2008 WISCONSIN TORNADO & SEVERE WEATHER
AWARENESS WEEK
Governor Doyle has
proclaimed April 21-25, 2008 as Tornado and Severe Weather Awareness
Week in Wisconsin. On April 24, 2008, a statewide tornado drill is
planned. The National Weather Service will issue mock tornado watches
and warnings. If actual severe weather occurs anywhere in the state
on April 24, the tornado drill will be postponed until Friday, April
25 with the watch/warnings issued at the same times. Below are the
scheduled times for the mock watches/warnings.
(Feb. 5, 08)
1:00 pm - MOCK
TORNADO WATCH FOR ALL OF WISCONSIN.
1:10-1:15 pm - National Weather Service Green Bay issues mock
tornado warning for Brown, Calumet, Door, Florence, Forest, Kewaunee,
Langlade, Lincoln, Manitowoc, Marathon, Marinette, Menominee, Oconto,
Oneida,
Outagamie, Portage, Shawano, Vilas, Waupaca, Waushara, Winnebago and

WISCONSIN FREEWAY BACK-UP ASSESSMENT
Wisconsin's Department of Military Affairs has released its assessment
on the Interstate 39/90 back-up between Madison and the Illinois
border during the severe February 5-7, 2008 winter storm. This event
required Governor Doyle to declare a state of emergency. This is an
exceptionally well detailed assessment on how effective (or
ineffective) various Wisconsin agencies performed to the traffic and
public safety issues during near blizzard like conditions. While
lengthy (164 pages, 3.14 MB) there are segments of interest for local
first-responders, law enforcement, fire departments, emergency
response personnel, plow and wrecker operators, state troopers, media,
the National Guard, and Wisconsin weather watchers alike.

JANUARY TORNADOES
A rare tornado out
break hit southeast Wisconsin, Northern Illinois, Missouri, and
Oklahoma on January 7th.The strongest was rated EF-3 for southeast Wisconsin.

SPOTTERS GET NEW REFERENCE POINTS
Spotters in south central and southeast
Wisconsin report their location based on their distance and
direction from a city center or geographic landmark. Beginning in 2008
new additional points will be
added to the list. These new points will now include airports,
institutional landmarks, and state parks.
Spotters served by the Milwaukee-Sullivan NWS office should link to
the Milwaukee Skywarn webpage
http://www.mke-skywarn.org/cities.htm and
review these new points.

HIGH VISIBILITY GARMENTS FOR
SPOTTERS-CHASERS-MEDIA?
On November 24th, 2008
Federal Highway
Administration (FHWA) regulation 23 CFR 634 goes into effect. It
requires the
wearing of high visibility garments on all federally funded highways.
This is a compliance issue for public safety, the towing and recovery,
road construction and maintenance industries. Its impact on spotters,
chasers, and media spotters have yet to be determined.
(1/6/08)
WEATHER RADIOS FOR ALL MOBILE HOMES?
The House of
Representatives, by voice vote, has pass legislation that would
require weather radios in all mobile homes. The Senate has yet to act
on the bill. As of April 2007 Indiana passed a similar statewide law
for mobile homes known as "CJ's Home Protection Act." Critics of the
new bill note the proposed legislation provides helpful warning
information, but no solution since many mobile home parks do not have
storm shelters, and that driving from a oncoming storm can be equally
dangerous. According to the bill, some 20 million Americans live in
manufactured homes and the fatality rate for such homes during storms
is more than 10 times that of permanent structures.
(A-P, 10/30/07)
CROSSING POLICE LINES (Wisconsin Radio & TV
Engineers Note)
The Wisconsin Broadcasters
Association and the Wisconsin Department of Justice, division of
Criminal Investigations
are providing state-issued Broadcast Emergency Personal ID cards to
radio and TV engineers. The cards will aid broadcast engineers in
passing thru police lines to access broadcast transmitters to keep
their stations on the air to broadcast emergency information during a
disaster.
This is in response to recommendations following the Hurricane Katrina
disaster when engineers had problems reaching their transmitter sites.
This program is not for reporters, but only radio and TV engineers.

