Lowes, Target and Walmart have all been hit by power outages this week, with Target shutting down stores nationwide for the first time since June, and Walmart shuttering more than 1,100 stores.

Here are the most important things to know about outages at each retailer.

If you can, keep an eye on your local news.

Many of the issues can be traced to the solar eclipse, which began at 3:40 p.m.

ET Monday.

In New Jersey, there’s been a number of solar flare events this week that have been tied to the eclipse, including one at a gas station.

If you’re not sure what to look for, here’s a map to help you decide whether you should stay home.

If your electricity provider hasn’t yet said it’s shutting down the service for any reason, call the company and get in touch with them.

If they’re still offering the service, it could be for the foreseeable future.

If the outage lasts more than two hours, check your energy bill.

If it says more than 12 hours, that means your home or business isn’t connected to the grid.

If your bill is only showing one day, that’s because it’s still charging.

It’s a good idea to call the utility and ask if the problem is connected to your home.
