twitter feeds to monitor

I set up some Twitter search strings in Hootsuite to help me watch what’s going on with this weekend’s winter storm. Here are links to the same searches on the Twitter website, which anyone can monitor, even those who don’t have Twitter account:

What’s the #1 source for national weather?

Amateur-run Facebook pages should not mislead readers into believing that their information is better than that of the National Weather ServiceShould a Facebook page run by amateur storm chasers promote itself as the best source for weather information? I can’t help but wonder how many (if any) naïve Facebook users foolishly rely on such pages for time-critical safety information, in lieu of the National Weather Service (NWS).

Recently, a Facebook page distributed the graphic above. I’ve blurred out identifying information, because who it was doesn’t matter to the point of this article. But the headline, “The #1 Source for National Weather” certainly caught my eye.

I’ve tried multiple times to contact the owners of the Facebook page that published that graphic. I sent a Facebook message and sent an email message to the email address on their website. I’ve received no response. So, all I know about them is what I see online.

From what I see, both the Facebook page and associated website are published by a group of amateur storm chasers, none of whom appear to have a meteorology degree.

In the U.S., only one source of weather information has the authority to issue the official watches and warnings that trigger weather radios, etc.

Don’t read what I’m not writing! There’s nothing wrong with an amateur-run Facebook page or website distributing interesting or important weather information. I do it all the time on Facebook, this blog, Twitter, etc. What I don’t do, however, is claim that my information is any better than others’.

Why? Because I don’t want anyone to assume that my blog, Facebook page or Twitter feed (or anyone’s for that matter) is a safe and reliable way to get timely, live-saving weather alerts, especially NWS warnings. Not even the NWS’ own Facebook and Twitter feeds are timely enough for that (yet).

That’s also why I consistently encourage readers – for their safety – to maintain timely access to NWS products (e.g. via NOAA Weather Radio, smartphone apps triggered by NWS products, Wireless Emergency Alerts, etc.).

All of us who publish weather information on social media and other Internet channels have a responsibility to inform and remind readers that in the U.S., only one source of weather information has the authority to issue the official watches and warnings that trigger weather radios, etc.: The National Weather Service. Likewise, we must not publish anything that could potentially mislead readers into believing that our social media feeds can keep them as safe as do directly received NWS warnings.

Our readers’ lives could depend on it!

NWS plans Twitter commemoration of Palm Sunday tornado outbreak

If you follow the the northern Indiana office of the National Weather Service on Twitter (@NWSIWX) and if your smart phone beeps at you every time the office tweets, you might want to change your settings before tomorrow.

The office plans to send more than 100 tweets to mark the 50th anniversary of the April 11, 1965 Palm Sunday tornado outbreak that killed 145 people in Indiana. No other tornado outbreak in the state’s history has killed that many people.

The NWS office plans to send tweets in real time, as if it were live tweeting during the actual outbreak. Every tweet will include the hash tag #PalmSunday50. This will give followers a feel for how NWS received information that day and the warnings it issued.

You can follow along, whether or not you have a Twitter account. The tweets will be visible at either of the following Web URLs:



The NWS office has also created a special website that provides detailed information about the outbreak, including photos like the one at the top of this post and first-hand accounts that witnesses provided the NWS.

Tweet responsibly during severe weather

Tornado clip art with Twitter bird logoDuring periods of severe weather, the micro-blogging service, Twitter often explodes with information. Some tweets are helpful, others are less so.

The “Virtual Operations Support Group” blog posted an excellent article last year, “How to Tweet Responsibly in Severe Weather” that every Twitter user should read before the next severe weather event happens.

Highlights include:

  • Include the Twitter handle of your local NWS office when reporting weather.
  • Include a time stamp with on any tweet about an NWS warning and any tweet that contains a severe weather report.
  • In weather reports, also include:
    • What you saw.
    • Where it happened.
    • A photo, if possible.
  • Even if you normally prohibit Twitter from knowing your location (for privacy), enable location services while tweeting about severe weather.
