At least 4 killed in Oklahoma tornado outbreak

After a tornado outbreak in Oklahoma overnight, at least four people have died, including an infant. Severe storms are threatening more twisters, heavy rain, and massive hail from Missouri to Texas on Sunday.

The National Weather Service reports that during the course of the night, numerous huge and extremely deadly tornadoes were recorded on the ground in various locations of Oklahoma.

According to Keli Cain, public communications director for the Oklahoma Department of Emergency Management and Homeland Security, there were two deaths in Holdenville and a third in Marietta on I-35.

At a press conference on Sunday, Governor Kevin Stitt of Oklahoma said that a fourth death had occurred in the severely damaged town of Sulphur in Murray County.

Stitt added that around 30 people were injured in Sulphur and their conditions are unknown.

Several counties reported floods, downed power lines and trees, injuries, and property damage on Saturday night, according to the Oklahoma Department of Emergency Management. Early on Sunday, it was unclear how much damage had been done.

The meteorological service said that Sulphur, around 80 miles south of Oklahoma City, saw damage and casualties from what looks like could have been at least two strong tornadoes overnight, coinciding with the city's flood warnings.

From east Texas northward into the upper Mississippi River Valley, over 47 million people are at risk of severe weather on Sunday. Communities in Nebraska and Iowa are already assessing the damage that the storms have already caused.

As storms move eastward across the southern Plains, cities including Wichita and Topeka in Kansas, Dallas and Austin in Texas, Oklahoma City and Tulsa in Oklahoma, and the Kansas City metropolitan region might see powerful tornadoes.

Storms are bringing significant rains along with tornadoes, which could make the situation even more dangerous.

Until Sunday morning, the meteorological service in Texas issued flash flood warnings for several counties, including Tarrant, Dallas, Johnson, and Parker. In these places, at least two to four inches of rain had already fallen.

The threat of a severe storm on Sunday was upgraded by the Storm Prediction Center to a category 3 of 5, affecting areas such as Shreveport, Little Rock, and Springfield in southern Missouri and eastern Texas. A level 2 of 5 severe storm threat is in effect for communities in southern Iowa and southeast Texas.

Unsettled weather is expected to continue across the midsection of the country into Monday.

The National Weather Service stated that "in addition to the severe weather, intense rainfall rates are expected to accompany these thunderstorms at times, leading to a moderate to locally high potential of flash flooding."
