Isaias' heavy rains and gusting winds could pull down trees and power lines, causing widespread outages. PSEG says it is getting ready for that scenario.

Dan Eichorn, COO of PSEG, says they have their trucks geared up and ready to go. They also have 2,500 additional line workers coming from out of state.

"It has the potential to be one of the biggest storms we've had since Superstorm Sandy -- we don't expect it to be anywhere near Sandy," says Eichorn.

When it comes to residential outages, Eichorn says PSEG LI looks at what customers are impacted the worst.

"If their entire neighborhood is out, they are going to rise to our priority, they will be one of the first jobs we work," he says.

Town of Hempstead Supervisor Don Clavin says he wants residents to be ready for what could take place.

"I want residents to know that their government is prepared, we're working not only with Nassau County but villages in being prepared," says Clavin.

As for how to get information on outages, Eichorn says customers should go to their website and click on the outage map, or download their app. They say they will have up-to-the-minute information on their website on outages and where they are.
