Questions for the Extreme Wind Warning Module (choose the best answer)
1. As dangerous tropical cyclone winds approach, WFOs should provide frequent and increasingly
detailed short-fused products within the 00-03 hour time period because:
a. It validates the longer-fused tropical cyclone warnings which are already in effect.
b. It is during this time that WFOs know the most regarding expected local wind impacts.
c. The purpose is to try to overwhelm users with needless wind information.
d. None of the above.
2. According to the NOAA/NWS Glossary, Mesoscale Convective Systems can be either round or
linear in shape and include both tropical cyclones and squall lines.
a. True
b. False
3. With regard to conveying detailed wind information via short-fused products, what is the value of
operationally addressing tropical cyclones as Mesoscale Convective Systems?
a. It makes effective use of the preceding hours and moments leading up to a wind event.
b. WFO meteorologists remain focused on the most impacting aspects of the wind event.
c. Users remain focused and receive frequently updated wind information of relevance.
d. A flow of detailed information is useful for managing the safety of a sheltered population
throughout the entire wind event.
e. It heightens public readiness for the potential issuance of the EWW.
f. All of the above.
4. The Extreme Wind Warning (EWW) is issued for tropical cyclone sustained winds of _____ knots
or greater.
a. 64
b. 83
c. 100
d. 115
5. Within the defined warning area, the purpose of the Extreme Wind Warning (EWW) is to inform
people of the urgent need to:
a. Move to the safest place within their shelter and protect their head and body.
b. Board up windows and brace exterior doors of their home.
c. Run from these dangerous winds.
d. Stay in the center of a large open-span room and continue playing cards.
6. Since frequent gusts to 100 knots can have a destructive battering effect upon well-built homes
and shelters, these gusts should be:
a. Totally ignored since they are not sustained winds.
b. Included within the EWW polygon to help define its flanks and inland depth.
c. Mentioned within short rapid-fire statements that support the EWW and coincident with
extreme sustained wind information.
d. Both b and c.
7. Why is it important to include the Extreme Wind Warning (EWW) concept within NWS Hurricane
Preparedness Talks and Hurricane Disaster Planning?
a. Because extreme tropical cyclone winds are infrequent to rare occurrences.
b. Because it helps families and communities focus on appropriate shelter when creating
their disaster plans.
c. Because it is not feasible to evacuate everyone located within long-fused warning areas,
even when major hurricanes threaten.
d. All of the above.
8. To better anticipate the likely size and orientation of impending Extreme Wind Warning (EWW)
polygons, warning meteorologists should make every effort to determine the actual distribution of
100 knot winds about the core of the cyclone within 2 to 3 hours of landfall.
a. True
b. False
9. When issuing an Extreme Wind Warning (EWW), the ideal lead-time is __________, with a valid
period around __________.
a. 24 hours; 2 hours
b. 2 hours; 1 hour
c. 1 hour; 2 hours
d. None of the above.
10. Within the eyewall of landfalling major hurricanes, areas of enhanced convection should be
closely scrutinized since they:
a. Often have a direct correlation with areas of enhanced damage.
b. Are fun to track on weather radar.
c. Can vertically transport higher momentum air down to the surface.
d. Both a and c.
