Hurricane Danny finally intensified Thursday morning into the first hurricane of the 2015 Atlantic hurricane season, well to the east of the Lesser Antilles in the central Atlantic Ocean.

Microwave satellite imagery indicates Danny’s convection looks to be more solidly organized around its center of circulation Thursday morning than it was Wednesday, notes hurricane specialist, Michael Lowry.

Danny’s hurricane-force winds extended up to only about 10 miles from the center of circulation as of the 11 a.m. advisory from the National Hurricane Center, a tiny hurricane-force wind field.

Small circulations such as Danny are prone to sudden changes in intensity, which can be difficult to forecast.
