Why is it always Wednesday?<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

There\u2019s no answer beyond coincidence for why Florida\u2019s four most recent hurricanes \u2014 Michael, Sally, Ian, and Nicole \u2014 have all struck on the same cursed day of the week.<\/p>\n\n\n\n

Idalia remains on a collision course with the Florida Gulf Coast.<\/p>\n\n\n\n

Track expectations have changed only modestly since Sunday, and landfall is most likely in Apalachee Bay or the northern Nature Coast by mid-day Wednesday. Idalia will likely bring a catastrophic surge to a broad swath of the west-central Florida and Big Bend coastline, and a core of destructive winds to an unlucky but still unknown swath of North Florida.<\/p>\n\n\n\n

Tracking Idalia<\/strong><\/p>\n\n\n\n

As of mid-day Monday, the center of Idalia has begun its trek north toward the Gulf of Mexico, and is located about 500 miles south of Tampa, moving due north at about 8 mph. Idalia\u2019s movement as tracked by Hurricane Hunter aircraft and Cuban and Mexican radar has closely followed the NHC forecast track. Most model guidance over the past 12-24 hours, and the official track forecast is little changed since Sunday afternoon.<\/p>\n\n\n\n

Hurricane and Storm Surge Warnings are now in effect.<\/p>\n\n\n\n

Maximum sustained winds are 70 mph per the NHC 2 p.m. Monday advisory, with the storm remaining somewhat lopsided for the moment due to drier air and limited outflow in the northern half of the storm. Reconnaissance observations and guidance suggest these factors will keep Idalia\u2019s rate of strengthening in check through early Tuesday.<\/p>\n\n\n\n

Rapid intensification coming and a Cat-4 hurricane is possible<\/strong><\/p>\n\n\n\n

Unfortunately, conditions remain prime for rapid intensification starting Tuesday morning. Dry air is expected to have mixed out of Idalia\u2019s core by that time, and the incredible heat energy of the eastern Gulf at the surface teams twin outflow jets aloft are likely to trigger a scary increase in intensity into early Wednesday.<\/p>\n\n\n\n

It\u2019s impossible to peg how high this potential rapid intensification cycle will go. As of Monday, the NHC is now predicting a Category 3 hurricane in the eastern Gulf, and a peak at Category 4 is certainly a possibility. <\/p>\n\n\n\n

The track forecast continues to be tightly focused on a path toward the eastern Panhandle and northern Nature Coast. Accounting for a mid-day Monday nudge westward with track guidance, the most probable landfall range is between Alligator Point and Crystal River, likely Wednesday morning or early afternoon. With Idalia now embedded in a narrow channel of steering winds between high pressure to the west and a dip in the jet stream to its north, we are not likely to see huge leaps in the projected path.<\/p>\n\n\n\n

The most probable landfall range is between Alligator Point and Crystal River, likely Wednesday morning. As always, minor adjustments in the forecast track are likely over the next 36 hours, but don\u2019t bank on an eleventh-hour reprieve if you are in the projected path of Idalia.<\/p>\n\n\n\n

The anticipated landfall on Wednesday is a dangerous and extremely rare scenario for north-central and west-central Florida. While the Big Bend and Nature Coast are no stranger to hurricanes, should Idalia make landfall there as a major hurricane, it would be just the second Category 3 or higher to strike to do so in the last 170 years.<\/p>\n\n\n\n

As the only other major hurricane in that section of the coast hit in 1896, there are a lot of communities that are going to be tested by all four hurricane hazards \u2014 surge, wind, rain, and tornadoes \u2014 with no modern reference point for such an event.<\/p>\n\n\n\n

Let\u2019s go one-by-one through each of those hazards to get a full picture of the threat Idalia poses to Florida.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

A storm surge event unlike any other with catastrophic coastal flooding<\/strong><\/p>\n\n\n\n

Water is the true killer in a hurricane, and there is no hazard more deadly or destructive in a hurricane than storm surge. No matter the precise track, Idalia will be a surge event unlike any hurricane in the modern era for west-central Florida. The powerful windfield of Idalia\u2019s eastern half will push a wall of water north onto the shallow Gulf continental shelf that last-minute changes in maximum winds or track can\u2019t alter. Additionally, an untimely supermoon on Wednesday will further enhance tides and coastal flooding potential.<\/p>\n\n\n\n

As such, Storm Surge Warnings are in place for much of Florida\u2019s Gulf Coast, now extending from central Apalachee Bay to just north of Charlotte Harbor, including Tampa Bay. NHC modeling is currently calling for peak surge of 7-11\u2019 from eastern Apalachee Bay and along the Nature Coast.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

