End Lat/Lon:            31.5638 / -95.1043

Storm Summary:

Tornado first touched down in a rural field approximately 2 miles north of
the Neches River which is also the Cherokee County and Houston County
line. It initially snapped several hundred softwood and hardwood
trees at their trunks before destroying two single wide mobile homes and
ripping the roof off of a single family home at the end of Route 220 near
CR 2806.  There, winds were estimated to be the strongest at approximately
120 mph. The storm also tossed several antique vehicles near the home and
then went on to snap another 20 trees before lifting.


.Tornado #2 in Cherokee County Texas in Alto...

Rating:                 EF-2
Estimated Peak Wind:    120 mph
Path Length /statute/:  2.5 miles
Path Width /maximum/:   400 yards
Fatalities:             0
Injuries:               0

Start Date:             04/13/2019
Start Time:             11:52 AM CDT
Start Location:         1 SSW Alto / Cherokee County / TX
Start Lat/Lon:          31.6405 / -95.0805

End Date:               04/13/2019
End Time:               12:00 PM CDT
End Location:           2 N Alto / Cherokee County / TX
End Lat/Lon:            31.6759 / -95.0721

Storm Summary:

The same storm that produced Tornado #1 lifted as a funnel cloud for
approximately 5 miles and then dropped again, counting as a second tornado
on the southern edges of Alto. There, it first damaged structures along
Highway 21, Blaton St, and Putnam Ave. Damage included shifting a single family
home off its foundation and significant roof damage to another home on Quincy
Avenue. Several other homes sustained structural damage as the tornado went through
the west side of Alto and then crossed Highway 69. The tornado then moved
across the Alto ISD and damaged its gymnasium and roofs to structures on the campus.

Please note that if a tornado lifts up for more than 2 miles and then touches
down again, it is classified as another tornado as was the case here. In addition,
the damage tracks of two tornadoes crossed very near the Alto ISD, with several
structures noting damage from both tornadoes. With this rare occurrence of two
tornadoes crossing paths and hitting the same town in the same day, it made it
difficult to decipher damage which occurred from the first tornado with damage that
occurred from the second tornado. Much appreciation goes out to UT-Austin, the Texas A&M
Forest Service, the Civil Air Patrol, media partners, TDEM, and Cherokee County
Emergency Management for their assistance in this survey.


.Tornado #3 in Cherokee County Texas in and near Alto...

Estimated Peak Wind:    160 mph
Path Length /statute/:  29.4 miles
Path Width /maximum/:   880 yards
Fatalities:             1
Injuries:               20

Start Date:             04/13/2019
Start Time:             1:20 PM CDT
Start Location:         7 SW Alto / Cherokee County / TX
Start Lat/Lon:          31.5797 / -95.1653

End Date:               04/13/2019
End Time:               2:00 PM CDT
End Location:           8 NE Reklaw / Rusk County / TX
End Lat/Lon:            31.9046 / -94.8587

Storm Summary:

This tornado continued on the ground as it crossed the Neches River from
Houston County to Cherokee County. The storm snapped and uprooted
thousands of trees along its path. The storm paralleled Highway 21 before
reaching Alto, where it severely damaged or destroyed approximately 20
homes. Included along the damage path southwest of Alto was the Caddo Mounds
State Historic Site building, which had its roof torn off, nearly almost all
of its exterior walls removed, and was left to only a few interior rooms in
the building. Several people were outside running to get inside for safety
when the building was destroyed, resulting in a fatality and serious injuries.
Multiple cars in the parking lot were thrown 150 yards into trees and across
Highway 21. The tornado then went on to lift and destroy a double wide mobile home,
throwing it 50 yards. As the tornado continued along Highway 21, its most significant
damage along this road was at a single family home and the St. Thomas Chapel which
saw their roofs removed and exterior walls collapsed. Winds were estimated at
150 mph at this point.

As the tornado neared Alto, it destroyed three homes along Route 294 and
Singletary St, recording high end EF-3 damage as it wiped the lower level
of a two story home off of its foundation and left the top story of the home
20 yards away from the foundation. This damage was reviewed by tornado damage
experts from Southern Region HQs, WFO Norman, and the Warning Decision Training
Division who all agreed it was high end EF-3 damage based off how the home walls
were separated from the bolts which anchored them to the foundation. Surrounding
damage indicators also validated the EF-3 determination.

The storm then went on to destroy several homes and mobile homes nearby
Alto Elementary and Alto High School. It also snapped a metal power pole before
crossing Highway 69. The storm continued on to snap and debark several trees in rural
Cherokee County north of Alto. The storm then continued on to remove the large
section of a roof in Sacul and crossed into extreme southwest Rusk County before
lifting. Between the WFO Houston and WFO Shreveport forecast areas, the tornado was
on the ground nearly continuously for approximately 44 miles.

Much appreciation goes out to the Cherokee County and Nacogdoches County
emergency managers along with the Smith County team that setup an Incident
Command Post in Alto and provided helpful damage information throughout the
survey.

End Lat/Lon:            31.4816 / -94.3726

Storm Summary:

This tornado touched down along County Road 442 a few miles southwest of
Chireno, where numerous trees were snapped or uprooted in a heavily wooded
area, while continuing northeast along and across County Road 443. The tornado
lifted just east of County Road 443, although the rear flank downdraft from
this storm tore off a 100 ft section of tin roofing from a vacant chicken house
just off of County Road 442. Portions of the roofs from three other vacant
chicken house were partially lifted up about two inches. Damaging straight line
winds of 80-85 mph from this same storm uprooted a tree in front of the Chireno
ISD building on Main Street, with numerous trees downed in a north northeasterly
direction along Highway 27 about 1-2 miles east of Chireno near the San Augustine
County line.

Storm Summary:

Straight line winds were found intermittently along a path from south of
Nacogdoches to west-northwest of Martinsville. This was determined based
off trees that were snapped and uprooted falling in the same direction. The
most persistent damage was found at the intersection of CR 239 and Route 2713.
At this location, approximately 50 trees were downed, the roof of a chicken
house was partially damaged, one home sustained roof damage, and another had
windows broken.

A special thanks goes out to Nacogdoches County Emergency Management for
their assistance in the storm survey.
