Weather radios now required for Indiana mobile homes
Posted by: Dr. Jeff Masters, Saat: 01:36 PM GMT Tarih: 27 Nisan 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.

yeah, miami needs a qb bad, but I think by them not drafting one early that signifies they are probably going to get green

Those bouys will probably not be put to use till mid july if the current trend continues.One main reason iam looking at is the strong tutt that is located over the central and eastern atlantic currently.Also i would like to add there is currently 40-50kt shear across most of eastern atalntic from the african coast to parts of the caribbean.I think the main factor here that might hold off any early development will be the tutt being well established as it is.Things can change but the way i see it things we might be shapeing up for a slow start.Adrian

Also quick note i dont see any progress towards La nina from looking at the sub-surface.Iam not 100% sold on any nina taking shape this summer.

More fantasy stuff from the GFS...Extremly long range and has to be taken with great caution.

One thing is true the 07 season is fast approaching.

Stormchaser,

I think you are under estimating. It predicted 4 TS last week. What's up with the GFS? It didn't seem to be as unreliable in past years as it has been lately?

Maybe that is just my imagination... I hope this is NOT the sign of a hectic hurricane season like 2005.

219. stormchasher Saat: 01:52 PM GMT Tarih: 29 Nisan 2007    
Dakster, yeah your right, it has been more than 4, also i REALLY dont think that anything will form because if you look at the wind shear maps there way to high for any development!! Another thing I have a funny felling about this season because the GFS never used to even predict tropical development!

Conditions are ripe for TS formation early into the season with the exception of the shear and the relative lack of moisture; we will have to see what happens with the shear in the next two weeks..

226. StoryOfTheCane Saat: 02:10 PM GMT Tarih: 29 Nisan 2007    
shear is pretty normal right now, we'd probably see 28 storms this season if shear was favorable right now as opposed to the 20+ we'll see regardless.
227. stormchasher Saat: 02:12 PM GMT Tarih: 29 Nisan 2007    
So StoryOfTheCane, whats your feeling on the H-season??

228. weathermanwannabe Saat: 02:13 PM GMT Tarih: 29 Nisan 2007    
Not sure what will happen in the long-term but I am pretty certain that we may see 1-2 tropical storms form before June 1st

My Predictions:

Right now I think we're looking at 19 storms, 13 hurricanes, 7 major hurricanes and 7 landfalls.

Gabrielle, Humberto, Jerry, Lorenzo, Melissa, Olga and Pablo are going to be our majors.
230. stormchasher Saat: 02:14 PM GMT Tarih: 29 Nisan 2007    
yeah that seems about right.

Last year we had two "tropical lows" before Alberto that rode up the east coast. We debated on here whether they merited being called depressions.

So we'll probably see the same thing in May/June. A few invests that could *possibly* be an early start to the season, but aren't.

That's what "normal years" are like. In 2004 and 2005, it seemed like anything with the potential to develop... did.

how many do you guys expect to see this year?
236. StoryOfTheCane Saat: 02:21 PM GMT Tarih: 29 Nisan 2007    
I think May 21st will be the first named system, second being June 2nd
237. stormchasher Saat: 02:22 PM GMT Tarih: 29 Nisan 2007    
Heres my forecast


1) 17-19 storms(not including depressions)
2) 9-10 Hurricanes 2-3 land falling
3) 4-6 Intense hurricanes ( cat 3- 4 )
4) 1-2 Cat 5 ( 2 If its a strong La Nina )

Becareful not to confuse shear tendency maps with wind shear.Shear tendency maps only indicate where shear is increasing or decreasing, they do not indicate the amount of shear across the overall tropics.Adrian

Actually the shear tendecy map has the shear in color with the key to that on the side. Solid yellow lines (increasing) & the dotted blue lines (decreasing) tells how much the shear has risen or fallen in the last 3 hours.

What you don't want to confuse with shear is the stearing currents map. (3rd down in Taz's maps post.) That has how fast the air is moving & direction for that particuclar layer of air.

Dry May= Higher chance of hurricane strike...... On several websites i read that dry mays here in South florida usually have hurricane strikes.... like in 04, 92 , and a couple others...... I thought this was very intresting ...

Ligthning10,

From your lips to god's ears on the slow season. Although, a "slow" season where I get hit with one hurricane, is still a bad year for me.

I see that as proenza states, we are learning, since Hurricane preparedness week is a little earlier now in May instead of June. I remember the hurricane preparedness fair in 2005. The first storm was threatening before the fair...

About South Florida, no rain in sight, drought, fires, and water restrictions... Blame the SFWMD (South Florida Water Management District). Apparently they decided last year to release billions of gallons of water out of Lake Okeechobe becuase it was supposed to be an acive season and they worried about flooding. I know hindsight is 20/20, but they did this in 2000/2001 the last round of water restrictions. The same forecast, the same thing happened. Granted, this is better than the Dikes failing along the Lake, but you'd hope they wouldn't drop the Lake like in 2000. I won't second guess the experts, but someone has to come up with a better way to do this. Instead of dike failure, we may lose our potable water supply which could be just as devastating as the Dike failures. Today's Miami Herald had a nice article about it.

So if the Hurricane Gods are listening, NO HURRICANES, but feel free to send a bunch of rain our way.
