BROOKLYN - City officials are warning Brooklyn residents today to take certain precautions in case Hurricane Irene strikes.

The city's Office of Emergency Management (OEM) is urging residents to put together emergency kits containing items such as water, non-perishable canned foods, first aid supplies and personal hygiene products.

In addition, residents are urged to have a "go" bag in case there are evacuations. Officials recommend placing items like Social Security cards and passports in waterproof containers and then into the "go" bag. They also say keep a list of medications and a regional map inside the bag.

OEM officials say in case of an evacuation, they will open up shelter systems that could hold up to 70,000 people.
