Isaac is strengthening

Tropical Storm Isaac is strengthening. An Air Force Reserve hurricane hunter aircraft measured surface winds of 60 mph on the east side of the center, about 170 miles south of Santo Domingo in the Dominican Republic, at 8:40 am EDT this morning. Winds at the aircraft's flight level of 5,000 feet were hurricane force, 76 mph. The surface pressure remained fairly high, at 1000 mb. Tropical cyclones have a warm core, and the Hurricane Hunters typically find that a storm's lowest pressure is also where the warmest temperature are. However, this morning's flight found that Isaac was still disorganized, with the storm showing almost no evidence of a warm core. Isaac's warmest temperatures were displaced 75 miles to the west of where the lowest pressure was. There were no signs of an eyewall beginning to build. Infrared and visible satellite loops show that Isaac is somewhat asymmetric, with a large band of intense thunderstorms to the east, separated from the core region. This is interfering with both the storm's low-level inflow and upper-level outflow, but the band appears to be dying out. An analysis of upper level winds from the University of Wisconsin CIMSS shows an upper-level outflow channel well-established to the north, and an intermittent outflow channel to the south.

Isaac's rains
Radar imagery from Puerto Rico shows that Isaac is dumping some very heavy rains to the south and east of the center. Ponce, Puerto Rico had a wind gust of 37 mph this morning as a heavy band of rain moved through, and radar-estimated rainfall amounts are in excess of 7 inches for the region just north of Ponce. Power outages to 2,000 homes have been reported in Puerto Rico this morning. NOAA buoy 42085 offshore from Ponce reported a wind gust of 54 mph near 9 am EDT this morning. Rainfall estimates from microwave satellite instruments suggest that Isaac's heaviest rains are to the south of the center, and that the Dominican Republic and Eastern Haiti will escape the worst of Isaac's rains. Haiti's southwest peninsula and Eastern Cuba should suffer the heaviest rains.


Figure 2. Radar-estimated precipitation from the Puerto Rico radar shows the region near Ponce has received up to 7" of rain as of 10 am EDT August 24, 2012.

Latest model runs for Isaac
The latest set of 00Z and 06Z (8 pm and 2 am EDT) model runs have come into better agreement, thanks to the dropsonde mission by the NOAA jet yesterday afternoon and evening. Isaac should move over Haiti's southwest peninsula and then eastern Cuba, then track along the spine of Cuba before popping off into the Florida Straits on Sunday. A trough of low pressure will then pull Isaac to the northwest, and then north, towards the Central Gulf Coast. Landfall locations range from Mississippi (06Z HWRF model run) to the Florida Panhandle south of Tallahassee (06Z GFDL model run.) It is possible that the trough of low pressure pulling Isaac to the north may not be strong enough to pull Isaac all the way to the northeast and out to sea, and the ECMWF model indicates that Isaac could stall out after landfall over the Tennessee Valley for several days.

Intensity forecast for Isaac
Isaac has not intensified as much as predicted, and I think that the storm's very large size is partially responsible for that. It's tough to spin up as much atmosphere as Isaac is attempting to do very quickly. Conditions remain favorable for intensification today, with wind shear low, 5 - 10 knots, ocean temperatures warm, 29°C, and dry air mostly mixed out of the storm's core. The large band of intense thunderstorms to the east, separated from the core region, appears to be dying out now, which will help the storm grow more organized. The storm's structure has improved considerably between 9 am - 10 am EDT, with a fairly tight center forming, exposed to view, on the north edge of Isaac's heaviest thunderstorms. A curved band of heavy thunderstorms is now trying to wrap around this center to the northeast, and this band will bring very heavy rains to Haiti and the Dominican Republic this afternoon. I expect that the Hurricane Hunters will observe a partial eyewall in their vortex reports between 2 - 4 pm EDT this afternoon. The storm's large size and disorganized structure suggests that Isaac will be able to intensify only slowly today, and will have top winds of 70 - 75 mph before encountering Southwest Haiti and Eastern Cuba tonight and Saturday. Isaac will likely be a 50 - 60 mph tropical storm on Saturday and Sunday as it moves over Cuba. Once Isaac pops off the coast of Cuba into the Florida Straits, it will be over very warm waters of 31 - 32°C (88 - 90°F), wind shear will be light to moderate. The upper-level wind pattern favorable may be quite favorable for intensification, with low wind shear due to an upper-level anticyclone over the storm--though the models disagree on whether or not this anticyclone will set up directly over Isaac or not. It will probably take at least 24 hours with the storm's center over water for it to become a hurricane. It is possible that Isaac could be approaching Category 3 strength by the time it makes landfall on Tuesday on the Gulf Coast, as suggested by the latest 06Z run of the HWRF model.

