TD Parma back over Philippines – again; Melor extratropical and offshore; development near Guam

by Tim Trice on October 8, 2009 · 0 comments

in West Pacific

Melor is finished as a tropical system.  However, the storm left behind considerable damage.  Hundreds of thousands are without electricity today across Japan.  In addition, two are reported dead by the Associated Press; a motorcycle rider who hit a downed tree and another person killed by a falling tree.

Parma is now a tropical depression and is making a third crossing over the northern Philippines.

A tropical depression is also developing just to the west of the Mariana Islands.  The next name available is Nepartak.

Extratropical storm Melor

Melor was declared extratropical early this morning as the system moved back offshore into the west Pacific.

The remnants of Melor are located 130 miles south of Cape Erimo, Japan as of a 08/0900 UTC position estimate from the Joint Typhoon Warning Center.

In addition to the two killed, Melor has injured over 30 and forced the evacuation of over 11,000.

Amazingly, the AP reports over 2 million commuters were stranded along the rail lines and highways.  (Why trains were running during a typhoon and flash-flooding conditions; I have no idea…)

Tropical Depression Parma

Tropical Depression Parma moved back inland over Luzon, Philippines.  This will mark the third trip Parma has made across the region.

Parma is under the steering current now of a subtropical ridge centered over China.  This motion will take Parma back into the South China Sea early tomorrow morning.

Tropical Depression Parma - Forecast Advisory

As you can see in the graphic above, only slight strengthening is forecast and Parma will likely come ashore Hainan, China as a minimal tropical storm.  It seems the reasoning the system isn’t expected to strengthen much is due to the rugged terrain disrupting the circulation, despite favorable upper-level conditions.

The area of disturbed weather just to the west of the Mariana Islands is getting better organized and the JTWC has indicated they will likely initiate advisories later today if the organizational trends continue.

The system has fair outflow to the north and is under an area of pretty weak wind shear.

Currently, the JTWC estimates sustained winds near 25kts (29mph or 46kph) with a central pressure of 1002mb (29.59in).
