Extensive structural and tree damage occurred from the eastern portions of Westwood  eastward into the Clifton area. Damage in this area was determined to be  a result of straight-line winds.
Some of the most significant damage from straight-line winds occurred in East Westwood along Westwood Northern Boulevard. Two brick two story apartment buildings were damaged. Much of the roof of one building was removed and a significant portion of the other was blown off and thrown behind the buildings. Some debris from the second level of the buildings was also tossed behind both buildings. In addition, several large tree branches were knocked down, and these branches were generally pointing toward the same direction.
To the east of Interstate 75 in the Clifton area, additional damage was surveyed. Much of the damage consisted of large healthy tree limbs being knocked down and a few evergreen trees being uprooted, particularly along Senator Avenue. Chimney damage was also noted on one home and a portion of the roof of a church on Clifton Avenue was also removed. Damage in the Clifton area exhibited a pattern consistent  with straight-line winds which likely were in the 90 to 100 mph range.
