Malloy said the storm is moving more quickly and some the highest winds may ease in Connecticut around 10 p.m.
"If you've lost power, you're likely to be without power for an extended period of time," Malloy said at a press conference broadcast at 6 p.m., Monday.
The biggest concern Monday night remains the storm surge expected at high tide around midnight. The shoreline from Greenwich to Fairfield remains vulnerable to record flooding.
"Unless your life depends on leaving your home, then don’t," Malloy said.
Connecticut's power providers are better prepared for Hurricane Sandy than they were before Hurricane Irene, Malloy said.
But crews won't be able to begin restoring power unless sustained winds are below 40 mph, Malloy said.
