Track TD 06W - July 13th, 2009

Tropical Depression Huaning (06W), located approximately 135 nautical miles south of Taipei, Taiwan, has tracked west-northwestward at 13 knots over the past 6 hours.

Animated multispectral and radar based imagery
indicates that TD 06W has made landfall in Taiwan and is tracking across southern Taiwan.

Increased convection has developed over the past 6 hours, mostly from terrain-enduced lifting as the system moves over the mountainous costal region of Taiwan.

Its northern and western rain bands are now spreading across Taiwan, while its southern rain bands are affecting extreme northern Luzon, particularly the Batanes Group of islands.

Moderate to heavy rains with winds, squalls and thunderstorms can be expected, with 1-day rainfall accumulations of 150 up to 250 mm along the storm’s rain bands.

Residents in low-lying areas and steep slopes must remain alert and seek evacuation for possible life-threatening flash floods, mudslides and landslides due to the anticipated heavy rains brought about by this system.

Current track speed will take the system into the Taiwan Strait within the next 12 hours, briefly causing an increase in intensity. This will be short-lived as the system moves into mainland China, quickly dissipating as it tracks over land.

Surface to mid-level ridging to the northeast of TD 06W is the primary steering influence and will cause the system to track more northward beyond TAU 12. Maximum significant wave height is 9 feet.
