After flash floods sent cars floating down Main Street in historic Ellicott City, Maryland, local officials said they were heartbroken to see the community so severely damaged again, less than two years after a devastating flood killed two people and caused millions in damages.

As the flood waters receded late Sunday, officials were just beginning the grim task of assessing the destruction.

During an evening news conference, Howard County Executive Allan Kittleman said authorities weren't aware of any fatalities or missing people.

But first responders and rescue officials were still going through the muddied, damaged downtown, conducting safety checks and ensuring people evacuated.

Kittleman said the damage was significant and appeared to him to be worse than the flooding two summers ago.

Gov. Larry Hogan also toured the area and promised "every bit of assistance we possibly can."
