MIAMI (AP) — The National Hurricane Center has added one subtropical storm to last year’s tally of tropical weather.

Forecasters said this week that as part of a routine review of data from the 2013 Atlantic hurricane season, a short-lived low that developed south of the Azores in early December was determined to be a subtropical storm. The December storm was not given a name.
