Officials say the rain Saturday may have contributed to several wrecks throughout the day and one water rescue.
Editor's note: This article has been updated to include details about a water rescue.
Meteorologists predict that the region could see as much as 10 inches of rainfall for October by month’s end, and the rain is already believed to have contributed to multiple crashes and the need to a water rescue on Saturday. The weekend saw more than an inch-and-a-half as of midafternoon Saturday.
These storms followed what proved to be a wet start of fall, with September receiving more than 10 inches of rainfall — nearly three times the monthly average and significant flooding elsewhere in the state. Earlier this week, State Climatologist John Nielsen-Gammon said September likely will be among the wettest months on record for the state.
“There is still some light to moderate rain expected throughout the day and much more as we get into late Sunday through Tuesday,” Matt Bishop, a meteorologist with the National Weather Service’s Fort Worth office, said Saturday.
When combined with storms earlier in the month, Bishop said the region has received about 4.44 inches of rain, putting the area on course to surpass the monthly average of 5.29 inches. Bishop said current predictions call for nine to 10 inches of rain to fall over Sherman in October.
Officials with Sherman Fire-Rescue reported that the rain Saturday may have contributed to several wrecks throughout the day. At around 4 p.m. first responders received a call of a vehicle that had been flooded in Choctaw Creek.
Battalion Chief Bill Macon said the incident occurred on Old Luella Road, and the driver said he had driven across the roadway several times when it was flooded. However, on Saturday the water over the roadway was between three and four feet deep.
When first responders arrived with a swift water rescue boat, they found the driver sitting on top of the swamped truck. Macon said he isn’t certain if the driver left the roadway or if the truck was swept off into the creek.
After about 30 minutes, the driver was rescued, uninjured, using a rope and a life vest, Macon said.
The remains of Tropical Cyclone Sergio
Bishop said the current system different from recent cells in that it was progressive and moving. Rather than having a storm system stall over Texoma, Bishop said this current system is a result of an upper-level disturbance combining with the remains of Tropical Cyclone Sergio and the moisture it brought with it.
While there has been significant rain in Texoma, Bishop said areas south of the Dallas-Fort Worth Metroplex are seeing the heaviest rainfall. And areas along the Interstate 35 corridor from Denton south are seeing localized flooding, he said.
Bishop said the current line of storms is expected to continue through midweek, with chances for precipitation returning next weekend.
The recent rains have also raised some concern about flooding. Earlier this week, officials with the U.S. Army Corps of Engineers opened the floodgates of Denison Dan to release water downstream. Due to the size lake’s watershed — which is about the size of the state of Indiana — runoff from hard-hit areas is combining with local rainfall to put the lake into its flood control pool.
As of Saturday afternoon, the lake’s elevation stood at 624.15 feet, roughly 6.84 feet above normal for this time of the year; this puts the flood control pool at 25.15 percent full. The spillway is at 640 feet.
In an update issued Friday, the USACE forecast that the lake levels would reach 627.9 feet by Oct. 25 based on current and expected inflow into the lake.
