Fourth warmest May on record

The tropical Atlantic remains quiet. None of the computer models are showing any tropical development over the next week. The best chance of a new threat area to watch may not occur until July 1, when a strong cold front pushes off the U.S. East Coast.

The Middle East will see their second tropical cyclone of the month on Tuesday. Tropical Cyclone 3B crossed India, killing at least 140, and re-formed in the Arabian Sea, and is poised to hit Iran or Pakistan tomorrow. The View From the Surface blog is following this storm. We may looking at hundreds of years since the last time the Middle East was hit by two tropical cyclones in the same month. Tropical Cyclone Gonu pounded Oman and Iran earlier this month.

Fourth Warmest May on record
May 2007 was the fourth warmest May for the globe on record, and the period January - May of 2007 was tied with 1998 for the warmest such period ever, according to statistics released by the National Climatic Data Center. The global average temperature for May was +0.53�C (+0.95�F) above the 20th century mean. Over land, May global temperatures were the warmest ever measured, the second straight month that has happened. Ocean temperatures were a bit cooler (ninth warmest on record), thanks to the cooling associated with the disappearance of the winter El Ni�o event. The global temperature record goes back 128 years.

May temperatures were particularly warm across Russia. Moscow recorded its highest May temperature since record keeping began 128 years ago--32.9�C (91.2�F). The heat forced Russia's energy administrator to restrict the use of non-residential energy for the first time in summer. In India, a heat wave during mid-May produced temperatures as high as 45-50�C (113-122�F) resulting in at least 128 fatalities. Dr. Ricky Rood's Climate Change blog has more on the India heat wave. Although record heat was more prevalent across the globe, Argentina experienced its coldest May in twenty years, and at least 23 fatalities were reported as a result of cold weather during the last week of May.

11th warmest May on record in the U.S.
In the U.S., May 2007 ranked as the 11th warmest since record keeping began in 1895. The period January through May was the 20th warmest such period on record. Spring (March - May) was 5th warmest on record in the continental U.S. The past six months (Dec-May) were the driest on record for the Southeast U.S. Portions of Alabama, Mississippi, and Tennessee are experiencing exceptional drought. However, the drought has eased some since late May over the Florida Peninsula.

Sea ice extent
Sea ice extent in the Arctic for May was the third lowest on record, a modest recovery from the lowest ever sea ice coverage observed in April. Arctic sea ice coverage in May has declined by about 8% since measurements began in 1979 (Figure 2).

I'll have a new blog on Tuesday.

Yea the back end was actually worse because when it moved into the Atlantic, it stalled a little bit and strengthened so those back end feeder bands were Cat1 and here I thought the worst was over! We saw water being lifted out of our pool like a scoop!

That is the sobering thought that I think about often during the season. The elderly population in Pinnelas county is staggering.

I actually had surgery the week before Jeanne. I never thought I would be standing in Home Depot 5 days later preparing for another storm.

Frances was the storm that psychologically got into our heads. It NEVER ENDED! Over 20 hrs of those conditions can really wear on you


The thing that was awful for us, was deciding if we were going to stay or leave for the second one Jeanne, we just could not believe that that hurricane did the loop de loop and headed back to us. It was really a mind boggling thing. We have lots of senior citizens and they were just wore out after that season.

How big was that eye? It seems everyone in Palm Beach and Martin was in it. I know we were cause I just waited for the reprive..When it came we walked the dogs cause it was a long haul for them. The backside wasn't that bad..not like Wilma where the 2nd half was just nasty! We lost our linai screen and the kids swing set in Frances..Jeanne finished them off for good.

I hope it isn't a sign of things to come Adrian. We have had a ton of very healthy strong waves already this season well before they can form, which is why they have died shortly after seperating from the ITCZ.

Vero Beach - about 10 miles on the north side of the eye for Frances and about 6 miles north side of the eye for Jeanne. Boatloads of rain from Frances, but Jeanne did the worst in wind damage.

About 5 mi N of Biloxi, wind rocking large heavy camper and thundering like the devil.
Hope this is the worst of it, they almost opened the clubhouse (storm shelter) last night also, no warnings now.

Gator..Where are you located? Fran and Jeanne were just so inconvenient..Frances just pounded us forever! The cold showers were hard..My youngest was 1 at the time and he was covered in a heat rash that was just aweful.It was hard to get him in the bath. We have gas but to boil all those pots and take them up the stairs was no fun!Sleeping was rough too.. I must admit I was one ill prepared person for the first one. I would have never imagined being out of power for 10 days.Thank god I did have enough food.The county was not prepared either. It was a mess.
