As AccuWeather meteorologists had accurately forecast, severe thunderstorms have developed across parts of the northeastern United States. As these thunderstorms slowly move to the east over the coming hours, delays and cancellations can quickly increase at major airports, including Newark Liberty International Airport, John F. Kennedy International Airport and LaGuardia Airport.
“Pack your patience!” AccuWeather Chief Meteorologist Jon Porter warned. “People with flights scheduled at these airports into the evening should anticipate a challenging situation at the airports.”
“Additionally, delays and cancellations at these major hubs can quickly cascade to other parts of the county as airplanes and crews may be substantially delayed and not be in the correct place for later planned flights,” Porter added.
In addition to the risk of major delays at the airports, ground travel can be delayed and can even be dangerous in some areas, as thunderstorms can produce damaging wind, hail and flash flooding. AccuWeather forecasters urge motorists to avoid driving on roads covered by water as the depth of water can be deceiving and the speed with which it moves can add to the dangers. Even 6 inches of fast-flowing water is enough to move a car.
