Frederick, MD Flooding conditions have closed many roads across Maryland, particularly in the Frederick area, Monday morning.

Heavy rainfall moved through much of Maryland throughout the morning prompted the National Weather Service to issue flash flood warnings and flood watches.

WBAL-TV 11 Weather meteorologist Lowell Melser said very heavy rain moved through Frederick, Montgomery, Carroll and Baltimore counties around 8 a.m.

WBAL-TV 11 Weather meteorologist Tony Pann said close to 5 inches of rain have fallen in parts of Frederick County. As many as 20 roadways were flooded and 11 vehicles were stranded in high water in Frederick Monday morning.

"I think it's amazing. The power of water, it's so fascinating," said Barbara Barry, a Frederick resident.

Dozens of people came out to Baker Park in Frederick to witness it firsthand along Carroll Creek. Frederick got a deluge of rain in the early morning hours, flooding out more than 20 major roadways. Eleven vehicles got stranded in the rising water.

"I was here in 1976 when they had the great Frederick flood, and this is one of the reasons why they built this project so that it wouldn't flood the downtown area, so to see that its working is just amazing," said Raynard Wars, Frederick resident.

Police said there were at least a couple of water rescues but amazingly, no injuries. By midday, most of the water had receded off roadways but Baker Park looked more like a lake around the bell tower. Jose Campos and his kids were catching fish in leftover puddles, to put them back into nearby Culler Lake.

"It was all hands-on deck this morning, so even our specialty units were out assisting with road closures, helping people find alternate routes," said Michele Bowman, of the Frederick police.

It looks like the city's got a lot of work ahead of it, but you can't predict these kinds of things," said Dennis Hoffman, Frederick resident.

"We've been getting the warnings throughout the night that kind of thing, but when that amount of rain falls that quickly, you're going to see flooding. Roads that we have not seen flood before actually had water covering them this morning," said Bowman.

"We just walk around and if we see something red, we try and catch it, and if it moves, it's a fish," said Nicholas Urretar, who was out catching fish.

The receding water left behind with a big mess, lots of debris around the lake and on roadways throughout the city.

"We're asking people to please use caution when driving, especially on their way home from work. Our DPW crews are out trying to get everything cleared as quickly as they can, but obviously it’s going to take a little bit of time," said Bowman.

It will also take time for Carroll Creek and the spillway to return to normal, but some residents are enjoying watching it do its work.

"We should put some colored lights on it at night like Niagara Falls," said Barry.

Water rescues were reported in parts of Montgomery County.

Gov. Larry Hogan tweeted a statement, saying, "Much of our region is experiencing torrential rain that may cause flash flooding. These conditions will likely prove challenging for morning and afternoon commuters.

"Please take all safety precautions while driving in severe weather conditions. These include using your headlights, increasing following distance, and decreasing your speed. Never drive through standing water -- turn around, don't drown.

"Our office is monitoring the response and will continue to coordinate with state agencies to ensure Marylanders' safety."
