FACTBOX: Forecasts for 2007 Atlantic hurricane season

(Reuters) - The U.S. National Oceanic and Atmospheric Administration on Tuesday forecast 13 to 17 storms for the 2007 Atlantic storm season and said as many as 10 will become hurricanes.

The forecast by the government's top climate agency is in line with those of other experts, who predict a busy season after a quiet 2006.

So far, no forecast predicts anything like a repeat of record-breaking 2005, when 28 tropical storms spawned 15 hurricanes, including Katrina. Following are the latest predictions for 2007:
