Loop Current taking oil farther across Gulf of MexicoAccuWeather.com reports the Loop Current, a warm ocean current in the Gulf of Mexico, continues to transport part of the massive oil slick over the north-central Gulf of Mexico southeastward toward Florida. Concerns remain about oil being drawn into the Gulf Stream and perhaps heading up the Atlantic Seaboard.
Based on satellite imagery from early in the week, it appears a significant part of the oil slick is tearing away and being drawn well to the south in the east-central Gulf of Mexico this week.
Officials have closed more of the Gulf to fishing as a result.
The speed of the current, which can reach several miles per hour, can carry part of the oil much more swiftly than waters over the slight, aimless drift of the north-central Gulf and light surface winds.
In addition to the concern now for oil showing up in great quantities in the Keys, the Florida West Coast, Cuba and the Yucatan Peninsula of Mexico, part of the slick could be drawn into the Gulf Stream through the Florida Straits then perhaps northward to part of the Atlantic Seaboard of the United States.
At the same time, more and more of the slick is reaching the shoreline of Louisiana and seeping into bays, estuaries and tidal marshes, due to recent southeast winds over much of the past couple of weeks.
Winds will remain fairly light out of the east-southeast over the central and eastern Gulf of Mexico through this weekend. In response to the light winds, seas will remain relatively calm with wave heights averaging 1 to 2 feet.
Though not strong, the winds will remain capable of funneling most contaminants into Louisiana.
While the Loop Current and the Gulf Stream are permanent currents, they change shape and orientation, depending upon the season as well because of fluctuating wind and temperature patterns.
The currents are simply part of the massive engine of the world's oceans, which transport, remove and, in turn, help to balance the heat budget of the earth.
Small eddies along the edges of the Loop Current and Gulf Stream, form, dissipate and meander, making precise forecasts of the long-term oil slick drift nearly impossible.
While placement of additional booms are encouraged for other shores along the Gulf of Mexico at this time, it should be understood that the booms are not fool-proof.
Vigorous wind and wave action in the vicinity of large storms, such as hurricanes or tropical storms, and small-scale coastal thunderstorms can render these measures inefficient.
Concerns are not limited to the surface and shorelines, as the larger the surface area covered by the slick means a larger area of the Gulf bottom may also be affected.
The developments over the past few days have shown that an oil slick can travel great distances before breaking up, thanks to fast-flowing currents.
