Florida utility officials say more than 1 million customers have lost power as Hurricane Irma hits the state.
Florida Power & Light Company said that nearly 1.1 million customers statewide were without power Sunday morning.
About 574,000 of those outages were in Miami-Dade County, while there were 360,000 in Broward and nearly 136,000 in Palm Beach County.
The massive storm made landfall in the Florida Keys, and its centre was forecast to move up the state's Gulf Coast. But the effects are being felt far from the centre because of Irma's size.
The U.S. National Hurricane Center in Miami said the centre of the massive hurricane made landfall on Cudjoe Key in the lower Florida Keys at 9:10 a.m.
Its top sustained winds are 130 mph (215 km/h).
