Tropical Storm Alvin dissipated, new low pressure system is forming
Alvin had strengthened to a Tropical Storm on May 15, 2013 and now has weakened and is considered a Post-Tropical Cyclone. With the excessive wind shear and cooler water, the storm has dissipated into just a weak low pressure.
According to Tropical Weather Outlook by US National Hurricane Center, an area of low pressure associated with the remnants of Alvin is located about 800 miles southwest of Manzanillo, Mexico. The system continues to produce a large area of disorganized shower and thunderstorm activity.
The system has a low 20% chance of becoming a tropical cyclone again during the next 48 hours as it moves west-northwestward around 10 mph. Strong upper-level westerly winds are expected to inhibit any significant development.
