20 June 2015
It’s a summer weekend here in the Mid-Atlantic, and that means thousands are on the beaches from Fire Island To Ocean City in Maryland, while at the same time, the Firefly music festival just north of Dover in Delaware has drawn a crowd of 95,000 people to see such acts as Paul McCartney (I typed that name standing up of course) and Snoop Dog. Now, add in the remains of Bill (and a very tropical air mass) and you have the potential for big trouble.
Bill has maintained a distinct identity much longer than any recent tropical cyclone I can remember (see Brown Ocean Effect and note the papers below the wiki entry), although it is now an extratropical low pressure. It will still produce a lot of rain over the Mid-Atlantic tonight, and perhaps severe storms as well as it approaches. With thousands camping at Firefly and potential of flash flooding, forecasters like me are on high alert.
I tweeted out the image below earlier today as a reminder that lightning kills. Flash floods kill more though.
