We're hearing reports of moderate to severe flooding north and east of Tulsa. If you're wondering whether you'll need an ark to complete your Fourth of July travel plans, you can ask NOAA.
The website for the Advanced Hydrological Prediction Service has a national map showing all active flood gauges and their current state. Purple means major flooding, red is moderate. Click on the national map and you'll see an area map, and you can then click on an individual gauge to see the flood level in recent days and the predicted level over the next few days. Here's the map for the Tulsa area.
The gauge for the Caney River at Bartlesville shows that the river has crested at 21.45 feet, more than 8 feet above flood stage, but is still about 6 feet shy of the record October 1986 flood. If you'd planned to visit the Kiddie Park, you might want to phone ahead.
Here's a map for NOAA's Arkansas-Red Basin River Forecast Center, which will give you a sense of the extent of flooding around Oklahoma and neighboring states. Not only is there some major flooding in southeastern Kansas and northeastern Oklahoma, but also in southwestern Oklahoma and Wichita Falls, just across the Red River in Texas.
The Oklahoma Highway Patrol posts road closings due to weather, or you can phone (405) 425-2385 or (888) 425-2385. There are a number of warnings and closings in Nowata, Craig, and Ottawa counties.