For Apalachee Bay, 7-11\u2019 of surge is a potential value; if Idalia\u2019s center tracks south and east of the Bay, actual surge will be lower than in the very possible outcome of Idalia tracking through the Bay. We won\u2019t know what will happen until closer to landfall, so hope for the best but absolutely prepare for the worst here, especially with mid-day Monday model guidance ticking a bit farther west.<\/p>\n\n\n\n

For the Nature Coast, this surge is life-threatening, without living precedent, and very likely to happen. Whether Idalia makes landfall in the Nature Coast or passes just to your north and west, strong, onshore winds out of the southeast driving catastrophic coastal flooding are virtually certain to a greater or lesser extent.<\/p>\n\n\n\n

If you are told to evacuate, leave. You can hide from the wind, but you need to run from water.<\/p>\n\n\n\n

This applies to Tampa Bay as well, where the current NHC projection is 4-7\u2019 of surge. While Idalia will not make landfall in Tampa, a track west of the metro area means south and southeast winds will push water into the bay, rather than out of it as in Irma and Ian.<\/p>\n\n\n\n

Know your evacuation zone, have a way of receiving emergency information, and react if you get an evacuation order. Even moving just a few miles inland can keep you out of harm\u2019s way.<\/p>\n\n\n\n

Southwest Florida, though well away from the storm itself, is also likely to see 2-4\u2019 of surge above normal high tides. This area is under a Storm Surge Watch as of mid-day Monday.<\/p>\n\n\n\n

Winds: A truly ferocious punch is coming, but the target isn’t clear<\/strong><\/p>\n\n\n\n

Wind is the hardest hurricane threat to pin down. While damaging, tropical-storm-force gusts capable of knocking out power and damaging trees will occur over a wide region extending from the Central Panhandle to Central Florida to coastal Southwest Florida, Idalia\u2019s truly destructive winds, are likely to occur over a much more limited area area near the center of circulation.<\/p>\n\n\n\n

For this reason, it\u2019s too soon to put a fine point on local wind expectations, not for the least of reasons that maximum winds can ramp up or down quickly.<\/p>\n\n\n\n

In the eastern Panhandle, including Tallahassee, we simply don\u2019t know at this point whether Idalia will pass far enough south and east of us such that hurricane-force winds will miss us, or whether we will get a portion of Idalia\u2019s core.<\/p>\n\n\n\n

Both are possible.<\/p>\n\n\n\n

What can be said at this point is the highest chances of wind gusts exceeding 100 mph are focused on the west-central Florida and eastern Apalachee Bay coastlines. The highest chances of hurricane-force wind gusts inland are roughly between Gainesville, Tallahassee, and coastal Georgia. This could change.<\/p>\n\n\n\n

Rainfall: A very real but secondary threat<\/strong><\/p>\n\n\n\n

When people think of hurricane threats, excessive rainfall and flooding isn\u2019t necessarily the first thing that comes to mind. But it should be \u2014 nearly one-third of tropical cyclone-related casualties are caused by freshwater flooding.<\/p>\n\n\n\n

With Idalia likely accelerating by landfall to a forward speed of a brisk 15-20 mph, heavy rainfall will be a secondary impact of the storm. Periodic rain bands will overspread the southern half of Florida through mid-day Tuesday, and the remainder of the state by Tuesday night.<\/p>\n\n\n\n

Look for rains to be heaviest and most persistent through mid-day Wednesday in the eastern Panhandle, northeast Florida, and west-central Florida, where storm totals of 4-8\u201d are likely and localized flash flooding is possible. Otherwise, accumulations across the state will be 1-4\u201d, with a sharp cutoff in Idalia\u2019s rains and much lower totals in the western Panhandle.<\/p>\n\n\n\n

Tornadoes: A hurricane’s deadly spawn<\/strong><\/p>\n\n\n\n

Tornadic activity is common in landfalling hurricanes, mostly in bands north and east of the circulation center. Occasional tornadic cells within outer bands are most likely on Tuesday in west-central Florida, with some chance of short-lived tornadoes across the rest of the peninsula as well. Tornado risks will spread north and focus on northeast Florida on Wednesday.<\/p>\n\n\n\n

It\u2019s hard to find much of a cause for optimism as yet another Wednesday\u2019s child, full of woe, bears down on Florida.<\/p>\n\n\n\n

Idalia is a four-quadrant threat that will combine widespread life-threatening and damaging surge with more locally destructive wind impacts. These projected impacts may shift prior to landfall, and everyone in Southwest Florida, Central Florida, North Florida, and the eastern Panhandle should be closely monitoring the latest information from the National Hurricane Center, your National Weather Service office, and local emergency management. You have until Tuesday evening to prepare, so use your time wisely. I will be back tomorrow with a region-by-region threat breakdown ahead of the worst of the storm. <\/p>\n","protected":false},"excerpt":{"rendered":"
