Hurricane Dorian is lashing Florida's northeast coast with tropical conditions, with dangerous winds and coastal flooding reported in the state as the deadly storm heads toward the U.S.

The big picture: Dorian was downgraded to a Category 2 storm on Tuesday, but the National Hurricane Center warns that it'll remain a powerful hurricane, and it's forecast to move near or over the Carolinas' coast Thursday through Friday morning. States of emergency have been declared in Florida, Georgia, South Carolina, North Carolina and Virginia. Mandatory evacuations had been taking place in the 5 states since the weekend, affecting millions of people, per ABC News
