Hurricane and Storm Surge Watches and Warnings

Life-threatening and historic storm surge is likely in parts of South Florida, according to the National Weather Service.

A storm surge warning has been issued from the South Santee River southward to the Jupiter Inlet and on the peninsula from North Miami Beach to the Ochlockonee River, including the Florida Keys and Tampa Bay.

In addition, hurricane and tropical storm watches and warnings have been issued.

Hurricane warnings now extend as far north as Fernandina Beach on the Atlantic side, and up to Indian Pass on the Gulf side, and well into southern Georgia. Included in the hurricane warnings are the Florida Keys, Naples, Ft. Myers, the Tampa/St. Petersburg metro, Miami, West Palm Beach, Tallahassee, Thomasville and Valdosta.

Hurricane warnings also continue for a portion of a north coast of Cuba. Hurricane warnings mean hurricane conditions are either occurring or expected to occur within 36 hours.

A hurricane watch is also in effect for the Georgia coast northward to Edisto Beach, South Carolina. A watch means hurricane conditions are possible within 48 hours.

Tropical storm warnings are in effect for the western Florida panhandle outside of the Pensacola metro area and along the Georgia and South Carolina coasts up to the South Santee River.

Current Storm Status

Current Storm Status

The highest cloud tops, corresponding to the most vigorous convection, are shown in the brightest red colors. Clustering, deep convection around the center is a sign of a healthy tropical cyclone.

The NWS office in Key West warned of “swaths of tornado-like damage” possible in the eyewall that is currently hammering the Lower Keys. Storm surge in Key West has already topped 2.5 feet and should rise as water continues to pile into the Keys around the eyewall of Irma.

A Weatherflow station at Smith Shoal Light, about 15 miles northwest of Key West, recorded a wind gust of 96 mph just after 5 a.m. An 89 mph gust was recorded at 7:16 a.m. at the NWS Office in Key West.

Several gusts from 60 to 70 mph were clocked in Miami and West Palm Beach, with trees downed, stop signs downed, and shutters ripped off on Ocean Drive in South Beach, according to NBC 6 Miami.

Other notable wind gusts so far:

  • Marathon Key: 88 mph
  • Deerfield Beach: 77 mph
  • Miami International Airport measured a wind gust of 75 mph – this site is located at 95 feet in elevation
  • Fort Lauderdale/Hollywood International Airport: 70 mph

Wind gusts from 40 to 50 mph have also spread north as far as the Georgia Coast. At least one tree was downed in St. Simons Island, Georgia, early Sunday.

An extensive area of heavy rainbands had already formed well north of the center of Irma over much of the Florida Peninsula, flirting with the Georgia Coast.

Over 10 inches of rain has already triggered flooding that shut down a stretch of U.S. 1 in Ft. Pierce, Florida, with water reportedly into at least one home and parked cars flooded.

NOAA’s Storm Prediction Center has issued a tornado watch valid until noon EDT for all of southern and east-central Florida. The watch area includes West Palm Beach, Miami, Key West, Fort Myers, Vero Beach and Melbourne.

Projected Path and Intensity

After raking through the Keys, Irma will next strike southwest Florida with Category 4 intensity Sunday.

At this intensity, small deviations in wind speed intensity will not significantly change impacts. A direct hit will be devastating.


Here’s a general overview of the timing for impacts from Irma.

Potential Impact Timing

  • Bahamas: Tropical storm conditions in parts of the northwest Bahamas at least through Sunday night
  • Cuba: Hurricane conditions along north-central Cuba coast through Sunday morning
  • Florida: Hurricane-force winds arrive in South Florida and the Florida Keys spread north up the peninsula Sunday through early Monday; improvement Monday from south to north
  • Georgia-Carolinas: Late Sunday-Monday, possibly lingering into early Tuesday in some areas
Projected Path

Projected Path

The red-shaded area denotes the potential path of the center of the tropical cyclone. Note that impacts (particularly heavy rain, high surf, coastal flooding) with any tropical cyclone may spread beyond its forecast path.

It is important to remember not to just focus on the forecast cone, as it does not take into account the large size of Irma, with dangerous impacts expected outside of the path of the center.

South Florida Forecast, Impacts

According to the latest National Hurricane Center’s forecast, the center of Irma will pass over the Florida Keys Sunday morning, then track toward the southwest coast or the west coast of Florida coast Sunday afternoon.

Forecast Storm-Surge Flooding

Forecast Storm-Surge Flooding

The following life-threatening water-level rises (storm surge) are possible in South Florida Sunday, according to the National Hurricane Center, if they occur at high tide:

  • Southwestern Florida from Cape Sable to Captiva: 10 to 15 feet
  • Captiva to Anna Maria Island: 6 to 10 feet
  • Card Sound Bridge through Cape Sable, including the Florida Keys: 5 to 10 feet
  • North Miami Beach to Card Sound Bridge, including Biscayne Bay: 3 to 5 feet
  • North of North Miami Beach: 1 to 2 feet

(INTERACTIVE: How Much Storm Surge May Occur)

PLEASE evacuate as instructed by local emergency managers if you’re in an area where storm surge is forecast. Water (storm surge, rainfall flooding) is what claims the large majority of lives in hurricanes.

