I agree with this for the most part, however, if my family lives below a dam I am going to act when I hear "Paul Reverie" ride down my street. I am not going to wait for everyone to brief each other so they can get a nice canned warning out to the press. The guy may have to change his story later, but his intentions of trying to save lives should not be taken lightly or demonized. Panic or not.
You forgot rita and wilma.
From the same Facebook page:
Pam Duncan: Homeland Security said it had been Breeched on TV !!! He said GET OUT NOW !!!
This is what I mean by spreading panic.

NWS is issuing flash flood emergency warnings.
"Here are the two season's to-date tale of the tape:"
Reading is a good thing.
I am lake property, but not lakefront. Our lake is always lowered prior to a hurricane or TS. I wonder if they did that with this lake prior to Isaac?
Until about 20 miles downstream, there is mostly pasture and farmland threatened. The total flow, even if the dam completely failed, which it hasn't, and it's not likely, would be about a 6 foot rise. Controlled releases will cause more on the order of a 1 foot rise. This will hardly be noticed in already flood swollen rivers. It's one thing for a politician to comment on a potential dam failure, it's quite another to say you have 90 minutes to get out or you're all going to die. People also die when engaged in panicked evacuations that have no basis in fact from traffic accidents.
Mississippi is breaching the lake to lessen the the threat so.
BTW, both of these areas have historically been safe.
Cat-1? Wow!
Frigate birds nest off Cedar Key Florida. I was amazed to see them there a couple years ago.
It's not a lake dam that can be opened and closed. Most of our state park lakes are creek fed and have and overflow culvert on the downstream end.
When rains like this occur, the culvert cannot release the water as fast as it's coming in.... creating the problems mentioned.
Correct. This dam had a much bigger failure in 1983 and no lives were lost. As I have already posted, it's pasture and crop land that would be flooded in the event of an uncontrolled failure. The people who live along the river are aware of the dangers from this dam.
:)
Add: Ps LOL. New blog. Ho hum... Bye bye)
Taco :o(
What?
6 ft puts the river at ~17 ft. That's a catastrophic and historic flood with the "already swollen" river, which would then overflow all over the place. I live by a river that has had huge floods. When they're "already swollen," another foot or two can turn it into total catastrophe. You notice a foot when it's already too high, because it's over the banks and filling your friggin' neighborhood.
That 20 miles of farm is about 90 min warning for larger communities with that much water coming downstream, and the farmers ain't no worry, either.
Jindal confirmed that evac along the river in LA is mandatory and that the dam is not breached but is damaged, damage still being assessed.
"Don't panic" is always a good message, but one of the things in my experience that _feeds panic_ is feeling like the authorities are feeding you "nothing to see here" BS. I've lived that.
Done arguing over it. Folks close in below the dam should get out IMO regardless, because if it does fully breach, they won't have a whole lot of warning. And I hope everybody down there is safe and attentive, neither panicking nor thinking it's all just dandy no worries.
From the article:
"Mayor Whitney Rawlings of McComb, Miss., told CBS News that there was a "50-50 chance" of the dam failing at Lake Tangipahoa in Mississippi's Percy Quinn State Park, just south of McComb. He urged people south of the dam to evacuate.
"People need to be moving," Rawlings told CBS News.
In Louisiana, Tangipahoa Parish President Gordon Burgess issued an emergency alert warning of an "imminent failure" at the dam. Burgess said between 50,000-60,000 people had 90 minutes to evacuate, CBS New Orleans affiliate WWL-TV reports."
Again, politicians should let EMA officials release official information. Still, you can see the difference in the statement between the McComb mayor and Parish President Gordie calling WWL directly and issuing his "90 minute" evacuation order. I'm really hoping people here will stick to sources like the local and state EMA's, as well as the NWS, and not take every word from a TV station, a politician, or social media as gospel.
Agreed, although, again, the dam has not, and is not likey, to catastrophically fail, so the 6 foot number is the worst case. Still, there is plenty of time to evacuate if it's needed. My heartburn is one politician calling a TV station and issuing his own 90 minute evacuation order. It wasn't needed, spread panic, and made rumor control that much more difficult.
My thoughts haven't changed at all. It was a Cat One storm. Flooding occurs in a Cat One Storm. Flooding occurs at a greater rate when you build homes below sea level.
You guys are all still upset you didn't get the Cat 4 or 5 monster you wished for. When you were told for days it would never be greater than a weak Cat 2. You are probably still upset it didn't increase to a Cat 2 before landing like you dreamed of.
This blog is filled with Chicken Littles.
That's for sure. More storms are about to hit the Mobile area, and the rainband is now spreading into central AL, with us being under a tornado watch. There's also a tertiary rainband developing off the Gulf and over the Panhandle, into south and central AL. Even as Isaac weakens, he's still spreading some mean weather several hundred miles to the east.
well said
You are assuming that everyone has access to all of the different groups you have listed. When anything of this type occurs, you should err on the side of caution. It is also not smart to assume that the majority has the ability to filter out the messages across 5 different mediums.
