(Harrisburg) -- As forecasters keep a close eye on Hurricane Irene, the Pennsylvania Emergency Management Agency is reminding people to prepare for high winds and heavy rains this weekend. PEMA says while the storm is expected to primarily hit the southeastern part of the state, residents should remain ready to deal with its impact. Across the state, utility crews, airports and other agencies have extra personnel on stand-by to help deal with potential problems. The American Red Cross says it's getting shelter supplies ready in low-lying areas in the event that evacuations have to be ordered.

PEMA says if roads become impassable or power is lost, people should be prepared to survive on their own for at least three days.

Here are some tips issued by the agency:

Residents should have disaster preparedness supplies on hand:

Flashlights and extra batteries

Portable, battery-operated radio and extra batteries

First aid kit and manual

Emergency food and water

Non-electric can opener

Essential medicines/prescriptions

Cash, credit cards and important legal documents

Sturdy shoes

If residents are ordered to evacuate, they should take:

Checkbooks

Driver's license;

Credit card information;

Birth certificates;

Social Security cards; and

Other forms and documents proving ownership/identity.

Never drive into low-lying areas or over roads and bridges that are already under water. Just a few inches of moving water can sweep away the average car.

Individuals and families need to have a communication plan in place in order to contact or find each other if separated. As the storm approaches, residents should listen to and closely follow instructions from local and state authorities.
