The National Weather Service has issued a flash flood watch for Carroll County, along with other counties in northeast Oklahoma and northwest Arkansas, through Tuesday afternoon.

The national weather service in tulsa has expanded the flash flood watch to include portions of northwest Arkansas and northeast Oklahoma, including the following areas: in northwest Arkansas, Benton, Carroll, Madison and Washington; in northeast Oklahoma, Adair.

Widespread showers and thunderstorms will continue across northeast Oklahoma, spreading into southeast Oklahoma and northwest Arkansas this afternoon. Additional storms will develop further southwest and expand into another large thunderstorm complex that will track over the region tonight into Tuesday morning. An additional 2 to 3 inches of rain with isolated amounts of 5 to 7 inches will be possible through early Tuesday afternoon, creating the potential for dangerous flash flood conditions. Heavy rain is anticipated to be ongoing during the morning commute.

At this time it appears that the axis of heaviest rainfall will occur along Interstate 44 South to the Interstate 40 corridor.

In addition to flash flooding, river flooding will be possible across the watch area. Recent and expected rainfall will likely cause area rivers and streams to overflow their banks. Based on the latest 24 hour rainfall forecast, the following rivers have the potential to exceed flood stage by Tuesday afternoon: the Caney River from near Ramona to near Collinsville, Bird Creek from near Sperry to near Owasso, and Polecat Creek near Sapulpa. Additional rivers will be of concern should the axis of forecast rainfall shift either north or south.

Precautionary/preparedness actions

Be especially cautious at night when it is harder to recognize the dangers of flash floods. if flash flooding is observed, act quickly. Do not stay in areas subject to flooding when water begins to rise. Motorists should not drive through water of unknown depth. Take a different route to reach your destination or wait until the water recedes. Those traveling during the morning commute should check weather conditions before leaving home.

Persons with interests along rivers and streams in the watch area should remain informed of the latest weather and river information and be prepared to take action as necessary.

If you are in the watch area, keep informed and be ready for quick action if flash flooding is observed or if a warning is issued.
