3. Post Storm Survey (PSS)
Motivation
“Need a process by which WFO [Weather Forecast Offices] can
systematically gather local customer input and local research
results … and turn that information into improved products and
services” Ray Wolf – Science and Operations Officer (Science Operations
Officer) NWS WFO Davenport, IA
Goal
Improve communication & effectiveness of winter weather
information and threat by gaining insight into perceptions and
decision making processes related to hazardous winter
weather.

4. The Post Storm Survey
 Not a Critique of Forecast Accuracy
 Rather, asks a few Specific Questions
How did you received the winter storm information

How did you perceived the threat of the storm

What steps did you take to prepare for the storm

How did your plans changed due to the storm


5. Test Season
March-April 2008
 Only included winter storms that Affected Duluth,
MN Forecast Area
 Proposed for Winter Events Requiring a “Warning.”
 Didn’t quite work that way…No Storms.
 Winter finally arrive March & April 2008
 Posted Survey for Three Winter Events
• One case (March 18th) did not have a Warning but was
still used in Test season data
• All 3 Cases were in NE Minnesota (Duluth Area)
Received over 500 responses Total


6. Post Storm Survey

28. Interesting perception…
“I live in Northern MN, a snow storm with
25” is not a big deal.”
These kind of open responses introduced the idea to
include a question along the lines of :
“On a scale from 1 to 10, how does this storm compare to
typical winter storm in this area?
Please select a number from 1 to 10, with 1 meaning this was a very
common storm and 10 meaning it was an extremely rare storm.

29. Test Season Conclusions
 Significant number of respondents stated they altered
their routine because concerned about road
conditions/travel.
 People did not perceive the meteorlogic terminology
such as sleet and freezing rain as the threat;
because not a direct impact?

 There was an increase in preparedness (gas, food water,
communication) with highly anticipated blizzard versus
low impact snow advisory
 Climatology plays major factor…What is viewed as
“normal” for winter?
