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.

I wouldn't say "most people don't care"; polling shows that a majority of people do indeed care. But that's not important; what's really important is that most scientists, especially climatologists, care--and most of them are increasingly worried. Of course, lay people are certainly free to cup their hands over their ears and shout, "Shut up and just deal with the weather!", but reasonable types know that ignoring a problem doesn't make it disappear.

Climate change is the greatest existential threat our civilization has ever faced. Wishing it away isn't going to work, I'm afraid... :\


Yea, but I've said this before, "most people" (working class), have too many other things to worry about. Are we able to pay the mortgage this month? How can I feed my kids and get the car new tires? Oh crap, we just hit our limit on that credit card. This is not only America, but most of the globe, not even taking into account some of the less fortunate and impoverished countries. Yea, climate change is on top of many scientists and some political agendas, thats what they do. Convince the rest of the population that something that isn't even proven yet, is more important than their day to day lives and making ends meet. Its a backseat topic to most.

Actually..Americans are most concerned with the economy and the the environment sits at the bottom of most polls..

"As President Obama prepares to deliver his State of the Union address, please tell me which one of the following issues you are most interested in hearing him address: the economy, the federal budget deficit, health care, gun policy, foreign policy, immigration, or the environment?"
They are going to start taxing us on Carbon..F'ers..Aussie is going to cry.

Yes.Sandy was a ugly wave so you wouldn't 'uve recongnized her from the start.However she merge with another disturbance in the carribean and started to gain more moisture and a more favorable environment.

I'm not sure what you mean by "cherry-picked"; that is just what the TCR states:

It's one of those "spring mornings" here.
You wake up, the road is wet, the sky is sunny, with scattered deep gray clouds around, and it's very humid.

Too bad winter is returning late this week.
Unless I see snowflakes.

My favorite blogger is back on :).Anyway Our chances of snow go up come Saturday night into Sunday.(Still not liking that as I have something to do.).The temps will be their so I'm thinking cold(temps in 30's) plus big coastal storm equals the fact that D.C could see our first major snow storm in a long while...Depends on the track though.

Just more pounding away at the agenda, Chuck. Every weather event used as an example for certain Folks to frantically log on and make their inconclusive points that the Earth is rapidly warming.

Keep talkin' that blah blah blah....


My main point remains unchanged. Every weather event, no matter how big or small, is now documented. 3 out of 4 people have some kind of cell phone or media device.

Link

Compare this to the 1980s when, lets see, maybe 1 out of 10 had access to a Zack Morris wireless phone. As great as social media is (Twitter, Facebook, etc.), it's a double edged sword. How many times in the last few years have we had to look at photos after a weather occurrence and dissect the real and fake ones? How many nor'easters were as strong as the one we saw last week, occurred in the 1318? Was there an EF-4 tornado near Hattiesburg, MS in 1145 AD? There may have been, but it wasn't documented. As far as I'm concerned, shut up and just deal with the weather. Prepare for it and quit trying to find consistencies between a "warming planet" and "extreme weather". Most people don't care, including myself. Too many mets out there think they know more than they really do. We're not impressed.

Of other note, Sandy achieved a secondary peak of 85kts, or a Category 2, the day of landfall.

if you go back to 19; they discuss how the forecast models had alot of troubles with the storm

A verification of NHC official track forecasts for Sandy is given in Table 10a. Official
forecast (OFCL) track errors were well below the mean official errors for the previous 5-yr
period at all time periods, and about 50% better than the long-term mean from 48 to 96 h. The
OCD5 (CLIPER) errors for this system were larger than the mean, suggesting these forecasts
were more difficult than normal, likely because of Sandy’s sinuous track, and as a consequence
the OFCL forecasts displayed a substantial amount of skill. A homogeneous comparison of the 20
official track errors with selected guidance models is given in Table 10b. The GFS ensemble
mean (AEMI), the Florida State Superensemble (FSSE) and the Atlantic Dynamical Model
Consensus (TVCA) all performed a bit better than the official forecast through 48 h. Although
the performance of the European Center for Medium-range Weather Forecasts (ECWMF) model
(EMXI) was unremarkable through 72 h, its days four and five forecasts were superior by far,
with extremely low errors. Most of the GFS-based guidance (including the HWFI and GHMI)
was less skillful, although the GHMI did outperform the official forecast at day 5. The ECMWF
model was one of the first to show the northwestward turn of Sandy at six and seven days (e.g.
Fig. 31b), even while most of the rest of the guidance showed the cyclone staying offshore of the
East Coast. Five days before landfall, the European ensemble guidance (Fig. 32) had a
significant number of members correctly showing the track of Sandy bending back toward the
United States, while the GFS ensemble members were mostly out to sea.
A verification of NHC official intensity forecasts for Sandy is given in Table 11a.
Official forecast intensity errors were near the mean official errors for the previous 5-yr period at
12 and 24 h, and much below the long-term mean from 36 to 120 h. The OCD5 (DecaySHIFOR) errors for this system were larger than the mean for Sandy except at 48 and 72 h. The
OFCL forecasts were quite skillful, although the forecasts had a bit of a low bias. The higher
OFCL errors in the 12-24 h time frame appear to be mostly due to a significant under-forecast of
the intensity of Sandy at landfall in Cuba. Only a few model forecasts even showed Sandy
reaching category 2 strength, with OFCL forecasts generally calling for a category 1 hurricane at
Cuban landfall. A homogeneous comparison of the official intensity errors with selected
guidance models is given in Table 11b. Overall, the official intensity forecasts were superior to
much of the model guidance throughout the period, with the greatest exception being at 120 h.
The HWRF was generally as good as or better than the official intensity forecasts, which is
perhaps fortuitous since it struggled with the track forecast. It is of note that the EMXI and GFSI
models beat the statistical-dynamical guidance (DSHP, LGEM) at 72-120 h, perhaps being able
to better forecast the wind field of Sandy due to its large size being relatively well resolved and
the importance of baroclinic influences with this cyclone.
