ZIPPs is in the process of closing for a month to allow for the return of the hurricane season.
The company announced Thursday that its stores will stay open through Labor Day and will continue to be open until further notice.
The company also announced a $100,000 donation to the Red Cross for storm relief efforts.
The storm’s impact was felt in several cities across the country.
In Miami, for example, about 50,000 customers lost power in the city of about 2 million.
In Tampa, Florida, more than 500 homes and businesses were damaged or destroyed, and some 200 people were reported missing.
Zipps said it was working to ensure that customers and employees were prepared for a storm that is expected to be heavy.
“As a result of the severe weather forecast and the significant damage in our stores, we are asking for your patience and your understanding during this time,” the company said.
“Our stores will be closed for the foreseeable future, and we are offering our heartfelt condolences to our customers and the victims of this storm.”
ZippS said it has received a large number of calls from people in Florida and elsewhere asking how to prepare for the storm.
