Forgive my ignorance, but what is an eye wall replacement?
I just filled up my gas tank, paid $2.81/gallon. Sucks to think how high gas prices are going to go up after this. However, I'd rather pay high gas prices than risk being in that area right now.
Watching Fox News, they showed people - including families - hanging out on the beach just watching the water. This includes toddles and other children running around, how stupid are these parents? That's child endangerment! If you want to sacrifice yourself, that's your own thing, but don't risk the kids.
Forgive my ignorance, but what is an eye wall replacement?
As of 7pm winds are down to 160 mph. Down 5 mph since 4pm.
what time is it supposed to land??
winds dropped to 160mph and the direction had changed to the north-northwest.
You are not alone. I would like to know too!
I'm more worried about where it lands.
CNN is showing a lot of information on Katrina.
NNW @11 mph, windspeed down to 160, temp 89.1, pressure up to 904 millibar
They just said its suppose to land within 12 hours. Its suppose to be a 4 or 5 when it lands.
Gov Blanco is on that WWL broadcast.
It is a cycle that all intense hurricanes usually go through. They can take anywhere from 4-18 hours and they usually involve the eye wall disintergrating and an outer eyewall moving in and taking its place.
While this happens the storm weakens and can lose around 30mph in wind speed.
The flipside is that if that is exactly what happens, after the cycle completes it can rapidly regain strength and get stronger.
It spent yesterday undergoing one of these cycles and spent last night and this morning blowing up and getting stronger.
But if the cycle can start now, it might hold up untill landfall and weaken the storm somewhat. It would still be a very strong storm, but its the best NO can hope for at this point.
During the eyewall replacement cycle, the hurricane is weakening (i.e. the maximum winds die off a bit and the central pressure goes up). Eventually the outer eyewall replaces the inner one completely and the storm can be the same intensity as it was previously or, in some cases, even stronger.
I just went and read the LJ journal of a friend of mine who used to live in NO and now lives in NJ. Anyway, her ex-husband still lives in NO and she has a son who goes and stays with him at times. So I just read her entry talking about how she just talked to her son on the phone and he's over there in NO, just playing outside, and he's "not supposed to come back until Thursday" she talks about how she and her friends screwed around during Hurricane Andrew and how nothing happened to them. Seriously it's like she is not even worried about it.. and her little boy is over there?!?! omg... stupid stupid stupid
Thanks for the info on the eye wall replacement
One day they'll figure out how to bomb a hurricane to break it up. Too bad that day isn't here.
The energy in that Hurricane is probably more than all of the world's nuclear arsenal. It gets it's fuel form that big h-bomb in the sky.
The thought that in 1900 and it still hasn't happened yet so don't look for it anytime soon. Like it or not, the Earth needs these kinds of things. Obviously not this violent. but it is still needed.
You seem to know a lot about hurricanes, do you just watch a lot of discovery channel or how did you learn all of this??
Thanks for the info, keep it coming.
They'll figure it out one day. Probably not soon, but one day.
mytze, I'm just a weather nerd. I just am really interested in this type of thing and have read up on it and try to follow along with what happens with them.
Not sure if this has been posted already, but anyways...

I wonder if they are using the Dyn-o-gel again??
Cool. Here's another question for you -- what's a millibar?? I'm hearing about it being 904 mb but don't know what that means.

States Prepare for Hurricane's Onslaught
The Associated Press
Sunday, August 28, 2005; 7:57 PM
GULFPORT, Miss. -- Mississippi's Gulf Coast rapidly emptied of even storm-hardened locals Sunday, leaving mostly deserted beaches, darkened casinos and boarded-up homes to face Hurricane Katrina.
"This is not a coastal storm," Gov. Haley Barbour warned. "We are talking about a 30 foot wall of water. Take this seriously."
Strong wind gusts already pounded coastal areas Sunday afternoon and conditions were expected to rapidly deteriorate. Evacuation orders were posted all along the coastal area.
Residents who remembered Hurricane Camille wanted no part of a repeat.
Camille, one of only three Category 5 hurricanes to hit the U.S. mainland since 1900, struck on the night of Aug. 17, 1969.
Winds of more than 200 mph flattened buildings and tossed boats across a beach-side highway that night. The tide surged to 24 feet, sending water over rooftops. In Mississippi alone, 131 people were killed.
"I expect maybe the frame of my building to be left," said Ron Roland, who owns a harbor shop at the Gulfport Marina. "I was here for Camille. It was unbelievable. It looked like an atom bomb went off around here."

PENSACOLA, Fla. (AP) _ Residents of several barrier islands in the western Florida Panhandle were urged to evacuate ahead of Hurricane Katrina.
Forecasters have warned that the Panhandle could be hit by wind gusts up to 55 mph, heavy rains and storm surge of 6 to 8 feet. The region has been hit by two hurricanes in less than a year.
"I'm just praying it stays on its current path and goes over to New Orleans. I feel for those people, but we've had enough in the last year," said Rusty Shaw, 25, who was getting ready to board up his home in Pensacola Beach, which was hit by Hurricane Ivan last year and Hurricane Dennis in July.
Katrina hit the southern tip of Florida on Thursday as a much weaker storm and was blamed for nine deaths. It left miles of streets and homes flooded and knocked out power to about 1.45 million customers.
Even though coastal areas in the Panhandle were under evacuation orders, traffic was heavy coming into the area from the west as Louisiana, Mississippi and Alabama residents tried to get away from Katrina.
___
MOBILE, Ala. (AP) _ Traffic moved at a crawl along Alabama highways Sunday as the rain started pelting evacuees fleeing east and north in anticipation of Hurricane Katrina.
By nightfall water began crossing the road at Fort Morgan and pooling beneath homes on stilts. Emergency officials warned the hurricane could bring historic flood levels to Mobile's downtown riverfront and leave bayou and beachfront roads well under water.
"Those being evacuated just need to make sure they reach higher ground," Gov. Bob Riley said.
The traffic was almost bumper to bumper as far north as Greenville by late afternoon on Interstate 65, and on Interstate 10 from the Mississippi line to the Florida border, the top speed was 25 mph in some area as residents fled. State Trooper Cpl. Spencer Collier anticipated the congestion would last through the night.
___
AUSTIN, Texas (AP) _ Gov. Rick Perry sent a 90-member urban search and rescue team to Louisiana to help out as the hurricane hits and in its aftermath.
Texas Task Force One, part of the 28-team national urban search and rescue system under the Federal Emergency Management Agency, is trained and equipped to locate and rescue people trapped by flooding and collapsed structures.
Up to 200 members of the Texas State Guard also could be sent to southeast and eastern Texas to set up and run shelters for evacuees fleeing Louisiana.
___
PITTSBURGH (AP) _ The remnants of Hurricane Katrina could also spell trouble for dams hundreds of miles away.
The Pennsylvania Department of Environmental Protection is monitoring dams closely, fearing Katrina and its remnants could waterlog the region as the storm moves over land.
"We are concerned going into every hurricane season, and we are particularly concerned this year because of the forecast for a larger than normal number of hurricanes," said Dennis ey, chief of the DEP's Division of Dam Safety.
Remnants of Hurricane Ivan caused massive flooding in western Pennsylvania last fall.
