Showers and thunderstorms flooded roads, damaged buildings and knocked out power Monday as a strong weather system swept across North Texas. The rainy weather was blamed for at least one death and caused numerous accidents and traffic delays in the Dallas-Fort Worth area.

An unidentified man in Denton was killed when he lost control of his car and slid into the path of an oncoming semi-truck, authorities said. The driver appeared to be driving too fast on the rain-slickened roads, Denton police spokesman Jim Bryan said.

About 35 miles northeast of Dallas in Farmersville, there were minor injuries - including a 15-year-old girl who was taken to an area hospital complaining of back pain - after a pickup hydroplaned into a school bus on U.S. 380.

Authorities said the westbound truck slid into the rear-wheel of an eastbound Farmersville school bus with 20 students aboard. The impact knocked the bus into a roadside ditch and onto its side.

In Dallas, a stretch of roadway under busy Interstate 635 submerged several vehicles and nearby soccer fields. One person had to be rescued from the flooded crossing but was not injured, authorities said.

Electricity was out for as many as 20,000 Dallas-Fort Worth customers, according to Oncor Electric Delivery.

Winds associated with the storms also blew off the roof of a warehouse in Dallas, as well as a vacant building in the Fort Worth suburb of Haltom City. There were no injuries in either incident.

The storms were caused by a cold front rolling eastward across the region. More rain was possible in the evening before subsiding Tuesday, weather officials said.
