Mayor Bloomberg's office has teamed with Google to create Hurricane Sandy: NYC. It's a handy "crisis" map that links to the latest N.Y.C. Emergency Management alerts, various city-related Twitter accounts and advisories about Hurricane Sandy from the National Hurricane Center.

Residents may be particularly interested in the map's color-coded evacuation zones--currently Zone A is under a mandatory evacuation order.

Here are Google's tips on how to best use the map:

• Zoom the map using either the on-screen controls or your mouse.
• Find additional layers in the Layers list, where you can turn them on or off. Scroll to see all layers.
• Zoom to an appropriate view for each layer by clicking the "Zoom to area" links in the Layers list.
• View selected layers in Google Earth by clicking the "Download KML" links in the Layers list.
• Share the map in e-mail by clicking the Share button and copying the URL provided there. The URL will restore your current view, including the set of layers that you have turned on.
• Embed the map on your website or blog by getting a snippet of HTML code from the Share button.
• Share the link on Google+, Twitter or Facebook by clicking the appropriate button in the Share window.
