U.S. experiences warmest 12-month period on record
Posted by: Dr. Jeff Masters, 6:09 PM GMT on May 08, 2012 +42
The past twelve months were the warmest twelve months in U.S. history, said NOAA's National Climatic Data Center (NCDC) on Tuesday, in their monthly "State of the Climate" report. Temperatures in the contiguous U.S. during May 2011 - April 2012 broke the previous record for warmest 12-month period, set November 1999 - October 2000, by 0.1°F. The past twelve months have featured America's 2nd warmest summer, 4th warmest winter, and warmest March on record. Twenty-two states were record warm for the 12-month period, and an additional nineteen states were top ten warm. NOAA said that the January - April 2012 period was also the warmest January - April period since record keeping began in 1895. The average temperature of 45.4°F during January - April 2012 was 5.4°F above the 20th century average for the period, and smashed the previous record set in 2006 by an unusually large margin--1.6°F.

Figure 2. The average temperature of 45.4°F during January - April 2012 was the warmest on record: 5.4°F above the 20th century average for the period, and was 1.6°F above the previous record set in 2006. January - April temperatures have been rising at about 1.9°F per century since 1895. Image credit: NOAA/NCDC.

April 2012: 3rd warmest on record
April 2012 was the third warmest April in the contiguous U.S. since record keeping began in 1895. Ten states had a top-ten warmest April, and no states were cooler than average. But what's really remarkable about April was that eight states--Illinois, Indiana, Kentucky, Michigan, Wisconsin, Ohio, Pennsylvania, and West Virginia--had average April temperatures cooler than their March temperatures, even though their April temperatures were still above the long-term average for the month. These statistics show just how remarkably warm March 2012 was. Most extreme was Illinois, where April 2012 temperatures ranked in the top 20% for warmest Aprils, yet were cooler than March 2012 temperatures.

Figure 4. NOAA's U.S. Climate Extremes Index (CEI) for January - April shows that 2012 had the most extreme weather on record.

Most extreme January - April on record
NOAA's U.S. Climate Extremes Index (CEI), an index that tracks the highest 10 percent and lowest 10 percent of extremes in temperature, precipitation, and drought, was 42% during the January-April period, over twice the average value, and the greatest on record. Remarkably, 82% of the contiguous U.S. had maximum temperatures that were in the warmest 10% historically, and 68% had warm minimum temperatures in the top 10%, with records going back to 1910. The previous records were 56% (2000) and 57% (1992) for maximum and minimum temperatures, respectively. The percentage area of the U.S. experiencing top-10% drought conditions during January - April was 19%, which was the 17th greatest since 1910. Extremes in precipitation as computed by the CEI were near average for the January - April period.

Posts like these are the reason i dont even bother with WU anymore.


I've just learned to truck through them, it's not so much that it's WU's fault - the general public's attention towards hurricane prediction is very limited and narrow and generally based on misinformation such as 'El Nino = Bust hurricane, all clear'

That attitude TWC takes too isn't helpful either 'Even though the models say a major system might be around in 6 days, go ahead and take that month cruise in the Caribbean in the middle of August!'

Thank WU for the ingore feature because you are now on mine.

BTW, great forecast by telling us to expect the rainy season in FL soon. That is like telling the folks in in October who live in Aspen to expect the snow season to start soon.

U.S. Senator sounds alarm about 'precarious' Fukushima situation, warns of imminent release of radiation

Wednesday, May 09, 2012
by Mike Adams,
Editor of NaturalNews.com


U.S. Senator Ron Wyden is, as far as Senators go, an honorable guy. I don't agree with all his politics, but I actually used to live in his district in Oregon when he was a congressman (1981 - 1996), and I remember him standing out as someone who genuinely seemed to care about the People.

To my knowledge, Sen. Wyden is the only U.S. Senator who has actually visited the Fukushima Daiichi nuclear power facility and warned the U.S. public about what he saw. And what did he see? A wrecked, half-collapsed building site littered with massive collections of nuclear fuel rods that now threaten the entire Northern hemisphere with a radiation apocalypse.

