Hurricane Irma is barreling towards Florida and is expected to hit the southernmost part of the state before daybreak on Sunday.

The storm was downgraded to a category 4 Friday morning and is still considered “extremely dangerous” by the National Oceanic and Atmospheric Administration. Irma has been raging over the Caribbean for over a week, leaving 1 million people without power in Puerto Rico and killing at least 23. Friday’s 2pm NOAA advisory pegged Irma’s maximum sustained winds at 155 miles per hour. Irma has already broken all kinds of records, and its 185mph winds made Irma the strongest hurricane ever recorded in the Atlantic.

Irma has already hit St. Barts, St. Martin, Antigua, Anguilla, the British and US Virgin Islands, Puerto Rico, Barbuda, the northern coast of Hispaniola, and Turks and Caicos. The storm is just off the northeastern coast of Cuba, taking aim at south Florida.

Barbuda is now “barely habitable” according to a radio interview with Prime Minister Gaston Browne, who said more than half the population is now homeless. Officials on St. Martin report 95% of the island has been destroyed. The government of Haiti ordered all businesses and banks to shut down as the sotrm hit.

The National Weather Service (NWS) issued hurricane warnings in Florida for Jupiter Inlet south to Bonita Beach, the Florida Keys, Lake Okeechobee, and Florida Bay. In the Caribbean, hurricane warnings are in effect for the Bahamas; Turks and Caicos; the Cuban provinces of Camaguey, Ciego de Avila, Sancti Spiritus, and Villa Clara.

Governor Rick Scott issued a state of emergency for all counties in Florida, and Monroe County—where the Florida keys are located—and parts of Broward County and Miami-Dade County are under a Florida mandatory evacuation order.

The NWS forecasts Irma will remain a category 4 storm for the next few days, and will first hit the northern coast of Cuba near Santa Clara, then continue to directly through Florida as we head into the weekend.

Where will Hurricane Irma make landfall?

The forecasted path of the storm has shifted significantly since the beginning of the week. Here are the most recent (as of Friday 2:00pm eastern) storm-timing forecasts from the National Hurricane Center:

• Cuba: Irma is currently just off the northeastern coast, the eye likely won’t make landfall, but Santa Clara is expected to get hurricane-force winds Friday night into early Saturday morning
• Bahamas: The storm will likely travel west of the Bahamas Friday night; the eye is not expected to make landfall
• Florida Keys: Early Sunday
• Miami, FL: The eye will likely travel west of the city, which will experience hurricane-force winds early Sunday
• Orlando, FL: The eye will likely travel west of the city, which will experience hurricane-force winds on Sunday
• Gainesville, FL: Early Monday
• Atlanta, GA: Irma is forecast pass just west of the city on Tuesday, when it’s expected to downgrade to category 1 or a tropical storm
