Original sentence: Additionally, the overpass design may create a "wind-tunnel" effect under the span, further increasing the wind speed.All of the individuals received significant injuries from tornadic debris, and several were swept into the tornado itself.From lessons learned in the 1999 Oklahoma outbreak, and for scientific reasons, meteorologists insist that overpasses are insufficient shelter from tornado winds and debris, and may be the worst place to be during a violent tornado.Many overpasses are completely exposed underneath and most lack hanging girders or a crawlspace-like area to provide sufficient protection from debris, which can travel at high speeds even in weak tornadoes.People stopping underneath overpasses block the flow of traffic, putting others in danger.The tornado did not pass directly over the filmed bridge, but instead tracked slightly south of the area, exposing the people to winds less damaging than those in the tornado core
Edited sentence: Additionally, the overpass design may create a "wind-tunnel" effect under the span, increasing the winds further.All of the individuals received massive injuries from tornadic debris, and several were swept into the tornado itself.Even worse, people stopping underneath overpasses blocks the flow of traffic, putting others in danger unnecessarily.From lessons harshly learned in the 1999 Oklahoma outbreak, and for many scientific reasons, meteorologists insist that overpasses are insufficient shelter from tornado winds and debris, and may possibly be the worst place to be during a violent tornado.Many overpasses are completely exposed underneath and most lack hanging girders or a crawlspace-like area to provide sufficient protection from debris, which can travel at deadly speeds even in weak tornadoes.The tornado did not pass directly over the filmed bridge, but instead tracked slightly south of the area, exposing the people there to winds less damaging than those in the tornado core
