I often say, hurricane events have 3 phases people go through.
1. Anxiety phase - the prep days leading up to a storm
2. Terrifying phase - going through the storm
3. Indescribable phase - the weeks, months, years of recovery. Many lives have been changed forever.
Hurricane Lee is about 600 miles east of the northeast Caribbean islands. It's way out in the Atlantic, and will be slowing down in the coming days, so this is going to be a long period in what I call the "anxiety phase". So, everyone please pace yourselves mentally &
Tornado just east of downtown Ft Lauderdale this afternoon. Was watching the signature on the radar and it looked like it would be close.
Boy was it. From what I could tell,

issued the warning just in time.
Unfathomable damage in Acapulco as what appears to be contents of entire floors blown out of high rise buildings from cat 5 Otis. Winds always higher in skyscrapers so it’s possible the damage factor was 1000 times higher than what would occur from 75mph cat 1.
Today is my last day at CBS4 Miami, & it's been a great 22 years. I've decided it's time for a change. Like many of you, I have worked non-stop since basically high school. What's next? I'm going to take a little break, maybe do some fishing, but I'm not leaving South Florida.
Complicated forecasts involving big risks such as strong hurricanes require oversized areas of preparation. Here's why this forecast is complex.
Idalia will be guided north for a day or so thanks to high pressure building in from the east. A jet stream dip will try to turn the
Yikes! Woke up to what I thought was lightning, but was power flashes around Ft Lauderdale.
Every meteorologist awake (3:15AM) and much of South Florida right now with the wind howling.
In a bit of meteorological curiosity, big Hurricane Franklin moving northeast in the Atlantic, and small newly formed Tropical Storm Jose are about to meet.
In what is similar to atmospheric Pac-Man, Franklin will gobble up (absorb) Jose in a few days.
The models remain very close with potential threats to the northeast Caribbean, the Bahamas, and the US, but it really is too early to tell if a potential threat will turn into an impactful reality. Below are not models, but past major hurricane tracks (cat 3+) since 1855.
We
Sometimes I question the lack of messaging presented in the 7 day Tropical Weather Outlook. In the first place, it looks like an advisory cone, so many immediately think it is where a storm will track. Second, it is for development potential over a long time frame, seven days.
In the next few days, Hurricane Lee will likely become a category 5 storm & achieve this at a remarkable rate of intensification. And apart from what is really an amazing meteorological event, there will be no direct land impacts other than large swell on Atlantic facing shores
After quickly reaching category 5 intensity 36 hours ago, Hurricane Lee has been struggling against wind shear. As noted by NHC (Berg, Bucci), the Euro suggests the wind shear will persist and "may" keep Lee from intensifying back to cat 4 or 5. This type of El Niño shear was
Interesting trend in models Sun AM, the idea of a strong system turning north in the open Atlantic is losing favor to a weaker system continuing west into the Carib. This more west trend increases odds some folks (land) are going to have to deal with it. The timeline now for

Wow, Zeta bringing with it FIFTY FOOT waves just south of Louisiana now as the fast moving hurricane has likely created a "trapped fetch" where waves moving with storm and growing huge.
Based on the 5PM Sunday NHC forecast advisory, here is the prep timeline for Idalia.
Because the storm is expected to accelerate in the eastern Gulf, the times of arrival have moved up a bit for Tampa Bay.

The main question with the strong wave in the far east Atlantic is, will it have opportunities to go north (recurve) before it gets too far west & close to land?
Right now, the pattern somewhat favors a recurve, but this wave is starting so far south, it may not "sense"
Before a tropical system has developed, there is a lot of model uncertainty. Therefore, we use a range of possibilities to understand a threat, such as model ensembles or multimodel images. We do not use deterministic model runs for undeveloped tropical systems many days out.
So,
And we've reached the part where everything unfolds now and you just watch it, hoping people in its path prepared or evacuated. From a meteorological point of view it's fascinating to watch, from a societal/human point of view its horrifying. Those who have experienced the eye
We are now less than five days from a potential hurricane event and can start discussing possible details/outcomes.
While Hurricane Lee, which is expected to slow down as it approaches the coast, may be seen as good news because the center will be over much cooler water &
A few folks mentioning "Irma" as a similar storm situation. Maybe for intensity, but not for track. Below left are the four primary models (run Sept 5, 2017) that we used in 2017, and all were pointing to a Florida hurricane event. In fact, the signal was so strong that I put up

