Flash flood warnings remain in effect Wednesday for most of North Texas as Tropical Depression Hermine continues to drench the Metroplex, prompting evacuations, road and school closures as creeks and rivers begin to swell far beyond their banks in communities all across the Metroplex.
NBC DFW Weather watchers report as much as 9-inches of rain in parts of southern Tarrant County and 5-to-6-inches in northern Tarrant County. According to NBC DFW Meteorologist Samantha Davies, another 3-to-5 inches of rain is possible for North Texas.
Hermine lost steam and weakened into a tropical depression after it crossed into Texas. The remnants of the storm are expected to reach as far north as Oklahoma and Kansas.

Rain -- some of it heavy -- is expected for the rest of the week. But most major flooding problems are expected west of Fort Worth, said NBC DFW meteorologist David Finfrock. The heavy rains are expected to continue to move north. Dallas will probably only see light to moderate rain, with Fort Worth seeing more.

Just after 3:15 p.m., the NWS detected a developing tornado on radar near New Hope in Collin County. The storm followed a path from the Princeton area northwest toward Melissa. Despite the radar reports, no funnel clouds were ever reported by storm spotters.
And at 4:18 p.m., NWS meteorologists detected a tornado on radar in southeast Wise County five miles northeast of Rhome moving northwest at 20 mph. The warning expired at 4:45 p.m. with no reports of any touchdown.
