CLAREMORE, Okla. – The body of a firefighter was found in a storm drain two hours after he went missing late Saturday night. 
 
 Claremore Fire crews responded near the intersection of Archer Dr. and Archer Ct. around 10:30 p.m. to help flooding victims of nearby duplexes. 
 
 About an hour after they arrived, one firefighter was believed to have stepped into rushing water, which swept him into a storm drain, according to fire officials. 
 
 The body of Claremore Firefighter Captain Jason Farley was found inside the storm drain around 1 a.m. Sunday, Fox23 reports. 
 
 Officials suspect Farley drowned, but a medical examiner will determine the cause of death. 
 
 A second firefighter, Zane James, attempted to save the Captain Farley, but reports say he was also knocked down by the rushing water and had to be rescued. 
 
 He suffered minor injuries. 
 
 Report a typo ||||| Daytime heating is helping fuel a resurgence in thunderstorm activity across the beleaguered Plains states on this Sunday afternoon, prompting two tornado watches and concerns for additional flash flooding in areas already hard-hit by up to a foot of rain since Saturday. 
 
 A destructive, catastrophic flash flood hit a stretch of the Blanco River in and near Wimberley, Texas overnight Saturday night into early Sunday morning, and has since moved downstream into the San Marcos River. Officials estimate that about 1,000 homes have been damaged or destroyed, and at least one person has died.

 Here are the latest reports of flooding and severe weather. 
 
 Across the Region 
 
 Several tornado watches have been issued in the central U.S. For a map of the latest watches, see the radar maps below the live blog. 
 
 Severe thunderstorms blew trees onto homes near Marshall, Texas, early Sunday afternoon. The storms damaged an 18-wheeler on nearby Interstate 20. 
 
 The National Weather Service confirms that a tornado struck the west side of Corpus Christi, Texas, around 1:30 a.m. local time. The agency has not finished its survey and has not yet assigned the damage a rating on the Enhanced Fujita Scale. 
 
 The Houston Fire Department responded to the partial collapse of an apartment complex on the city's southwest side early Sunday on Nairn St. Four people were injured, and 10 units sustained severe damage. The National Weather Service says a brief tornado is to blame for the damage, and has given a preliminary EF1 rating to the twister. 
 
 Lake Texoma is now flowing over the spillway at the Denison Dam, which impounds the Red River to form the lake. According to the U.S. Army Corps of Engineers, the lake was at 107 percent of its flood control capacity Sunday afternoon, meaning the lake was holding nearly 55 billion gallons more than its full flood-control pool of 1.62 trillion gallons. Lake Texoma is along the Texas-Oklahoma border north of Dallas. 
 
 Mandatory evacuations were issued for properties below the Lewis Creek Dam west of Willis, Texas, about 50 miles north-northwest of downtown Houston. These were ordered as a precaution given the potential for more heavy rain. A Red Cross shelter was opened at the Lone Star Community Center in Montgomery. 
 
 At least one swift-water rescue was performed early Sunday morning in Arlington, Texas, where a shopping center was also flooded. 
 
 A firefighter in Claremore, Oklahoma, died after he was swept away performing a water rescue in the city early Sunday. A few houses were flooded in the city. 
 
 Multiple high-water rescues were reported Sunday morning in Venus, Texas (Johnson County), in the south Dallas-Ft. Worth metroplex. Farther south, rescues were also performed in the cities of Uvalde, D'hanis and Yancy, Texas. 
 
 High water was reported on Interstate 20 in both directions near Carrier Parkway in Grand Prairie Sunday morning, west of downtown Dallas. Numerous roads remained closed as of early Sunday morning in Ellis County, Texas. Part of a block of county road 1418 near Covington, Texas was reported to be partially washed out Sunday morning. 
 
 Catastrophic Flash Flood near San Marcos, Texas 
 
 At least one man has died in San Marcos, Texas, as a result of the catastrophic flash flood that developed on the Blanco River late Saturday night before emptying into the San Marcos River Sunday morning. 
 
