Track of TD 13W

Tropical Depression 13W, located approximately 390 nm south of Yokosuka, Japan, has tracked eastward at 09 knots over the past six hours. Maximum significant wave height is 6 feet.

Animated multispectral imagery shows the low level circulation has remained fully exposed and totally void of any deep convection.

The system is stripped of vertical structure and is now in a weak steering pattern north of the subtropical ridge in cool waters (below 26 celsius). It is expected to dissipate as a significant tropical cyclone over water in the next 12 hours.

Typhoon Chaba/Katring (16W), located approximately 225 nautical miles south-southwest of Yokosuka, Japan, has tracked northeastward at 19 knots during the past six hours. Maximum significant wave height is 20 feet.

Early on October 20, the Japan Meteorological Agency (JMA) upgraded an area of low pressure into a tropical depression. Later that day, the JMA reported that the tropical depression slightly intensified.

The next day, the Joint Typhoon Warning Center started monitoring the system as tropical depression 16W. On October 23, the system entered the Philippine Area of responsibility and the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) started monitoring the system as Tropical Depression “Katring”.

On October 24, the JMA and JTWC upgraded the tropical depression into a tropical storm and the JMA named it “Chaba”. On October 25, the JMA further upgraded the storm into a Severe Tropical Storm. Later that day, the JTWC upgraded the storm into a Category 1 Typhoon.

Early on October 26, the JMA further upgraded the storm into a Typhoon.[102] Early on October 27, the JTWC upgraded the typhoon into a Category 2 Typhoon. The following day the JTWC upgraded the system into a Category 4 Typhoon, but soon after weakened back to a Category 3. By late on October 29, the JMA had downgraded the typhoon into a Severe Tropical Storm while the JTWC downgraded it into a Category 1 Typhoon.

Tokyo Bay, previously called Edo Bay, is located in the southern Kantō region of Japan. It is surrounded by the Boso Peninsula (Chiba Prefecture) to the east and the Miura Peninsula (Kanagawa Prefecture) to the west.

The ports of Tokyo, Chiba, Kawasaki, Yokohama, and Yokosuka are all located on Tokyo Bay.

On the western coast of Tokyo Bay, between Tokyo and Yokohama, the Keihin Industrial Area has been developed since the Meiji Era.

This was expanded to the Keiyo Industrial Area along the north and east coasts after World War II. The latter appears bright white here.

The only natural island in the Bay is Monkey Island. There are however many artificial islands built as naval fortifications during the Meiji and Taishō period. In the image, many ships can be seen moving around the bay and navigating up and down the rivers connected to it.
