Bonnie weakens to a tropical depression

Tropical Depression Bonnie is nearing the end of its traverse of South Florida, and passage over land has significantly disrupted the small storm. Satellite images show almost no heavy thunderstorms near Bonnie's center of circulation, and the center is now exposed to view. Radar-estimated rainfall from the Key West radar shows that Bonnie dumped very little rain on South Florida--maximum rainfall amounts from the storm were about four inches over a small region southwest of Miami. Water vapor satellite loops show that Bonnie is embedded in a large area of dry air, thanks to an upper level low to the west over the Gulf of Mexico. This low has brought an increasing amount of wind shear to Bonnie today, and shear has increased from 20 knots this morning to 25 knots this afternoon. Surface observations in South Florida currently don't show any tropical storm force winds. Bonnie's top winds today were at Fowey Rocks, which had sustained winds of 46 mph, gusting to 53 mph, at 10:45 am EDT.

Track Forecast for Bonnie
The latest set of model runs from 8am EDT (12Z) are very similar to the three previous sets of runs, and this degree of consistency gives me confidence that Bonnie will stay within the cone of uncertainty depicted on the track forecast images. The projected track will take Bonnie over the oil spill region, and the storm's strong east to southeasterly winds will begin to affect the oil slick on Saturday morning. Assuming Bonnie doesn't dissipate over the next day, the storm's winds, coupled with a likely storm surge of 2 - 4 feet, will drive oil into a substantial area of the Louisiana marshlands. However, the current NHC forecast has Bonnie making landfall in Louisiana near 9pm CDT Saturday night. According to the latest tide information, this will be near the time of low tide. This will result in much less oil entering the Louisiana marshlands than occurred during Hurricane Alex in June. That storm brought a storm surge of 2 - 4 feet and sustained winds of 20 - 30 mph that lasted for several days, including several high tide cycles. The latest oil trajectory forecasts from NOAA (Figure 2) predicts potential oil impacts along a 150-mile stretch of Louisiana coast on Sunday.

Intensity Forecast for Bonnie
Bonnie has been disrupted by its passage over land, and it will take at least six hours for the storm to reorganize once it moves over the warm waters of the Gulf of Mexico tonight. This process will be hindered by the large upper-level low to its west. If the low remains in its present location, relative to Bonnie, it will bring high wind shear of about 20 - 30 knots to the storm. This will allow for only slow intensification, or may even destroy Bonnie. Bonnie is unlikely to intensify to more than a 50 mph tropical storm, and I give a 30% chance it will dissipate over the Gulf of Mexico before making landfall. The GFDL model predicts Bonnie could hit the Gulf Coast as a 50 mph tropical storm, but the other major models such as the HWRF, GFS, ECMWF, and NOGAPS show a much weaker storm. I don't give Bonnie any chance of becoming a hurricane. NHC is putting the odds of Bonnie being a hurricane at 2 pm Saturday at 4% (5pm advisory.)

If you are wondering about the specific probabilities of receiving tropical storm force winds at your location, I recommend the wind probability product from NHC. The latest probabilities of various locations getting tropical storm force winds, 39 mph or higher, from the 5pm EDT advisory:

Buras, LA 30%
New Orleans 28%
Mobile, AL 37%
Pensacola, FL 30%

The NHC probably wants to continue advisories at least until the 5am advisory to make sure no organization occurs.

In all seriousness, there is no reason why this should be a tropical depression. Evident open circulation, if Bonnie is still a tropical depression, 92L should have been a tropical storm. Makes ya' think that the NHC classifies a system by their threat instead of going by the book.


At this point they're likely maintaining continuity until they are 100% certain Bonnie is no longer a tropical cyclone.

Thanks to you both. I will read the linked info, and try and figure out why a low pressure wave is different at sea than on land.

Lots of low pressure areas cross the continent every year, and I am unsure of what the ones that develop a closed center of rotation are called.

Back after some book learning.

Honestly I am both surprised they are still calling it a depression and still more surprised that they are still forecasting intensification before landfall. Although Beven mentions the likelyhood of dissipation, I see no reason to go the other way. What is going to improve over the next 24 hours that will allow this to come back? Nothing. Oh well.

TROPICAL DEPRESSION BONNIE DISCUSSION NUMBER 7
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL AL032010
1100 PM EDT FRI JUL 23 2010

BONNIE IS CURRENTLY COMPRISED OF A CONVECTIONLESS SWIRL OF LOW
CLOUDS EMBEDDED IN A LARGER-SCALE LOW-LEVEL TROUGH. AN AIR FORCE
RESERVE HURRICANE HUNTER AIRCRAFT INVESTIGATING THE SYSTEM HAS
FOUND WINDS NEAR TROPICAL-STORM FORCE NORTH OF THE CENTER...BUT IS
HAVING A HARD TIME FINDING WESTERLY WINDS ON THE SOUTH SIDE. THE
AIRCRAFT DATA DOES SHOW A CLOSED LOW PRESSURE AREA WITH A CENTRAL
PRESSURE OF 1010 MB. BASED ON THIS CONFLICTING INFORMATION...
BONNIE REMAINS A 30 KT DEPRESSION AT THIS TIME.

