Irma was downgraded to a tropical storm Monday morning and a tropical depression Monday night, but the storm was still powerful. As Irma left Florida, where officials estimated more than half of residents are without power, it brought rain to the entire state of Georgia and storm surge to cities on the Atlantic coast.

Irma made its first U.S. landfall at Cudjoe Key, just east of Key West, at 9:10 a.m. The storm was Category 4 with 130 mile per hour winds at the time. Its mainland landfall, as a Category 3 storm, came about six hours later near the beach town of Marco Island, just south of Naples on Florida’s west coast. Then storm slowly made its way north from there, bringing storm surges and heavy rain to Sarasota and the Tampa Bay area.

On Saturday, Irma skimmed the north coast of Cuba, swamping seaside towns. The storm’s peak winds eased down to 120 miles per hour before it regained strength over the warm waters of the Straits of Florida between Cuba and the Florida Keys. Irma began a gradual turn to the north late in the day, bringing the first bands of rain and high winds to South Florida

Irma spent Friday moving between the north coast of Cuba and the Bahamas, alternating between Category 5 and Category 4 as the larger island caused the storm to weaken. It had 160 mile per hour winds when it made landfall on Cuba’s Camaguey Archipelago late Friday night, becoming the first Category 5 storm to strike the nation since 1924.

Irma passed north of the Dominican Republic and Haiti, causing widespread flooding, before hitting Turks and Caicos and the southernmost islands of The Bahamas. These smaller islands suffered devastating damage.

Irma became the first hurricane in the satellite era to maintain Category 5 intensity for three consecutive days, although it began to lose strength in the evening. Updated models put its most likely path on a collision course with Florida.

The storm made its first landfall, passing directly over the Caribbean island of Barbuda overnight. Nearly every building on Barbuda was damaged, and much of the island’s 1,600 residents were left homeless. Irma continued west over Anguilla, St. Martin, St. Barts and both the British and U.S. Virgin Islands. Damage was catastrophic: Up to 90 percent of the buildings on some of the islands were damaged or destroyed.

The storm then brushed the northern coast of Puerto Rico, leaving one million residents without power but sparing the island the brunt of the storm. At least 25 deaths were reported throughout the Caribbean.

While approaching the Caribbean, Irma was upgraded to a Category 5 hurricane. Its maximum sustained winds of 185 mph made it one of the most powerful Atlantic hurricanes on record, with wind speeds comparable to Hurricane Andrew (1992) but covering a much larger area.
