Flight delays and cancellations are growing across the East Coast's busiest airports Friday, after showers and thunderstorms continue to pound the Northeast part of the country.
In the Washington, D.C. area, two planes clipped each other while taxing at Dulles International Airport, but the incident luckily did not affect airport operations.
Already airports in New York City and Philadelphia are experiencing the worst of the slowdown: 154 flights canceled at LaGuardia, 72 in Philadelphia and 54 at JFK.
Inbound flights to Newark are delayed an average of about three hours, according to FlightAware.com, and 35 flights have been canceled.
Flights headed to JFK are delayed at their origin by about two-and-a-half hours, flights to nearby LaGuardia have two-hour delays, and arriving flights at Philadelphia International are delayed about 50 minutes, according to FlightAware.
Travel from the nation's capital is no better: Dulles International reported departure delays up to an hour-and-a-half. At 3:15 p.m. a Lufthansa Airbus A330 with 183 passengers en route to Frankfurt, Germany, clipped the tail of a Colgan Air turboprop flight operated by United Express and carrying 68 passengers.
Fire crews responded to the incident and no passengers were injured, but the Lufthansa plane sustained wing damage as did the Colgan aircraft's tail. Colgan Air said in a statement that the airline is investigating the incident and is working with FAA and the National Transportation Safety Board.
At Reagan National departures are delayed an average of 50 minutes and 31 flights have been canceled so far.
Detroit, Atlanta and Chicago are also seeing cancellations.
Isolated thunderstorms are expected to continue in New York City most of Friday, before forecasters say a potentially severe storm is expected to hit the area, NBC 4 New York reported. The severe weather could bring damaging winds, blinding downpours and intense cloud-to-ground lightning.
Forecasters say the wet weather is expect to continue into Saturday.
