Today is the 4th and expected to be the final day of our unusual early heatwave. While 1000-2000 people at a time have been without power on average, it seems that Con Ed has thus far done a good job at keeping all of our ACs running. Of course there have been some burnt out feeder cables, low voltage in Yorkville and varied subway delays and disruptions, but as a whole things seem to be holding up rather well (I hate to jinx it). Right now 1480 customers are without power with several outages in the West Bronx and Crown Heights.