Depending on the exact track of Irma, locations in the hurricane warning areas could see devastating to catastrophic impacts, including structural damage and widespread power and communication outages from high winds. The National Weather Service said that areas in the hurricane warning could be uninhabitable for weeks or months.

Hurricane-Force Wind Probabilities

Hurricane-Force Wind Probabilities

The shaded colors represent the probability of any one location experiencing hurricane-force winds from Irma in the next five days.

If that wasn’t enough, up to 25 inches of rain is possible. Here are the latest rainfall forecasts from the National Hurricane Center and the Weather Prediction Center:

  • The Florida Keys: 15 to 20 inches, with isolated 25-inch totals
  • Southern Florida Peninsula: 10 to 15 inches, with isolated 20-inch totals

Numerous tornadoes are likely along the southeast coast of Florida and over the Everglades, to the north and east of Irma’s eye. Numerous tornadoes and waterspouts were reported in south Florida on Saturday evening.

North Florida Forecast, Impacts

Irma’s center is expected to track up the Florida west coast later Sunday into Monday.

Dangerous water-level rises (storm surge) are also possible in north Florida, according to the National Hurricane Center, if they occur at high tide:

  • Anna Maria Island to Clearwater Beach, including Tampa Bay: 5 to 8 feet
  • Clearwater Beach to Ochlockonee River: 4 to 6 feet
  • South Santee Beach in South Carolina south to Fernandina Beach in northeast Florida: 4 to 6 feet
  • Fernandina Beach to North Miami Beach: 2 to 4 feet

Significant inland wind damage and rainfall flooding could occur in parts of north and central Florida, given Irma’s large and growing size.

Locally heavy rainfall is expected, with up to 20 inches possible, based on the latest rainfall forecasts from the National Hurricane Center and the Weather Prediction Center:

  • North Florida Peninsula: 8 to 12 inches, with isolated 16-inch totals
  • Eastern Florida Panhandle: 3 to 6 inches, with isolated 10-inch totals
Rainfall Forecast

Rainfall Forecast

Localized higher amounts are possible.

The threat for tornadoes increases along the East Coast, especially to the north and east of where the center passes beginning late Sunday into early Monday.

Georgia, Carolinas Forecast, Impacts

The center of Irma is then expected to track into Georgia Monday afternoon into Tuesday.

Dangerous water-level rises (storm surge) of 4 to 6 feet are also possible from South Santee River, South Carolina, to Fernandina Beach, Florida, according to the National Hurricane Center, if they occur at high tide.

Significant inland wind damage and rainfall flooding could occur in parts of Georgia and the Carolinas, as well.

A forecast model developed by Seth Guikema (University of Michigan), Steven Quiring (Ohio State University) and Brent McRoberts (Texas A&M) predicted over 2-million customers could be without power from Florida to east Tennessee from Irma’s widespread winds.

Potential Power Outages

Dangerous surf and coastal flooding will likely exist throughout the southeastern U.S. coastline even well away from Irma’s center this weekend into early next week.

In fact, the National Weather Service in Charleston, South Carolina, said that record tide levels, topping those during Hurricane Matthew, are possible at Ft. Pulaski, Georgia, and storm surge at Charleston Harbor Monday could top that seen from Matthew, exceeded only by Hurricane Hugo in 1989.

Heavy rainfall is expected to spread across the Southeast. Here are the latest rainfall forecasts from the National Hurricane Center and the Weather Prediction Center:

  • Southeast Georgia: 8 to 12 inches, with isolated 16-inch totals
  • Rest of Georgia, southern and western South Carolina, western North Carolina: 3 to 6 inches, with isolated 10-inch totals
  • Eastern Alabama and southern Tennessee: 2 to 5 inches

Isolated tornadoes will be a concern into early next week.

Cuba, Bahamas Forecast

Hurricane conditions are expected to persist in portions of northern Cuba Sunday.

Dangerous water-level rises (storm surge) of 5 to 10 feet remain possible, according to the National Hurricane Center, if they occur at high tide.

Heavy rainfall is also expected. Here are the latest rainfall forecasts from the National Hurricane Center and the Weather Prediction Center:

  • Western Cuba: 3 to 6 inches, with isolated 10-inch totals
  • Western Bahamas: additional 2 to 4 inches, with isolated-6 inch totals

Recap: Leeward Islands Battered

The Leeward Islands were pounded by Irma late Tuesday into Wednesday.

