NWS Confirms Tornadoes In Blount and Marshall Counties Monday Morning

The National Weather Service in Birmingham has confirmed 2 tornadoes touched down in Blount County Monday Morning, April 8th. The first developed near Hayden as a EF-0 with winds of 85mph. This first tornado only lasted about 2.2 miles. The second tornado was on the ground for 6.3 miles just south of Brooksville. This second tornado was rated an EF-1, and produced winds up to 90 mph before dissipating just before moving into Marshall County.

The National Weather Service in Huntsville confirmed another EF-1 tornado developed within that same storm cell near Guntersville, about 20 minutes after tornado in Blount County ended. The NWS has estimated winds of 90-100 mph in the Marshall County tornado.

These three tornadoes bring the year’s total tornado count since January 1st up to 40. For perspective, the ‘average’ number of tornadoes seen by April 8th is closer to 10. That number comes from a combination of ‘quiet’ years and ‘active’ years, that even out to around 10 tornadoes through the first week of April.

The surveys for all three tornadoes are below in full:

SUMMARY:

NWS AND MARSHALL CO. EMA DAMAGE ASSESSMENT TEAMS RECORDED
TORNADO DAMAGE CONSISTENT WITH AN EF-1 TORNADO WITH WINDS PEAKING
AT 100 MPH.

THE MARSHALL CO. TEAM TRACKED THE INITIAL TOUCHDOWN OF
THE TORNADO SW OF THE INTERSECTION OF HIGHPOINT RD/MCALLISTER RD AND
NORTH OF BEARDEN RD. NUMEROUS HARDWOOD TREES WERE EITHER UPROOTED
OR HAD LARGE LIMB DAMAGE. AS THE TORNADO APPROACHED HIGHPOINT
RD, IT CAUSED MINOR ROOF DAMAGE TO TWO SINGLE FAMILY HOMES AND
DESTROYED A LARGE SHED, THAT WAS UNANCHORED TO ITS FOUNDATION.
DAMAGE INDICATORS FURTHER UPSTREAM WERE CONSISTENT WITH THE
ASSESSMENT AT HIGHPOINT RD. A MIX OF HARDWOOD AND SOFTWOOD
TREES WERE EITHER SNAPPED OR UPROOTED ALONG PORTIONS OF NIXON
CHAPEL RD AND SECTION LINE RD. A MORE CONCENTRATED AREA OF
HEAVY TREE DAMAGE, WITH SIGNIFICANT MOBILE HOME ROOF DAMAGE
AND MINOR SINGLE HOME ROOF DAMAGE, WAS NOTED IN AN AREA BETWEEN
WINDSOR RD AND MT. OLIVE RD, LIKELY WHERE THE TORNADO PEAKED
IN INTENSITY.

THE TORNADO CONTINUED NNE TOWARD HWY 431. THE TORNADO STARTED TO
QUICKLY WEAKEN AS IT CROSSED THE ONEONTA CUTOFF RD/TURNPIKE RD/CR
205 JUNCTION. SPORADIC TREE DAMAGE WAS OBSERVED AROUND THIS
LOCATION, CAUSING POWER LINE DAMAGE. FINALLY, THE TORNADO
APPROACHED HWY 431 AND DAMAGED AC UNITS AND CAUSED MINOR ROOF
DAMAGE TO TWO LARGE RETAIL BUILDINGS. VERY MINOR LIMB DAMAGE WAS
NOTED NORTH OF 431 WHERE THE TORNADO DISSIPATED.

EF SCALE: THE ENHANCED FUJITA SCALE CLASSIFIES TORNADOES INTO
THE FOLLOWING CATEGORIES.

EF0…WEAK……65 TO 85 MPH
EF1…WEAK……86 TO 110 MPH
EF2…STRONG….111 TO 135 MPH
EF3…STRONG….136 TO 165 MPH
EF4…VIOLENT…166 TO 200MPH
EF5…VIOLENT…>200MPH
