Nearly 600,000 customers were without power in New England on Wednesday after a record-breaking nor’easter devastated the region.

Heavy rain flooded roads from Massachusetts to New York, while water rescues were reported in New Jersey.

Dangerous winds also toppled trees and blocked roads.

One person was killed in Morris Township, New Jersey, when a tree limb fell on two cars Wednesday morning, according to ABC New York station WABC.

The storm became a “bomb cyclone” when its pressure dropped 24 millibars in less than 24 hours. In Nantucket, Massachusetts, the nor’easter set a record for the lowest pressure ever recorded in October.

The heavy rain should be ending in most of the Northeast on Wednesday, but winds will continue to roar up to 60 mph from Long Island to Massachusetts to Maine. On Wednesday morning, gusts approached 80 mph in Cape Cod, Massachusetts.

More power outages are possible Wednesday in New England. By 7 p.m., wind gusts could still reach near 50 mph in Massachusetts.
