HOUSTON (AP) — The Latest on heavy rains and flooding in the Houston area (all times local):
A county judge says four people have died in flooding caused by heavy rainfall in the Houston area.
Harris County Judge Ed Emmett says two people died in a vehicle that ignored barricades at a freeway underpass. He says traffic cameras recorded the vehicle going around the blockade and head into the water. The vehicle didn't make it through.
Two deaths reported earlier Monday included one man found inside a truck that that drove into high water on a freeway service road.
Harris County Precinct Sgt. Herbert Martinez says crews monitoring the high water on the road saw the man in the 18-wheeler truck drive directly into the water. He says it's possible the driver may have suffered some kind of medical emergency.
Another man, identified only as a contractor working for the city's airport system, also was found dead in a submerged vehicle not far from Houston Intercontinental Airport.
Texas Gov. Greg Abbott says some taxpayers affected by severe rain and flooding will qualify for an extension to file their federal tax returns that were due at midnight.
Abbott said Monday that his office had been in contact with the IRS about pushing the tax filing deadline for those in areas inundated by heavy downpours. More than a foot of rain dumped on parts of Houston and knocked out power to thousands of residents.
Abbott says more than half of the state remains under flood warnings. He says first responders have made more than 1,000 water rescues across Texas.
Abbott has declared a state disaster declaration for nine counties and said more will likely be added to the list.
Authorities say the body of a man has been found inside a truck that drove into high water on a Houston freeway service road.
The victim could be the second fatality linked to flooding from severe rains that began in Southeast Texas late Sunday night.
Harris County Precinct 5 Sgt. Herbert Martinez says crews monitoring the high water on the road saw the man in the 18-wheeler truck drive directly into the water. He says it's possible the driver may have suffered some kind of medical emergency.
Officials also were trying to determine if the storm was responsible for the death of a contractor working for the city's airport system whose body was found in a submerged vehicle.
Harris County sheriff's deputies have saved several horses from drowning as a Houston-area stable was inundated by floodwaters.
Sheriff's spokesman Ryan Sullivan says deputies used boats Monday to reach the horses, including some tethered animals that had to be cut free.
Sullivan says the horses from Cypress Trails were guided to land, for loading into livestock trailers and transport away from the flood scene. He had no immediate information on the fate of other horses seen struggling in water up to their necks in the area near Cypress Creek.
A message left with the owner of the stable, Cypress Trails, wasn't immediately returned Monday.
The stables are just north of George Bush Intercontinental Airport in an area where some nearby roads flooded Monday after heavy rain.
Houston Mayor Sylvester Turner says officials are trying to determine if the body of a person found in a vehicle submerged in water is a storm-related death.
Turner says the person is believed to be a contractor working for the city's airport system but authorities don't have enough information to confirm the cause of death.
The fatality would be the first related to flooding that's inundated hundreds of homes and roads in and around Houston. Some areas have received more than a foot of rain since Sunday night.
The mayor said at a midday briefing that the heavy rainfall has moved to the south and that the city is anticipating only about another half-inch the rest of the day.

The fate of the horses wasn't immediately known.

In the incident captured on video Monday (http://abc13.co/1S5l5VC ), KTRK reporter Steve Campion yells, "Dude, you've got to get out of the car!"
The man opens the passenger door and crawls out into the water as the reporter yells: "Leave the car! Swim!"

As the car slowly sinks under water, the driver tells Campion that he's OK and that he didn't think the water was so deep.
