Clouds, unstable Loop Current making oil spill prediction difficult

It's cloudy over the Gulf of Mexico today, so it is difficult to tell how far into the Loop Current the Deepwater Horizon oil has penetrated using visible satellite imagery. Satellite imagery yesterday from NASA's MODIS instrument confirmed that a tongue of oil moved southeast from the Deepwater Horizon oil spill and entered the Gulf of Mexico's Loop Current. However, Synthetic Aperture Radar imagery from the European Envisat satellite posted at ROFFS Ocean Forecasting Service shows that while some of the tongue of oil that entered the Loop Current appears to be circulating southwards towards the Florida Keys, perhaps 80% of the oil in this tongue is caught in a counter-clockwise circulating eddy along the north side of the Loop Current. This oil may eventually circulate around and enter the Loop Current, but not for at least three days.


Figure 1. Oil spill forecast for this Thursday night as simulated by the 6pm EDT Monday May 17 runs of the Navy Gulf of Mexico HYCOM nowcast/forecast system and the Global HYCOM + NCODA Analysis from the HYCOM Consortium. See the University of South Florida Ocean Circulation Group website for more information. There are considerable differences between the two models, due in part to the fact that they have much different depictions of the sea surface temperatures (SSTs) and ocean currents at the beginning of their runs. The warm Loop Current is visible as the red colors of the SST field that form a heart-shaped area in the Gulf.

How long will it be until oil reaches the Keys?
Once oil gets into the Loop Current, the 1 - 2 mph speed of the current should allow the oil to travel the 500 miles to the Florida Keys in 5 - 10 days. Portions of the Loop Current flow at speed up to 4 mph, so the fastest transport could be 4 - 5 days.

How much oil has made it into the Loop Current?
According to the latest trajectory forecasts from NOAA, the tongue of oil flowing southwards has, at most, "light" concentrations. The oil will grow more dilute as it travels the 500 miles to the Florida Keys, and most of the oil appears to be caught in a smaller counter-clockwise rotating eddy on the north side of the Loop Current. My present expectation is that the oil entering the Loop Current this week will cause only minor problems in the Keys next week. However, there is a lot of uncertainty regarding how much oil will get to the Keys, and we cannot rule out the possibility of an ecological disaster in the fragile Keys ecosystem.

How is the Loop Current changing?
The Loop Current has been highly chaotic and unstable over the past week, making it difficult to predict how the ocean currents near the spill will behave. According to ROFFS Ocean Fishing Service, which has done a tremendous job tracking the spill, the Loop Current surged 7 - 10 miles northward Sunday and Monday. The Loop Current has gotten more contorted since Friday, and may be ready to cut off into a clockwise-rotating Loop Current Eddy. This process occurs every 6 - 11 months, with the clockwise-rotating ring of water slowly drifting west-southwest towards Texas. The last eddy broke off ten months ago, so the Loop Current is due to shed another eddy in the next few months. The latest 1-month forecast from the U.S. Navy does not predict an eddy forming, but these forecasts are not very reliable. If a Loop Current Eddy does break off, oil getting entrained into it might orbit the center of the Gulf of Mexico for many months inside the eddy. However, this eddy will probably reattach and detach from the main Loop Current flow for at least a month following when it breaks off, so oil will continue to flow through the Keys during this initial month.

When will the flow of oil into the Loop Current shut off?
Winds over the oil spill location are expected to be light and onshore at 5 - 10 knots through Saturday. This means that the chaotic contortions of the Loop Current will primarily control how much oil gets into it, making it difficult to predict when the flow will shut off. The long range (and thus unreliable) forecast for next week from the GFS model calls for a continuation of light winds over the eastern Gulf of Mexico. Thus, the flow of oil into the Loop Current could occur intermittently for several weeks.

Who besides the Keys are at risk next week from the Loop Current oil?
As I discussed in an earlier post, the coast of Southwest Florida from Tampa Bay to the Everglades is a "Forbidden Zone" for surface-based transport of ocean water to the coast, and is probably not at risk from this week's Loop Current oil. The northwest coast of Cuba east of Havana and the coast of Southeast Florida from the Keys to West Palm Beach are at the most risk. The western shores of the western-most Bahama Islands and the U.S. coast north of West Palm Beach northwards to Cape Hatteras are at slight risk. It would likely take ocean eddies 2 - 9 weeks to transport the oil to these locations, and the oil would probably be so dilute that ecosystem damage would probably be minor, at most. At this point, I see no reason for cancellation of vacation plans to any of the beach areas that may potentially be affected by the oil.