It’s a dream job utilizing my tropical & marine meteorology experience and allowing me to explore/advance operational maritime science in a way I couldn’t before.
One of the ways we track potential tropical development is with a model's "precipitable water" depiction. Tropical features show up visually & can be easily followed. Thu AM Euro shows a strong wave moving across Trop Atlantic next 10 days with some development indicated. We'll
No US issues for 10 days but I guess we're going to have to start talking about the next Cabo Verde wave set to roll across the deep Tropical Atlantic.
This next system will need to be watched. The models are in agreement forecasting development/intensification regardless of
We are entering the beginning of peak hurricane season lasting through mid-October. And while much of the Atlantic remains warm with above average sea surface temperatures, it also remains mostly quiet. It appears one reason is because the African Easterly Waves (tropical
Based on the 5AM Monday NHC forecast advisory, here is the prep timeline for Idalia. Plan to have outdoor activities/preps wrapped up before tropical storm force winds arrive.
Any slight shifts in the track to the east/right will bring hurricane conditions to the west coast
During hurricane season we never want to wake up to any model surprises, and thankfully this morning, we haven't. The Euro (shown below) & GFS ensembles are in fairly good agreement on a consistent west northwest motion for the next 7 days. We'll keep our eyes on it, but so far,
While you'll often hear me rant about what a bad messaging tool the cone is when used within 3 days of landfall, when a storm is far away, it is effective for helping to establish our timeline. We do our preps based on timelines, not distance from a storm.
As of Thursday,
This Wednesday morning we're looking for any trends in the last several model runs (GFS). Fortunately, there aren't any significant ones, the models are pretty dialed in on the west northwest motion through the weekend.
After that, our first real area of uncertainty occurs at a
We are just about to the point where we can "nowcast" Ian. We know exactly where the center is via radar. Of note, the center is not moving due north, but slightly east of due north. If this trend continues it will imply more impacts on Fla SW coast (Naples, Ft Myers, Sarasota).
Strong tropical wave showing up in most reliable models now coming across the Main Development Region of the Atlantic. While it is not expected to become anything intense, it is a worrisome reminder this season looks primed for a lot of activity.
A good example of high certainty and high uncertainty in ensemble solutions this morning.
We are confident, based on the models, the wave center point crossing the Gulf will go ashore near TX/MX border.
On the other hand, fairly low confidence where exactly Franklin will turn to
The "Cone" (white outline), when used within three days of impacts actually becomes an impediment to messaging. Within 24 hours of landfall, Naples was outside the cone yet under a hurricane warning. I created this graphic incorporating storm size just for this reason.
Regarding potential development heading toward Gulf next week, I think many of the details on what or how strong involves a little upper level low pressure system dropping into the eastern Gulf Monday.
According to the GFS, the low creates wind shear limiting development of the
The apparent center of TD10 has now moved well south of even the southern most forecast points of the previous model runs. South of 20° N was not anticipated. Even yesterday's more south suggested Euro ensemble didn't go this far south.

It's called vortex shedding. It's often there, not as pronounced, but you just can't see it. Think of a rock in a fast moving stream and the swirls that spin off of it.
Something to remember out in the deep tropics, often how strong a storm is, determines where it wants to go, not the other way around. So a stronger system will sense the trough to its north and want to go that way. A weaker system will miss the trough and scoot toward the block.
5AM Tuesday NHC advisory based timing graphic shows how the expected wind field from Idalia fits into the tropical storm/hurricane watches & warnings.
Of note this morning, the faster forward speed means two things. 1, preps in the direct path need to be wrapped up today. 2, as
Based on history, a storm in the position of Lee is about 8 or 9 days from the US. Lee might even end up being a little slower, if it impacts the US at all.
Typically we only watch a storm this far out timewise, and if we don't have our June 1 hurricane kit & plan, it's a
@MattDevittWX
On the contrary, it's actually not that bad. Winds SE right now at 25 knots. Once we're clear of the oil rigs, we'll blast on southeast and by morning, sunshine and smooth sailing. :-)
With the recent Florida tornadoes, before folks start saying "we never had tornadoes here before" or similar phrases, let's look at a little tornado history, thanks to NOAA's Storm Prediction Center.
Over the past 30 years, Florida ranks fourth in the nation for tornadoes.
Based on the 5PM Wed NHC advisory, expected time of arrival (and cessation) of tropical storm conditions for Hurricane Lee.
Folks in New England and southeast Canada should have outdoor activities wrapped up by sunset on Friday. In other words, by Friday sunset, plan to be
There is very good consensus on the models right now, so if NHC starts advisories, we will likely see a cone pretty much centered on the tightly clustered model tracks. Differences are "along track" meaning timing of arrival from Tuesday night to Wednesday night range.