CAPSULE UPDATE – September 2007
FROM COUNTY TO STORM BASED WEATHER WARNINGS
By Skip Voros,
Executive Director, Milwaukee Area Skywarn Association
The National Weather
Service currently issues and disseminates warnings for severe
thunderstorms, tornadoes, and flash floods using full county or parish
boundaries. In order to improve the accuracy of warnings for these
hazards, the NWS will implement Storm-Based Warnings on October 1,
2007. Although entire county warnings are still possible with some
storms, beginning in fall the warned area will be in the shape of a
multi-sided box (polygon) indicating the greatest threat area
regardless of the geopolitical boundaries. Thus areas not affected by
the storm's path do not get warned. Pictures and overview at:
http://www.weather.gov/sbwarnings/
-MORE-
During active severe weather events the polygon warning areas are now
displayed on internet radar for tornadoes, severe thunderstorms, flash
flooding, special marine events, and extreme wind warnings in
hurricane prone areas. Some TV channels are also displaying the
polygon warned areas. On-line at:
http://www.srh.noaa.gov/ridge/index_lite.htm and
http://www.srh.noaa.gov/ridge/index_lite.htm
-MORE-
In partnership with the private sector Storm-Based Warnings will
promote improved graphical warning displays, support a wider warning
distribution through cell phone alerts, pagers, and web enabled
Personal Data Assistants (PDA’s) etc. Audio and text warning formats
for NOAA radio, E-mail, and TV screen crawls will include more
specific geographic or landmark wording.
LIGHTNING INSURANCE CLAIMS INCREASING
The Insurance Information Institute recently released data about
payouts to home owners for damages caused by lightning strikes. In the
U-S, the number of claims in 2006 was 256,000. The total payout was
$882 million, which is about 30% higher than what was paid out in
2004. The increased costs are attributed to home owners with more
electronic entertainment options. The above losses don’t include
damages to non-residential properties, forest fire related, or fire
fighting costs.

COASTAL RESIDENTS WHO REFUSE HURRICANE
EVACUATION
A recently released Harvard School of Public Health survey found that
nearly one-third (31%) of residents in high-risk hurricane areas would
not leave if government officials issued an evacuation order due to
the threat of a major hurricane. Respondents gave the following
reasons: Their home is well built and would be safe (75%), the roads
would be too crowded (56%), the evacuation would be dangerous (36%),
worry their possessions would be stolen or damaged (33%), they would
not leave their pets (27%). The complete study is on-line at:

WEATHER RADIO RECALL
By US Consumer Product Safety Commission
On August 29th the US Consumer Product Safety Commission (CPSC)
announced the recall of about 66,000 weather radios manufactured by
Oregon Scientific incorporated. The complaint indicates the radios are
not activate a warning alert when issued by the weather service.

RIVER WATER LEVELS
Historic flash flooding occurred in southeast Minnesota (17 inches)
and western Wisconsin (11 inches) on August 18-19th. At least 7 were
killed and 12 counties now under disaster declarations. Local sheriffs
used NOAA All Hazards’ Weather Radio to issue emergency evacuations
orders. Is there a river in your area? Find out its level and trend

DRIVER AND SPOTTER SAFETY: Turn Around Don’t
Drown (TADD)
Many people believe their 3,000 pound car or
min-van is too heavy to float with 1 or 2 feet of flood water. But why
then does a 97,000 ton Aircraft carrier float? Vehicles, including
ships, float because of buoyancy. Most cars can be swept away with
18-24 inches of fast moving water, and trucks or SUVs do not fare much
better. For a simple explanation and graphic on buoyancy see:

DOPPLER RADAR TRAINING
By Rick
Swierczynski, Vice President & Associate Director, MASA
Inc.
Weather surveillance radar (RAdio Detection And Ranging) is used by
virtually all weather sensitive responders. However, with the
exception of knowing that the bright red colors often mean strong or
severe storms, most users do not fully comprehend weather service
radar imagery. Is your favorite radar image showing rain, hail, snow,
smoke plumes, lake breezes, migrating bird flocks, wheat chaff from a
farm field, damaging winds, or images that infer a rotating storm
(often a precursor to funnels and tornadoes).
On-line at
http://www.crh.noaa.gov/pub/wcm/Radar_training.ppt
(PowerPoint, 126 slides, 30 MB) it covers how radar works, basic and
severe storm imagery, and a quiz to test what you have learned.
Recommended audiences include: designated weather watchers, emergency
managers, police and fire, marine, spotter, water management,
agriculture, forestry, aviation, and public works personnel. Some
material and graphics will be difficult for the newcomer. For
additional Doppler radar training also see:

