We knew there would be rain, but check out this message from the Office of Emergency Management: "Alert issued 7/23/10 at 8:20 PM. The National Weather Service has issued a Tornado Warning until 9:00 PM for Queens, Brooklyn, Manhattan, and the Bronx. Immediately go indoors and/or to the lowest floor of your building for shelter. Stay away from windows." There's also a flood advisory for the city. But the lightning show has been nuts!
