The "Now" column shows the number of customers currently without power in each county. The "Past Outages" columns identify the number of customers without power at the same time of day as shown below over the past 8 days.
Excluding major weather
events, the "Past Outages" numbers are typically different customer(s) that have
experienced outages over the last 8 days in that county and not the same
customer(s) out for the entire duration.
