While things have picked up in the Eastern Pacific and Atlantic, they are waning in the Western Pacific. Over the past few days, the site has been reporting on Tropical Storm Dujuan. On Saturday, there were indications that Dujuan would become a typhoon, and possibly affect Japan. However, on Sunday the forecast didn’t have Dujuan strengthening to anything more than a storm, and this morning, it has weakened to a depression.
According to the latest information from the Joint Typhoon Warning Center, Dujuan now only has winds of 30 knots, or 35 miles per hour with gusts reaching 40 knots, or 45 miles per hour. The cone of uncertainty takes Japan completely out of the picture as Dujuan is projected to move far to the south of the main island. The intensity forecast calls for Dujuan to remain at this intensity for the next 48 hours, or so, and then strengthen to have 45 knot, or 50 mile per hour winds by 72 hours. This increase in intensity is expected from a transition into an extratropical cyclone.
Looking at the latest infrared satellite imagery of the depression, it is easy to see that the center of circulation is pretty much exposed at this point. Much of the convection associated with the system is on the southern and western side of it. As Dujuan tracks to the Northeast, it will begin to encounter greater amounts of wind shear, which will assist in making it lose its tropical characteristics. Meanwhile, in the Central Pacific, conditions continue to be relatively tranquil over the Hawaiian Islands as shower and thunderstorm activity passes to the south of the 50th state.
According to the Central Pacific Hurricane Center in Honolulu, Hawaii, no tropical formation is expected through early Wednesday morning. So far this season, there have been 6 depressions, 5 storms, and 2 hurricanes in this basin. Four of the tropical cyclones that have traversed this region originated in the Eastern Pacific.
