Message elements

How the first alert is built

To check this alert, SuperGrok Heavy 4.5 (an AI) read it in full 25 separate times, independently. Each read decided whether the message answers each of the six questions and gave a short reason. A final reviewer then weighed all 25 and wrote the plain-English verdict you see when you open a row. The score (for example 22/25) is how many reads agreed; the 25 individual reads are tucked underneath if you want to check them.

UIS Emergency Alert: Severe weather approaching UIS. Seek shelter now. The National Weather Service has issued a Severe Thunderstorm Warning until 2:00 PM for Sangamon County.

  • Sourcepresent25/25

    Final assessment

    Seek shelter now is an explicit protective-action order.

    Who is sending the alert and who is responding. People act faster on a message from a clearly identifiable, credible sender, such as a named department, the police, or a branded alert system, than on an anonymous notice. A branded signature counts.

    See all 25 individual reads
    1. present: The clause Seek shelter now is an explicit protective-action order, so shelter is present.
    2. present: Readers are told to take shelter immediately; that is the shelter element.
    3. present: A campus emergency product that says Seek shelter now carries a shelter instruction.
    4. present: Protective movement indoors is commanded by the three-word Seek shelter now line.
    5. present: The alert does not merely describe weather; it orders shelter, satisfying S.
    6. present: S is present because the transmitted body contains a direct seek-shelter imperative.
    7. present: Shelter-in-place / seek-shelter language appears verbatim as Seek shelter now.
    8. present: The action the recipient must take is to seek shelter, which is the S element.
    9. present: This is a life-safety shelter command, not an informational weather headline only.
    10. present: Presence of Seek shelter now is sufficient for a present shelter verdict.
    11. present: The product's operational purpose is to get people into shelter right now.
    12. present: An imperative shelter instruction is on the face of the message.
    13. present: S=1: the community is directed to shelter, not merely warned that storms exist.
    14. present: The UIS Emergency Alert includes a shelter-now command after naming incoming weather.
    15. present: Protective-action coding: seek shelter is stated, so the shelter bit is on.
    16. present: Unlike a watch-only notice, this one tells people to seek shelter now.
    17. present: The second sentence is a shelter order; that is the S signal.
    18. present: Shelter element hits because the body tells the audience to seek shelter immediately.
    19. present: A present S vote follows from the explicit Seek shelter now wording.
    20. present: No inference required: shelter is the named action in the text.
    21. present: S present - the alert's core instruction is to seek shelter.
    22. present: The phrase Seek shelter now is unambiguous protective guidance of the shelter type.
    23. present: I mark shelter present solely because the message orders it.
    24. present: Campus-directed shelter language is in the first two sentences.
    25. present: S is coded present from the seek-shelter imperative, independent of the NWS clause.
  • Hazardpresent25/25

    Final assessment

    Severe weather / Severe Thunderstorm Warning names the hazard.

    What the threat actually is. A complete warning names the specific danger, such as a shooter, a fire, a tornado, or a gas leak, rather than a vague emergency, because people decide what to do based on what they are facing.

    See all 25 individual reads
    1. present: Severe weather and Severe Thunderstorm Warning name the meteorological hazard.
    2. present: The hazard is a severe thunderstorm as issued by the National Weather Service.
    3. present: H is present: severe weather approaching plus a named SVR product.
    4. present: Thunderstorm warning language identifies the threatening phenomenon.
    5. present: The alert specifies severe weather, which is the hazard class.
    6. present: NWS Severe Thunderstorm Warning is an explicit hazard label.
    7. present: Hazard coding turns on the words severe weather and Severe Thunderstorm Warning.
    8. present: A storm/thunderstorm threat is named, so H is present.
    9. present: The message is not a crime or fire notice; the hazard is severe weather.
    10. present: H=1 because the body names the weather threat rather than leaving it implied.
    11. present: Severe thunderstorm is the hazard noun phrase in the NWS sentence.
    12. present: Incoming severe weather is stated up front, satisfying hazard.
    13. present: The product identifies what people are sheltering from: a thunderstorm warning.
    14. present: Hazard present via both colloquial severe weather and official SVR wording.
    15. present: A meteorological hazard is on the page: thunderstorm warning for the county.
    16. present: H hits on Severe Thunderstorm Warning as the named danger.
    17. present: Weather-hazard language is explicit, not reconstructed.
    18. present: The NWS product type is itself the hazard identifier.
    19. present: Severe weather approaching UIS names the threat to the campus.
    20. present: I treat Severe Thunderstorm Warning as sufficient hazard specificity.
    21. present: H present: thunderstorm, not a vague emergency with no phenomenon.
    22. present: The body twice marks weather as the danger (severe weather; thunderstorm warning).
    23. present: Hazard element is satisfied by the official warning name.
    24. present: A present H vote follows from naming a severe thunderstorm.
    25. present: No other hazard type is mentioned; the weather hazard is clear.
  • Locationpresent25/25

