90.3 WBHM Birmingham--Hurricane forecasters are adjusting down their predictions for this fall. It was supposed to be an active season - but so far, not much to talk about, at least here in Alabama.

Over in Georgia, researchers are taking a close look at the size of hurricanes. In an article published in the latest issue of Geophysical Research Letters, Judith Curry and her colleagues at the Georgia Institute of Technology suggest that as hurricanes get larger they spawn more damaging and deadly tornadoes. Curry tells WBHM's Tanya Ott that since the 1950's there's been a 35% increase in the size of hurricanes and that translated to an almost doubling in the number of tornadoes.

The research is published in the September issue of Geophysical Research Letters.