What is happening to the plumes of oil at depth?
Two research missions over the past week have detected substantial plumes of oil at depth, moving to the southwest. The deepest of the these plumes, near the site of the blowout at 5,000 feet depth, is in a region of slow ocean currents and has not moved much. At depths closer to the surface, the currents get stronger, and oil within a few hundred feet of the surface--if there is any--could potentially have been dragged into the Loop Current. At this point, we don't have a very good picture of how much oil is at depth and where it might be headed.

The tropics
For those of you interested in a detailed look at the early season tropical weather outlook, consult the excellent wunderblogs of StormW and Weather456, who are now featured bloggers for the coming hurricane season. We have some models predicting a possible subtropical storm off the U.S. East coast next week, but this does not appear to be a significant concern for land areas at this time. More concerning is the possibility that an area of disturbed weather will develop across the Western Caribbean late next week. While wind shear will likely keep anything in the Western Caribbean from developing, several models are predicting that this disturbance may bring major flooding rains to earthquake-ravaged Haiti late next week.

I'll be back with a new post Wednesday afternoon.

Anything from Bastardi on next week's possible tropical development?


He's out of town today, so no extensive posts, but he is just as concerned about these two possible developments as we are. He also seems to be in the camp of the westward retrogression of the Bahamas low that the Euro shows, as am I. The Euro usually handles these complex trough-split situations better than the GFS.

Quoting Levi32:


Yes that's what I mean, which is what the models have been showing this whole time, a classic subtropical low if it were to retrograde westward. However, the trough-split low will only be getting weaker, and up until now every run of the Euro had this surface low weakening and fading away by the time it makes it to Florida due to it not being able to sustain itself without the cold dry pocket aloft. This new run suggests that it may be able, with the aid of the warmer SSTs of the Gulf Stream, to warm its entire core and begin sustaining itself via purely tropical processes. In other words, at 240 hours on the 12z Euro this may no longer be subtropical, but tropical.


Perfect, was thinking the same thing. In a few days we will get the ECMWF CPD of this run.

WEDNESDAY 6:30 A.M.
A CLASSIC SUMMER WEEK NEXT WEEK... HEAT AND THE TROPICS?

A quick post as I am on the road again, for an appearance in Phoenix this evening. I will try to post from Phoenix this afternoon. But just to let you know a wild week is in front of us next week with three aspects that deserved attention: 1. the major cold into the West; 2. a heat wave from the northern Plains into the interior Northeast; and 3. the threat of one or two developments in the tropics, a subtropical development east of the Bahamas that could swing west toward the Southeast coast, and the more conventional type early season development in the western Caribbean that would drift northeast as this went by to the north. Very complex, but with the huge high in the north Atlantic near 40 north, rather than farther south, it means easterlies are stronger than normal in the western Atlantic farther north than normal, lighter than normal farther south, and this should cause the "buildup" of heat needed to lower pressures in the southwest Atlantic and the Caribbean.

Ciao for now

Possibly. If that's true this would be the first model run that actually expects the system to be able to strengthen via purely tropical processes with no help from its upper trough-split low which would be weakening the whole time.

Jean Lafitte cancels seafood festival due to Gulf oil response

Posted on May 19, 2010 at 1:28 PM

JEAN LAFITTE, La. The Jean Lafitte Seafood Festival has fallen victim to the Deepwater Horizon oil leak in the Gulf of Mexico.

Officials called off this year's festival because of ongoing response and impact to the local seafood supply.

We want the citizens to know that Jefferson Parish will continue to monitor the plans in response to the BP Horizon oil spill to ensure the protection of this community, Jefferson Parish Councilman Chris Roberts said.

This year's festival was scheduled for July 30 through Aug. 1.

Canceling this event is a major disappointment for festival goers who attend this festival every year, but we need to focus on the containment and recovery from this spill, Lafitte Mayor Tim Kerner said.

The Euro end of the forecast run at 240 hours also shows a longwave trough digging southward over the northeastern US. It has been long hinted by the models that even if the Bahamas low retrogrades west, it would eventually be picked up a few days later by this next trough.