Irma’s 185-mph winds made it the strongest hurricane to strike the Leeward Islands region, according to Dr. Phil Klotzbach, a tropical scientist at Colorado State University. That beat out the Okeechobee Hurricane (1928) and David (1979), which both had 160-mph winds at their peak in the Leeward Islands.

Irma first passed over Barbuda, an island of 1,600 residents, with gusts of at least 155 mph overnight into Wednesday morning. A storm surge of about eight feet was also recorded.

Early Wednesday morning, the eye of Irma then moved over St. Martin, St. Barthelemy and near Anguilla, where sustained winds of 117 mph were measured.

In addition, a 111-mph gust was reported on Culebra.

Irma made landfall as a Category 5 hurricane late Friday night along the Camaguey Archipelago of Cuba. This is the first landfall of a Category 5 hurricane in Cuba since 1924, based on NOAA’s historical hurricane tracks database. In Ciego de Avila, Cuba, Saturday morning, a wind gust to 159 mph was reported.

Damaged buildings and fallen trees litter the roads of downtown Marigot, on the island of St. Martin.


  1. I have been watching Channel 9 Orlando and watching the female reporter down at Merrit Island there at the mobile home park at the river, and oh my gosh, that is frightening. I think Merrit Island is between the Indian River and the Banana River, and I don’t know which river that is, that the mobile park is along, but the river water is up in their yards, at their front door now, and it is low tide! It is blowing the reporter’s jacket violently. She is dragging a microphone cord around in the standing water. Rotation is being reported there now in Merrit Island and Titusville. I am watching the damage coming in, and it is freaking me out. Especially the tree videoed falling and being uprooted. I think we may be in for it! They say we are on the “dirty side” of the hurricane. I have been on Merrit Island before and out in the river there too, but I wouldn’t think of staying there during a major hurricane.

  2. Oh no, I am now watching all these trees downed, and debris all over the yards, thinking it was from south Florida, but no, it was from Winter Springs in Seminole County! A tornado! How scary is that???

  3. This is weird. We have free tv, no cable, and we usually don’t pick up channel 9 very good when the weather is clear and sunny. Today it is pouring rain and windy and we are picking up channel 9 so good, and clear. It doesn’t make sense.

  4. Okay this is crazy. There are some men out playing golf in the rain now at the Winter Park Golf Club, and some boys on boogie boards skidding across the golf course grass where the water stands in puddles. That is wanting to play golf really bad!

  5. They were showing earlier today on the color- coded weather map that it is not good to see the green area and the red area come together, as that indicates rotation or circulation that can turn into a tornado. Save the pretty red and green colors coming together for a nice Christmas card, I don’t want to see that color scheme today on the weather map, especially near Apopka!

  6. It sure was rough a little earlier! It seems to be calmer right now for some odd reason. It must be the bands. Honestly, I thought the trees were going over! It seemed like our windows were going to break. I heard this loud boom, and told my husband,” oh the tree blew over in the front” but it wasn’t the tree, it was the transformer up the street that blew, and it was loud. I’m surprised we still have power. Our power keeps going on and off. My dog is petrified. I think it is coming this way! God help us! If it is this bad now what is it going to be then? Everything may come down if it moves this way!…..the weatherman says if you are near it ( the eye) you’ll hear it, meaning the roar. The hard core winds, the front, or the eye… is moving in the direction of Orange County Florida, the western section, theme park attraction area, Windemere, Clermont, Lake Apopka, and then north of Lake Apopka!!!!!!!!!!

  7. 2:00 am Apopka, that is when the main event will be here, the hard core eye, the worst of the worst! It will pass over Lake Apopka, then go over Apopka. About 2 and a half hours or so from now. Brace yourselves, as who knows what is coming! I have been fairly calm all night but not now! Too much excitement for me. I just pray that we all survive, and that these trees here don’t fall on our house, or that our roof doesn’t fly off. Once it gets here, I think they said the worst part will last for about 30 minutes. That is a long time!

  8. It will be 9-11 after midnight. That is strangely ironic. The Villages are going to be directly in the path. Man, the wind is getting louder outside already. Things had calmed down, but are getting wild again. The lights are flickering once again. I will be sooooo glad when this ordeal is over, and I don’t want to see Jose come this way either.

  9. I am looking at the red areas and that could spawn tornados. We sure don’t want that. Things are so crazy we may even get sharknados……LOL Sorry.

  10. Hey, I sure hope none of us gets injured in this craziness, because apparently 911 doesn’t want you to call them, and the hospitals don’t want you either.

  11. How about those low- lives that decided to loot, out near the Mall of Millenia, at a sporting good store, Academy Sports. Opportunity knocked, and they answered. Cops got 2 of them. Good! I bet they were after high priced sneakers and licensed trademarked sports clothing to sell on the streets.

  12. Yep, if you need help, you will just be SOL because the governor has already said that no one is coming to rescue you during the worst of the hurricane. How comforting that thought is with the eye on the way here. Thanks a lot Gov……..
