A flash flood emergency was declared in Ellicott City on Sunday. A video posted by locals show the city’s Main Street awash with muddy water.

“This is an EXTREMELY DANGEROUS AND POTENTIALLY CATASTROPHIC situation and you must move to HIGHER GROUND IMMEDIATELY AND STAY AWAY FROM ANYWHERE WHERE WATER IS MOVING,” National Weather Service Baltimore said in a Twitter statement.

The flood warning was also issued for Baltimore. A video filmed outside the city shows cars abandoned on the streets being devoured by water.

Ellicott City, which is situated just 55 meters (180ft) above sea level, is experiencing flooding on the same scale as it saw in 2016, the Howard County government said. The 2016 Maryland flood caused severe damage to the historic center of the city, affecting many homes, businesses and famous sights. Two people perished at the time.
