First the winds and now the rains.

Oklahoma suffered powerful thunderstorms on Friday that led to widespread flooding.

And this after multiple tornados ripped through the state earlier in the day, killing five people.

Hospitals are treating over 40 people for storm-related injuries, caused by winds of up to 90 miles per hour.

Meteorologists declared a tornado emergency for parts of Oklahoma City.

And one twister touched down in the city of Moore, the site of last week's storms that killed 24 people.

Utilities companies say over 170,000 customers were without power in Oklahoma and neighbouring states in the region known as Tornado Alley.
