State of Emergency in Maryland
Strong thunderstorms and flooding was expected today, but not like this. This was worse than the once in a lifetime flood just 2 years ago in this same area. The photos tell it all (Main Street raging as seen from Shannon Baranoski). This breaks my heart, as with many of you. My Maryland Trek goes right down this road each August and we were rerouted in 2016 due to that flood. It is impossible to imagine what local business are dealing with, many of whom just recently opened back up again.
The rain that developed over central Maryland was along a stationary front that helped the storms develop and track over the same locations, called training. About 1000 miles away, Subtropical Storm Alberto was gaining strength in the Gulf of Mexico, but did help send some tropical moisture this far north. The net result was the focus of the heaviest rain over the worst area that resulted in nearly 6 inches in 2 hours and a total of 8 inches estimated by Doppler Radar. Weather Bug Station in Waverly ES recorded 7.45″ of rain for the day. Nearby BWI Airport average 3.99″ for the entire month of May! Some local stations report up to 10 inches for the event.
Ask locals and they know the history of heavy rain and floods on Main Street in Ellicott City. But many will say the overdevelopment and poor planning for the drainage

This is the National Weather Service Doppler Radar from Sterling VA between 3 PM and 8 PM. Watch as the storm evolved, then sit and dump over the same areas.
Power of Water
This is a snapshot from the video below, thanks to Christa Rose. The water level was higher than the 2016 event, but the water raging through the buildings out into the street was amazing.
Flooding on Main Street in Ellicott City
Watch closely and see the force of water raging out of the buildings. This was much worse than the 2016 storm.
