Weather radios now required for Indiana mobile homes
Posted by: Dr. Jeff Masters, 1:36 PM GMT en Abril 27, 2007 +4
Mobile homes sold in the state of Indiana after June 30 this year must come equipped with a weather radio capable of alerting residents of an approaching tornado, thanks to a law signed by Indiana governor Mitch Daniels this week. The legislation, dubbed "C.J.'s Law", was named after 2-year old C.J. Martin, who died in a F3 tornado that killed 25 people in southwestern Indiana on November 6, 2005. Twenty of the victims lived in the Eastbrook Mobile Home Park in Evansville. The storm hit at 2am, when many residents were asleep and didn't hear the tornado sirens. C.J.'s mother, Kathryn Martin, pushed lawmakers to adopt the bill, pointing out that weather radios with a tone alert system could have saved many lives in the mobile home park.

This type of law makes great sense for mobile homes sold in tornado alley--think of it as a companion to your smoke detector in the house. Mobile home residents make up just 7% of the U.S. population, but account for 40% of the deaths in tornadoes. However, there are a number of issues that may make the law ineffective. Firstly, what type of weather radio will be purchased? There are many poor quality units out there, prone to radio interference, and difficult to program (weather radios require the user to input a special SAME code, needed to issue tone alerts when a tornado warning is issued). Secondly, the NWS sends out weekly or monthly test alerts on weather radio--how many mobile home owners will simply turn off their weather radios because they are sick of hearing the regular tests? Or turn them off after a few false alarms wake them up in the middle of the night for tornadoes that appear on Doppler radar, but never touch down? Thirdly, once the residents of a mobile home park are awakened by an alert, where do they go? Indiana, like most states, has no law requiring mobile home parks to have a tornado shelter. However, there is now Federal money available for mobile home parks to construct tornado shelters, so the number of parks with shelters may increase in coming years. In summary, the law has the potential to save lives--but only if it is properly enacted.

Very interesting and a good idea. I feel better having mine. Not that you should totally rely on it but.... in the middle of night I'm hoping it will blast me if needed!

Nice report. Thank you Indiana for paving the way. I soon hope to see all states in the alley adopt this measure. And if opponents of this plan squabble about prices, then they desrve to have their insurance premiums skyrocket.

I guess the site was updating while I was trying to load. Big high all the way across the ATL, much like 2004 set up.

Also, the 8:05 discussion referes to a 1008 mb low over N Colombia near 10N94W. I guess that should read 74W.

Perhaps the low is responsible for the showers in the S Caribbean this morning

I have an older NOAA radio and turned the alarm function off since it would go off for all sorts of warnings, most of which were not in my immediate area. Can you select what type of warning on the newer radios?

9. chessrascal 2:02 PM GMT en Abril 27, 2007    
on the newer radios u can only program it to your specific area with SAME
10. RL3AO 2:07 PM GMT en Abril 27, 2007    
The blob is getting a little better organized today...even got a mention from the NHC in the discussion.
11. fredwx 2:08 PM GMT en Abril 27, 2007    
TO Chessrascal

what is "SAME"?

lol
14. chessrascal 2:13 PM GMT en Abril 27, 2007    
SAME i forget what it stands for but it is where u can program the alarm to only go off for your specific county insted of the whole broadcast area
15. chessrascal 2:13 PM GMT en Abril 27, 2007    
hope that helps some
17. chessrascal 2:14 PM GMT en Abril 27, 2007    
the winds are picking up on the Quickscat but i still dont see a circulation
18. chessrascal 2:15 PM GMT en Abril 27, 2007    
u can turn it on Tone Voice or Lights
19. RL3AO 2:16 PM GMT en Abril 27, 2007    
We can refer to it as Blob 01L

:)

Thank you Dr Masters. I would like to see it manditory for everyone living in storm prone areas to own one and have it part of your household insurance policy to have it. Too many lives are being lost because of little or no warning of impending and potentially dangerous weather. Its better to suffer through a false alarm than it is to lose a loved one. I would also like to see all churches, and public buildings have one as well. When new public facilities are being built, they should have some kind of shelter included in their plans especially in high danger zones.

The object of alert radios is to save lives, lets make sure we have a place of shelter to go to after the warning. Trailer parks are not set up as yet but that should be a priority of the owner of these parks to make sure there is a place of safety since living in trailers is becoming more and more common now especially in areas hit by Katrina.

If federal money is available, then by all means, do it and do it soon...Saving lives is the biggest priority one should consider.

Heres the infrared loop

http://www.ssd.noaa.gov/goes/east/carb/loop-avn.html

You can see the northern clouds are starting to get sheared from W to E.
25. chessrascal 2:18 PM GMT en Abril 27, 2007    
we will have to just wait and see if it can pull itself together but it does look a lot better than it did last evening then it was looking kind of sickly. :)

Shear is only 20-25K,thats not high!!

28. chessrascal 2:21 PM GMT en Abril 27, 2007    
i agree it is definetly getting a lot of shear

i doubt it will make it but it is still fun to watch
29. Levi32 2:22 PM GMT en Abril 27, 2007    
Actually, 25-30 knots of shear IS high. Too high for development of that blob. It's still just a sustained region of vertical motion, which the waters near Panama are known for generating. Only 1 out of every 20 of those actually develop, and somehow I don't think one of those is this one.

30. RL3AO 2:23 PM GMT en Abril 27, 2007    
Your right, it 25 knots shear (which is already high), but its drifting closer to the 35 knots area.

If only the blob could cross thru the Panama canal, then it would have a chance.
35. Drakoen 2:27 PM GMT en Abril 27, 2007    
lol the blob is firing back up and it looks gooid

36. Levi32 2:29 PM GMT en Abril 27, 2007    
That's true RL3AO it would have better chances in the Pacific. However when the waters near Panama (I forget the name of that bay) generate an area of convection it usually likes to hold on to its property lol.

Go west blob not north. You have a no shear zone 200 miles west!
41. Drakoen 2:33 PM GMT en Abril 27, 2007    
hmm. looks like the low is around columbia is it on or of shore?
oh yea and the shear needs to come down to at least 5-10 mph and that being extremely opimistic.

...A 1008 MB
LOW IS CENTERED OVER N COLOMBIA NEAR 10N94W. SCATTERED MODERATE
TO ISOLATED STRONG CONVECTION IS FROM 8N-11N BETWEEN 73W-80W.
ALSO...CENTRAL AMERICA FROM PANAMA TO GUATEMALA HAS AREAS OF
SCATTERED SHOWERS MOVING W WITH THE TRADEWINDS.

I live in Hillsborough County, FL and during the summer thunderstorm season that thing would be sounding off just too many times. At least now I could tune it just to my county which is better than the entire forecast area of Tampa Bay.

the low is over columbia that blob has even lesser of a chance. and you can see the dry air in the water vapor imagery showing the shear.

My Mom asked me that question. Where would I go? She is in a Mobile Home and thats what she asked me when I got her a Weather Radio. I told her get outside and get in the ditch! She is 81. You could imagine the look on her face.

the GFS model is predicting about 3 systems one in the pacific and two in the atlantic near the bahamas. the other one is near panama.

the gfs is also predicitng low shear values for the area that it has developing.
Member Since: Octubre 28, 2006 Posts: 57 Comments: 29010
50. Levi32 3:06 PM GMT en Abril 27, 2007    
Actually Drakoen, the GFS is forecasting higher shear than what it initialized with. In fact there's some initialization error, because the GFS has shear values currently at 10 knots or lower over the western Caribbean, which is obviously not the case.

I have to go now guys. Later everyone!
