SCUBA PROGRAMS

Some of the Scuba Adventure crews headed out last night to attempt a second night dive for the week.  Several 2012 Scuba Adventure crews commented that they would have liked to have a second night dive during their week.  The current adjustment is a trial.  We are encountering multiple logistical challenges.  I think only three or four crews have been successful in logging two night dives this summer.  It may prove to be too much for the majority of our participants, dive staff, and captains.

I had an opportunity to sit and visit with one of our Scuba Liveaboard crews yesterday.  They were about halfway through their adventure.  They were tired but having a great time.  Scuba Liveaboard is one of our more arduous adventures.  Spending a week on a sailboat can be challenging.  The boat is ALWAYS in motion.  At anchor or at the dock the boat is still moving.  This alone can become physically and mentally tasking.  Logging as many as 15 dives in a week is exhausting.  Combining the two is for the die-hard diver.  We designed this program for more experienced divers.  It can be challenging for those ill-prepared.

The Scuba Certification crews are doing better since the weather has calmed down.  It is a real blessing to have Captain Bert Hubby, a PADI Course Director, driving the boat and providing advice to our scuba instructors.

TROPICAL WEATHER

One of the two tropic systems that has been sitting off the pacific coast of Mexico has upgraded to Tropical Storm Cosme and should become a weak hurricane today or tomorrow.  It is moving west into the open Pacific.

Dr. Jeff Masters of Weather Underground has not commented on anything tropical for several days.  That’s a good thing.  There is a tropical wave between Honduras and Haiti in the Caribbean but is being torn apart by high wind shear.  An area of dry air exists between Africa and the United States providing unfavorable conditions for severe tropical weather development.

As I mentioned yesterday or the day before, our next threat is expected to start in the Mexico/Central America region.

GULF / CARIBBEAN / EXTENDED FORECAST

For weeks now there has been a signal showing up indicating the end of June and early July as being a time conducive to rising air, low pressure, and rainfall in the Gulf/Caribbean region, and that is still the case.

Oftentimes in such a situation that stuff organizes into at least a tropical depression or storm, as has been the case with Cosme in the eastern Pacific, where conditions have already become favorable for development.

The question is whether there’ll be one in the Caribbean/Gulf next week. Models have been vacillating on that.

If there were to be one, there’s also a strong signal showing up in the steering pattern (model forecast map below for early next week), with the air flow and its jet stream meanders quite “amplified” over and near North America, and with much model consistency in this prediction: a strong ridge of high pressure aloft in the West, with very hot, dry weather — not good for drought/fires; a sharp trough of low pressure to the east of that; and a wet pattern with a lot of showers and thunderstorms from the eastern Gulf up the East Coast, in some places heavy rain falling on top of already very saturated soil.

Troughs like that dangling down over the Gulf provide a pathway for a tropical system to go up along or just ahead of it, so IF one develops, its track would depend on exactly where that trough is, and whether it would get into that pathway or sneak south of it to the west like Barry did.

For that to matter, first there would need to be a storm. We’ll be closely monitoring what the prospects are for that. Another possibility is that another one develops on the Pacific side, with or without one on the other side of Central America.

As you can see, the Gulf of Mexico and Caribbean Sea are currently very clear, with the exception of some minor storms on the west coast of Florida.

SCHOONER SIENNA BELLE

I did not not hear from Captain Rich yesterday.  “No news is good news.”  But, being dissatisfied with that assumption, I sent a text to Captain/Nurse Carol Beliveau.  She replied that Captain Rich had called her by satellite phone at 17:00, said all was good and they were about 36 hours from Beaufort, NC. 🙂

One Response to “NIGHT DIVES”

  1. Denny Webb says:

    Hey Steve, your comment on the SLA was correct, it is a busy week. After 9 years of providing SLA for Sea Base here are some of my thoughts. 95% of our crews are new divers. They chose the liveaboard because it sounded to them like the “do it all trip.” They get to dive and sail and fish and live on a boat for a week. The key to it all is finding what their expectations are and what will make that particular crew have the “adventure of a lifetime”. That can sometimes be harder than you think because the expectations of the most vocal adult leader may not be a fit for that crew. Communication is the key. For some crews it is 15 dives, for others it may be 10 with more time spent doing other activities. That is the nice thing about it, it is your trip and weather cooperating, you can “have it your way”.
