In the December issue of Allen County HamNews, I hinted at a possible change in reporting criteria for SKYWARN spotters. During a conference call with leaders of IMO SKYWARN, NWS Warning Coordination Meteorologist Michael Lewis discussed a goal for spotter reports. Lewis wants reports to be based more on weather impact than on measurements such as wind speed or hail size. For example, if the weather does damage or causes injury, Lewis wants to know about it, even if conditions do not meet traditional reporting criteria.
NWS Announces Plans for Local SKYWARN Training
- Why to report
- What to report
- How to report (including telephone, ham radio, etc. and new tools like social media)
- Where to obtain the reports of others (for situational awareness)
- Skywarn Spotter Training — https://www.meted.ucar.edu/training_course.php?id=23 — (a two-module course including modules on the role of the spotter and basics of convection)
NWS SKYWARN Training Suspended, SKYWARN Operations Continue

Are Ham Radio SKYWARN Spotters Becoming Irrelevant?
- Education. By learning all we can about meteorology, we can assure that all our reports are valid and valuable.
- Technology. By becoming familiar with and using other technologies to supplement ham radio (e.g. tweeting photos from smart phones), we can provide a more complete service while demonstrating our ability to stay on the “cutting edge.”
- Procedures. By insisting on sounding as professional as possible when we communicate, we can build credibility among any IWT members who monitor or receive our reports.
Keeping the Mic on its Hook
Storm Spotters as Advocates
If you’re a trained SKYWARN storm spotter, who in your family knows more than you about severe weather? How about in your neighborhood, place of employment or place of worship?
Unlike most of your family, friends and coworkers, you know that a tornado watch means that conditions are favorable for the development of tornadoes and a tornado warning means it’s time to take cover. You know that flooding kills more people in northern Indiana than do tornadoes. You know that most people cannot rely on tornado sirens to warn them of danger.
Chances are, in most (if not all) of your circles, you are the severe weather expert.
I’d like to propose, therefore, that you have more responsibility than observing and reporting severe weather. You should also be a weather safety advocate.
I wrote in a previous post that many residents of Joplin, Missouri initially ignored warnings of the tornado that would devastate part of their city. Compared to years past, the National Weather Service is able to issue more specific warnings earlier than ever before. But for too many people, these advances are wasted, because they don’t know how to react to the information. That’s where you come in.
Be an advocate. Advise your friends and family to buy weather alert radios. Help program the radios. Help them learn how to interpret and react to severe weather information. Make sure they know that a tornado warning means “take shelter,” not “go outdoors to look.” Teach them they’re not necessarily in the clear just because 10 minutes have passed without a tornado.
We can be the best possible weather spotters but if the people we’re trying to protect don’t know what to do, what’s the point?
Respect for Storm Chaser Reed Timmer

| Storm Chaser Reed Timmer |
He gave an excellent presentation that focused on the science he does when he’s chasing. Yes, he does real science; he doesn’t just pay it lip service. I’ve attended several symposiums to further my education beyond what the NWS provides in basic spotter training but I still learned some things from Reed’s talk. His discussion of suction vortices in tornadoes was particularly interesting. So was his data plot that showed wind speeds during a tornado intercept dropping to 8 MPH and then increasing to 138 MPH (or was it knots … I don’t remember) in a second or less.
“Warning Desensitization” Makes SKYWARN Spotters even more Important
Tornado warnings issued before and during the Joplin tornado. Notice how some of the warning polygons overlap. Graphic courtesy NWS.
Garnet reported that due to warning desensitization, most Joplin residents did not take immediate action when they learned of the NWS tornado warning. Instead, most sought additional information, including going outside to look for the storm, eating away at the 21 minutes between the warning and the beginning of EF-4 tornado damage.
Some Information Regarding March 2 Indiana Tornadoes
While tornadoes were slamming southern Indiana March 2, I was in a severe weather symposium in Columbus, Ohio. How ironic is that? Everyone in the room was using laptops, tablets and smart phones to keep eyes on the situation. One of the meteorologist presenters volunteered to give us all a meteorological briefing on the situation during lunch. It was fascinating. I’ll write more about the symposium and some interesting stuff I learned in another post.
After I got home, some Fort Wayne hams were talking on VHF and UHF about what kinds of communication support they be asked to provide as a result of the disaster. Based on a SITREP-style news release that the Indiana Department of Homeland Security (IDHS) put out just before midnight, it appears the answer is, “not much:” “Communications: Only limited communication issues are being reported at this time.”
IDHS is posting updates regarding the disaster on their Facebook page. You don’t have to be a Facebook member to see the updates. Go to:

