Law firms and the courts scrambled this morning to keep employees safe and to maintain some semblance of normal operations as waters lapped over Manhattan sea walls. Courts and some firms closed, but many lawyers came to work and others worked remotely. But howling winds were a reminder that it was uncertain how long power would be available.

Fried, Frank, Harris, Shriver & Jacobson downtown at One New York Plaza, close to the Staten Island Ferry, is in Zone A, the area under orders to be evacuated. Janice MacAvoy, a partner and co-head of the firm’s real estate litigation group said the firm’s office in Washington, D.C. — also in the path of the storm — is closed as well.
