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!

746 LargoFl: The Tampa Bay Seawater Desalination facility is a drought-proof, alternative water supply that provides up to 25 million gallons per day of drinking water to the region.

After drinking and cooking, that's about enough to let each person flush the toilet once per day... maybe 3times with the highest efficiency units.

How are the aquifers fairing? I know there is a massive aquifer system under Florida


They are polluted, and getting worse every day. Florida has more first magnitude springs than anywhere else in America. Almost all of them are suffering from reduced flow, and nitrogen pollution.

Actually the Gaylord hotel is located near Bowlings air force base and is 8 miles outside of D.C.It is located near Suitland M.D.I went to the little Mexicanplace there and I would agree.That tropical one with the citrus food was delicious.But I have a underage child with me and I'll be the only one driving.Hubby will be at home so I can see a disaster already.


I haven't been to that one, but it's likely a lot the same. Have fun! Hopefully the weather cooperates. When we went out, we were all walking, so all we had to worry about was finding our way back :)) I can see your worry with leaving the hubs at home... they just can't see all those dirty dishes, can they?

Quoting KEEPEROFTHEGATE:
hail in thunderstorms hail keeps rising and falling in ts until its to heavy then lands at the surface

ice pellets is rain that freezes into ice as it reaches surface where temps are at or below freezing
and freezing rain is rain that freezes once it lands on the surface thats at or below freezing
Very good KEEPER... In fact hail is pretty much like telling the age of trees by the rings..If a hailstone can be cut in half a person could actually tell how many time it had been thrown back up only to fall again. Each time makes another ring. Large hailstones may be throw back up many, many times due to strong turbulence caused by the thundersorm.... Ok, That's all my brain can handle at one sitting, How did I do??

I walk 4-6 miles a day as part of my commute (from the train station to the office and back). Forces me to get exercise, saves money and gas versus driving.

Is this the Gaylord near Oxen Hill, right across the Potomac from Alexandria? I stayed there for a business trip a couple of years ago, it's a very nice place :) We went in early fall so the weather was nice and we walked around to all the shops and had drinks at a little Mexican place down the street- don't tell your daughter, but they make killer margaritas!

So, now it looks like no snow or severe weather in GA for the next 2 weeks... I might cry.

And for the past month and a half, high temps have averaged Hi 50-70/Lo 30-50, and on the one day I go to run a 5k, its going to be 24 that morning, high 47 and windy.

I knew mother nature hated me, but I had no idea it was this bad.
