The tarp is on the field at Nationals Park, and the start of tonight's Nationals-Orioles game will be delayed. The storm system currently dumping rain on Nationals Park looks to be blowing through pretty quickly, though, so we should be underway before too long.
We'll keep you posted on the start time. And if you're at the park, you might be able to see the double rainbow behind right field. It is not, at this time, starting to look like a triple rainbow, however.
Update: The rain has passed through, blessedly cooling it off here at the ballpark. We'll get started at 8:05.
