The macroburst toppled/uprooted hundreds of trees.
Some trees fell on structures. There was limited 
direct damage from wind to structures with a fallen

few homes.

The damage is consistent with wind speeds in the

rotation...used to differentiate from tornadic 
winds.

Macrobursts can produce as much if not more damage
as tornadoes due to the size and scope of a 
macroburst.
