The American Center for Physics is open today with normal business hours.
This site will be updated at 6:00 AM when inclement weather and/or and emergency has occurred.
Because weather and driving conditions may vary significantly across the Washington, DC region, each employee must make his/her own decision about roadway conditions for traveling. In cases of questionable weather, each society has implemented a liberal leave policy, which means that individuals may decide to use their accumulated vacation time in cases when the building is not closed. However, if you decide to use a vacation day and not come to work when the building is open, you should call your office to inform your supervisor that you wish to use your option of liberal leave.
