The general perception is that we've had much fewer than normal. AccuWeather warns that against being too hasty:
AccuWeather.com reports conditions have been limiting the intensity of tropical systems in the Atlantic basin so far this season, but the season is far from over.
Gustav was the first hurricane of the season, but it will not be the last.
On average, by the middle of September three hurricanes have formed. Yet, so far this year there has been only one, Humberto.
And don't forget about tropical storms:
While the number of hurricanes is running behind the average pace, the Atlantic is churning out an above-average number of tropical storms.
By the middle of September, the average number of tropical storms is six. So far this season, there have been eight, with a ninth system already in the works over the southwestern Gulf of Mexico.
