We're halfway through the Atlantic Hurricane Season and so far, not a single storm has developed into a hurricane.
Private and government forecasters had projected an above average year for hurricanes.
The last time we made it this deep into a season without a hurricane was in 2002 when there was a moderately strong El Nino. Still, the season is on track with tropical storms. During an "average" season, the 5th tropical storm of the season does not show up until August 31, but this year the season's fifth storm Erin, developed on August 15.
Phil Klotzbach with the forecasting team at Colorado State University says a few waves coming off Africa have developed, but then they've died very quickly, "and that seems to be due to the fact that we've had quite a bit of dry air as well as vertical shear."
"So it seems to be that those two factors in combination have been what's really caused the season to get off to the slow start that it's gotten off to so far," says Klotzbach.
