With Florida already bracing for a hit from Hurricane Irma, which according to some models may attain "monster" Category 5 winds as it nears land prompting locals to store up on everything from water to food to gas and various other housing supplies, late on Monday afternoon Florida Gov. Rick Scott declared a state of emergency ahead of potential landfall, just hours after the governor of Puerto Rico did the same.

At roughly the same time, the NHC announced that Irma’s top sustained winds have reached 130mph (215 kph), which prompted an upgrade to a Category 4 storm for Irma. According to the latest update, Irma was moving west at 13mph, and was currently located about 490 miles east of Leeward Islands.

A hurricane warning was in effect for Antigua, Barbuda, Anguilla, Montserrat, St. Kitts, and Nevis, Saba, St. Eustatius, and Sint Maarten, Saint Martin and Saint Barthelemy.

Puerto Rico is expected to be hit at 2pm on Wednesday.

While some models suggest a small chance of (another) Gulf of Mexico hit:

Even more concerning, it now appears that despite hopes for a last minute course revision, Miami is smack in the middle of the latest hurricane path projections.

Which likely means that the preliminary panic which has gripped some Florida residents, is about to get worse. As we reported earlier, WPTV in Palm Beach reported that Shelves of water at several stores were nearly empty Sunday, even as Irma’s path remains uncertain. Hardware stores are also running out of tanks of gas and other supplies. One distressed shopper told WPTV that one Walmart had run out of bottled water.

There was nothing at Walmart," said Bianca Rodriguez of Palm Beach Gardens. "Not even like one thing of water.”

According to WPTV emergency officials recommend people have one gallon of water per person, per day for at least five days in the event of a hurricane. Florida Gov. Rick Scott warned that “disaster preparedness” should be a priority for every family in the potential path of the storm. One shopper said he bought the last remaining cases of bottled water at the Winn-Dixie in Palm Beach Gardens.

“Rodriguez found cases of bottled water at a Winn-Dixie on Military Trail in Palm Beach Gardens Sunday night.  ‘I lucked out. There’s only a couple left, but at least there was enough for me,’ said Rodriguez.”

A Home Depot in Royal Palm Beach on Monday morning posted a sign that said they were short of some hurricane supplies.

And while some stores have already run out of supplies, for most Florida residents it is not too late to take precautions.

Here, courtesy of Wunderground's Bob Henson, is the latest summary on the rapidly intensifying Hurricane Irma, whose threat for Cuba, Puerto Rica and Florida, is rising by the hour.

Threat Increasing for Cuba, Florida from Intensifying Irma

Dangerous Hurricane Irma was intensifying as it approached the northern Lesser Antilles Islands on Monday morning, and island residents in the path of Irma need to rush preparations to completion as the storm heads west-southwest at 14 mph. A NOAA hurricane hunter aircraft in the storm found that Irma’s central pressure was steadily dropping Monday morning, reaching 944 mb at 11 am EDT. Irma's top sustained winds are estimated at 120 mph, and winds may not yet have fully responded to this pressure drop. Update: Based on Hurricane Hunter measurements, NHC raised Irma's top sustained winds at 5:00 pm EDT to 130 mph, making it a Category 4 storm. Irma is expected to be a major Category 4 hurricane when it passes very close to the northern Lesser Antilles Islands on Tuesday, near Puerto Rico and the Virgin Islands on Wednesday, and the Turks and Caicos Islands and Hispaniola on Thursday. As of 5 pm EDT Monday, Hurricane Warnings are in effect for the northern Leeward Islands, and Hurricane Watches are up for the U.S. and British Virgin Islands and Puerto Rico.

