LINDENHURST - Nassau and Suffolk counties' governments fully mobilized this weekend ahead of Hurricane Sandy's landfall.

Gov. Andrew Cuomo (D - NY) visited Long Island Sunday to urge residents to take the strong storm seriously. Cuomo also announced the deployment of 1,100 National Guard troops for emergency response.

Nassau County Executive Ed Mangano said he and other officials are preparing for the worst. Mandatory evacuations are in effect for areas south of Sunrise Highway from the Queens line to Rockville Centre, and south of Merrick Road, from Rockville Centre to the Nassau-Suffolk border.

Suffolk County Executive Steve Bellone also ordered evacuations for Fire Island and communities further east. Bellone stated that the Long Island Power Authority (LIPA) will be de-energizing Fire Island in order to prevent fires.

Shelters are opened in both counties, including a pet-friendly one at the Athletic Complex at Mitchell Field and one at Nassau County Community College for those with special needs.

In August 2011, Hurricane Irene brought widespread flooding and power outages across the Island.
