A quiet week for the Atlantic; another typhoon for the Philippines?

There are no threat areas in the Atlantic to discuss, and none of the computer models is calling for tropical storm formation over the next seven days. This should be a quiet week in the region we need to be most concerned about for a late-season hurricane--the Western Caribbean. Wind shear is forecast to be marginal for tropical storm development this week, and most of the Caribbean is very dry. However, next week moisture will be on the increase and wind shear is expected to be low enough to support tropical storm development, so we will need to be more alert for tropical storm development then. I have a sense that this hurricane season may not be over yet. Wind shear hasn't risen to the high levels we usually see by this time of year, and the waters are still very warm in the Western Caribbean. The past ten years have seen five hurricanes (four of them major hurricanes) form in the Caribbean later than today's date. The five storms were Category 4 Paloma, which became a hurricane on November 7, 2008; Category 1 Noel, which became a hurricane on November 2, 2007; Category 3 Beta, which became a hurricane on October 29, 2005; Category 4 Michelle, which became a hurricane on November 2, 2001; and Category 4 Lenny, which became a hurricane on November 15, 1999.

Another typhoon for the Philippines?
The typhoon-weary Philippine Islands have a new worry--Tropical Depression 23 has formed east of the islands, and appears likely to develop into a typhoon that will threaten the Philippines this weekend. The Philippines got a major reprieve this past weekend, when Super Typhoon Lupit weakened and swerved out to sea unexpectedly, missing the islands.

Next post
I'll have a new post on Tuesday, when I'll present the forecast for winter in the U.S.

Good posts Boondog. They're showing up at about the same time I'm hearing of it on nasatv. Very quick.

I have a question for anyone who wants to answer in Post 605 I read this: "The two recent warm years, both 1998 and 2005, were El Nino years."

Maybe this is a stupid question but If 2005 was an El Nino year why did we have so many storms? We are in an El Nino year and I thought this decreased Atlantic storms..I am still learning.

15-20 minute weather window (if verified) in about 50 minutes

now everyone is keeping their fingers crossed.

helos will be refueled in the time frame of this weather no go and be operational by the new weather window.

5 min standby for weather recon

no more talk about the frieghter. Now a stupid cloud is holding us up.


A complicated machine and procedure. What did they say during Apollo, even if 99.9% of everything goes right, it would still mean about 10,000 other things went wrong?

mik you are right. range control is getting their ass chewed out right now I bet.

9:49 is the new launch time. They are going foward even with the ship in the box.


Good deal.

That is a funky looking spacecraft ain't it Boondog? I first saw it on a tour of KSC for the STS-126 launch last Dec. Wih I was there for this one - bound to be spectacular.

UPDATE
There's a cargo ship in the "danger box" - declaring a NOGO for now...

639. ya know, i was thinking the same thing when i realized the GLDH reintensified to a hurricane after passing over North Carolina and stayed a hurricane that far north in the Atlantic!

of course, the world will never know!


Someone correct me if I'm wrong, but isn't the Labor Day Hurricane still the most powerful TC in recorded history (via pressure) to ever make landfall anywhere on earth?

cord away

Idon't know guys and gals looks top heavy to me =(

Hoping for a sucessful test but just looks top heavy. Like once the payload gets up there the rotational pivot point is above the first stage booster segment. Meaning any thrust loss in any axis would cause a loss of attitude control. Am I right? From what I understand there is no thrust vectoring its basically light the fire and hang on. Correct?

Watching it on NASA TV even though it says educational right now.

Keeping my fingers crossed.

LOL mission update.. cord holding nose cone sheeth is stuck, might have to "cut the cord" their words not mine

Probe cover has been removed, but is caught on something, but no big deal apparently...

Flight poll...everyone says ready.

Wonder what '35 was as far as ocean temps, el nino, la nina, etc...?

Yesindeedy.

Now talking about a "slight adjustment" in liftoff time...

Sounds like they're comfortable with the load calculations based on UL winds. Still go for a 9:24am launch...

Good Morning from the Florida Big Bend. Nasty cells of t-storms head towards the FL Panhandle this morning from off-shore. Keep alert in the Panhandle and Big Bend today for possible tornadoes (keep your NOAA radios handy) as some waterspouts have already been seen offshore of Destin this morning.

They don't want the "5-hole probe" (that is what they're saying right?) to get wet. Hoping to beat the approaching shower...


Ike, are you able to see launches from your location?

I'm so bored I went back to the year 1900. There's been no hurricane to strike the USA west of the state of Florida in November.


1935 had hurricane 6 hit Florida in November...

Sounds like the only real issue with the launch is the concern over upper-level winds. Still, they're talking about taking the probe cover off within the next 15 minutes...

I just looked this up at noaa, should have posted it last night when the subject first came up:

(3) When did the earliest and latest hurricanes occur? The hurricane season is defined as June 1 through November 30. The earliest observed hurricane in a year in the Atlantic was on March 7, 1908, while the latest observed hurricane was on December 31, 1954, the second “Alice” of that year which persisted as a hurricane until January 5, 1955. Zeta of 2005 was the second latest tropical cyclone to form, just six hours ahead of Alice 1954. The earliest hurricane to strike the United States was Alma which struck northwest Florida on June 9, 1966. The latest hurricane to strike the United States was late on November 30, 1925 near Tampa, Florida.

Hurricane Kate in 1985 was the only hurricane to hit the USA in November, going back to 1950...1 in 60 years....

Interesting fact...although not that surprising....there has been no hurricane or tropical storm to strike the USA in November this decade.


Morning Ike, I love hurricane history, tell us more...
