A flight from Detroit made a safe landing at New York's LaGuardia Airport this morning after it was struck two times by lightning.
The American Eagle Flight 4563 was hit as it approached the airport during a large thunderstorm.
American Airlines spokesman Matt Miller said the captain declared an emergency as a precaution but it landed safely.
A maintenance team inspected the Embraer 135 aircraft. It was carrying 20 passengers and three crew members.
Airplanes usually travel above bad weather, but they get struck by lightning at least once a year.
"It is routine for an aircraft to land as soon as possible after a strike, but this is a precautionary measure," Professor Manu Haddad of Cardiff University's Morgan Botti Laboratory said. "Lightning is extremely hot, up to 30,000 degrees celsius. The typical damage is a scorch mark where the point of contact was, usually a wing-tip. The plane's electronics are well shielded these days."
The thunderstorm comes as many rainstorms hover around the Tristate area today. The rain has been so heavy at times that certain roads have become blocked.
In the morning, a Flash Flood Warning was in effect for New York City, Staten Island and Brooklyn as more than two inches of rain fell.
Drivers were told to take precautions and not enter water on the roadway.
