Potentially dangerous 92L steadily developing; Igor nears hurricane strength

By: Dr. Jeff Masters, 3:04 PM GMT on September 11, 2010

A tropical disturbance (92L) over the Eastern Caribbean, a few hundred miles south of Puerto Rico, is steadily organizing and appears likely to develop into a tropical depression by tonight or Sunday morning. Satellite loops show an impressive and expanding region of heavy thunderstorms, with good spiral banding and respectable upper-level outflow on all sides. Long range radar out of Puerto Rico shows that heavy rains are now affecting that island, but there is no rotation to the radar echoes evident. However, the rain bands are becoming more intense and more organized. San Juan, Puerto Rico reported a heavy rain squall at 8:44 am this morning, and radar estimates suggest two inches of rain fell in this squall just southeast of San Juan. Wind shear over 92L is low, 5 - 10 knots. The waters beneath are at near-record warmth, 30°C, and these warm waters extend to great depth. Water vapor satellite loops show a large area of dry air lies to the north and west of 92L, and this dry air could interfere with development at times over the next few days.


Figure 1. Morning satellite image of 92L.

Track forecast for 92L
The disturbance is moving west-northwest at 11 mph, and steering currents favor a continuation of this motion for the next three days. Model support for development is scattered. The GFS and NOGAPS models do not develop 92L. The GFDL and ECMWF models predict development, with a track taking 92L into Mexico's Yucatan Peninsula on Wednesday. The HWRF model has a more northwesterly track, taking 92L over the Dominican Republic, Haiti, and Cuba, but this model has been trending too far north in its tracks. I expect 92L will follow a path south of the islands, bringing it near or just south of Jamaica on Monday, then into the Yucatan Peninsula on Wednesday. On this track, the southern Dominican Republic can expect heavy rains of 3 - 6 inches tonight through Monday morning; southern Haiti can expect similar rains Sunday through Monday, and Jamaica and the Cayman Islands can expect heavier rains of 4 - 8 inches Monday and Tuesday. Eastern Cuba will probably escape 92L's heaviest rains in this scenario (Figure 2.)

Intensity forecast for 92L
I can't find any reason to doubt this will be a tropical storm by Sunday or Monday, and potentially a Category 1 or 2 hurricane by Wednesday, if 92L avoids passage over Hispaniola and Cuba. The SHIPS model predicts wind shear will remain low, 5 - 10 knots, through the period, and makes 92L a Category 1 hurricane by Monday night. Water temperatures are certainly warm enough to support development. The main detriment to intensification is likely to be dry air, and 92L could wrap in some of the dry air to its northwest at times, slowing down development. The first Air Force Hurricane Hunter mission into 92L is scheduled for Sunday afternoon, but there will be a research mission by the National Center for Atmospheric Research G-V jet today that will give us valuable information on 92L's large scale environment and potential for development.


Figure 2. Forecast rain amounts from 92L from the 2am EDT Saturday run of the GFDL model. This model predicts most of 92L's heaviest rains will miss Haiti, but will affect Jamaica, the Cayman Islands, and the Yucatan Peninsula. Image credit: Morris Bender, NOAA/GFDL.

Igor
Tropical Storm Igor is very close to hurricane strength, and appears destined to become a large and powerful major hurricane over the Central Atlantic in the days to come. Wind shear is moderate, 15 - 20 knots, waters are warm, 28°C, and Igor has moistened its environment enough to keep the dry air of the Saharan Air Layer (SAL) at bay. Igor will track west under the influence of a strong ridge of high pressure for the next three days, then turn more to the west-northwest in response to the steering influence of a broad trough of low pressure moving across the Western Atlantic on Tuesday and Wednesday. This should allow Igor to pass several hundred miles to the northeast of the Lesser Antilles. In the longer range, Igor may be a threat to Bermuda, and has a slight chance of making landfall on the U.S. East Coast or Canada. Climatology shows that about 10% of all tropical cyclones that have existed at Igor's current position have gone on to hit the U.S. East Coast; these odds are about 10% for Bermuda and 5% for Canada. The forecast steering pattern for the coming two weeks from the GFS model shows a continuation of the pattern we've seen all hurricane season, with regular strong troughs of low pressure moving off the U.S. East Coast. This pattern favors Igor eventually recurving out to sea without affecting any land areas. The odds of Igor hitting land in the U.S. or Canada are probably close to their climatological 10% and 5% probabilities, respectively.

