In the final days of the 2011 hurricane season, the National Hurricane Center revised the status and strength of a couple of tropical systems from earlier in the season.

A brief storm system in the northern Atlantic in the early portion of September came and went without official tropical identification.  However, after a series of reviews of various data, NHC meteorologists deemed the system had developed enough to be classified as a tropical storm.  This unnamed storm raises the tally of tropical storms officially to 19 for the 2011 season.

Tropical Storm Nate, which wandered in the Bay of Campeche in the second week of September, reached hurricane level for a brief period of time on Sept. 8.  The upgrade was based, in part, on observations from nearby oil rigs that experienced category-one hurricane-force winds several times over a span of about 12 hours on Sept. 8.

Nineteen tropical storms matches the same number of tropical storms that formed in 2010.  The count is well above the average of 11 named storms per season.  Seven of the 19 storms this year became hurricanes, and three of those reached major hurricane status.
