"Arrow's" Season Five premiere on Wednesday suffered the same fate as "The Flash," with a drop in viewership compared to last fall's season opener.
According to TV By the Numbers, "Arrow" attracted 1.89 million total viewers, good for a 0.7 rating among adults 18-49. That's down four-tenths of a point compared to the Season Four premiere, and about two-tenths from its 2015-2016 average.
However, it should be noted that "Arrow" was a victim of unforeseen circumstances, with many television stations in the Southeast preempting their primetime schedules for coverage of Hurricane Matthew. The storm is being reported as one of the largest in history, so one can understand residents choosing updates of its trajectory over watching the CW lineup.
There was also an Major League Baseball's National League East Wild Card game between the San Francisco Giants and the New York Mets, cities that are home to large TV markets. The game started at the same time as "Arrow," so it was another deciding factor in final ratings.
Finally, although "Luke Cage" premiered on Friday, it's reasonable to assume viewers are still barreling through the first season of the Netflix drama.
Starring Stephen Amell, "Arrow" airs Wednesdays at 8 pm ET/PT on The CW.
