Latest image of Tropical Storm Arthur shows it getting organized

As we mentioned yesterday, Tropical Storm Arthur is likely to become hurricane Arthur and threaten the Outer Banks of North Carolina on the Fourth of July, one of the busiest holidays there. A potential nightmare scenario.

NASA’s Earth Data page is  great resource to get hi resolution satellite imagery from. This one shows how Arthur, off the coast of South Florida is becoming more organized.

    So make this a lesson.

    What is telling us in the great white fuzz that it is “getting organized”, and what does that phrase mean? Please consider me a weather ignoramus, with a knowledge level enough to read a weather rock.

  2. Kenw says:

    “more organized =
    -more circular in appearance
    -distinctive center
    -distinctive bands with more uniform radiation patterns

    among others.

    If this storm becomes a hurricane, that will be clear unambiguous proof of global warming

    Have we ever had a hurricane threaten the U.S. in July? Could this be the earliest cane ever to hit the U.S. motherland homeland mainland?

    Guys? I hope you are being sarcastic. If IIRC the earliest hurricane ever (in a year) was in January in 1938. AGW was really ripping back then. (That was sarcasm in case you could not tell.

  8. “Guys? I hope you are being sarcastic.”

    Well I guess I could have put in a tag to show I was being sarcastic, but I thought the “U.S. motherland homeland mainland” part was a dead giveaway. No?

    I have 2 weather rocks. One is well organized granite and the other is unorganized obsidian. At the moment they both claim “sunny.”

    As for the “great white fuzz” – an animation would show that there is movement and that is what those with experience “see” in the photo provide by the host (Thanks, A.).
    The concept is called cyclogenesis and the Wikipedia page says this “is an umbrella term for several different processes, all of which result in the development of …
    There, in the 3rd line, the word “cyclone” is a link. Go there for more background.

    Fairly simply, the great white fuzz at the southern end of the storm looks like outflow beginning. Tropical storms need upper level outflow to intensify, meaning that the rising air in the center of the forming storm has to be able to be evacuated in order for more air to enter the system at the bottom, which then rises into the outflow, which enables more air to enter the bottom and so on.
    As this process continues, other conditions being favorable, the speed of entry winds increases around the center strengthening the storm. Also look for bands of thunderstorms to begin to wrap around the center, a clear sign of strengthening. The big issue with tropical systems is their ability, when conditions are right, to intensify rapidly so while 40 mph winds seem innocent enough you must keep close watch because they can become 80+ mph winds fairly quickly.

    You might also note the small, thin line of clouds along the west coast of Florida. That is a line of thunderstorms formed by the sea breeze. They bring welcome cooling to the immediate area underneath and provide needed heavy rains for a short period of time. My plants love it.

    Yes, reading the latest discussion there is wind shear from the northwest, although that is supposed to weaken very soon.

  16. jones says:

    Jimbo, would you please happen to have a list of hurricane related predictions?

  17. “the earliest hurricane ever (in a year) was in January in 1938. AGW was really ripping back then.”

    OMG it’s worse than we thought. AGW can even go back in time, and cause hurricanes in the past. Truly, nothing is safe now.

  18. Dave says:

    I could swear Hurricane Agnes hit in June 1972, caused record flooding in Western New York.

    I bet Al Gore is on his knees praying for this baby to grow up and cause some damage.

  20. noaaprogrammer says:

    Cyclogenesis is also seen in storms heading westward across the Pacific off the coast of Mexico, but few seem to form typhoons. Is the surface water at that latitude of the Pacific cooler than the same in the Atlantic?

    Oh sure, the TS season starts in June, after all. There generally isn’t much activity until mid-August. I’d be quite happy if they moved the start of the season to July. The flurry of news coverage and safety tips that comes with the start of the season is long forgotten before the first storm develops.

    This is a pretty good summary of July activity, the 2009 outlook, and a good plot of TS tracks from storms that formed on July 1-15:

    ————————————————————————————————————————
    The waters in the Gulf of Mexico and the Caribbean typically hit the TS threshold of 80F in early June so there is the possibility of tropical storm formation at that time. Most of the early season storms form in this area as the waters of the mid and eastern Atlantic take longer to heat up. Of course weather doesn’t always behave the way we think it will.

    > I could swear Hurricane Agnes hit in June 1972, caused record flooding in Western New York.

    I was in Pittsburgh PA, barrels of whiskey were floating down the Allegheny River. Officials warned people not to get them, citing the risk of pathogens. That was roundly laughed at. The remnants stalled over central PA and produced massive destruction from all the flooding. At the time it was the costliest US tropical cyclone.

    After a day of steady rain I was bicycling home and it occurred to me that it might be Agnes, I hadn’t paid much attention since its first landfall. It was probably the next day that my housemates and went to the “point” where three rivers meet to look at the flooding around there.

    Like a lot of tropical cyclones, it’s not the wind (Agnes peaked at 85 mph), it’s the flooding. At least Arthur will zip off to the northeast, maybe brushing me and won’t bring much rain. It might make for an interesting day in the Canadian Maritimes.

  30. Tom Trevor says:

    Well , Tom in Florida (the other Tom who is in Florida, not me) claims a lot of great things for thunderstorms along the sea breeze front. But I say that the lighting that knocked out electricity here for a few second was not fun at all. Also the plants were not too happy with the huge downpour. I don’t think plants really like sea breeze front thunderstorms, yes they need the water, it makes up for the lack of rain from the winter, but in thunderstorms it comes all at once, I think plants would like it more steady. My grass is nice and green though.

  31. goldminor says:

    I was just looking at earth.nullschool and the cuurent conditions off of the Florida coast. I wanted to get a look at what was going on further up in the Atlantic, and I was somewhat amazed to see a huge rotation surrounding Iceland and a bit of the sea south of Iceland It looks to be around 10 to 12 times larger in area than the Florida circulation. I realize that it is not a hurricane, but it seems unusual…http://earth.nullschool.net/#current/wind/isobaric/850hPa/orthographic=-52.15,47.21,671

  32. D. Cohen says:

    The main thing to look for as a tropical cyclone starts to get “organized” is the formation of a small, circular eye-like feature at or near the center of the roughly circular mass of clouds. The diameter of the eye is typically — and very approximately — five to ten percent or so of the diameter of the storm’s overall cloud mass. The smaller the eye is compared to the diameter of the cloud mass, the more intense the storm. The further off to the edge the eye is, the more likely the storm is to weaken or reorganize with a new eye closer to the center. Reorganizing storms usually do not increase in intensity and may have their wind speeds drop.

    Not even close – try June 4 1966 for starters

    The circular wind pattern, eye and strong high level winds (that tear rising thunderstorm clouds apart so there is no lightning) have been visible for a day.

    Arthur still had not organised enough to destroy the lightning storms at 0900 UT.

    Must not forget Audrey, June 27, 1957. Made landfall as a Cat 4 at 145 mph.

    If it is a hurricane when it hits land, how many days will it have been since the last?

    “If this storm becomes a hurricane, that will be clear unambiguous proof of global warming”

    Also if it doesn’t become a hurricane.

    What are the chances Arthur will stay mostly at sea and move north towards New England once it gets done with the Outer Banks of North Carolina?
