It came with little warning, not expected to maintain its strength across a path that started in the Midwest.

But the line of storms known as a derecho nonetheless hit Baltimore with sustained 70 mph winds, one of the region's worst weather disasters in a generation.


The storm killed two people in Maryland and some 20 others across the mid-Atlantic. And it left hundreds of thousands of residents without power amid dangerously sweltering heat.

Here is what people had to say about the storm at the time, and in its aftermath:

  • "I think it was one of the worst storms we had, as far as how quickly it came up," said Homeland resident Melissa Kitner-Triolo. "It was the wind more than anything. At first, you didn't hear the rain so much. It was like a microburst. It was pretty terrifying."

  • "The widespread nature of the image we saw is a very rare occurrence," said National Weather Service meteorologist Stephen Konarik. "We would not have been planning on that magnitude of event."

  • A derecho with such intensity happens in the mid-Atlantic once every five to seven years, said Greg Carbin, warning coordination meteorologist for the storm center in Norman, Okla.

  • "We didn’t have absolute certainty plus a time angle as well that it would make it to the Chesapeake Bay," said James Lee, meteorologist in charge for the weather service’s Baltimore/Washington forecast office. "These are exceedingly rare events. Seeing these things go through and being able to forecast them accurately, you’ve really got to weigh that."

  • "I missed two weddings, and [my wife] ended up eating two dinners by herself," Maryland Emergency Management Agency Director Ken Mallette said. "But that's part of the job."

  • "During the June Derecho restoration, it was once again apparent that there is a disconnect between customer expectations of what is a reasonable [restoration time] in the aftermath of a severe impact storm and the realities associated with restoring power under such conditions," Baltimore Gas and Electric Co. officials wrote in a report on its response to the derecho.

  • "What we found is especially during some of these severe events, even if you trim back, you still have some of these large black locust trees with shallow roots that can take the wires down," said Mike Garzon, a BGE reliability project manager.
