Irma: Florida impact almost certain; 175 mph winds – 3 pm Update

Supercomputers are still struggling to nail down the path of Category 5 Hurricane Irma leaving forecasters with multiple possibilities for the storm’s track and intensity as she nears the Florida Straights and the U.S. Southeastern coast. The storm was supposed to begin weakening more than 36 hours ago and has only now dropped to 175 mph.

Hurricane Irma’s Current Position and Track

That national weather service is currently forecasting landfall in southeastern Florida somewhere near the West Palm Beach area with a second landfall close to the Georgia-South Carolina border and the latest computer models show a similar track.

1400 AST/EDT (1800 UTC) Update from National Weather Service

  • Location: 20.7 N, 70.4 W – 72 miles southeast of Turks and Caicos
  • Strength: 175 mph max sustained winds (Very Strong Category 5)
  • Movement: WNW (290 deg.) at 16 mph
  • Pressure: 922 mb, 1 mb increase from last update which may indicate weakening

Irma is a very strong category five storm but is expected to weaken to a category four hurricane with 145 mph winds over the next 72 hours as it skirts the Dominican Republic and the Bahamas before approaching Florida.

Catastrophic damage will occur: A high percentage of framed homes will be destroyed, with total roof failure and wall collapse. Fallen trees and power poles will isolate residential areas. Power outages will last for weeks to possibly months. Most of the area will be uninhabitable for weeks or months.

Hurricane-force winds extend outward up to 60 miles (95 km) from the center and tropical-storm-force winds extend outward up to 185 miles (295 km).

Computer Models for Hurricane Irma

Computer models are widely varied as to Irma’s track through the Florida straights and near Florida. The timing of the storm’s northward turn is uncertain which could lead to a Florida landfall or hold Irma to the east of Florida. Secondarily, a Georgia or South Carolina landfall is almost certain.

Early cycle model consensus has returned to a track we last saw two days ago where the storm makes landfall south of Miami and travels up the Florida peninsula and into Georgia.

The late cycle model consensus has also moved westward showing a direct hit to Miami and staying on shore across more of southeast Florida than the NWS forecast.

The intensity models are almost all showing a steadily weakening storm as it approaches Florida.

Florida has declared a state of emergency and evacuations are ordered for the Florida Keys and a portion of Broward County. If the forecast continues to show Miami as the landfall location, expect more evacuation orders for southeast Florida.

Broward County Mayor Barbara Sharief said Wednesday that mandatory evacuations have been issued starting at noon Thursday for all residents east of U.S. Route 1, known as Federal Highway, including all barrier islands.

Miami-Dade County is evacuating those with special needs.

Floridians should start preparing now to either shelter-in-place or evacuate. If Irma tracks towards Florida, additional evacuations will likely be posted. Don’t wait until the last minute and please listen to local authorities for instructions.


Georgia has declared a state of emergency. No evacuation orders are in place. Atlanta area hotels have begun filling up as those in low-lying areas seek shelter.

South Carolina

South Carolina has declared a state of emergency, no evacuation orders are in place.

Governor Henry McMaster said that residents should start preparations for Irma as if she were coming tomorrow.

“Now is the time to prepare,” McMaster warned during a news conference at the S.C. Emergency Management Division headquarters on Wednesday. “When it’s too late, it’s too late and that’s when we have a lot sadness.”

North Carolina

Gov. Roy Cooper has declared a state of emergency for North Carolina. No evacuations have been ordered.

What to Expect from Hurricane Irma

STORM SURGE: The combination of a dangerous storm surge and the tide will cause normally dry areas near the coast to be flooded by rising waters moving inland from the shoreline. The water is expected to reach the following HEIGHTS ABOVE GROUND if the peak surge occurs at the time of high tide…

Jupiter Inlet to Bonita Beach, including Florida Keys…5 to 10 ft

The deepest water will occur along the immediate coast in areas of onshore winds, where the surge will be accompanied by large and destructive waves. Surge-related flooding depends on the relative timing of the surge and the tidal cycle, and can vary greatly over short distances. For information specific to your area, please see products issued by your local National Weather Service forecast office.

The combination of a life-threatening storm surge and large breaking waves will raise water levels ABOVE NORMAL TIDE LEVELS by the following amounts within the hurricane warning area near and to the north of the center of Irma. Near the coast, the surge will be accompanied by large and destructive waves.

  • Turks and Caicos Islands…15 to 20 ft
  • Southeastern and central Bahamas…15 to 20 ft
  • Northwestern Bahamas…5 to 10 ft
  • Northern coast of the Dominican Republic…3 to 5 ft
  • Northern coast of Haiti and the Gulf of Gonave…1 to 3 ft
  • Northern coast of Cuba in the warning area…5 to 10 ft

Water levels around Puerto Rico should subside today.

WIND: Hurricane conditions are expected to begin within the hurricane warning area in the Dominican Republic and Haiti today. Hurricane conditions are expected to begin in the southeastern Bahamas and the Turks and Caicos Islands later today with tropical storm conditions expected within the next several hours. These conditions will spread into the central Bahamas by tonight or early Friday.

Hurricane and tropical storm conditions are possible within the watch area in Cuba by Friday. Tropical storm conditions are expected to begin within the warning area in Cuba tonight. Hurricane conditions are expected in the northwestern Bahamas Friday night and Saturday.

RAINFALL: Irma is expected to produce the following rain accumulations through Saturday evening:

  • Northeast Puerto Rico and the British and U.S. Virgin Islands… additional 2 to 4 inches, isolated 6 inches
  • Much of the Bahamas and Turks and Caicos…8 to 12 inches, isolated 20 inches
  • Andros Island and Bimini, Bahamas…12 to 16 inches, isolated 25 inches
  • Northern Dominican Republic and northern Haiti…4 to 10 inches, isolated 15 inches
  • Southern Dominican Republic and southern Haiti…2 to 5 inches
  • Eastern and central Cuba…4 to 10 inches, isolated 15 inches
  • Southeast Florida and the upper Florida Keys…8 to 12 inches, isolated 20 inches
  • Lower Florida Keys…2 to 5 inches

In all areas this rainfall may cause life-threatening flash floods and mudslides.

SURF: Swells generated by Irma are affecting the northern Leeward Islands, Puerto Rico, the Virgin Islands, the southeastern Bahamas, the Turks and Caicos Islands, the northern coast of the Dominican Republic, and should start affecting portions of the southeast coast of the United States later today and tonight. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
