The US search engine giant has also introduced a special 'crisis map' online enabling people to prepare for the expected high winds and flooding.
Google had intended to run a major Android event on Monday (October 29) in New York City, at which it was expected to unveil a new Nexus 4 smartphone and Nexus 10 large-screen tablet, as well as announce updates to the Android software and the Nexus 7 tablet line.
However, New York governor Andrew Cuomo has declared a state of emergency in response to the Category 1 hurricane, which is expected to hit the US mid-Atlantic coast from Virginia to Massachusetts with 85-miles-an-hour winds.
New York City subway systems and commuter trains and buses have already shut down, while the major stock exchanges have suspended all trading for Monday and Broadway theaters cancelled their shows.
Google's event was scheduled to take place on a waterfront pier in the city, but that is now in an evacuation zone.
This is the second time that Google has postponed a launch event in recent memory, after last year's Android Ice Cream Sandwich launch was moved as a mark of respect following the death of Apple co-founder Steve Jobs.
Google's 'crisis map' provides specific information regarding Hurricane Sandy to help people who could be affected.
The map shows the storm's current position, along with a three-day forecast and flood risk warning. There is also detailed information on evacuation routes and the placing of emergency shelters.