Impact on Tampa, Florida
The Republican National Convention begins on Monday in Tampa, Florida. The latest 11 am EDT wind probability forecast from NHC gives Tampa a 17% chance of receiving tropical storm-force winds and a 1% chance of receiving hurricane-force winds on Monday. Tampa is in the NHC cone of uncertainty, though near the edge of it. At a minimum, Tampa will receive very heavy rains and wind gusts in excess of 40 mph. Isaac is going to be hard-pressed to bring hurricane-force winds to the city, though, since any path that takes it close to Tampa would keep the storm too close to land for significant intensification to occur. I put the odds of a mass evacuation being ordered for Tampa during the convention at 1%. I have detailed information on Tampa's storm surge vulnerability in a post from last week.

Invest 97L off the coast of Africa
A tropical wave that moved off the coast of Africa on Thursday has been designated Invest 97L by NHC this morning. The storm has a modest amount of spin and heavy thunderstorms, and is under moderate wind shear of 10 - 20 knots. In their 8 am EDT Tropical Weather Outlook, NHC gave 97L a 30% chance of developing by Sunday morning. The 8 am EDT SHIPS model forecast predicts that 97L will track west-northwest over the next few days, and encounter a region of high wind shear associated with an upper-level low on Monday and Tuesday. This low may be capable of tearing the storm apart, as happened to Tropical Storm Joyce. None of the models currently foresee that 97L will affect the Lesser Antilles Islands, but 97L may pass near Bermuda 7 - 8 days from now.



20th anniversary of Hurricane Andrew
Today, August 24, is the 20th anniversary of Hurricane Andrew, which hit South Florida as a Category 5 hurricane with 175 mph winds--one of only three Category 5 hurricanes ever to hit the U.S. With Isaac churning through the Caribbean this week, I didn't have time to prepare a special post on Andrew, but our Hurricane Andrew archive page has links to satellite and radar images, newspaper headlines, and 49 YouTube videos. Here's an additional link for an Andrew damage video shot by wunderblogger/storm chaser Mike Theiss, when he was 14 years old.

It's easy to see Isaac's center on rapid scan visible loops. It is at least halfway exposed. I wouldn't expect much strengthening until that problem is corrected.


not sure that is really the center, that swirl we are seeing, might be one of those vort maxes
On IR you if you trace the convec over that swirl back in time, you see it came out of the big mass of convec and is rotating in a circular counterclockwise fashion, showing up here in black
That swirl may not be the tru COC and the center might be where the greater mass of convection is wrapping around, and where this swirl is rotating around.:

Weather Channel!!! WHAT IS WRONG WITH YOU, I APPRECIATE YOUR COVERAGE OF THE STORM, but covering it EVERY WAKING MOMENT LIKE KATRINA IS ABOUT TO WIPE OUT NEW ORLEANS AGAIN, COME ON!!!! THIS IS NOT 2004 or 2005 WHERE ALL HELL HAD BROKEN LOOSE!!!!!!!! I HAVE TO ADMIT, I'm GETTING KIND of SICK of THIS!! I estimate that they are spending 90% of their air time talking about Isaac, it's a tropical storm and it isn't even going to affect the US for another two days or so!!!!!!!!!!!!! They might have a reason to cover it as much as they are now when it is over Cuba or the Gulf, but not now, not now.....


This blog is a lot better than TWC for following storms. TWC is OK for some stuff except usually they are showing stories when you need some weather. Of course now they are about to station observers out there in the "cone" and cover the same trees blowing in the wind every few minutes.

Just a statement about model bias. The GFS tends to overdo troughs and the Euro tends to overdo ridges. So it kinda makes sense that the Euro went way west, and it also makes sense that the GFS is trending east. My money is still on Pensacola.

I really, really highly doubt we will see a worst case scenario for Tampa. Here is why. When you consider the type of steering that will be in place with Isaac, I do agree that track may shift closer to Tampa, however a hard right turn in the gulf is very unlikely with this scenario. For this storm to make a direct hit on the Tampa Bay area, it would likely have to first directly hit South Florida, which could still happen, but by then we would just have a butt load of rain and gusty winds. Nothing we aren't used to here in Tampa Bay, torrential rain, tropical storm force winds and tornadoes are common and are part of living here.

