After slamming the South, Ida crossed the northeastern U.S. on September 1 as a tropical storm. Record rainfall caused flooding in the region. At least 18 people were killed.
The nearly 8.5 million residents of New York City were told to shelter at home. “We’re enduring an historic weather event tonight, with record-breaking rain . . . flooding, and dangerous conditions on our roads,” Bill de Blasio said. He’s the city’s mayor.
Tornadoes struck New Jersey. The storm caused hundreds of flights to be canceled at Newark Liberty International Airport. In Pennsylvania, highways were underwater.
Scientists say that powerful storms like Ida have become much more common as the planet has continued to warm.
