...NWS Damage Survey For March 29, 2017 Metroplex Tornadoes and Damaging Winds...
...Updated to include Lewisville tornado and Rockwall wind damage...

.Overview...National Weather Service damage survey crews investigated several
areas of damage from winds and possible tornadoes early on the morning of March 29th.
While additional surveys will continue over the next several days, as of this evening, two
tornadoes have been confirmed.

In Rockwall, the damage survey crew determined a downburst caused the most significant
damage of the morning. This downburst produced a wide swath of damage near the intersection
of FM 1141 and FM 552. In this area, the downburst destroyed three homes, as winds near 95
mph caused significant damage to roofing materials, failure of garage doors, and broken
windows in the homes. Debris from these homes produced a damage path to the east and northeast,
causing additional damage to several other homes.

Survey_Summary: The team found damage consistent with an EF-0 tornado,
with peak winds of 85 mph. Tornado damage was first encountered along
Western Center Boulevard, west of I-35W in North Fort Worth. Here, a
series of large oak tree limbs were snapped, and some superficial damage
to some commercial buildings was observed. The tornado crossed I-35W
north of the Western Center Blvd overpass, producing roof damage to
multiple apartment complexes on the east  side of the Interstate.
Damage continued in a northeast direction, most notably snapping
power poles and impacting the roof of a large retail store near the
corner of North Tarrant Parkway and U.S. 377 in far southwest Keller.
The path of the tornado was at its widest in this area, approaching
500 yards in width. Damage consistent with 85 mph winds was observed
near this intersection, with multiple indications of rotation. The
tornado continued through Keller, weakening and narrowing in width
as it crossed Davis Boulevard and entered western Southlake. The
magnitude and nature of damage over this portion of the path was
consistent with a 65-85 mph tornado. No appreciable damage was found
beyond FM Road 1709 and Shady Oaks Drive, and the tornado is believed
to have dissipated near this location.
