Hurricane Hunters to check out remains of Fred; 98L more organized
A tropical disturbance (98L), is located midway between Africa and the Lesser Antilles Islands. This disturbance has shown a modest increase in heavy thunderstorm activity over the past day. This morning's QuikSCAT pass showed an elongated circulation, with top winds around 30 mph. Wind shear is low, 5 - 10 knots, and Sea Surface Temperatures are 28°C, which is about 2°C above the 26°C threshold needed to support a tropical cyclone. There is a large amount of dry air to the north and west of 98L, and this dry air is interfering with development.
Wind shear over 98L is expected to remain in the low range, 5 - 10 knots, through Sunday evening, according to the SHIPS model. This may allow the storm to organize into a tropical depression, assuming it can fight off the dry air that surrounds it. By Monday, the SHIPS model predicts shear will increase to the high range, 15 - 30 knots, so in is unlikely 98L will become anything stronger thatn a weak tropical storm over the coming 5-day period. The models predict that a strong trough of low pressure will turn 98L to the northwest and then north beginning on Monday, with the result that 98L misses the Lesser Antilles Islands by at least 500 miles. NHC is giving 98L a high (greater than 50%) chance of developing into a tropical depression by Monday. At this time, it does not appear that 98L will ever threaten any land areas.
Fred-ex
The remains of Hurricane Fred are still spinning away about 700 miles east of Florida. There has been a modest increase in heavy thunderstorm activity on the south side of Fred's circulation over the past day, but high wind shear and dry air have kept the thunderstorms from building over Fred's center. Wind shear is moderate, 15 - 20 knots, and there is substantial dry air surrounding ex-Fred on all sides. This morning's QuikSCAT pass showed top winds of 30 mph.
None of the computer models develop ex-Fred, and conditions for development are expected to remain marginal over the next three days, with wind shear of 15 - 20 knots and plenty of dry air around. Most of the models predict ex-Fred should move over Florida on Tuesday, but steering currents may weaken early next week, and ex-Fred could end up slowing down and turning northwest towards South Carolina. A hurricane hunter aircraft this afternoon was cancelled.

Twenty years ago today
On September 19, 1989, Hurricane Hugo moved away from Puerto Rico, and headed northwest at 15 mph. An upper-level low over Georgia, in combination with the steering currents imparted by the Azores-Bermuda High, were responsible for the northwesterly motion of the storm. Wind shear from strong upper-level winds continued to weaken the hurricane, and Hugo diminished to a Category 2 hurricane with 105 mph winds.

I'll have an update this afternoon if there's any major developments to report.

HaHA Baha! I finally beat you at something. Look at post 1184. Are these questions making you a little sea-sick, like I am?
Actually the -1s going across there means the model wasn't run specifically on Fred that day... Model wasn't run.. there is no error.

I wonder if Floridians are putting up their shutters tonight?
"Storms change names from ATL to PAC because it is a different basin. Storms that pass from EPac to CPac to WPac generally keep the same name. Best example I can remember is the longlived hurricane John of 1994. Here is what I found at wikipedia abt this storm."
Thanks for the info, I didn't know, that as althought it is the Pacific Basin as a whole.
As to whether since we had East Pacific, Central Pacfic, and Far East Pacific Cyclone offices, as to whether the East/Central might be different as far as naming goes from that of the Far East Pacific. Thankx Again! :-)
Have they started evac'ing your area for Cat 5 Fred yet?
Yup...they all headed to Tennessee and points north. I've boarded up and will be leaving early AM.
Wow.. You are taking it seriously, evacuating all the way back to the United States...
A - 3
B - 6 (Majority = Final Answer)
C - 3

Yup...we're lettin em have it.
He's the only one left in south Florida. He's sitting in a lounge chair on the beach waiting for it.
Want to look over the answer again Allstar?
and if this was to happen, you would say it would go to the eastern or western side of the GOM?
Ummm. The j/k at the end means JUST KIDDING. Ike and I were having a little tit for tat...
Since 1953, 73 storms have had their names retired. Of these, two (Carol and Edna) were reused after the storm for which they were retired but were later retroactively retired, and two others (Hilda and Janet) were included on later lists of storm names but were not reused before being retroactively retired. Historical records are unclear on the status of Gracie from the 1959 season. The official NHC site does not report Gracie as a retired name,[2] but it is widely referred to as retired, including by other official sources.[3]
If all the names on a season's normal list are used up, storms are then named after the letters of the Greek alphabet (Alpha, Beta, Gamma, etc.) Unlike the normal names, these cannot be retired. If a storm with a Greek name manages to reach the strength and have the impact that would otherwise lead to retirement, the Greek letter would be listed among the retired names with a footnote stating that the name would still be in use for future storms.
Since 1953, the following seasons have had no names retired from that season: 1953, 1956, 1958, 1962, 1968, 1971, 1973, 1976, 1978, 1981, 1982, 1984, 1986, 1987, 1993, 1994, 1997 and 2006.
Count em 18 not 17
Did you miss the whole Ike thing last year? Really...get some help...

You could be right, even though it's yet again blowing new convection, it just isn't going. It would put the blog to rest :)
ONLY ECHOES SHOWING UP ON RADAR OVER EC FL AND ADJACENT ATLC ARE
NON-PRECIPITATION ECHOES AT THIS TIME. WHAT APPEARS TO BE A SMOKE
PLUME ACROSS NW VOLUSIA/N LAKE AND EASTERN MARION FINALLY APPEARS TO
BE THINNING. AND ECHOES OFFSHORE VOLUSIA COUNTY ARE LIKELY CHAFF.
HAVE REMOVED RAIN CHANCES FOR THE INTERIOR BUT KEPT A 20% POP FOR
THE COAST AS ADDITIONAL SHOWERS SHOULD REDEVELOP OVER THE ATLC
PREFERABLY ALG CONVERGENT LINES...AND ONSHORE FLOW SHOULD BRING A
FEW TO THE COAST.

I'm using restraint in not ranting about having clouds of god knows what being sprayed about.. Wonder if it has anything to do with Fred-ex..
Yeah, the colors in South Florida have been neat. Although tonight it looked like Tornado weather. The color was so surreal.
It was a break from the RAIN ALL DAY LONG here.
lets see how it looks after it
