American Airlines halts all flights in and out of DFW

DALLAS (AP) - High winds and heavy rains grounded hundreds of flights at Dallas-Fort Worth International Airport on Tuesday, and a control tower was briefly evacuated when a funnel cloud was spotted.

American Airlines canceled flights scheduled from 11 a.m. through the remainder of Tuesday - affecting some 700 departures and arrivals. More than 100 of the carrier's flights headed to D-FW were diverted, said airline spokesman Tim Wagner.

"The airlines are bringing planes back from the tarmac to the gate, and it's going to be a tough afternoon," airport spokesman Ken Capps said. "Everyone is working hard to keep passengers as comfortable as possible in the terminals."

Federal Aviation Adminstration officials evacuated the airport's west tower for about 15 minutes after seeing a funnel cloud over a highway. A funnel cloud was also spotted over Lake Lewisville, just north of the airport.

Staffing at the FAA's east tower was reduced for approximately 15 minutes because of strong winds.