I do believe Isaac will take a turn into the eastern gulf, but I don't see how it could impact Tampa as a serious threat. Let's not start letting fear and hype get the best of us.
I'm not saying the worst case scenario is impossible, I mean, if Isaac were to rapidly deepen in a Katrina or Charley way, it could suddenly hook into Tampa. But lets remember the odds of that happening are extremely low. With that said, we must consider all possibility, but not get fearful or induce. Hype, the local MET Denis Phillips would agree with me right now, and that's why I follow his style, its sound science.


I'm not accusing you of hype, I know you are not that way, I'm really posting this for the sake of all bloggers, just be careful that other Floridians here don't think you are telling them that Tampa will be meeting it's doom in a few days.


At this point the storm could still even strike New Orleans. Now if the NHC has say a major hurricane consistently striking Tampa bay of this weekend, which I don't think will happen, then people need to start preparing for the big one, but even with that, people must still remain as calm and collective as they can.
I agree, but I know that the people I see day to day have no idea that a Charley like scenario is even possible here. I've lived in Melbourne, jacksonville, and a couple areas around Tampa. People are seriously lacking an understanding of hurricanes and think Tampa is safe all the time.

Nice trough over the West Central US moving Southeast towards the Gulf. RTS. the trough will erode the BH to the East an open up a weakness over Florida. It all depends on the foward speed of Isaac to determine which sie of Florida it hits.

Much more defined and tighter inner core coming together with Tropical Storm Isaac this early afternoon. Seeing what may be an attempt at building a partial eye wall feature. Could definitely see this become a hurricane before making landfall over Haiti in the next 24 hours.

cchs looks to me TS watches would be issued for mainland south florida from jupiter inlet to florida city and around to bonita beach, and a hurricane watch for the Florida keys what do you think ??

I was looking at the WV Loop and it shows alot of dry air in the eastern GOM...will that move away or will Issac push through it?
Thanks


The dry air is mixed up with the trough right now.

Since that region is several days away from now, it's going to change a lot.

It's the Gulf, so anything can happen, but we should see stuff like pop-up showers and things forming in that area tomorrow or the next day, and then the "calm before the storm" phase on Monday or Tuesday, depending on whether the center line of the cone is correct, or whether it goes left or right.

Personally, I favor the west line of the most recent cone, which pushing the timing back 12 to 24...but I'm not a professional met, so don't take my word for life/death decisions, at least not till 12 to 24 before landfall, because in the event of a serious storm I will be begging whoever is in the path to get the heck out of there, as should everyone.

till, officials had to be prepared for the worst-case scenario, a hurricane in the Gulf, making landfall just north of Tampa, pushing even more water and wind into the Tampa Bay area, said Alex Sosnowski, a meteorologist from AccuWeather. Because a storm can often affect areas 100 miles from its center, people were told to pay attention.

The city's geography has posed logistical challenges from the outset, including how people would get around a downtown that is only about 571 acres — or less than 1 square-mile — and is bordered by interstates and rivers, and punctuated with restaurants, cafes and offices. As many as 400 air-conditioned buses are expected to shuttle delegates and other visitors from their hotels on both sides of the bay to the Tampa Bay Times Forum, the downtown hockey arena hosting the festivities.

Any evacuation orders for the arena, where Romney will give his acceptance speech, would depend on a variety of factors, and would most likely not be made simply because a Category 1 storm, with winds of 74 mph, was approaching, officials said. Some visitors may not even be staying in would-be evacuation zones. Hotels have been booked 20 miles or more from downtown Tampa.

Debra Sue Warshefski, spokeswoman for Tampa Fire Rescue, said the city will provide buses for people to get to shelters and she hoped protesters, especially those who are camping, would take advantage of any offers of help.

“If we call for an evacuation, are we going to require an evacuation and arrest them? No we're going to offer the opportunity for their safety,” she said.

The last hurricane to strike Tampa was Hurricane Jeanne in 2004. The Category 1 storm moved across the state toward Tampa, weakening along the way. It still knocked down trees and power lines, and damaged buildings. Three people were killed, but none in the Tampa Bay area.

