Remnants of Tropical Depression Bill continues to slide north into Oklahoma.
News On 6 meteorologist Mike Grogan says as the low-pressure system moves northward Wednesday afternoon and evening heavy rain associated with the abundant tropical moisture will lead to major flooding south of Interstate 40. That rain will shift north of I-40 overnight.
Grogan says flash flooding is a major threat because the ground across eastern Oklahoma is already saturated. He says the greatest flooding threat will be Thursday morning as the center of the depression will be over southeast Oklahoma.
The Tulsa branch of the National Weather Services has issued a Flash Flood Warning until 1:30 Thursday morning for Okmulgee, Okfuskee, Muskogee, McIntosh and Creek counties.
News On 6 Chief Meteorologist said rain associated with this system is running about an inch an hour and anywhere between four to eight inches is expected.
Meyer said isolated areas could see upwards of 12 inches of water.
Several Oklahoma counties are also under a Flash Flood watch until Friday morning.
In addition, Mike Grogan says roads and highways in low-lying areas will quickly be covered in water making them impassible. He says as the depression moves into northwest Arkansas and southwest Missouri, the rain will taper off by Thursday evening into Friday morning.
