Heavy rains and high winds are hitting parts of Texas, causing flooding that has led to four deaths.

Authorities say weather was a factor last night when a sport utility vehicle plowed into a dump truck in Austin, killing three women.

Austin police say another woman died Sunday when a gust of wind caused the motorcycle she was a passenger on to hit a guardrail.

The National Weather Service has issued a tornado warning for parts of northern Texas. A severe storm there blew a home from its foundation, ripped the roof off at least one house and damaged two others.

And in western Texas authorities rescued a man stranded atop his minivan as raging floodwaters threatened to consume him.

Search and rescue teams throughout Texas are at a high state of readiness.
