The Northern Philippines Island of Luzon suffered yet another direct hit from a
super typhoon this season when Super Typhoon Durian (known as "Reming" in the
Philippines) made landfall on the southeastern part of the island. The storm
came ashore on the 30th of November 2006 with sustained winds reported at 190 kph
(118 mph) by the Philippine weather service with gusts to 225 kph (140 mph).
Luzon has been hit hard this year. Super Typhoon Xangsane also hit the southern
part of the island back on the afternoon (local time) of September 27th. Super
Typhoon Cimaron struck northern Luzon on the evening of October 29th, and more
recently Typhoon Chebi again hit northern Luzon on November 11th.
The 24th tropical depression of the West Pacific season formed early on the
morning of November 26th (local time) south of Guam and became a minimal tropical
storm, named Durian, later that same day. The Tropical Rainfall Measuring Mission
(TRMM) satellite was placed into its low-earth orbit in November of 1997. Its
primary mission is to measure rainfall from space; however, it has also served as
a valuable platform for monitoring tropical cyclones, especially over remote parts
of the open ocean. TRMM captured these images of Durian as it was making its way
across the West Pacific. This first image was taken at 23:24 UTC on 25 November
2006 just before TD #24 became a named tropical storm. The image shows the
horizontal distribution of rain intensity looking down on the storm. Rain rates in
the center of the swath are from the TRMM Precipitation Radar (PR), while those in
the outer portion are from the TRMM Microwave Imager (TMI). The rain rates are
overlaid on infrared (IR) data from the TRMM Visible Infrared Scanner (VIRS). TRMM
reveals that the soon-to-be-named Durian consists of a broad area of light to
moderate rain (blue and green areas, respectively). There is no evidence of an eye
nor of any banding, indicating that the storm is still in its early formative stages.

Over the next couple of days, Durian continued to track off to the west-northwest
taking it into the south-central Philippine Sea. During this period, Durian was
slow to intensify and was still a tropical storm on the night of the 27th. Durian
finally became a minimal typhoon on the afternoon of the 28th as the storm was
beginning to take aim at the central Philippines. On the 29th, Durian intensified
significantly and became a super typhoon with maximum sustained winds estimated at
135 knots (155 mph) by the Joint Typhoon Warning Center. The next image from TRMM
was taken at 22:50 UTC 29 November (6:50 am local time) as Durian was bearing down
on Catanduanes Island in the central Philippines. Although the center of the storm
does fall within the PR swath in this image, it is clear from the TMI that Durian
has a well-defined eye surrounded by a symmetric eyewall (green ring). The extreme
cyclonic winds in intense storms tend to smear out eyewall features. At the time
of this image, Durian was a strong Category 4 typhoon with maximum sustained winds
estimated to be 130 knots (150 mph) by the Joint Typhoon Warning Center.
Soon after this image was taken Durian's northern eyewall passed over Virac on the
southern tip of Catanduanes Island. The center then made landfall along the south-
eastern portion of Luzon in the province of Albay before continuing on westward
through the central Philippines.
