Bad news, kids: Mayor Vince Gray announced today that D.C. public schools are reopening tomorrow after being closed for two days for Hurricane Sandy. On the plus side, though, the mayor says trick-or-treating should be fine.

At an afternoon press conference, Gray said that there should be no weather issues tomorrow during what he described as “the trick-or-treat process.” Still, the mayor urged adults traveling with trick-or-treaters to watch out for storm debris. No word on Gray’s costume yet, although he has been likened to a vampire in the past.

On other Sandy-related issues, Gray praised residents for staying inside and D.C. government workers for responding to the storm. “Everyone really knew her or his job, and really worked as part of a team,” Gray said.

Residents are asked to stay off the streets today if they can to make cleaning easier for city crews.

But while Sandy is gone, its effects aren’t over yet. Homeland Security and Emergency Management Agency director Chris T. Geldart warned that a swollen Potomac could overflow in Georgetown and other riverside areas tomorrow night.