    Final assessment

    UIS and Sangamon County locate the product.

    Where the threat is. Saying whether danger is in a specific building, a part of campus, or area-wide lets people judge their own proximity and choose a safe direction. Without a where, a warning is hard to act on precisely.

    See all 25 individual reads
    1. present: UIS is named as the place the weather is approaching, and Sangamon County is the warning polygon.
    2. present: Location is present: campus (UIS) plus county (Sangamon).
    3. present: The alert scopes the warning to Sangamon County and the UIS campus.
    4. present: L=1 because both UIS and Sangamon County appear as geographic anchors.
    5. present: Recipients can tell this applies to UIS / Sangamon County, not a statewide blast.
    6. present: Campus name UIS plus county name give a usable location.
    7. present: Location coding: approaching UIS and for Sangamon County.
    8. present: The geographic target is the Springfield campus area in Sangamon County.
    9. present: L is present via two place names, UIS and Sangamon County.
    10. present: A county-level warning plus campus name is enough location.
    11. present: The text says the warning is for Sangamon County, locating the product.
    12. present: UIS in the first sentence is a campus location marker.
    13. present: Place is not omitted: UIS and Sangamon County are both written out.
    14. present: Location present - the warning footprint is Sangamon County at UIS.
    15. present: Unlike a no-place NWS relay, this one names UIS and the county.
    16. present: L hits because the audience is told where the warning applies.
    17. present: Geographic specificity: campus identifier plus county.
    18. present: Sangamon County is the official warning area; UIS is the campus hook.
    19. present: I mark location present from UIS and Sangamon County together.
    20. present: The product is place-bound, not a generic national weather tweet.
    21. present: Location element is satisfied by the campus and county strings.
    22. present: Two toponyms (UIS, Sangamon County) carry the L bit.
    23. present: L=1: approaching UIS ... for Sangamon County.
    24. present: A reader in another county would know this is not for them.
    25. present: Present location vote from explicit campus and county references.
  • Guidanceabsent0/25

    Final assessment

    No additional how-to beyond the shelter imperative already coded as S.

    The protective action to take. A clear, specific instruction, such as shelter in place, evacuate, avoid the area, or run-hide-fight, drives faster and more correct protective behavior than describing the threat alone.

    See all 25 individual reads
    1. absent: No extra how-to (lowest floor, interior room, away from windows) beyond seek shelter.
    2. absent: Guidance beyond the shelter imperative is absent; seek shelter is coded on S, not G.
    3. absent: G is off: there is no secondary instruction set after Seek shelter now.
    4. absent: The message does not explain how or where to shelter inside a building.
    5. absent: No avoid-area, evacuate, or detailed protective steps appear.
    6. absent: G=0 because the only action is the shelter command already counted as S.
    7. absent: Further guidance (routes, buildings, check-in) is not in the body.
    8. absent: A one-line shelter order without extra steps fails the G element.
    9. absent: No stay-away-from-windows or basement language is present.
    10. absent: Guidance element requires more than the shelter verb; that extra is missing.
    11. absent: The NWS sentence is hazard/time/place, not additional protective how-to.
    12. absent: I do not double-count Seek shelter now as both S and G.
    13. absent: G absent: no operational extras like classes canceled or roads to avoid.
    14. absent: The text stops at seek shelter; it does not coach the sheltering method.
    15. absent: No multi-step guidance appears after the shelter line.
    16. absent: G is not present when the only instruction is the shelter imperative.
    17. absent: Unlike products that add go to lowest level, this one has no such clause.
    18. absent: Secondary guidance is not written; G stays off.
    19. absent: I mark G absent for lack of any instruction besides seek shelter.
    20. absent: No building-level or movement details are given.
    21. absent: The alert does not tell people what to do after they seek shelter.
    22. absent: G=0: no extra protective or operational guidance layer.
    23. absent: A bare seek-shelter plus NWS citation is not additional guidance.
    24. absent: Guidance coding stays false without a second distinct instruction.
    25. absent: Nothing in the body beyond shelter, hazard, place, and time.
  • Timepresent25/25

    Final assessment

    Until 2:00 PM is an explicit warning end time.

