UPDATE at 6:00 a.m. PDT Friday

Alvin, which had strengthened to a Tropical Storm on Wednesday has weakened and is now considered a Post-Tropical Cyclone. With the excessive wind shear and cooler water, the storm has dissipated into just a weak low pressure.

Wednesday marked the start of the 2013 Eastern Pacific hurricane season, and, right on time, the first tropical depression and subsequent tropical storm of the season has formed.

Tropical Depression One-E, which formed Wednesday morning EDT, strengthened into Tropical Storm Alvin late Wednesday afternoon with warm ocean water and light wind shear in place.

An area of unsettled weather crossed the eastern Pacific Ocean several hundred miles to the west of Panama and well south of Mexico to become better organized Wednesday, prompting the upgrade. Expert Senior Meteorologist Dan Kottlowski stated, "It is not uncommon for there to be an area of possible tropical development when the Eastern Pacific hurricane season begins."

Alvin currently is not expected to become the first hurricane of the season in the basin. The combination of cooler water and strong wind shear will likely keep the storm from strengthening.

No landmasses are expected to impacted by Alvin as it remains over the open Pacific Ocean.