10 MORE REASONS FOR WEATHER SPOTTERS
By Peggy K., Secretary, Milwaukee Area Skywarn
Association
Because the Warren County Iowa community of Cumming does not have
tornado sirens or an emergency management plan according to a story by
Des Moines television station WHO.
Because current Doppler radar technology cannot determine the exact
size of hail. Rare and verified 5.5 inch stones fell in Wisconsin’s
Wood County on June 7th causing damage to roofs, cars, and crops.
Because communication lines go down. On June 27th a large part of
Oswego county New York lost cell, landline, cable TV, and 9-1-1 center
contact when a fiber cable was damaged. 20-thousand people were
without communications for many hours.
Because spotters only call 9-1-1 to make a report. During a July 16th
tornado warning for Jefferson County in southeast Iowa, the 9-1-1
center answered almost 100 calls in a 45 minute period. Questions
included: “Is the tornado siren being tested? Was there a real
tornado? Where was it? Is it safe to leave the shelter?” This
prevented dispatchers from handling other real emergencies. Well
prepared spotters and the public always have safety plans for their
home or work. And the practice KEEP UP not CATCH UP.
Because many trained spotters are ham radio operators with backup
power and direct radio contact with the weather service. A July 28th a
telephone outage at the Northern Indiana weather office prevented
potential reports from being passed. Any reports had to be relayed
thru local law enforcement.
Because spotters understand you don’t call 9-1-1 unless its an
emergency where you need police, fire, or emergency medical attention.
During a August 6th tornado warning for Rock County in southern
Wisconsin, the 9-1-1 center was bombarded with calls. “OK, the tornado
alarm….OK, Does that mean it's just a tornado warning or what? …..I
need to know where we're supposed to go….there's a tornado warning
going on…….Yeah, we've got a tornado warning in Rock County, out
east…..Now, is that Janesville? I was wondering, my TV is out and
everything.....is the tornado warning done? KEEP UP not CATCH UP!
Because tornadoes have occurred in all 50 states. On August 9th
several shorted lived 6:30 AM twisters tore thru Brooklyn, New York.
That city has not seen a tornado since the beginning of record
keeping. In Bethel, Alaska (400 miles west-southwest of Anchorage), a
funnel cloud was seen on August 20th.
Because many spotters are ham radio operators, and unlike cell phones,
the ham radio channels are not affected outages or overloads. The
historic flooding on August 19th in southeast Minnesota prompted this
Civil Emergency Message on NOAA Radio:

COUNTY
EMERGENCY MANAGEMENT. THE SHERIFFS DEPARTMENT REQUESTS THAT CELL PHONE
TRAFFIC BE KEPT TO EMERGENCY PERSONNEL ONLY. RESPONDERS COULD
EXPERIENCE
COMMUNICATION PROBLEMS OTHERWISE.
(During the Minneapolis Bridge collapse a similar request was made by
emergency responders.)
Because weakening storms and simultaneous computer glitches can mean
major property damage. As was the case on August 23rd in the Chicago
area when a decaying storm suddenly intensified to produce an 80-100
MPH microburst and the city sirens did not sound during a tornado
warning.
Because the August 29th siren test in Franklin County, Ohio,
discovered 37 dead sirens out 143. This according to the county’s
Emergency Management director and the Columbus Dispatch.
UNHAPPY T-V VIEWERS:
As seen on the Pittsburg weather service website
….Public Information Statement….
The
National Weather Service in Pittsburg has received numerous complaints
about our severe weather warnings breaking into local cable television
programming during severe weather events. The National Weather Service
has no control over the method that your local cable company chooses
to display our warnings. If you have complaints about the way our
warnings are displayed, you should contact your local cable company.
Again, the National Weather Service in Pittsburg is not responsible

SPOTTER
DO'S and
DON'TS
By Rusty Kapela, NWS Milwaukee/Sullivan 2/27/07
Do...attend spotter classes as much as possible.
Do...surf the web for additional information on spotting, severe
weather, etc. (including Storm Prediction Center)
Do...have a watch, pencil, note pad, cell phone, and colored Quick
Spotter Reference Guide with you when spotting
Do...make an effort to provide an accurate report - the time,
location, condition (what you experienced/saw), and location
Do...reference your severe weather report location to the
cultural/political center of the nearest
city/village, to the nearest 1/10 mile and one of the 16
compass points (stationary spotters)...such as...1.5 NNE Madison
Do...provide in your report what direction you are looking at
while viewing a rotating wall cloud, funnel cloud, or tornado,
since you can't accurately determine, in the heat of the battle,
how far away the wall cloud/funnel cloud/tornado is from your
position
Do...spot with a partner, especially if you are mobile - two heads
are better than one in this business!
Do...place the safety of you and your family first, your report is
second priority
Do...take a deep breath, try to remain calm, and get the job done
Do...utilize communication channels that have been set up for you
or your group, and follow proper format/procedures
Do...make sure the National Weather Service receives your report
via 911, or our 800 number, or ham frequencies, or E-Spotter
Do...be willing to freely share some of your severe weather
pictures with the NWS for educational purposes, on-line stories
(it's in the public domain)
Do...feel good about what you're doing as a spotter - you are just
as important as any other spotter!
Don't...assume you know everything there is to know about spotting
- keep an open mind - you'll learn something new every year
Don't...make it difficult for emergency response people (emergency
management, law enforcement, fire fighters, Red Cross, etc.) to do
their job - don't get in the way
Don't...just take pictures and video of a wall cloud or tornado
and forget to relay your spotter report
Don't...look at spotting as a game or procedure that will make you
look more important to your peers - keep a level head and just do
your best
Don't...look down at or ridicule another spotter for making a
mistake - you may make the next mistake - we all have - no one is
perfect
Don't...get upset at the National Weather Service if you don't see
your severe weather report appear on-line as a Local Storm Report
(LSR) or in a Public Information Statement (PNS), or in some "Top
News of the Day" article on the NWS's web page - we get hundreds
of reports from the 20 counties we service.
Don't...assume that you have a tornado just because you see
something that looks like a funnel cloud - you must see some
indication of ground-based, rotational effects (rotating
debris/dirt) underneath or very close to the funnel cloud in order
to classify it as a tornado - and there may be very little of any
funnel cloud
Don't...get caught up in the game of trying to be the first person
to call-in a tornado report - spotting is a game of being 100%
correct...it's not a game of being the first.
Don't...call-in or relay a report if you're not sure what you're
looking at - you must be 100% sure of what you're looking at -
accuracy is the highest priority, after your safety - We'd rather
have no report rather than a false report.
Don't...forget to give yourself a pat on the back - for your
volunteer, public safety efforts

