PRELIMINARY DATA...

EVENT TYPE: EF-4 ESTIMATED PEAK WINDS (MPH): UP TO 180

INJURIES/FATALITIES: NUMEROUS INJURIES/UNKNOWN.

EVENT START LOCATION AND TIME: 33.6792/-86.5699 AT 623 PM

EVENT END LOCATION AND TIME: 34.0661/-85.420 AT 747 PM (AT GEORGIA STATE LINE)

DAMAGE PATH LENGTH (IN MILES): 72 MILES

DAMAGE WIDTH: UP TO 1.25 MILES

NOTE: CONTINUED INTO GEORGIA NATIONAL WEATHER SERVICE METEOROLOGISTS SURVEYED THE DAMAGE PATH FROM EASTERN JEFFERSON COUNTY NORTHEAST TO CHEROKEE COUNTY.

IT HAS BEEN DETERMINED THAT THE DAMAGE WAS CONSISTENT WITH A STRONG TORNADO. THE TORNADO TOUCHED DOWN NEAR ARGO...BETWEEN DEERFOOT PARKWAY AND ADVENT ROAD...JUST NORTH OF INTERSTATE 59. THE TORNADO THEN MOVED EAST ACROSS THE INTERSTATE INTO ST. CLAIR COUNTY. THE TORNADO CAUSED EF-0 TO EF-1 DAMAGE AS IT TRACKED NEAR MARGARET AND NORTH OF ODENVILLE. JUST NORTHEAST OF ODENVILLE...THE TORNADO STRENGTHENED AND WIDENED CONSIDERABLY. THE TORNADO THEN MOVED EAST-NORTHEAST ALONG COUNTY ROAD 22...THROUGH SHOAL CREEK. DAMAGE ALL ALONG CR-22 WAS EXTENSIVE. SEVERAL HOMES HAD ALMOST ALL WALLS BLOWN OUT...AND ONE ROUGHLY 40 YEAR OLD HOME WAS COMPLETELY LEVELED. THE PATH CONTINUED EAST-NORTHEAST ACROSS NEELY HENRY LAKE INTO CALHOUN COUNTY. THE GREATEST AMOUNT OF DAMAGE WAS DONE ON THE EASTERN SHORES OF THE LAKE...JUST NORTH OF OHATCHEE. IN THIS AREA NUMEROUS HOMES AND MOBILE HOMES WERE COMPLETELY LEVELED...INDICATIVE OF A STRONG TORNADO. AT LEAST ONE WELL BUILT HOME WAS NEARLY SWEPT CLEAN OF EVERYTHING ABOVE ITS BASEMENT...SAVE FOR A FEW ITEMS OF FURNITURE. WINDS HERE WERE LIKELY UP TO 180 MPH. THE DAMAGE PATH AT THIS POINT REACHED ITS WIDEST... AROUND 1.25 MILES. THE TORNADO CONTINUED TO CAUSE EXTENSIVE DAMAGE ON AN EAST-NORTHEAST PATH ACROSS NORTHERN CALHOUN COUNTY...JUST SOUTH OF THE ETOWAH COUNTY LINE. ALL HOMES IN ITS PATH RECEIVED SIGNIFICANT DAMAGE AND MANY WERE COMPLETELY DESTROYED. A SMALL CHURCH ON ROCKY HOLLOW ROAD NEAR THE WEBSTER CHAPEL COMMUNITY WAS COMPLETELY LEVELED. THE TORNADO BRIEFLY WENT THROUGH SOUTHEAST ETOWAH COUNTY SOUTHEAST OF REAVES...CLIPPED A SMALL PORTION OF CALHOUN COUNTY ONE LAST TIME...THEN MOVED INTO CHEROKEE COUNTY. THERE IT DAMAGED NUMEROUS MORE HOMES AND MOBILE HOMES AS IT MOVED EAST-NORTHEASTWARD. THE TORNADO APPEARED TO WEAKEN BRIEFLY AS IT MOVED THROUGH FROG MOUNTAIN...BUT THEN IT WIDENED AND STRENGTHENED ONCE AGAIN BEFORE IT REACHED COUNTY ROAD 45 NORTH OF ROCK RUN. ON COUNTY ROAD 29 SOUTH OF FORNEY...AN APPARENTLY WELL BUILT FRAME HOME WAS COMPLETELY LEVELED TO THE GROUND BY WINDS THAT MAY HAVE EXCEEDED 150 MPH. THE TORNADO THEN MOVED INTO GEORGIA AT COUNTY ROAD 28. ALONG THE PATH...HUNDREDS OF STRUCTURES WERE DAMAGED AND DESTROYED...AND MANY THOUSANDS OF TREES WERE UPROOTED...SNAPPED...AND REDUCED TO SPIKED STUMPS.

They did upgrade it WxMann. That was the St. Clair county tornado. I thought it was finalized as an EF3.

Makes me wonder if they will look at Tuscaloosa/Birmingham tornado more too.

they must have poor construction standards... seeing the aerial views of entire neighborhoods obliterated made me think, "this is definitely an EF5"

I suspect that they are bringing in additional experts to survey the damage... thus lack of information/updates in the PNS thus far. Also I suspect that the consensus of other experts overruled the first in the assessment of the Ohatchee tornado.

I'd have to imagine this is the case.

As it has been said, trying to compare outbreaks to each other is tough, and imo silly to do because there's so many different factors that go into it.

I think the main thing this will be remembered for is that it took an amount of lives that many thought could never, would never be possible in the modern age.

Yes but houses were only only shredded into 5000 pieces each. They need to be in 5500 or more for an EF5.

Um, you are wrong. Look at the times/locations on each of those. There were three separate EF4s in Jackson County.

Yup.