Director of meteorology at Weather Underground, Jeff Masters, said based off the latest forecasts and computer models, there was a 3 percent chance of needing to evacuate the arena hosting the convention. There was 9 percent chance of Tampa experiencing tropical storm-force winds of at least 39 mph when the convention begins.

“Those odds are probably going to rise,” he said.

For me it would depend on the degree of difficulty. You probably won't need them, but better safe than sorry, especially if it is an easy process.
For my own part I am still on the plywood system, so I do not bother unless it is at least a guaranteed CAT1, and even then that is more for warm fuzzies than actual protection.

That's a denialist comment, considering Charley was about the same strength when it was in the closest analog position as Isaac.


Ahem, balderdash. This storm is nothing like Charley. He was small and thus quick to intensify, there is nothing to suggest Isaac will head over Western Cuba, not to mention not get shredded apart by Hispaniola. Charley was not this disorganized this late in the game.

And this is a prime example as to why folks should not get worked up over being the bullseye 5 days out, Mobile, Al here. Just less than 12 hours ago was in the crosshairs, now come the 4pm cst today may be on the extreme left edge if in it at all depending on what the next Euro shows. But you still need to keep one eye on it cause it can change back just as fast as it left

Charley is in no way similar to this storm. Charlie was already a Cat 3 when he made landfall on Western Cuba, which has relatively flat land when compared to Haiti and Eastern Cuba. It wasn't that amazing for Charley to strengthen quickly back into a major considering those facts.



Yes and there was also an unusually strong trough for that time of year that had dug into the Eastern Gulf of Mexico, not at all the same setup as expected here. This trough is not expected to have the same strength or orientation at all as that one had.

And Charley was a very small storm which was already a hurricane and very well organized long before it crossed over Cuba, not a disorganized tropical storm struggling to organize over a broad area south of the Greater Antilles, as is the case with Isaac.

When people get into hype mode they will slyly pull up comparisons with past storms that were in the same general area or which were moving in a similar direction or with a similar orientation, in order to try to convince you that the current setup is a mirror image of what happened then. Not so however. Even the subtlest differences can create a huge variance in tropical cyclone characteristics.

That's a denialist comment, considering Charley was about the same strength when it was in the closest analog position as Isaac.

The official intensity forecast is based on statistics and dynamics assuming the track forecast is correct.

If the storm takes the western side of the cone, which is very close to both Charley and Climatology for a storm in this position, then it would probably be much more intense than the center line of the cone.


Remember, this is not an exact science, in spite of the advanced models and technology involved. The intensity forecast is often wrong by a category or two beyond 48 hours, and the NHC and FEMA usually tells people to prepare for a category or two higher than the forecast, just in case...


What? I think you missed the point.

If it takes the extreme western portion of the cone, of course it could become intense.

1000mb:



990mb:



970mb



Notice the weakness is deeper in the 970mb steering layer at the present time, but by the time the storm moves farther west, that weakness won't be there, and the gulf ridge on that steering layer will probably re-merge with the bermuda high, or else move around a bit eastwards anyway, cuz the features over the 4 corners region looks to be moving east to nudge that high some later tonight, tomorrow, etc.


Since the storm is nowhere near 970mb right now, it doesn't matter anyway, but even if it was, it's too far away to matter by much.


Right now I trust the 990mb layer most since the storm will probably be sub-1000mb by the time of the next advisory.

Lots of regulars and folks on here with their opinions. Nothing wrong with that (purpose of the Blog) but in a real situation like this, you need to look at your local weather NWS impact statements and keep an eye on the Official NHC tracks.

The storm should begin a northwesterly movement, clipping Haiti, moving through flat terrain of Cuba, which shouldn't weaken the storm rapidly as originally thought. Potential for a Major Hurricane to hit Florida is there. Charley in 2004 went from a Cat 2 to a 4 in 2 hours. Conditions appear to be RIPE for further development after reaching the Gulf of Mexico. Everyone from the Keys, East/West Coast of Florida, Panhandle of Florida needs to review their Hurricane plans and start preparations for the worst. Anywhere west of Florida, your safe. A storm cannot bust through the corner of a developing ridge, laws of physics and gravity don't work that way. East of 85W Isaac will stay.


Huh?

If it clips Haiti on northwesterly movement it has no choice but to cross the 'mountainous' terrain of Cuba.

Those mountains aren't as tall as the DR, but the tallest is 6500ft and others are in the 4500ft range.
