Hurricane Epsilon - Weakening and Dissipation

Weakening and Dissipation

On December 6 the hurricane turned to the south and southwest. As it did so, Epsilon passed beneath a mid-level trough that sheltered it from the wind shear. After weakening during the evening, the convection redeveloped around the large and distinct eye in the daytime, a process Epsilon had done repeatedly in its duration. However, late on December 7, an approaching trough began increasing wind shear over the system, displacing the convection from the center and causing the eye to dissipate. After maintaining hurricane status for five days, Epsilon weakened to tropical storm status about 920 mi (1480 km) southwest of the Azores.

Once weakened to a tropical storm, Epsilon began rapidly deteriorating. On December 8, it was downgraded to a tropical depression as the convection had totally dissipated. The NHC issued their final advisory on Epsilon at 1500 UTC that day, after the cyclone consisted of a tight swirl of low clouds with no convection. On issuing the last advisory, Lixion Avila remarked, "I hope this is the end of the long lasting 2005 hurricane season." There was ultimately one more tropical storm – Zeta.

Late on December 8, Epsilon transitioned into a remnant low pressure area. The remnant circulation elongated in advance of a frontal zone, and it dissipated late on December 9. The front absorbed the remnants the next day.

Famous quotes containing the words weakening and, weakening and/or dissipation:

    What is wanted—whether this is admitted or not—is nothing less than a fundamental remolding, indeed weakening and abolition of the individual: one never tires of enumerating and indicting all that is evil and inimical, prodigal, costly, extravagant in the form individual existence has assumed hitherto, one hopes to manage more cheaply, more safely, more equitably, more uniformly if there exist only large bodies and their members.
    Friedrich Nietzsche (1844–1900)

    The more specific idea of evolution now reached is—a change from an indefinite, incoherent homogeneity to a definite, coherent heterogeneity, accompanying the dissipation of motion and integration of matter.
    Herbert Spencer (1820–1903)
