re: Hurricane Isaias - Heading Towards the Central Gulf Coast

More importantly, it shows BR area at 66° at noon on Saturday.

Shut up bitch… the levees failed, period. The Industrial Canal levee failure is the main reason the 9th Ward and St Bernard flooded. They flew in large sandbags non-stop to plug the hole to stop to flooding. Don’t be a retard, some of us was there

100% brother

It's actually kinda amazing how little the AI models have moved in over a week. They were nearly a week ahead of the respected hurricane models. They pretty much stayed on an eastward track with the variation basically being moved a little more west. Considering the margin of error over a week ago that's kinda crazy.

Can we not, guys? Seriously, its fkn annoying having to sift through some kind of dumb multi page squabble when im trying to keep up with a hurricane.

Sorry. I got sick of that poster trying to rewrite history. I said what I said, I feel better now

I’ve totally ditched Storm2k on this storm.

OysterPoBoy just instantly vaporized 22 years of loyalty to that site.

TigerDroppings is clearly the #1 hurricane site.

I’ll suck your dick if we get a hurricane this week.

Offering that for a potential Cat 1 is crazy.

You offerin him anal if it gets to Cat 3?

The Lakefront Levees (They Mostly Held)

The massive earthen levees that run right along the shoreline of Lake Pontchartrain did not fail. Aside from some overtopping and minor erosion near Lakefront Airport on the eastern edge, the main lakefront wall successfully blocked the 10-to-14-foot storm surge from washing directly over the beach and into the lakefront neighborhoods. Neighborhoods right against the lake, like Lake Terrace, experienced very little direct flooding from the lakefront itself.

The Side-Door Canal Failures (Where the Water Entered)

Even though the lakefront didn't buckle, it acted as a massive reservoir. The storm surge raised the lake's water level drastically, which forced a catastrophic volume of water backward into the city's open outfall drainage canals.
Because there were no floodgates at the mouths of the canals in 2005, the lake's immense pressure pushed directly into the heart of the city, causing the infamous structural breaches:
• 17th Street Canal: Breached from the inside, drowning the Lakeview neighborhood and parts of Jefferson Parish.
• London Avenue Canal: Breached in two spots, flooding the Gentilly neighborhood.
• Industrial Canal: Overtopped and breached further east, devastating the Lower Ninth Ward.
Ultimately, the lakefront held the line, but the open canals acted like open doorways that allowed Lake Pontchartrain to pour straight into the city's low-lying bowl.
Would you like to see where the new post-Katrina permanent canal floodgates and pump stations were built to finally block Lake Pontchartrain's storm surges from entering these canals?

It seemed like it might be a tornado problem. Duke mentioned something about this earlier in the thread potentially spawning tornadoes.

Imagine it this way. You have a storm that's spinning counterclockwise like a spinning top. However, when it gets closer to the coast that spinning top os running into a treadmill thats going real fast in a perpendicular-ish fashion (oysterpoboy dont get excited).

Basically the spinning top gets split. The momentum (i.e. clouds rain wind) get rushed off in the direction of the treadmill...but in the process things start getting super spinny because of the mixing of two things with momentum and force (in non equal forces)
