If your power is still out, you can check Entergy's Facebook for more information. They have a list of neighborhoods affected and a timetable (though somewhat vague) for getting the lights back on. They say all power should be restored by Tuesday.
They have customer information centers open during the daytime to answer any questions. The centers are open 10 a.m. at 900 S. Louisiana Street in Little Rock, the Entergy Building at 324 Malvern Avenue in Hot Springs, and the Malvern Chamber of Commerce Building at 213 West 3rd Street. You can meet in person with company representatives to discuss their outages. Detailed CIC location information will be available starting tomorrow to customers who call 1-800-9OUTAGE (1-800-968-8243), press option 6 and enter their ZIP code.
The city is using Dunbar Community Center as a warming center and overnight shelter. Southwest Community Center is used as a warming center from 10 a.m. to 6 p.m. Many local restaurants are offering warming and cell phone charging to those without power.
