OKLAHOMA CITY — Flash flood watches are in effect across Oklahoma as more thunderstorms move into the state.
The National Weather Service says a slow moving storm system will bring several rounds of heavy rainfall to Oklahoma through the long Memorial Day holiday weekend. Forecasters say the rainfall is likely to worsen ongoing river flooding and lead to flash flooding in some areas.
Between 2 and 5 inches of rainfall with locally higher amounts are possible through Monday morning in western, central and southern Oklahoma. Rainfall amounts of 3 to 6 inches will be common in eastern Oklahoma, with locally higher amounts that may approach 10 inches.
Heavy rainfall has resulted in flood warnings for several waterways in the state, including the Washita River at Anadarko and the Little River near Tecumseh.
