Heavy rain pummeled south Texas on Sunday, while in Vermont emergency crews restored power to homes after a late-season snow storm. NBC's Michelle Franzen reports.

Rescue teams Sunday found the body of a teenager believed to have drowned in powerful flood waters, raising the death toll from heavy rain that pummeled the San Antonio area to three, authorities told NBC News.

Police in Schertz, a city northeast of San Antonio, said Avram Adams, 18, was found early Sunday evening not far from where he had last been seen. They said he may have been tugged downstream by a massive flood surge Saturday.

Two people had already been confirmed dead, and 130 others were rescued from the wrath of the storms, which dumped more than a foot of rain on the city in 24 hours, sweeping cars and a city bus off main streets.

The majority of rescues were people trapped in their vehicles in low-lying areas of the city, San Antonio fire spokesman Christian Bove told NBC News.

Bove said a 29-year-old woman was trapped in her vehicle and tried to escape the rising water by climbing onto the car's roof. She was washed away, and her body was found down the road against a fence.

A woman in her mid-60s was found dead hours after her car was swept away in Leon Creek, Bove said. He said a rescue boat had just reached her car when the car rolled over, knocking the firefighters into the water. By the time they were able to get back into the boat, the car was submerged and they lost sight of it, Bove said.

Bove said dozens of homes suffered flood damage and part of the roof of an apartment building collapsed.

Flooding along the San Antonio River in Bexar County outside the city forced the evacuation of more than 60 people, county spokeswoman Laura Jesse said. She said at least 16 were rescued from vehicles but there were no reports of injuries or deaths in the county.

A small tornado touched down in the suburb of Live Oak, causing minor damage to homes, a hospital and a medical building, the National Weather Service confirmed.

Weather Channel meteorologist Nick Wiltgen said San Antonio received 12.16 inches of rain in the 24 hours that ended at 11 a.m. (noon ET) Saturday. That is just shy of the 24-hour record of 13.35 inches in October 1998.

Bove said the city was expecting more rain overnight.
