Even though the flood gates were open, the water flowed over the dam due to the "tropical storm" remnants of Hurricane Erin. Note the fence being washed away along the sidewalk.

Weather Post From Central Oklahoma

September 6, 2007

 

The National Weather Service said remnants of Hurricane Henriette and a cold front are on track to merge over the state on Friday and possibly dump a lot of water on the region before moving east.

Southwestern Oklahoma received a taste of things to come Thursday evening, when severe thunderstorms moved into the area from the Texas Panhandle. A severe thunderstorm warning was issued for Beckham, Greer, Harmon and Washita counties for storms packing 65-mph winds and nickel-sized hail.

Elsewhere, skies were partly cloudy and temperatures ranged from 88 degrees in Muskogee to a blistering 102 degrees in Guymon. The mercury peaked at 91 degrees in Bartlesville and Tulsa and hit 92 degrees in Oklahoma City and Ponca City, forecasters said.

The heavy rain makes flooding and flash-flooding a real possibility over the weekend, forecasters said, and another approaching storm system expected by Monday could exacerbate the situation.

Skies should be mostly cloudy through Saturday with thunderstorms likely Friday and Saturday. Highs should reach the 80s and 90s on Friday and cool into the 80s on Saturday. Lows should dip into the 60s and 70s both nights, according to weather service forecasts.

A chance of storms will linger into Sunday and Monday, with temperatures holding in the 80s both days and lows in the 50s and 60s expected.

Skies should turn partly cloudy by Tuesday, with temperatures peaking in the 70s and 80s before ranging from the upper 40s in the northwest to the lower 60s in the southeast.