When Wyden returned to the USA following the visit, he immediately issued an urgent warning, now reprinted on his website. In the watered-down language of political correctness, the warning is still quite strong. As his website says: (http://www.wyden.senate.gov/news/press-releases/a fter-tour-of-fukushi...)

Wyden's principal concern is the relocation of spent fuel rods currently being stored in unsound structures immediately adjacent to the ocean. He strongly urged the Ambassador to accept international help to prevent dangerous nuclear material from being released into the environment.

He then went on to say, in his own words: (emphasis added)

"The scope of damage to the plants and to the surrounding area was far beyond what I expected and the scope of the challenges to the utility owner, the government of Japan, and to the people of the region are daunting. The precarious status of the Fukushima Daiichi nuclear units and the risk presented by the enormous inventory of radioactive materials and spent fuel in the event of further earthquake threats should be of concern to all and a focus of greater international support and assistance."

His website goes on to say something that should stun anyone who understands the threat of radioactive contamination of the environment:

"Wyden found that the facilities designed to house spent nuclear fuel and the reactors themselves were still in a state of disrepair and located in areas that would make them susceptible to further damage from future seismic events. The reactor buildings still contain large amounts of spent fuel -- making them a huge safety risk and the only protection from a future tsunami, Wyden observed, is a small, makeshift sea wall erected out of bags of rock."

Did you catch that last part? The only protection from a tsunami is a "makeshift sea wall erected out of bags or rock."

And to think, the fate of the world now depends on us all just "lucking out" and crossing our fingers in the hope that no earthquake or tsunami takes place before they clean up the Fukushima facility mess.

Which brings up the question: What exactly is being done to clean up the Fukushima facility mess?

In a word, nothing.

See now this is helpful. If you see a problem, let the others know that it is happening and identify the troll and point out who the victim is and others who aren't paying attention will see and not accidentally quote the troll.

The 12z GFS sends a 981mb cyclone into Florida in 360 hours, but develops it by Friday the 18th in a similar manner to a lot of our major October systems (Paula, Richard, Ida, Rina, ect)

Out in futureland, but I've never once seen a model predict a borderline Hurricane in May.

I don't think I've seen it, either.

That said... this is WAY out, and the GFS has always had a habit of developing stuff in the W Caribbean waaay out. I'm not saying it can't happen, but until more models can show this, its just one model. I find it interesting that the GFS ensemble is showing a generalized pressure drop, which definitely helps the operational's hypothesis.

Basically, lets wait until we are 6-7 days out before we jump on anything.

I agree the general quality of posting has greatly declined here on WU. Especially during hurricane season. During the season, the posts are basically 50% trolls, 10% actual questions, 10% actual answers, and 30% people calling the trolls out or feeding them.

The trolls names change constantly, but it is really the same dozen selfish, ignorant people (or so). The ones who post intelligently, and actually try to help have slowly dwindled over the past few years (now it is really only about 20-30 posters, you included).

I'll stay here trying to help as much as possible, but like you, I am becoming less a fan of the way the blog has changed.

I wouldn't write off a season before it has begun. Unless you can show some definitive correlation between El Nino Southern Oscillation patterns and storm tracks then its almost irrelevant in when it comes to determining whether or not a season will be a 'bust'.

I live in Bermuda (a 20 square mile island more than 500 miles away from the nearest landmass - an unlikely target right?) and I can attest that El Nino means little in terms of a bust or not. Each of the following Hurricanes brought at least tropical storm force winds to Bermuda: 2003 Hurricane Fabian, 2006 Hurricane Florence, 2009 Hurricane Bill, 2010 Hurricane Igor. Yet in 2005 we were spared tropical storm force winds from all 15 hurricanes (despite a few close calls from tropical storms Franklin, Harvey, and Hurricane Nate).

Each of these years had anomalies on either side of the El Nino spectrum and the "it only takes one" broken record continues to play.

Why should you care?

Actually, I care because I have friends in FL who could be impacted. I also care because I have an interest in tropical weather. I also have a bit of a pet peeve when people jump on one model's very long range output, and use it as gospel... when it is still more than a week out. It is kinda like planning a vacation when you don't even know when or where you are going.
