SAO PAULO (AP) — Heavy rains and thunderstorms in Brazil's biggest city left hundreds of thousands of people in the dark for several hours, a power distribution company said Tuesday.

Sao Paulo's AES Eletropaulo said on its website that a Monday night rainstorm with winds of more than 50 miles (85 kilometers) per hour and close to 8,000 lightning strikes left 800,000 clients without energy. A similar storm on Dec. 29 left 500,000 Eletropaulo clients without electricity.

Monday's rainstorm occurred after temperatures reached 35.4 degrees centigrade (95 degrees Fahrenheit). It flooded at least 30 streets and several neighborhoods and knocked down close to 80 trees and many of the city's overhead power lines.

Departures and arrivals at Sao Paulo's Congonhas were suspended for more than an hour.

In Rio de Janeiro, a power outage hit the city's Tom Jobim international airport leaving hundreds of passengers in the dark for about two hours.

The company that manages the airport said the cause of the outage was not known.