    When the message applies. A timestamp, the word now or immediately, or a phrase like until further notice tells the reader whether the danger is current and how quickly to act.

    See all 25 individual reads
    1. present: Until 2:00 PM is an explicit expiration clock for the warning.
    2. present: Time is present via the 2:00 PM bound on the thunderstorm warning.
    3. present: T=1 because the NWS product is given an until-time.
    4. present: The warning window ends at 2:00 PM, which is a temporal bound.
    5. present: A clock time (2:00 PM) appears in the transmitted text.
    6. present: T hits on until 2:00 PM rather than an open-ended watch.
    7. present: The duration/end of the hazard is stated as 2:00 PM.
    8. present: Time element is satisfied by a specific hour on the clock.
    9. present: Until 2:00 PM tells recipients how long the warning lasts.
    10. present: A present T vote follows from the named end time.
    11. present: The product is time-bounded, not just now without an until.
    12. present: 2:00 PM is the temporal datum in the last sentence.
    13. present: T present: warning valid until a stated clock time.
    14. present: The NWS clause includes an until-time, which is T.
    15. present: I code time present solely from until 2:00 PM.
    16. present: A clock-hour bound is in the official warning restatement.
    17. present: Temporal specificity is 2:00 PM, sufficient for T.
    18. present: The message tells people the warning lasts until 2:00 PM.
    19. present: T=1: until 2:00 PM is not ambiguous relative time like soon.
    20. present: An absolute clock time is printed, so time is present.
    21. present: The warning's end is dated to 2:00 PM in the body.
    22. present: Time coding turns on the until 2:00 PM phrase.
    23. present: Recipients know the protective window through 2:00 PM.
    24. present: T is on because a clock deadline is written out.
    25. present: No inference of duration is needed; 2:00 PM is stated.
  • Impactabsent0/25

    Final assessment

    No crime/suspect/identity payload; weather is the hazard element.

    What the hazard could do to the people in its path. Beyond naming the threat, a complete warning conveys its potential consequences or severity, such as that a tornado can level buildings or that a leak could be explosive, so recipients grasp how much danger they are in. Research on warning message content finds that a concrete impact statement helps people personalize their risk and act sooner.

    See all 25 individual reads
    1. absent: No crime, suspect, or named incident identity beyond the weather product.
    2. absent: I is off: a thunderstorm warning is the hazard, not an identity element.
    3. absent: There is no person, building incident, or crime to identify.
    4. absent: Identity/incident-specifics (suspect, victim, case number) are absent.
    5. absent: I=0 because NWS SVR is not an identity-bearing incident description.
    6. absent: The alert does not name a unique criminal or fire event.
    7. absent: No who/what identity beyond the generic weather warning type.
    8. absent: I stays false on a meteorological relay without a discrete named incident.
    9. absent: Identity element is for actors or specific events, not county weather.
    10. absent: Nothing here identifies a person, vehicle, or unique case.
    11. absent: I absent: no suspect description, no building fire name, no crime.
    12. absent: A thunderstorm warning is typed hazard, not an identity payload.
    13. absent: The body has no incident identity distinct from the weather hazard.
    14. absent: I do not treat NWS product names as the I element.
    15. absent: No individualized incident (robbery, shooting, leak) is described.
    16. absent: Identity coding remains off for this weather-only product.
    17. absent: There is no named perpetrator or unique case identifier.
    18. absent: I=0: weather phenomenon is H, not I.
    19. absent: The message lacks identity details such as names or descriptions of people.
    20. absent: No discrete non-weather incident is identified.
    21. absent: I is not present in a county thunderstorm warning restatement.
    22. absent: Absent identity: no who besides NWS as the issuing agency.
    23. absent: Issuing agency (NWS) is not an incident-identity element.
    24. absent: I mark I absent; this is a weather EN without identity content.
    25. absent: No identity facts to code beyond the already-counted hazard.