The 2007
storm spotter training programs presented to the public and
emergency responders by the Milwaukee-Sullivan National Weather
Service have been added to the Milwaukee Area
Skywarn Association "Storm Spotter" webpage. The 'Basic' program
should be viewed by all beginners and trained spotters, while the
'Advanced' program is for those who have completed the basic
program and are seeking a more in-depth training. These Power
Point programs are excellent training or refresher materials, but
they are large files. Expect 3-4 minutes of download time even

NIGHTMARES FOR THE
EMERGENCY RESPONDER:
#1 TORNADO HITS TOWN BETWEEN RADAR
SCANS
On September 16, 2006, at 9:54
PM a quick-developing tornado struck about 20 miles Northwest of
Minneapolis in the town of Rogers MN. There were injuries, homes
damaged, and one fatality. A Weather Service investigation team
wanted to know why this storm was missed. Their findings suggest
(1) The first clear radar signatures occurred at the same time the
twister hit Rogers and (2) "the lack of real time storm reports"
(from spotters) affected the warning process.
Published in
November of 2006, this 24 page report in PDF is on-line at
http://www.nws.noaa.gov/om/assessments/
And second report from the NOAA
Inspector General is at:

(32 pages 1.66 Mb)
Rick Swierczynski, vice
president, Milwaukee Area Skywarn
Association (storm spotters), says "This event is a prime example
of the value and importance of a trained volunteer storm spotter."
He adds, "No community or individual is storm-proof, but we all
can be storm-ready. Individuals or businesses can establish a
Designated Weather Watcher, emergency managers can develop a local
storm spotter network and obtain official National Weather Service
StormReady status."

TORNADO ICONS REQUIRE CAUTION
A growing
number of internet web sites, radar software, and weather data
vendors are now showing radar maps that display a icon to indicate
a possible tornado. The display of this TVS icon (Tornado Vortex
Signature) can be misleading to the untrained emergency manager,
spotter, or weather enthusiast. Todd Shea of the La Crosse
Wisconsin National Weather Service says "Many spotters and net
controllers use private software that displays NWS Doppler Radar
data, including some of the algorithm output. One of the items
that often appear with stronger storms is the Tornado Vortex
Signature (or TVS) that indicates strong rotational wind shear at
a certain layer based on radar data.

Care should be used with this information. A TVS does not
automatically mean a tornado is there or likely. It indicates
there is rotation. It is often dangerous implying to a spotter
that a tornado is likely given the appearance of a TVS. There are
many factors that go into tornado detection and formation. The TVS
false-alarms quite a bit. You also have to have a good
understanding of the environment on that day and overall storm
structure."

HAM RADIO SKYWARN TRAINING NET
The next Milwaukee Area Skywarn
ham radio training net or 2008 has yet to be scheduled. These
training nets are broadcast the last Saturday of each month during
the warmer season on the 146.910 Mhz repeater. They are intended
to improve operator familiarity and efficiency in reporting severe
weather and also address issues on severe weather response in
general. The training net can be heard locally on any programmable
police scanner radio.
NEW TORNADO DAMAGE SCALE NOW IN EFFECT
Since February 2007 meteorologists and
wind engineers have been using a new "Enhanced Fujita"
scale for measuring the destructiveness of tornadoes. The new
format uses 8 levels of damage as determined by 28 different
indicators (strip mall, low rise building, school, metal/brick
building, etc.) Links, details, and documents at:
