Synopsis
Hurricane Irma formed from an African Easterly Wave, more commonly known as tropical waves. It became a tropical storm on August thirtythursday nearly 420 miles west of the Cabo Verde Islands in the far eastern tropical Atlantic Sea, and quickly attained hurricane status on August 31st while still in the far eastern Atlantic about 650 miles west of the Cabo Verde Islands. Irma continued to gradually strengthen over the next several days equally it tracked more often than not westward across the tropical Atlantic.By the time Hurricane Irma struck Barbuda in the northern Leeward Islands effectually 2am on Wednesday, September 6th, it was a Category 5 hurricane with 185 mph winds. Five hours later, the eye of Irma moved over St. Martin, nonetheless with 185 mph winds, while the northern eyewall pounded Anguilla. That afternoon, Irma cut a path directly through the British Virgin Islands. Subsequently the southern eyewall raked St. Thomas, Puerto Rico was largely spared as the heart passed about 45 miles north of San Juan. Hurricane conditions did occur on Puerto Rico's northeastern declension. Nevertheless a Category five, Irma impacted portions of the Turks and Caicos Islands and the southeast Bahama islands. From Friday evening September 8thursday through Saturday afternoon September ixthursday, Irma moved forth the northern coast of Cuba. Interaction with land caused Irma to weaken from a Category v to a Category iii before it began to pull away from the northern coast of Republic of cuba belatedly Saturday afternoon.
On Sunday morning, September 10thursday, Irma strengthened to a Category 4 hurricane every bit it accelerated toward the Florida Keys. The center made landfall in Cudjoe Key as a 130 mph Category four at nine:10am. The heart of Irma then made landfall in Marco Isle at 3:35pm that afternoon as a Category 3 with 115 mph winds. The center moved into central Florida overnight and into northern Florida after on Monday equally it weakened.

The Story for South Floridians
S Floridians began paying very close attending to Irma's forecast up to a week or more prior to landfall in South Florida. From about 5 days before landfall onward, the NHC forecast was consistent on a threat to South Florida. Residents and visitors swarmed grocery stores, gas stations and department stores to stock upwardly on essential supplies. The skillful news was that nigh South Floridians took the threat from Irma seriously. The bad news was that grocery stores chop-chop ran out of nutrient and water, while almost gas stations had run out of fuel one to 2 days before Irma hit.
Many South Floridians joined those across the state in evacuating, becoming a large function of the estimated 6+ million people who were ordered to evacuate, plus those who decided to leave town despite not being in mandatory evacuation zones. Those who left early still encountered significant traffic jams upstate. Finding gas was challenging for many. Upon driving dwelling house later the storm, people realized that many roads had either heavy traffic or flooding, which lengthened travel time. Other Southward Floridians stayed for the hurricane. Some left the barrier islands to ride out the storm with relatives or friends in a non-evacuation zone.
Heavy tree and fence impairment was widespread. Equally a event, over 3-quarters of electrical service customers in South Florida lost ability, many for close to a week. For east declension metro areas of Miami-Dade, Broward and Palm Embankment Counties, almost 95% of the power was restored inside 1 week after the hurricane. In the western half of South Florida, including Collier, Hendry and Glades counties, over xc% of customers lost ability and for periods of over a week. Heaviest damage occurred in these western areas where some structural impairment was noted, along with flooding impairment from tempest surge and rainfall. In Southeast Florida, structural impairment was small and generally consisted of roof roofing textile and screened patios. While Irma'due south impacts in Due south Florida were pregnant, there is no doubt that a slightly stronger Irma and/or a slightly different path could have resulted in much more damage and loss of life and holding.

Storm Surge/Tide
Collier Canton:the maximum surveyed inundation value was viii feet at the Smallwood Shop in Chokoloskee, with 3-five feet across most of the island. In Everglades Metropolis, a maximum overflowing of half dozen anxiety occurred at the Everglades National Park Gulf Visitor Center, with 2-iv feet common across the town and equally loftier as 5 feet in a few areas. Surveys conducted by the United States Geological Survey (USGS) indicated 1-2 anxiety of overflowing as far inland as Tamiami Trail/US 41 between State Route 29 and Collier-Seminole State Park. in Goodland, about 5-6 feet of alluvion was surveyed at the waterfront, with inundation of iii-4 feet across town. Marco Island had 2-4 feet of inundation, mainly on the south and eastward parts of the island with inland penetration of less than a half-mile. Naples had 3-4 feet of inundation at the Gulf of United mexican states and Naples Bay waterfronts and extending less than a half-mile inland.
Data from a USGS rapid deployment tide gauge at the Tamiami Trail bridge over Naples Bay (prototype beneath) showed a rapid rise of 8 feet in just over 9 hours mainly on the back side of Irma during the afternoon and evening of September 10th. This rise would have likely been much greater and devastating had the middle of Irma tracked just a few miles farther west.
Miami-Dade County: an average of three-5 anxiety of inundation occurred along the Biscayne Bay shoreline from Homestead to Downtown Miami/Brickell and extending inland 1-2 blocks, with peak surveyed flood of slightly greater than 6 feet in isolated spots in Coconut Grove and Brickell. Inundation decreased north of Downtown Miami forth the Biscayne Bay shoreline, with values generally around 2-3 feet. Along the Atlantic oceanfront, including Key Biscayne and Miami Beach, inundation was by and large around ii-3 feet and confined to the immediate beachfront.
Broward and Palm Embankment Counties: maximum flood of slightly greater than 3 feet along the Broward County coastline from Hallandale Beach to Fort Lauderdale, bars to the beachfront with lesser inundation affecting adjacent streets inside 1-2 blocks of the beach. Due north of Fort Lauderdale through the Palm Beaches, overflowing was by and large ane-ii feet at the beachfront.

Current of air
Irma was the first major (Category 3 or higher) hurricane to make landfall in South Florida since Wilma of 2005. The highest current of air gust recorded on country in Due south Florida was 142 mph at a mesonet site near Naples Airport. The highest sustained current of air recorded was 112 mph by a spotter on Marco Island.
The map to the left is an analysis of maximum sustained winds (one-minute average) in Hurricane Irma conducted by NWS Miami. The analysis is a best approximate based on all available information. The map on the right is from the National Hurricane Eye Tropical Cyclone Report on Hurricane Irma (red- hurricane force, orange- 58-73 mph, xanthous 39-57 mph). Disclaimer: some locations may accept received winds slightly higher or slightly lower than shown, and does Non include short-duration wind gusts which were at least 20-30 mph higher than the 1-minute average sustained wind speed
Collier Canton: Sustained Category iii winds of 111-115 mph were likely confined to a very small area of the eye that touched Marco Island and the immediate coastline of Collier Canton, including Goodland and Cape Romano. Sustained Category ii winds (96-110 mph) probable extended farther inland into west-central Collier County in the eastern eye wall, including the Golden Gate Estates and Orangetree areas. All of the greater Naples area received hurricane force sustained winds, with Category 2 sustained winds likely affecting much of southern and eastern portions of Naples. Along the northern coast of Collier County to the north of Naples, sustained winds probable peaked at Category 1 strength. Farther to the northeast, Immokalee likely received Category ane sustained winds. Peak air current gusts in Collier County reached at least Category ii forcefulness (95-110 mph) over most areas, with top Category iii and 4 gusts (111-140 mph) in the eastern eye wall. In add-on, tempest surveys indicated the likelihood of mini-vortices in the eastern eye wall which led to small swaths of higher winds.
Glades and Hendry Counties: Sustained winds of Category i strength likely occurred over most of Glades and Hendry counties, with highest winds in the LaBelle and Felda areas. Wind in northeastern Glades County likely peaked at slightly below hurricane force. Height wind gusts of Category two force (95-110 mph) probable occurred in the LaBelle and Felda areas.
Miami-Dade County: Most of the populated areas of Miami-Dade County experienced sustained winds of strong tropical storm force (58-73 mph). Yet, in that location were a few areas that probable experienced sustained winds of Category 1 hurricane forcefulness. Sustained winds may take reached hurricane strength (around 75 mph) in portions of southern Key Biscayne. Although not explicitly shown on the map, it is possible that sustained winds briefly reached 75 mph within a mile of Biscayne Bay (east of Bayshore Bulldoze and east of Old Cutler Road) from Coconut Grove to Pinecrest to Palmetto Bay. However, more probable, sustained winds in that area peaked effectually lxx mph (just beneath hurricane force). Sustained winds likely reached the lower limits of Category ane strength in portions of Homestead, especially southern and western portions of Homestead, including Florida Metropolis and southern portions of The Redland. In coastal Miami-Dade County from Downtown Miami north, including Miami Beach, North Miami Beach, Little Republic of haiti, North Miami and Aventura, sustained winds likely peaked in the 65-70 mph range. Sustained winds probable but reached the 55-65 mph for the western and northern parts of the metro expanse (west of the Palmetto pike to Krome Avenue) including Due west Kendall, Doral and Miami Lakes. Nearly all of Miami-Dade County experienced peak current of air gusts of Category one forcefulness (80-95 mph).
Broward County: One hurricane force sustained air current of 76 mph was recorded in Broward Canton at the Seminole Tribe Headquarters in Hollywood, so Category 1 winds are analyzed to have occurred within ane mile of that location on our map. Elsewhere, sustained winds peaked in the 65-seventy mph range in coastal and metro portions of Broward Canton. Sustained winds were lower in western areas such as Weston, Tamarac and Coral Springs, where the winds probable peaked in the 55-65 mph range. Gusts in well-nigh of Broward County were in the Category 1/2 range (80-100 mph). Simply isolated spots had gusts over 100 mph, in the 100-110 mph range.
Palm Beach County: Sustained winds peaked in the 55-65 mph range over southern coastal areas and most of central Palm Embankment County. Stronger sustained winds - in the 65-70 mph range - were observed along the immediate coastline north of West Palm Embankment to Jupiter. Current of air gusts reached Category 1 strength (80-90 mph) county-wide.
Mainland Monroe County: All of Mainland Monroe County probable received sustained winds that peaked in the Category one range (74-95 mph).

Rainfall
Highest rainfall amounts occurred over inland portions of Collier County and western sections of Hendry and Glades counties where the eye of Irma passed. These areas received anywhere from 9-15 inches of rain, with estimates of up to 20 inches in the Felda expanse also as the Big Cypress National Preserve. Elsewhere, rainfall totals were mainly in the six-x inch range.
Rainfall amounts produced by Hurricane Irma in S Florida
Tornadoes
Five tornadoes were confirmed in Southward Florida in association with Irma – 1 in Miami-Dade County, 3 in Broward County and 1 in Collier County. The tornado in Collier County occurred 2 miles west of Ochopee where wooden power poles were damaged forth Tamiami Trail betwixt Ochopee and the SR-29 intersection. It was determined to be an EF-1.
