"For the record, we're up to 28 storms"

Make That 28 Tropical Storms Last Year

Associated Press — Wed Apr 12, 5:00 PM ET :: ORLANDO, Fla. — Nearly five months after the record-shattering 2005 hurricane season ended, the summer of storms suddenly grew bigger by one. Upon further review of months-old weather records, the National Hurricane Center on Wednesday added a 28th storm to the season, which officially ended Nov. 30, 2005. The center added an unnamed subtropical storm that briefly popped up in early October and meandered around the Azores, the island chain west of Portugal. Its top winds reached about 52 mph, but it was far from normal tropical waters and wasn't immediately counted as a tropical storm. Looking at data months later, meteorologists decided it had tropical characteristics and should be included with more notable names such as Katrina, Rita and Wilma. The unnamed storm bumped the total from what had been a record 27 storms to 28, center director Max Mayfield told the annual National Hurricane Conference. The old record of 21 storms was in 1933.

An upper-level low formed just west of the Canary Islands on 28 September and moved generally westward for the next two days. A large but transient burst of convection developed near the low on 30 September, accompanied by the formation of a surface trough. The complex system moved generally westward to west-northwestward into a more unstable air mass, which allowed sporadic convection to develop. Surface observations and satellite cloud-motion winds indicate a broad surface low formed within the trough late on 3 October about 400 n mi southwest of São Miguel Island in the Azores. Convection increased in association with the surface low, and it is estimated that the system became a subtropical depression around 0600 UTC 4 October.

The depression turned northeastward in the warm sector ahead of an approaching cold front associated with a large non-tropical low northwest of the Azores. Additional development occurred, and it is estimated that the cyclone became a subtropical storm around 1200 UTC 4 October. The system reached an estimated peak intensity of 45 kt as the center passed through the eastern Azores later that day. The cyclone turned north-northeastward and merged with the approaching cold front early on 5 October. Late that day, the remains of the subtropical storm were absorbed by the non-tropical low. That low would evolve into Hurricane Vince a few days later.
