Compact Hurricane Danny is swirling along in the central Atlantic and is doing pretty much what forecasters thought it would do.
At a category one storm, Danny has estimated winds of 74-95 mph. It is still heading to the west-northwest. On this pace, Danny will affect the northern Leeward Islands by late Sunday.
Danny is fighting an uphill battle as it heads west. It will encounter drier air through a greater depth of the atmosphere. Also, stronger winds in the upper atmosphere (shear) will begin to affect this storm. Also, interaction with the the terrain features of Puerto Rico may also disrupt Danny. For all of these reasons, the official forecast has Danny weakening to a tropical storm by Sunday.
