The strong tornado that swept through Hattiesburg and Oak Grove in Lamar County, Mississippi, on Sunday has been rated an EF-4 with 170 mph winds, making it the first violent EF-4 tornado of 2013. The tornado hit Hattiesburg at 5:12 pm CST February 10, injuring 82 people and causing widespread damage over a 20-mile-long path. Miraculously, there were no deaths.The only other violent EF-4 tornado ever to hit Lamar County occurred on April 24, 1908, according to NWS Jackson.

The 2013 tornado season is off to an unusually busy start--a pattern we also saw last year. The January 29 - 30, 2013 tornado outbreak now has 56 confirmed tornadoes, including the only EF-3 tornado of the year, which hit Adairsville, GA, on January 30, killing one person. The outbreak is now ranked as the second largest January tornado outbreak since records began in 1950 (the largest: 128 tornadoes on January 21 - 22, 1999 .) NOAA's Storm Prediction Center logged twelve preliminary reports of tornadoes on Sunday, from Mississippi and Alabama. This brings the tally of preliminary tornado reports for the year to 100. On average, we've had just 72 preliminary tornado reports by February 10 during the previous seven years, 2005 - 2011.

Portlight receives $125,000 grant for New Jersey relief efforts
On September 14, 2008, the devastation wrought by Hurricane Ike on Texas and Louisiana moved members of the wunderground community to put into action their own impromptu relief effort. From this humble beginning has grown a disaster-relief charity I have been proud to support--Portlight.org. Portlight has stood up to support the needs of thousands of people affected by natural disasters since Hurricane Ike. After Hurricane Sandy, Portlight became a clearinghouse for local, state and federal agencies, including the FEMA Functional Needs Task Force--New Jersey, meeting the needs of people with disabilities. This week, Portlight announced that they had received a grant of $125,000 to continue helping in New Jersey in a big way. Congratulations, Portlight!


Figure 2. Vince Sciacca was in a horrific car accident a few years ago, which put him in a coma for nine months and left him with a severe brain injury. Shortly before Superstorm Sandy struck, and after much struggle, he had finally straightened out his equipment needs. The storm came along and destroyed everything. Portlight's project manager, Steve Major, delivered this power chair to Vince on February 2, and will be working with him to replace other equipment, as well.

Visit the Portlight.org. Portlight.org website to find out more or Portlight blog to learn more. Donations are always welcome!

The problem is not the car, the problem is the battery. Battery technology has basically not changed in 100 years, until there is better storage technology it will be a failure. Solar and wind have the same problem. Hopefully things will change in the storage area.

Why would he? As SteveDa1 wrote, of course more ice will be gained as years go by; there's less of it every summer. Arguing otherwise is disingenuous at best, or just outright stupid. Then again, that graph is from "Steve Goddard", so it should be taken with a mountain-sized grain of salt.

(It should be noted that ice that's being added to area and extent measurements now is thin and brittle first-year ice that will quickly breakup and melt after the maximum is reached sometime in the next two to six weeks. Look for new record minimums across the board come September.)

When the sea ice is reduced to zero, shortly.
Then any sea ice at all will be a 100% increase over what was not there before!
Maybe I'm wrong but anything that exsists must be a 100% more than Zero. No!
Lets get this into perspective. If the amount of sea ice that's frozen "temporarily" for a few months more or less melts, we have open seas.
The sea ice that never seemed to melt is HISTORY, at least and probably for the foreseeable future.
If your garden pond freezes over in January do you run out and scream,"Ice age coming! No you just say, "Nothing but a temporary cold snap, nothing to bother about!"
I personally would not be in the slightest bit bothered if the whole north Atlantic froze over, as the Hudson bay does, because when the big yellow eye gets over the equinox all is going to liquify.

This is for everyone... think of Manhattan as a giant (gridded) chessboard (the 16 pieces on it are the huge buildings)... streets go east-west and avenues go north-south. Manhattan is divided in three sections...upper, mid and lower.

Hey Mike, same here, most frequently click on via WU classic version! Loads faster, smoother on my old comp... Noticed same thing about the radars over past week, clicking on brought ya initially to the wide range 248 mi scale... however, just checked, it's set back to 124 mi close range, guess admin was adjusting / upgrading software, etc...

And pleased to say viewing our local KLIX radar, Houma area got all Mardi Gras parades in without the flooding rains that looked worrisome a few days ago... minor drzl or two, nothing to deter parade-goers / revelers! Yeah, got lucky / not needed on any account - already over 12" rainfall for the year here...

On another note - my old comp won't open the NHC's Sandy TCR pdf properly, just a blank page after a 4 minute download, lol... sigh, will wait a day or two for Google cache version to come out to read the specifics...

Cheers all!

So, another graph, but no comments on the many thoughtful responses (423, 427, 428, 432, 433, 434, & 435) to your Steve Goddard graph in #422? Wait--are you seeking to start an honest dialog, or are you just doing drive-by repetitions of talking points you found on contrarian websites? Because, frankly, if it's the latter, I've personally got better things to do...

Please do let us know. Thanks!


I had nothing to add. Greater sea ice loss during the summer results in greater ice gain during the winter.

I went to Manhattan today, all morning walking around Broadway, Grand Central ad south of Central Park, NYC

and Where is the snow???

In some spots you'll find some "ugly" snow sitting and slowly melting.
That picture below is near the intersection of Broadway and 6th Ave.

Report: "Sandy was USA's 2nd-costliest hurricane."

Heres the link:-

http://news.yahoo.com/report-sandy-usas-2nd-costl iest-hurricane-173626321.html

Good evening everybody from a tranquil southern Europe at 12/C in my area of activities.
They,( The northern Spanish lot,) have had up to 11 meters of snow, in some areas, that is about 36 feet and 'they' are raving,( as 'they' do, about a record.) I'm Sure Pedley will know one to play, which we can all pulse!
Meanwhile back on the launching pad, or my roof terrace, we have had about a quarter of an inch of rain and I have officially noted that the flies never died off this winter. In light of this we will more than lightly have another horrendously hot summer, which be enough to melt even the frozen dreams of the hardiest climate change de-nigh-ers.

Not to sound foolish as I don't know much about Artic sea ice but why the reduction in 2010-2012 compared to 2008/2009 if there should be an increased recovery each year?


I'm assuming it is because of the record-breaking (at the time) minimum extents in both 2007 and 2008.

You can make your own graph here.
