Government hurricane experts are predicting a weaker Atlantic tropical storm season than they had expected.
The report comes a day after professor William Gray at Colorado State University downgraded his forecast. He's one of the world's top forecasters for tropical storm activity.
Experts agree that there will be no more than 10 tropical storms in the Atlantic, Caribbean and Gulf of Mexico this year. That's three fewer than they had anticipated a few months ago.
Forecasters say the change is due to a stronger El Nino phenomenon.
El Nino is a warming of a large area of the Pacific off the coast of Chile. The warming changes the routes of jet streams that affect the world's weather.
