Northeast/Mid-Atlantic: Eight states, including Connecticut, Delaware, Maryland, Massachusetts, New Jersey, New York, Pennsylvania and Rhode Island, had a record warm August. Connecticut and Rhode Island had their warmest summer on record. California had its warmest summer on record, which contributed to an active wildfire season.
