More Rain...More Flooding?

With over a foot of rainfall (13.50")in the 1st 12 days, the ground is totally saturated and any more rain will quickly runoff creating more street flooding. NWS is predicting the possibility of 1-3" beginning early on Monday into late Tuesday. Hopefully it'll be spread over many hours allowing the pumps to keep up. The rest of the week will see several cold fronts with the potential for freezing temperatures by the ean of the week.

Caveman believes the Associated Press is an unbias news reporting organization. Can't argue with someone who believes that. If the AP says it, it's the truth. Yea right. Like the NY Times & Washington Post...truly unbiased newspapers! Give me a break!

Saturday looked like water, water everywhere. We were stranded in our car
in the u-turn on West Metairie near Cleary. It came up so fast ... hope we
get to dry out a little before the
other systems get here.

Thanks for keeping us updated Bob!

I voted yes for the snow this year,,,

It is the wettest December on record with over 13.50 inches of rain falling in the first 14 days of the month. You can thank a Strong El Nino which has put us in an active stormy pattern. When so much rain falls in a short period of time it causes problems, in this case the ground is saturated to the point to where it can't absorb any more water and even 1 inch of rain can cause big problems.

This morning expect the dense sea fog to persist until ~8am-10am. Later this morning an upper level disturbance will begin to move into the area. This will push the Warm Front a little northward and this should also end the fog, however, this is also when the rain is expected to develop. This is because the upper level winds will increase causing lift at the surface; this aids the development of showers. The rain should start around noon and gradually increase in coverage and intensity as the Shortwave moves in. Highs today are expected to jump to near 72 degrees, before the rain starts. The rain is expected to continue until Tuesday afternoon, but there will be some occasional breaks. The rain is expected top become heavy at times with widespread totals being in the 1-3 inch range, although, I think training will be a possibility and if anyone gets stuck under training cells rainfall totals could reach 5-6 inches. If that amount of rain falls, even on the lower side of the totals, it will cause problems because the soil is extremely saturated and the water will have nowhere to go but the lowest point and just simply collect, that's what happened to us Saturday Night. This upcoming heavy rainfall threat has triggered the issuance of Flash Flood Watches; a Flash Flood Watch means that Flash Flooding conditions are forecasted to occur in the next 48 hours.

Wednesday Morning a strong cold front will push through the area taking all the moisture and nastiness with it and bringing in a much cooler and drier air-mass. Highs Wednesday and Thursday will be near 60F but it will feel chilly with winds out of the North at 15+mph. The Northshore might even see another light Freeze Wednesday and Thursday Night. The Southshore will drop into the 40's both nights.

Beyond that, the models go into serious disagreement. One model keeps us Dry and begins moderating temperatures by the weekend. The other models advect another shortwave into the area on Friday causing another heavy rainfall event and then it dives a strong trough into the US for the weekend advecting a significantly colder air-mass.

Bob,

Caveman also sees "no harm, no foul" in the climategate e-mail scandal. Of course the glowarmies would say there is no change in their position. What else did you expect them to say?

If the "science" behind climate change (AGW) is SO solid, then why does ANYONE need to fudge figures??
I don't care how many proponents there are to AGW, these proponents RELIED on data by the ONES guilty in the scandal. Many, many, many folks have relied on data produced by Michael Mann and his buddies. This is NOT just incidental error like you folks want us to believe.

Hey Caveman, does "credibility" mean anything to you? Does integrity mean anything to you? How do you expect folks to believe you when there is deceit?

I just heard that there are around three times more AGW skeptics than there were just a few years ago. I wonder why?

You guys are embarrassed and are just trying to wiggle out of the precarious situation you put yourselves in. Hopefully, enough stink is raised to stop this nonsense in Copenhagen.

I just thought that I would let you know that your comments are both smart and hilarious at the same time.

On a watery note of weather...

With all the rain on Saturday evening my pool was overfilled with water. At halftime during the Saints game I decided to drain it thru the waste cycle.

With the Saints game being another coronary game, I naturally forgot all about the pool. When my brain finally clicked, the pool pump was sucking air as I drained it way too much.