* EVENT DATE: 04/27/11

* EVENT TIME: 4:01 PM TO 4:36 PM CDT

* ESTIMATED PEAK WIND: 190 MPH

Jackson Co Tornado #2 posted in my earlier post.

The first tornado was produced by the Cullman-Arab supercell that initiated in Walker Co in the early aftn hours in the free warm sector. The second tornado was produced on a supercell that developed behind the first supercell and intensified quickly around 22Z, right before the HTX radar went down.

A VIOLENT LONG TRACK TORNADO BEGAN ITS LIFE ABOUT 3 MILES NORTHEAST

OF SECTION AS AN EF-0 TO EF-1 TORNADO WITH PEAK WIND SPEEDS OF 70 TO

90 MPH SNAPPING OR UPROOTING SEVERAL SOFT AND HARDWOOD TREES. THE

TORNADO RAPIDLY INTENSIFIED TO HIGH END EF-3 TO LOW END EF-4

170 MPH AND A PATH WIDTH OF 1/2 TO 3/4 MILE AS IT ROARED INTO AREAS

NORTHEAST OF PISGAH AND NORTH OF ROSALIE. RESIDENTS INTERVIEWED

REMARKED THAT THIS TORNADO WAS MULTI-VORTEX WITH UP TO THREE

TORNADOES MERGING INTO ONE VERY LARGE TORNADO. THERE WAS SOME

EVIDENCE OF THIS IN THE DAMAGE SWATH...BUT AN AERIAL SURVEY MAY

PROVE MORE TELLING.

THIS TORNADO SWARMED SEVERAL MOBILE HOMES AND BLOCK FOUNDATION HOMES

IN ITS PATH...AND SNAPPED OR UPROOTED THOUSANDS OF TREES. NUMEROUS

TREES WERE DEBARKED IN THE PROCESS. THE TORNADO LEVELED AT LEAST TWO

MOBILE HOMES AND SWEPT THEIR REMAINS HUNDREDS OF YARDS DOWNWIND.

CHURCH ROOF WAS HEAVILY DAMAGED. SEVERAL FARMS WERE ALSO

AFFECTED...WITH BARNS AND CHICKEN HOUSES HEAVILY DAMAGED OR

DESTROYED.

AS THE TORNADO CONTINUED ITS TRACK...IT INTENSIFIED EVEN FURTHER TO A

HIGH END EF-4 INTENSITY WITH PEAK WINDS OF UP TO 190 MPH AS IT

APPROACHED THE FLAT ROCK AND HIGDON COMMUNITIES. THE TORNADO KILLED

ANOTHER THREE FROM THE SAME FAMILY AT A RESIDENCE SOUTHWEST OF FLAT

ROCK. THE TORNADO MOWED THOUSANDS OF TREES IN A 1/2 TO 3/4 MILE PATH

WIDTH. ONE WELL BUILT BLOCK FOUNDATION HOME LITERALLY EXPLODED AS THE

TORNADO STRUCK...LIFTING AND SWEEPING ALL ITS STRUCTURE AND CONTENTS

DOWNWIND...IN SOME CASES SEVERAL HUNDRED YARDS.

HOWEVER...MIRACULOUSLY...A MOTHER AND THREE CHILDREN TAKING REFUGE

IN A HALLWAY WERE COMPLETELY UNHARMED. AT THIS FARM...ALL FENCING

WAS DESTROYED AND UP TO 19 CATTLE WERE KILLED. TWO CHICKEN BARNS

WERE COMPLETELY OBLITERATED AND SWEPT AWAY UNIDENTIFABLY. A PROPANE

TANK WAS LIFTED FROM THE PREVIOUS LOCATION OF CHICKEN BARNS AND

DROPPED OVER 100 YARDS AWAY IN FRONT OF THE DESTROYED HOME.

** UPDATED FROM STORM SURVEY TODAY /MAY 1/ OF CONTINUED DAMAGE PATH

FROM HIGDON/SHILOH TO GEORGIA/ALABAMA STATE LINE **

THE TORNADO CONTINUED ITS WIDE PATH AND VIOLENT DESTRUCTION ACROSS

THE NORTHERN TIP OF DEKALB COUNTY IN THE SHILOH COMMUNITY. THE

TORNADO KILLED UP TO 5 PEOPLE IN THIS AREA. SEVERAL CINDER BLOCK

FOUNDATION HOMES AND MOBILE HOMES WERE COMPLETELY DESTROYED OR

SWEPT AWAY. IN ADDITION...THOUSANDS OF LARGE TREES WERE SHEARED OFF

TOWARD THE BASE. AN OLDER TWO-STORY /FAIRLY WELL-BUILT/ LOG CABIN

WAS DESTROYED. THE TOP STORY OF THIS HOME WAS LIFTED OFF...MOVED

ABOUT 20 YARDS AND TWISTED 180 DEGREES. THE LOWER STORY COLLAPSED

AND WAS SHIFTED OFF ITS FOUNDATION. A SENIOR CITIZEN VAN WAS LOFTED

AND DROPPED INTO A FIELD NEARLY 400 YARDS AWAY. AT LEAST THREE

CHICKEN BARNS WERE COLLAPSED WITH A HIGH LOSS OF LIVESTOCK NOTED.

THE TORNADO CROSSED INTO DADE COUNTY GEORGIA WITH A 1/4 TO 1/2 MILE

WIDE PATH ALONG COUNTY ROAD 155 NORTH OF HIGHWAY 75.

THESE FINDINGS ARE PRELIMINARY AND ARE SUBJECT TO ADJUSTMENT.

Sorry 2 EF4s in Jackson County.

NP, hell it's late I missed time stamp on latest PNS. Guess my question would be....Is it just a continuation of the earlier EF4 or being considered a totally separate storm? Per their map it may have been same storm just path length and locations added as it moved north and area surveyed???