Tropical storm-force winds are expected to begin affecting the east coast of Florida and the Florida Keys on Friday night (Figure 1 below). An evacuation decision for the Florida Keys may have to come as early as Tuesday, since the Keys require 3+ days to evacuate. As of 5 pm EDT, far southeast Florida, including Miami, was in the 5-day cone of uncertainty fo

Satellite images on Monday morning showed a very symmetric well-organized storm with solid spiral banding and a large eye. Irma had a respectable and improving upper-level outflow on all sides. Conditions were favorable for strengthening, with wind shear a low 5 – 10 knots. Sea surface temperatures (SSTs) along Irma's path have risen sharply over the past day, to 29°C (84°F), accompanied by a substantial increase in the total heat content of the ocean (Figure 2), giving the storm plenty of heat energy to fuel intensification. The surrounding atmosphere has been steadily moistening, as seen on precipitable water imagery, with a mid-level relative humidity near 55%, according to the 12Z Monday analysis from the SHIPS model.

Figure 1. Most likely arrival time of tropical-storm-force winds from Irma, as of the 11 am EDT Monday, September 4, 2017 advisory from NHC.

Intensity forecast for Irma

For the next five days, wind shear is predicted by SHIPS to remain very favorable for development—a low to moderate 5 – 15 knots. SSTs will be very warm, 29 – 30°C (84 – 86°F), accompanied by a high ocean heat content capable of fueling rapid intensification. Mid-level relative humidity is predicted to steadily rise, reaching 70% by the end of the week. We can expect one or more eyewall replacement cycles (ERCs) this week, which will act to temporarily weaken the hurricane by about 10 mph. On Monday morning, the hurricane hunters found that an ERC was likely in progress, and the current intensification cycle will likely pause late today, as a result.

Our most reliable intensity models--the HWRF, COAMPS-TC, LGEM, and DSHIPS--predicted in their Monday morning runs that Irma would peak as a Category 4 or 5 hurricane with 130 – 160 mph winds, and the official NHC forecast of a Category 4 hurricane when it passes by the islands this week looks reasonable. The only major impediment to Irma’s strength would appear to be interaction with land; a close pass or direct hit on Hispaniola or Cuba could potentially damage or destroy the hurricane’s inner core and knock it down to Category 2 or 3 strength.

Figure 2. Total ocean heat content (OHC) along the track of Hurricane Irma, at 2 am EDT Monday, September 4, 2017. Irma is expected to encounter OHC levels of 80 – 100 kilojoules per square centimeter as it passes the Lesser Antilles islands. OHC levels this high are known to be very favorable for rapid intensification, and are similar to what fueled Hurricane Harvey’s rapid intensification over the Gulf of Mexico during its approach to the Texas coast (Figure 3).

How strong could Irma get?

Several computer models have been confronting meteorologists with some eye-opening intensity forecasts for Hurricane Irma, especially for the period around next weekend, when Irma is currently predicted to be arcing northwest from the Eastern Bahamas. We cannot rule out the chance that Irma will reach Category 5 strength, but we can safely discount some of the most extreme model-generated intensities. The GFS global model and the new HMON regional hurricane model have consistently been deepening Irma to pressures below 900 millibars (mb). However, neither of these models fully incorporates the interaction between ocean and atmosphere that serves as a check on a hurricane’s peak strength. A better guide to how strong Irma might get is the HWRF regional hurricane model, which extends out to 126 hours (just over five days). The HWRF has proven to be our most reliable model-based intensity guidance in recent years. The 0Z and 6Z Monday operational runs of HWRF deepened Irma to the 920 – 930 mb range, suggesting Irma will be a very formidable hurricane, but not a mind-blowing all-time record-setter.

For historical context, the lowest hurricane-related pressure ever measured at the surface north of the Caribbean and east of Florida is 921 mb in the Bahamas Hurricane of 1932. Hurricane Hunter dropsondes found a surface pressure of 919 mb within Hurricane Gloria (1985). Such pressures can support a Category 4 or 5 hurricane, but the peak winds depend on the size of the hurricane. As hurricanes move poleward, they typically get bigger. In a larger hurricane, the pressure force from a given central pressure will extend over a larger area, meaning that the top sustained winds will probably be lower but that a larger area could experience high winds and storm surge. This was the case with Hurricane/Superstorm Sandy, which brought record-low surface pressures and record-high surge across a large area despite winds of marginal hurricane force at best when Sandy made landfall.

