Severe storm warning for Oklahoma and Texas where tornados, flash floods, and power outages force some to evacuate

SEVERE storm warnings have been issued as Oklahoma and Texas brace for tornadoes, flash floods, and potential power outages, as some residents in hard-hit areas were evacuated, reports say.

The Storm Prediction Center (SPC) issued a level 4 out of 5 "moderate" risk for severe storms in parts of Oklahoma on Sunday, a warning that applies to more than 2million people across the state.

The storms could be capable of producing large hail, damaging winds, and even tornadoes on Sunday afternoon and overnight.

The storms are linked to a developing low-pressure system and a front that extends from the Midwest through the Southern Plains.

Around 11.30pm on Sunday, electricity company Oncor was reporting nearly 56,000 customers without power in the area of Dallas-Fort Worth.

Less severe storm alerts were issued on Sunday for several other states as well.

A level 3 "enhanced" risk includes the Dallas-Fort Worth metro area and Fort Smith, Arkansas.

A level 2 "slight" risk covers Spingfield, Missouri, Waco, Texas, and Wichita Falls, Texas.

The threat of tornadoes will be highest on Sunday across certain areas of Oklahoma and north Texas.
