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.
Flash flood watches for Tarrant, Dallas, Denton, Collin, Wise, Parker, Hood, Johnson and Ellis counties expire at 7 a.m. Thursday. Jack, Palo Pinto, Montague, Cooke, Grayson, Erath, Somervell, Hill, Bosque, Comanche and Hilton counties also have flash flood watches that expire at 7 a.m. Thursday.
The National Weather Service confirmed that a tornado touched down near the Tarrant-Johnson county lines, but officials said there were no reports of damage. A funnel cloud was reported shortly before 3 p.m. near Briar Oaks southeast of Burleson.
Tornado warnings issued Tuesday afternoon for Johnson, Tarrant, Wise and Collin counties expired with no reports of damage.
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.
Finfrock said tropical storms can drop out small, weak tornadoes with little warning. The tornadoes typically have winds up to 90 mph that fall into the F0 and F1 range. They can do damage, but they typically don't remain formed for very long.
The National Weather service issued a flood advisory for Dallas, Parker and Tarrant counties. Tornado watches for 13 North Texas counties including Collin, Hunt, Rockwall, Dallas, Kaufman, Tarrant, Denton, Parker Wise, Delta, Van Zandt, Hopkins and Rains counties expired at 8 p.m.
Widespread heavy rainfall is expected to continue through Tuesday and Wednesday as Hermine continues to push northward. The rainfall could cause street flooding or flash flooding with little to no warning.
