A Southwest 737-700 slid off the runway at Chicago's Midway Airport during landing this afternoon.
Initial reports say that none of the 134 passengers or five crew were harmed; damage to the aircraft is unknown at this time but none was immediately evident in photographs of the scene.
Initial reports said Southwest flight 1919 (N799SW) from Denver International airport approached and landed on Midway's runway 13C at approximately 1:33pm CDT during crosswind conditions and heavy rain.
Southwest Airlines says that passengers were deplaned and bussed to the terminal.
"The airline is making outreach to each customer onboard the flight to refund their roundtrip and issue them two complimentary roundtrip passes as a gesture of goodwill," the carrier says.
NTSB released a statement confirming the incident, and declared its intent to secure the cockpit voice and flight data recorders and interview the pilots.
