The summer of 2012 was the 3rd hottest summer in U.S. history, said NOAA's National Climatic Data Center (NCDC) in today's State of the Climate report. June 2012 ranked as the 14th warmest June on record, August was the 16th warmest August on record, and July was the warmest month of any month in U.S. history, bringing the average summer temperature of the contiguous U.S. just 0.2°F shy of the hottest summer on record--the great Dust Bowl summer of 1936. Second place is held by 2011, which was just 0.1°F cooler than the summer of 1936. So far in 2012, we've had the warmest March on record, 3rd warmest April, 2nd warmest May, and warmest July. These remarkably warm months have helped push temperatures in the contiguous U.S. to the warmest on record for the year-to-date period of January - August. Temperatures this year in the U.S. have been so far above the previous record--a remarkable 1°F for the year-to-date period--that even if the remainder of 2012 ranks historically in the coldest one-third of September - Decembers on record, 2012 will beat out 1998 for the warmest year in history. Reliable weather records for the U.S. go back to 1895. The most recent 12-month period of September 2011 - August 2012 was the 4th warmest 12-month period in U.S. history, exceeded only by the 12-month periods ending in July, June, and May of this year.


Figure 1. The summer of 2012 was the warmest on record for Wyoming and Colorado, and ranked in the top-ten warmest on record for 22 other states. For the Contiguous U.S., it was the 3rd warmest summer since record keeping began in 1895. Image credit: NOAA's National Climatic Data Center (NCDC).


Figure 2. Year-to-date temperatures for the contiguous U.S. through August, compared to the previous record warmest years in U.S. history. Outcome scenarios based on persistence of temperature from September through December, the remaining five months of 2012, are shown. Even if the remainder of 2012 ranks historically in the coldest one-third of September - Decembers on record, 2012 will beat out 1998 for the warmest year in history. The January-August 2012 contiguous U.S. average temperature was 58.7°F, 4.0°F above average. The data for 2012 are preliminary. Image credit: NOAA/NCDC.

Most extreme January - August period on record
The year-to-date period was the most extreme in U.S. history, according to NOAA's U.S. Climate Extremes Index (CEI), which tracks the percentage area of the contiguous U.S. experiencing top-10% and bottom-10% extremes in temperature, precipitation, and drought. The CEI was 47% during the year-to-date January - August period. This is the highest value since CEI record-keeping began in 1910, and more than double the average value of 20%. Remarkably, 85% of the contiguous U.S. had maximum temperatures that were in the warmest 10% historically during the first eight months of 2012, and 75% of the U.S. of the U.S. had warm minimum temperatures in the top 10%. The percentage area of the U.S. experiencing top-10% drought conditions was 22%, which was the 11th greatest since 1910.


Figure 3. NOAA's U.S. Climate Extremes Index (CEI) for January - August shows that 2012 had the most extreme first eight months of the year on record, with 47% of the contiguous U.S. experiencing top-10% extreme weather.

Perfectly said , coudn't agree with you more. What happened in Homestead, show me that Florida wasn't prepared, most of those houses were so fragile to stand any hurricane, and never to a Cat 5, like Andrew. And of course, even in Puerto Rico we would be in trouble with a super Cat 5, of 180 mph winds, a rare event that only happens here in an average of every 100... years...


There was also, from what I can make out, a lot of building work that was done to Code "on paper" but never inspected before it was closed in - so Hurricane Straps and Clips missing etc. A bit like the tragic Mexico City earthquake of 1980/81(?) where many concrete buildings had been built without sufficient steel because Code Inspection was either inadequate or, dare I say - corruption crept in.
Having Code is not the sole weapon - you have to have Inspectors, who do their jobs without "grace and favour" and, legislation that has the strength and integrity to support them.

Nevertheless, most military structures (that require resilience, resistance to overshock etc)- especially structures such as Hardened Aircraft Shelters - are built to standards that civilian Codes could never hope to come close to - and they went in the face of Andrew.

That silver make-up was a killer sadly.



When the show girls from the old day used to be covered in it, they had to leave a small part of their back without it, so their skin could breath. But some actors had some severe allergies to those things.

Had to jump in on this one...
While here in Puerto Rico we do have many concrete buildings, most homes in fact are reinforced concrete with think steel rods... 180 mph is out of the question.
Sustained 180mph winds means probable gusts of 200+ mph, most of those nice "Valcor" windows are designed for 150mph, they well be ripped off.

Also, the truth is that most houses may be concrete and well built, but a lot of the aren't designed by engineers and are more "ad ons" that many people have made.

Even a good home would be in danger if a 180mph storm came. You'd sin of being foolish if you didn't realize that would be a bulldozer pushing against your home for hours on end... Not to mention what a branch flying through the air at that speed could do.

During Georges my Valcor "hurricane proof" windows didn't fly off, but even with the shutters geyser of water were shooting out of them and these windows were bending inwards greatly. It was terrifying to watch helplessly. They didn't break, and for all I know this is how they react and is what makes them survive (like a swaying building).


Either way, we are well prepared and used to these catastrophes. We do loose electricity for a while, being that it takes a while to reach some critical ruptures in remote places. But thankfully, Puerto Ricans and many in the Caribbean (with the sad exception of Haiti and occasionally the DR) do well with hurricanes.

Many people did loose their roof with Georges, but thankfully most loss was material and life was protected well. All in all, a Georges with the strength it hit Puerto Rico hitting somewhere like Florida usually leaves scenes of entire neighborhoods reduced to foundations of buildings.

To wrap it up... I do think places in the US need stricter building codes if they are going to allow so many people to live in dangerous areas, particularly storm surge prone coasts.

He had better have been a weatherman. He did not do so well in the rain and it served him well to know what the weather was going to be. It did not serve him well to become rusty with his weather forecasting.
