Tropical Storm Sebastien forms with 11 days left in hurricane season


The disturbance that was east of the Leeward Islands for the past 7-10 days has finally developed into the 18th named storm of the season: Sebastien.  It is not a threat to land.  The last time we reached the "S" storm in a season was 2012 (Sandy).

As I mentioned in yesterday's post, Sebastien could easily be the 9th storm this season to last for two days or less, a remarkably high percentage of weak, short-lived storms.  With nearby dry air and strong vertical wind shear approaching by Wednesday, it won't be a named storm for long.


While the official hurricane season starts on June 1 and ends on November 30, nature does not always obey those artificial bounds -- so while this is likely the last storm of the season, we can't say for certain just yet!
