Severe "monster storms" are expected to hit parts of Oklahoma, Texas, Kansas and Missouri on Tuesday. The Storm Prediction Center (SPC) warned the thunderstorms were "capable of damaging wind gusts" and tornadoes were expected to develop in the middle of the Mississippi Valley before moving south.

A tornado watch had been issued for portions of southern and east-central Oklahoma and northwestern Texas. Data from the SPC suggested the Oklahoma City metro area, southwest through to Lawton, Oklahoma and Wichita Falls, Texas was the region of primary concern.

Meanwhile, the area between Abilene and Midland, Texas, is at risk of receiving flood waters from central Oklahoma, to west and southwest Missouri and southeast Kansas. The main threats include possible tornadoes, scattered damaging wind gusts of up to 70 miles per hour and scattered large hail precipitation.

"A mixed mode of storms including a few supercells and bowing segments will continue to move east-northeastward across the region into the overnight. A few tornadoes remain a possibility, with damaging winds and isolated large hail a possibility," the SPC said in a statement.

"The tornado watch area is approximately along and 60 statute miles north and south of a line from 50 miles east southeast of Chandler, Oklahoma to 50 miles south southwest of Altus, Oklahoma."

The U.S. National Weather Service released flash flood warnings for Southern Oklahoma County and Northern Cleveland County, both located in central Oklahoma.

"Doppler radar indicated thunderstorms producing heavy rain across the warned area. Up to one and a half inches of rain have already fallen and an additional two inches is possible. Flash flooding is occurring or is imminent."

As a precaution, schools in parts of Oklahoma, including in the Oklahoma City metro area, were closed. Tinker Air Force Base, which is located approximately eight miles southwest of Oklahoma City, remained open but said on Monday it had moved aircraft to other military bases. In a statement posted on Facebook, the base's officials added "liberal leave" was recommended for military staff.

The weather warnings come after an outbreak of severe weather over the weekend, which made its presence felt on Oklahoma and northwest Texas through to Monday.

At least 50 tornado reports were submitted across the central and southern Plains on Monday. It was the first time since 2017 that the SPC had issued such a "high risk" warning for parts of Texas and Oklahoma.

According to AccuWeather Extreme Meteorologist Reed Timmer, Monday's storms were among the "more prolific severe weather setups we have seen in several years."