Consider this like a Storm Prediction Center beyond 3 day outlook graphic. The threat means "chances preparations needed for a hurricane". It's like a heads up graphic. Southern Leeward, Windward, Barbados, T&T, northeast coast of Venezuela, should all be watching closely. Oct 2.
The models seem to be doing a pretty good job with a fairly complex pattern. Of course we won't know for sure until after it all happens, but the run to run & model to model consistency is fairly high right now.
Several steering features will be in play over the next week or so.
While it's easy to conflate storms that move along similar paths, Beryl WILL NOT BE A Harvey event for Houston.
Days before Harvey made landfall southwest of Houston near Corpus Christi, it was known the atmospheric steering currents would collapse, stalling the storm near the
While Franklin makes an east jog before resuming north motion in the Atlantic, the Euro continues to show a signal for something developing out of the NW Carib & moving into the eastern Gulf. That signal is not there in the GFS. Because nothing exists to track right now, we
Enhanced satellite shows classic doughnut eye wall with intense hurricanes moving inland. A rarely issued Extreme Wind Warning has been issued for areas just south of NOLA for winds over 115mph. Folks who live in hurricane zones also know this as "time to hunker down".
After remnants of Lee moves on out, Margot spins, and TD15 becomes Nigel but stays out to sea, maybe we'll have a break in the Atlantic and be at 2023 hurricane season half-time.
As many expected, lots of Atlantic activity, but thankfully few large impact threats to the
Just a reminder that until a persistent tropical feature we can track develops, the models don't provide much planning guidance. So all the hype of where this *might* go from reposting models, is nothing more than rolling dice with your number possibly coming up.
Hurricane Lee is now moving northward at a steady pace. At this point with northward motion established, we gain some confidence in the model solutions.
We are operating on a preps timeline (see next tweet). We don't want to be doing anything outdoors once the bad weather

This seems to be a big player once [Ian] gets into Gulf. Euro (12z) holds a piece of trough back turning [Ian] to the northeast across central/south Florida. GFS (18z) moves out trough leaving [Ian] in light steering flow (drifting storm). Days 3-5 differences remain large.
Not surprisingly, a very bad night in Bimini as the center of the circulation with winds likely near or above hurricane force passed directly over the Bahamian island (north and south Bimini).
NOAA Hurricane Hunter plane just reported 992mb, and not in center so probably lower. If this is a good QC pressure, then the RI has begun. Much of the day Ian was holding steady in the low 1000s, this is a big drop.
This is kind of a messy pattern in the models. They are having very poor model to model consistency, and it makes for challenges in determining what & where something might develop.
The Euro remains bullish (on everything) developing a depression/storm, bringing it to western
People already asking how models did on Ian. First glance GFS, HWRF, HMON way too far west first three days. Euro close on track but a little too slow. NHC also too far left of track. By 5 days, GFS way left, Euro a little right. Goal is to hit the bullseye.
We're knocking on the door to the start of the 2024 Atlantic hurricane season & already we have a healthy looking very low latitude tropical wave out there. Shear should keep this from developing but active waves in June (May) are usually not a good sign for the season ahead.
Hurricane WATCH now in effect for Broward & Palm Beach counties. Tropical storm WATCH now in effect for Miami-Dade. Tropical storm or hurricane conditions are POSSIBLE in these areas within the next 48 hours.

Please don't use NAM 3-KM for tropical cyclones. It was never built to be a tropical model and creates extreme outliers. NHC doesn't use it, you shouldn't either. In other words, no, a cat 4 is not expected to hit Long Island.
Lots of questions so I'll go back to what I said this yesterday, and it still applies today.

I guess we shouldn't be surprised with an "I" storm. Ian appears to be going through an eyewall replacement cycle, and fairly quickly at that. Good news is, intensity will come down for a bit, bad news is the hurricane wind field will grow bigger.
The SW Atlantic developing low pressure area has been designated 98L allowing us to have a model & data window on the feature. Sun AM runs show lots of turns, one from N-NW-W-SW, then one back to the NW-N-NE. Turns make a forecast have higher uncertainty.

Atlantic disturbance looking very healthy & advisories will likely be started today, TS Bret or TD 3.
It appears the center may have formed/relocated a bit father north based on these images. A farther north initial position could have downstream implications to forecast track.

5am NHC advisory for Hurricane Ian. Every time you hear "hazards extend outside the cone" this is what they mean, and why I created this graphic. The cone is tracking a point on the map, but Ian is much bigger than a single point.
Besides the global models (GFS, ECM, ICON) we have some very good regional hurricane models (HAFS). We'll be following their output for track & intensity closely in the coming days. Their skill should even get better once NOAA hurricane hunter planes use Tail Doppler Radar (TDR)
Looking good in the tropics, now let's hope we can keep it that way for many months. It wasn't a very active season for most, but for Florida it was a rough one.
