HOUSTON (AP) — Houston area residents affected by deadly storms last week received some good news as officials said power had been restored Sunday to a majority of the hundreds of thousands who had been left in the dark and without air conditioning amid hot and humid weather.

The widespread destruction of Thursday’s storms left at least seven dead and brought much of Houston to a standstill. Thunderstorms and hurricane-force winds tore through the city, reducing businesses and other structures to piles of debris, uprooting trees and shattering glass from downtown skyscrapers. A tornado also touched down near the northwest Houston suburb of Cypress.

By Sunday evening, 88% of customers in the Houston area had their power restored, said Paul Lock, a spokesperson for CenterPoint Energy.

“We expect everyone to be back on by end of business Wednesday,” Lock said.