Luckily I have a lot next door which I drained the water so it wasn't all in my back yard. I turned the pump off and based on weather reports I was going to wait till it rained again to fill the pool back up.

As I type, I am here to happily report that Channel 8 weather reports have served me well as the rain is filling my pool right back up and I didn't have to use the hose!!!

Now where else in the world can you get a cardiovascular workout by just sitting in your chair watching a Saints Game!!!

More heavy rain is forecasted for today and it will continue to be a threat until the Cold Front over North Louisiana reaches us this evening. The majority of the rainfall is along a stalled boundary that is stalled across the area that is providing a focus for heavy rainfall development. As a result, 3-6 inches of rain fell across the Southshore over night due to training of heavy cells. Another 2-4 inches of rain is possible today and continued a continued Flooding Threat is likely.

Tonight, a strong cold front will push through the area taking all the moisture and nastiness with it and bringing in a much cooler and drier air-mass. Highs tomorrow and Thursday will be in the 50's and it will feel chilly with winds out of the North at 15+mph. The Northshore might even see another light Freeze Wednesday and Thursday Night. The Southshore will drop into the 40's both nights.

On Friday, another Surface Low will develop in the Gulf and pass off our coast. The Track of the Surface Low will greatly determine how much rainfall we will get Friday. The further south it tracks the less rain we get the further north it tracks the more rain we get. Saturday and Sunday looks dry and cold with Highs in the Low-50's. This is because of a deep long-wave trough that will dig into the Lower 48. A Hard Freeze on the Northshore, and a light Freeze on the Southshore looks likely on Saturday Night.

Onlyreal,

Thank you, I think that's a compliment. I hope what you mean by "hilarious" is the fact that these AGW folks believe they can keep "buffaloing" intelligent folks. But, in following the Copenhagen comedy show, featuring Al Gore with his Walmart laser pointer and Powerpoint presentation, it's becoming more clear that they have no intention of succumbing. These folks seem to have the upper hand, yet they use bullying demonstrations around the conference. These are the "well-meaning" green environmentalists being unruly and disruptive. Many have already been arrested around Copenhagen. But you won't be hearing much of this news on NBC Nightly News or on MSNBC.

By the way, Onlyreal, I find you extremely knowledgeable in meteorology for such a young chap. Keep it up. Your interest and perseverance may wind you up in the Little Fella's shoes one day. But ya gotta work on your stage presence to match him.

I had to post this after my 5 year old son, Ryan, ask us two times. He, first, asked me to you last night to call you & see if you could do anything about the lightening & thunder. And, then, this morning on his way to school he looked at his dad & said, "Can you call Bob Breck? Mom didn't do it!"

Of course it was a compliment, Craig. And thanks for your compliment too.

SYDNEY – Australian authorities Friday issued a shipping alert over a gigantic iceberg that is gradually approaching the country's southwest coast.

The Bureau of Meteorology said the once-in-a-century cliff of ice, which dislodged from Antarctica about a decade ago before drifting north, was being monitored using satellites.

"Mariners are advised that at 1200 GMT on December 9, an iceberg approximately 1,700 kilometres (1,054 miles) south-southwest of the West Australian coast was observed," it said, giving the iceberg's coordinates.

"The iceberg is 140 square kilometres in area — 19 kilometres long by eight kilometres wide."

Experts believe the iceberg — known as B17B — is likely to break up as it enters warmer waters nearer Australia, creating hundreds of smaller icebergs in a hazard to passing ships.

"It's still 1,700 kilometres away, so it's quite a long way away, it's not really on our doorstep yet but it's been heading steadily towards us," glaciologist Neal Young said Thursday.

Young earlier told AFP that an iceberg of that size had probably not been seen in the area since the days when 19th century clipper sailing ships plied the trade route between Britain and Australia.

The iceberg has been floating around Antarctica since shearing off the icey continent but had lately begun heading north because of ocean currents and weather conditions.

Its discovery comes after two other large icebergs were spotted further east, off Australia's Macquarie Island, followed by more than 100 smaller chunks heading towards New Zealand.

Young described the icebergs as uncommon, but said they could become more frequent if sea temperatures rise through global warming.

Funny how those that don't believe the earth is warming but rather cooling never mention stuff like this that is taking place.
