Oklahoma flooding has killed a woman and a child, police say, as the region has been hit by severe storms this weekend.

A slow-moving, active storm system brought heavy rain, large hail and tornadoes to parts of Texas and Oklahoma and left three people dead as severe weather warnings Sunday continue to threaten parts of the south-central and Midwest U.

Two people died after their vehicle was trapped in floodwaters. Hail and strong winds were possible in parts of Arkansas, Missouri and Oklahoma on Sunday, forecasters said.