Potential impact on the Lesser Antilles, Virgin Islands, and Puerto Rico

Irma will assume a more westerly and west-northwesterly track over the next day, bringing the core of Irma just north of the Lesser Antilles, Virgin Islands, and Puerto Rico on Tuesday and Wednesday. Irma is a medium-sized hurricane, with tropical storm-force winds that extend out 140 miles from the center, and hurricane-force winds that extend out 35 miles from the center. Most of the islands along Irma’s path will be on the weaker left side, where maximum wind speeds 10 – 20 mph less than the peak winds of the storm can be expected.

The 11 am EDT Monday Wind Probability Forecast from NHC highlighted a number of islands that might be at risk of tropical storm-force or hurricane-force winds on Tuesday and Wednesday. The highest odds were for Barbuda and Saint Maarten, with a 93% chance of tropical-storm force winds and a 52 -54% chance of hurricane-force winds. For the Virgin Islands and Puerto Rico, a 56 – 82% chance of tropical-storm force winds was given, and a 18 – 38% chance of hurricane-force winds.

The 6Z Monday run of the HWRF model predicted that northern portions of the Dominican Republic and Haiti, as well as eastern portions of Cuba, may receive rains of 8 – 16” from Irma. These rains will be capable of causing life-threatening flooding and mudslides. The model also predicted heavy rains of 8 – 16” in the Turks and Caicos Islands and the southeastern Bahamas.

Long-range outlook for Irma

Computer model guidance on Irma’s future track made an important westward shift on Sunday night. Virtually all models—including our most reliable ones for hurricane track forecasts, the GFS, European, and UKMET—took Irma further west than prior model runs before an expected sharp turn to the north. This shift increases the chance that Irma will directly affect Hispaniola and especially Cuba, as discussed above. The shift also raises the odds for a U.S. landfall considerably, because Irma’s expected right turn toward the north would probably occur too late for Irma to miss the U.S. East Coast entirely. A strong upper-level trough will be moving well offshore by early next week, reducing the odds that Irma would be hauled out to sea.

Figures 4, 5, and 6 show the dramatic shift southwestward and its implications for landfall in three different configurations of ensemble models (GFS, Euro, and Euro high-probability). The 00Z Monday UKMET model, not shown, moves Irma along or near the north coasts of Puerto Rico, Hispaniola, and Cuba.

It is unclear exactly why the modeled track shifted so dramatically on Sunday night, but the Monday morning (12Z) GFS run is very consistent with this shift, lending support to it. One piece of the puzzle is that the first Hurricane Hunter observations on Irma, gathered Sunday afternoon, were fed into the 00Z Monday runs. A raft of additional new data will be gathered on Monday and fed into upcoming model runs. This includes observations around Irma’s environment from the NOAA Gulfstream-IV, as well as extra radiosonde launches (weather balloons) that will sample the upper atmosphere at midday Monday (18Z) from 21 locations across the central U.S., where the upper-level trough expected to move offshore late this week will be taking shape. The model runs from 00Z Tuesday will incorporate the new data, so this will give us a much better sense of the steering currents guiding Irma and how those may evolve over the next week.

Irma is still four days from any potential direct U.S. impacts, so there is plenty of time for residents along the East Coast and eastern Gulf Coast to make any standard preparations for hurricane season that haven’t yet been squared away. The Sunday night model runs suggest that the entire Florida peninsula will need to pay very close attention to Irma, but it remains possible that Irma will move further north along the East Coast, or it could enter the eastern Gulf of Mexico. There is strong model support for a north-northwest track once Irma makes its major right turn late in the week. The crucial variables will be how long it takes that turn to occur, how sharp the turn is, and whether Irma’s strength has been dented by interactions with Hispaniola and/or Cuba, as noted above.

Bottom line:  It is becoming more likely that Irma will move close enough to the northern Leeward Islands, Puerto Rico, Hispaniola, and/or Cuba for significant impacts. There is an increasing chance that Irma will strike the U.S. late in the weekend or early next week, quite possibly as a major hurricane. It is still too soon to predict the location or timing of any U.S. landfall with confidence.