 The National Weather Service issued a flash flood emergency late Sunday morning for the San Marcos River from San Marcos to Luling, Texas. This included parts of southeastern Hays, western Caldwell and northern Guadalupe counties. San Marcos is a city of about 55,000 people between Austin and San Antonio. A surge of floodwater continues to roll downstream along the San Marcos River into Luling, Texas. 
 
 The San Marcos River is rising fast in Martindale and Luling, Texas. Palmetto State Park at Ottine is experiencing severe flooding with at least 6 feet of water in the pavilion building likely, based on Sunday afternoon's NWS river stage report. Much of the Luling Golf Course is likely to flood, and some of the lowest homes north and northeast of the golf course may flood depending on exactly how high the river gets. 
 
 A curfew has been declared beginning at 9 p.m. Sunday and ending at 7 a.m. Monday for the cities of San Marcos and Wimberley, Texas, as well as unincorporated areas of Hays County. 
 
 An estimated 1,000 homes have been flooded in Hays County, Texas. Some residents are still stranded in their homes, but officials said Sunday afternoon that there are no longer any people waiting on rooftops for rescue. Up to 12.32 inches of rain fell near Kendalia, Texas in this event. 
 
 The Blanco River at San Marcos, Texas, crested just over 43 feet early Sunday morning, a rise of over 31 feet since late Saturday night. That 31-foot surge in the river level included a rise of 17 feet in just 30 minutes. Water levels remain high this morning as the flood crest rolls downstream. 
 
 The Blanco River rose more than 33 feet in just 3 hours in Wimberley, Texas, reaching a level more than 27 feet above flood stage at 1 a.m. Sunday. This broke the all-time record crest from 1929 by nearly 7 feet, before the river gauge stopped reporting. Wimberley is about 25 miles southwest of Austin. Emergency management reported residents were trapped on rooftops due to the sudden rise in floodwaters. Officials opened shelters to house those forced from their homes by the swollen river.

 Claremore Fire Capt. Jason Farley drowned Saturday night while rescuing a woman and six children from dangerous flooding. 
 
 
 
 The flag is at half-staff at the fire station in honor of the 20-year veteran. FOX23 was there as people stopped by to place flags on the station lawn. 
 
 
 
 A chaplain is assisting firefighters as they deal with the loss. Many in the area have also found it hard to cope. 
 
 
 
 Farley was helping a rescue operation where water was rushing into a home during a young girl’s 5th birthday party. All of the children and one adult were rescued through a window but Farley was pushed into a storm drain where he drowned. 
 
 
 
 “He’s our hero. That’s for sure. It could have been our grandkids or my daughter. I pray for his family and the other firefighters. They’re like family to each other,” Steven Darnell said. 
 
 
 
 Darnell’s grandchild was rescued by Farley. 
 
 
 
 The support for Farley’s family and fellow firefighters has been huge as fire departments across the state shared their condolences through social media.

– Record rainfall wreaked havoc across a swath of the Plains and Midwest yesterday, causing flash floods in normally dry riverbeds, spawning tornadoes, and forcing at least 2,000 people in Texas from their homes. A firefighter in Oklahoma was swept to his death: Fox23 reports Claremore Fire Capt. Jason Farley, a 20-year veteran, helped rescue a woman and six children through the window of a flooded home where they were celebrating a girl's 5th birthday party. KFOR reports it's believed rushing water swept him into a storm drain during the rescue; he's thought to have drowned. Two other deaths were reported: A woman in Tulsa died in a traffic-related crash, and in Texas, a man's body was recovered from a flooded area along the Blanco River. That river rose 26 feet in just one hour and left piles of wreckage 20 feet high, authorities said. Weather.com calls the flash flooding "catastrophic" and reports that in Wimberley, Texas, the Blanco River broke a crest record set in 1929—by 7 feet. "It looks pretty bad out there," said Hays County emergency management coordinator, describing the destruction in Wimberley, a community that is part of a fast-growing corridor between Austin and San Antonio. "We do have whole streets with maybe one or two houses left on them and the rest are just slabs," she said. As many as 400 homes were destroyed in Wimberley, many of them washed away. This May is already the wettest on record for several cities in the southern Plains states, with days still to go and more rain on the way. So far this year, Oklahoma City has recorded 27.37 inches of rain. Last year the state's capital got only 4.29 inches.
