As of 10:55 a.m., Pepco was reporting 66 outages affecting more than 2,400 customers in Montgomery County, according to the utility’s outage tracker.
Belak said Friday’s rainstorm won’t be as severe as a summer flooding event.
“We’re looking at a longer duration, soaking sort of rain,” he said.
Belak cautioned drivers to “turn around, not drown” if they see high water. Additionally, fallen leaves can clog storm drains during this time of year, he said.