Learned Something New: Book Traffic to Multiple Stations
I’ve been handling traffic since the 1970s but I still learn new things about this aspect of ham radio. While listening to other traffic handlers on a net, I often ask myself, “Is that the right way to do that?” Then I go online to the NTS Methods and Practices Guidelines (MPG). That document provides information about nearly every aspect of traffic handling, in excruciating detail!
Just the other day, I heard one of our fellow traffic handlers check in with “book” traffic for three disparate locations in the section. In my experience, we “book” messages when multiple messages that share common parts (e.g. the same text) will be sent to a single station. It turns out my experience was incorrect.
I went to the MPG and learned something! Chapter Two (section 2.3.4.12) provides a procedure for sending a book of three messages to three different stations on voice. It goes something like this, where W3XZ is sending a book to W3XA, W3XB and W3XC:
W3XZ: “W3XA, ready to copy?”
W3XA: “Ready.”
W3XZ: “XB?”
W3XB: “Ready.”
W3XZ: “XC?”
W3XC: “Ready.”
W3XZ: “Book of three, routine, hotel x-ray golf, whiskey bravo five november kilo delta, two one, Oklahoma City, Oklahoma, February 29. Break.” (Pauses for any fill requests and if receiving stations are silent, continues.)
(Note that I’ve written this as you’d say it on the radio, not as it would be written on a radiogram form. Also note that we say, “Book of (number of messages in the book)” where we’d normally say a message number. The receiving stations don’t write that part down. They start writing with the “R” for “routine.”)
W3XZ: “Message relay stations are needed, initial x-ray. Hope you are able to, I spell, tango oscar, help, initial x-ray. Find a local net to, I spell, tango oscar, learn how. Figures seven three. Break. Pat, amateur call whiskey bravo five november kilo delta. Break” (Pauses again for fills, continues if receiving stations are silent.)
(Note that the word “break” does not mean “over,” as it sometimes does in QSOs. In message sending, “break” simply means that one part of a message is finished and the next is about to begin. We pause after some “breaks” (but not all) to allow receiving stations to ask for fills. If receiving stations need no fills, their silence tells the sending station to continue. Note that there is no pause after the “break” before the signature. We assume receiving stations can wait a few more seconds to request fills. Also, note that after the signature, we do not say “end” as we would during a single radiogram. This is just one part of a book, so we say “break” instead. Also note that “to” is spelled phonetically to distinguish it from “two” and “too.”)
W3XZ: “W3XA, number fifty five, Jim Smith,” (continues address block for message number two)
W3XZ: “Break. W3XA?”
(This “break” indicates the end of the address block and therefore the end of the stuff that W3XA must copy. W3XZ gives W3XA’s call sign, inflecting the question mark, to inquire whether W3XA copied the message.)
W3XA: “Roger, W3XA.”
Now, W3XA is finished and has legally signed off with his call sign. If this message was being passed on a frequency other than the net frequency, W3XA then returns to the net frequency. Next, W3XZ continues as above, sending the unique parts of message number 56 (the second message) to W3XB and message number 57 (the third and final message) to W3XC. The only difference is in what W3XZ says at the end of the third message’s address block. Instead of, “Break. W3XC?” W3XZ would say, “End book, no more.” He says “end book” instead of “break” because there’s nothing more to send to anyone. He doesn’t need to say “W3XC?” because W3XC is the only station remaining and knows that after he hears “End book no more” it’s his turn to say “Roger, W3XC.” After W3XZ hears that final “roger,” he signs off with his call sign.
This procedure looks pretty complicated but if you look through it and try it a couple of times, you’ll get the hang of it. And it can save a lot of time on a voice net!