THE CYCLONE HAS TURNED A LITTLE TO THE LEFT DURING THE PAST SEVERAL
HOURS...WITH THE INITIAL MOTION NOW 295/15. BONNIE REMAINS ON THE
SOUTH SIDE OF A DEEP-LAYER RIDGE OVER THE SOUTHEASTERN UNITED
STATES AND EAST OF A LARGE MID/UPPER-LEVEL LOW CENTERED OVER THE
WEST CENTRAL GULF OF MEXICO. THIS COMBINATION IS FORECAST TO STEER
THE STORM TO A LANDFALL ALONG THE NORTHERN GULF COAST. ALL THE
TRACK GUIDANCE AGREES WITH THIS SCENARIO...WITH THE MODELS
CLUSTERED OVER THE SOUTHEAST LOUISIANA AND SOUTHERN MISSISSIPPI
COASTS. AFTER LANDFALL...BONNIE OR ITS REMNANT LOW SHOULD TURN
NORTHWARD AT A SLOWER FORWARD SPEED AROUND THE WESTERN END OF THE
RIDGE. THE NEW FORECAST TRACK IS SHIFTED TO THE LEFT BASED UPON
THE CURRENT POSITION AND MOTION...AND LIES JUST TO THE RIGHT OF THE
CENTER OF THE GUIDANCE ENVELOPE.

BONNIE REMAINS IN A LESS THAN IDEAL ENVIRONMENT OF STRONG
SOUTHEASTERLY VERTICAL WIND SHEAR...CONFLUENT UPPER-LEVEL FLOW...
AND UPPER-LEVEL DRY AIR ENCROACHING ON THE CYCLONE. MOST OF THE
INTENSITY GUIDANCE RESPONDS TO THIS BY SHOWING WEAKENING OR
DISSIPATION BEFORE LANDFALL...WITH ONLY THE SHIPS AND LGEM SHOWING
ANY INTENSIFICATION. THE INTENSITY FORECAST IS BASED ON THE
PREMISE THAT ENOUGH CONVECTION WILL RE-DEVELOP TO CAUSE SLIGHT
STRENGTHENING BEFORE BONNIE REACHES THE NORTHERN GULF COAST. AN
INCREASINGLY LIKELY ALTERNATIVE SCENARIO IS THAT THE CYCLONE WILL
DECAY TO A REMNANT LOW OR OPEN TROUGH SOMETIME ON SATURDAY DUE TO A
LACK OF CONVECTION.

FORECAST POSITIONS AND MAX WINDS

INITIAL 24/0300Z 26.4N 83.4W 30 KT
12HR VT 24/1200Z 27.7N 85.7W 30 KT
24HR VT 25/0000Z 29.2N 88.5W 35 KT

Wow, Could a Cat5 atomize the oil and disperse it into the atmosphere?

The oil's one thing, the 2 million gallons of Corexit is quite another. There's already circumstantial proof that is getting carried inland and dropping as acid rain all over the south/southeast, midwest and even through the northeast. 2-butoxyethanol is the primary poison involved and I shudder to think what will happen as more storms continue to push inland.

Tropical cyclone



Hurricane Isabel (2003) as seen from orbit during Expedition 7 of the International Space Station.

The eye, eyewall and surrounding rainbands that are characteristics of tropical cyclones are clearly visible in this view from space.

A tropical cyclone is a storm system characterized by a large low-pressure center and numerous thunderstorms that produce strong winds and heavy rain.

Tropical cyclones feed on heat released when moist air rises, resulting in condensation of water vapor contained in the moist air. They are fueled by a different heat mechanism than other cyclonic windstorms such as nor'easters, European windstorms, and polar lows, leading to their classification as "warm core" storm systems.

The term "tropical" refers to both the geographic origin (as in originating between the Tropic of Cancer and the Tropic of Capricorn) of these systems, which form almost exclusively in tropical regions of the globe, and their formation in maritime tropical air masses. The term "cyclone" refers to such storms' cyclonic nature, with counterclockwise rotation in the Northern Hemisphere and clockwise rotation in the Southern Hemisphere.


Depending on its location and strength, a tropical cyclone is referred to by names such as hurricane, typhoon, tropical storm, cyclonic storm, tropical depression, and simply cyclone.



While tropical cyclones can produce extremely powerful winds and torrential rain, they are also able to produce high waves and damaging storm surge as well as spawning tornadoes. They develop over large bodies of warm water, and lose their strength if they move over land.

This is why coastal regions can receive significant damage from a tropical cyclone, while inland regions are relatively safe from receiving strong winds. Heavy rains, however, can produce significant flooding inland, and storm surges can produce extensive coastal flooding up to 40 kilometres (25 mi) from the coastline.



Although their effects on human populations can be devastating, tropical cyclones can also relieve drought conditions. They also carry heat and energy away from the tropics and transport it toward temperate latitudes, which makes them an important part of the global atmospheric circulation mechanism.

As a result, tropical cyclones help to maintain equilibrium in the Earth's troposphere, and to maintain a relatively stable and warm temperature worldwide.

Many tropical cyclones develop when the atmospheric conditions around a weak disturbance in the atmosphere are favorable.

The background environment is modulated by climatological cycles and patterns such as the Madden-Julian oscillation, El Niño-Southern Oscillation, and the Atlantic multidecadal oscillation.

Others form when other types of cyclones acquire tropical characteristics. Tropical systems are then moved by steering winds in the troposphere; if the conditions remain favorable, the tropical disturbance intensifies, and can even develop an eye.

On the other end of the spectrum, if the conditions around the system deteriorate or the tropical cyclone makes landfall, the system weakens and eventually dissipates. It is not possible to artificially induce the dissipation of these systems with current technology.

I have a question if you don't mind. I am learning by reading, but have non seen this asked or addressed in any thread here.

What is the difference in a wave and a low pressure system? Is a wave identified as being over water and a lps identified as being over land?

Thanks

Usually talking about a tropical wave being open (no circulation), and a tropical low being a closed circulation. Both being over water.

I don't think they are going to know just how bad it is for quite sometime.

They ummm dispersed it (out of sight, out of mind)

This isn't a threat and they all know that.