Elsewhere in the tropics
A new tropical wave (Invest 93L) emerged from the coast of Africa yesterday, and is already showing signs of organization. Most of the models predict 93L will develop into a tropical depression 2 - 4 days from now, and NHC is giving 93L a 30% chance of developing by Monday.

This may be my only post today; I'll have a new post Sunday morning.

...yepper,looking out my window at the gom,moved here in oct 08.....haven't seen any strong TC's come close to our area since i moved out here,i think a cat1 or 2 would be very interesting to ride out,would get some amazing pics for sure,a major comes and theirs know way in heck i wouldn't evacuate inland to my dads on palmer ranch!!!

I evacuated from Rita (a bust for us) and from Ike. When I came back from Ike and saw the damage a Cat 2 could do (I was on the "good" side and not in a storm surge location), I decided then that I will not even ride out a Cat 1.

92L has a COC and I still say TD 13 by 5pm
Morning all. Quite a turnaround from yesterday on some stuff. 92L still at 50%, while we're looking at 100% and possible TS warnings for 93L....

The other thing that caught my eye this a.m. is no Twaves in the basin. This current system coming off Africa [the one likely to become Julia sometime today] is the second or third in a row to impact the CVIs as a TD or TS.... just an amazing difference from previous seasons when 3-5 Twaves could easily be located between Africa and Central America.

I'm also starting to lose my optimism about the early recurve on these long-track systems. Only one of them needs to miss a trough to bring major category winds/rain/surge to landfall anywhere from the NE Antilles to the NE US.... I'm starting to feel the tension of inevitability....

Interesting ECMWF has been to strong with the ridges this tropical season and the GFS to weak lol

SOOO true! I couldn't evacuate for Rita and live about 100 miles up from the coast. I still had a tree on my house and three trees I had to cut down as they were growing horizontal to the ground after Rita. They never went back upright. Luckily, I don't have anymore trees close to the house if another one comes this way.

Another Oil Disaster, This Time in the Caribbean Link
It's a question, of course, that has been repeated recently throughout Gulf Coast communities in the United States; in Michigan in July when a burst pipeline dumped 800,000 gallons of oil into the Kalamazoo River; and in scores of other places around the world where petroleum regularly leaks, gushes, explodes or burns -- without attracting all the media attention devoted to the BP disaster in our backyard.

Computer Models Used to Forecast Hurricanes -------->


The behavior of the atmosphere is governed by physical laws which can be expressed as mathematical equations. These equations represent how atmospheric quantities such as temperature, wind speed and direction, humidity, etc., will change from their initial current values (at the present time). If we can solve these equations, we will have a forecast. We can do this by sub-dividing the atmosphere into a 3-D grid of points and solving these equations at each point. These models have three main sources of error:

Nice, surfmom. Thanks. Nice morning tune to go with my java, too.

Woke up last night and couldn't resist checking out the loops after getting some water.

Igor was really ramping up and I see that is continuing.

Waiting for some recon (two days). Like with Earl, all W of forecast. But, once they got some recon, they were pretty darn accurate.

The SHIPS model has been fairly robust w/ Igor's intensity thus far. We'll see if this plays out...

Quoting extreme236:


Any readings I saw that were that high were above the usual flight level, or were from dropsondes. The data may or may not have been accurate, but the NHC doesn't hold back on wind readings that high if their legitimate.

TD12 is here!


Does it look like a developing system??
Gotta say some things about 92L.


It looks weak still, but the potential is definitely there for TD soon and intensification to hurricane sometime in the near future.

There is an anticyclone over it right now, and it's starting to get out of the dead zone.

Now my synoposis of what TWC is probably saying about Igor right now:

"Igor is a minimum category 1 hurricane, with no signs of further development at this time. Stay tuned with the Weather Channel for all your up-to-date information about the tropics. Let's get back to Al Roker in the studio for Wake Up With Al."

If I am understanding this correctly pressure supports a TD but winds only 30mph. Pressure drop should be a sign of organization happening. Correct ?

Models are beginning to agree on a strong positive NAO signal towards the end of the month. THis is the pattern change we have been waiting for, in regards to potential Eastern US landfalls. However it is still long range, so it could still change some over the next 5 days.
92L looks more impressive again this morning, but we saw the same thing yesterday morning. We'll have to see if it persists this time.
Igor should be a Major hurricane at 11am advisory this morning, very impressive RI this morning.
I think the NHC predicted a Major by Tuesday sometime. This system will def. become a major late this evening if it's not already. Look at the eye formation. I have never seen an eye look so good on a 80mph storm. We should see the winds increased on the 11am advisory
