The National Hurricane Center's cone of uncertainty will remain almost the same size during the 2014 storm season as it was in 2013.
However, the three- four- and five-day periods of the cone - intended to show the potential area that a storm could roam - will be slightly skinner.
That reflects little overall improvement in predicting the paths of storms since 2009, as size of the cone is calculated by averaging forecast track errors over the past five years.
Just the same, the center reduced the diameter of the three-day period of the cone by about 7 miles, the four-day period by about 16 miles and the five-day period by about 7 miles.
The cone is constructed with a series of concentric circles, one for each forecast period through five-days.
The circles for the 12, 24, 36 and 48 hour periods of the cone will remain unchanged.
How the hurricane center fared last year in its forecast accuracy will be released in an upcoming report, center spokesman Dennis Feltgen said.
He noted that calculating the paths of storms during the 2013 season wasn't easy because many of the storms were weak.
"There weren't a whole lot of long-lived storms last year," he said.
