TYPHOON XANGSANE HITS THE CENTRAL PHILIPPINES

Typhoon Xangsane (known as Milenyo in the Philippines) is bringing strong winds and heavy rains to the central Philippines after making landfall on the central Philippines island of Samar east of the province's capital of Catarman. The storm was reported to have winds gusting to 150 kph (93 mph) as it made landfall. The Tropical Rainfall Measuring Mission (TRMM) satellite has proven itself to be a valuable tool for monitoring tropical cyclones. TRMM captured these images of Xangsane as it developed near the Philippines.

 Link to image of  ts  XANGSANE 25 sep,  2006 top down  view Xangsane began as a tropical depression on the 25th of September 2006 in the western Philippine Sea just 200 miles east of the central islands. The first image from TRMM shows the depression as it was nearing the central Philippines. The image was taken at 7:39 UTC 25 September 2006 and shows the horizontal distribution of rain intensity as seen from the TRMM satellite. Rain rates in the center swath are from the TRMM Precipitation Radar (PR), a first-of-its-kind space-borne precipitation radar, while rain rates in the outer swath are from the TRMM Microwave Imager (TMI). The rain rates are overlaid on infrared (IR) data from the TRMM Visible Infrared Scanner (VIRS). TRMM shows that the depression consists of a coherent area of light (blue) to moderate (green) rain. A few isolated areas of heavy rain (shown in red) are also present. At this time, there is little evidence of organization. The system has no eye or eyewall and no evidence of banding (curvature) in the rain field, which would indicate the presence of a circulation. The system did, however, become better organized and was named Tropical Storm Xangsane about 10 hours after this image was taken.

 Link to image of 	     2006 As Xangsane headed west-northwest towards the central Philippines, initial intensification was slow with the system remaining a tropical storm on the 26th (local time). However, as it was nearing Samar, Xangsane began to intensify more rapidly. The next image was taken by TRMM at 21:36 UTC 26 September as Xangsane was bearing down on northern Samar in the central Philippines. TRMM now reveals a very different looking system. Xangsane now has a complete eyewall composed of moderate to heavy rain (green ring with areas of red), surrounded by spiral rainbands. These features are consistent with the well-developed circulation of a mature tropical cyclone.

The higher tops are indicated in red. Deep convective towers that are part of the eyewall form a ring around the center. These can be a precursor to future strengthening. Additional tall towers are associated with the outer rainbands farther away from the center. At the time of these images, Xangsane was estimated to have sustained winds of 65 knots (75 mph), making it a minimal Category 1 typhoon. However, the storm was in the process of intensifying and became a Category 2 storm just hours later with sustained winds estimated at 90 knots (104 mph) as it neared Samar.

(update september 28) TYPHOON XANGSANE ROARS THROUGH THE PHILIPPINES

Typhoon Xangsane (known as Milenyo in the Philippines) is shown heading into the South China Sea after a devastating blow to the Philippines. At least 61 deaths were attributed to the storm. Xangsane temporarily weakened over the Philippines but regained strength over the South China Sea. The image above was made from data captured by the TRMM satellite on 28 September at 0628 UTC.

(update October 1 ) TYPHOON XANGSANE HITS CENTRAL VIETNAM

Typhoon Xangsane hit central Vietnam on 1 October causing flooding and widespread damage. This image was made using TRMM satellite data captured on 30 September at 0613 UTC when sustained wind speeds were estimated at 115kts (133 mph).
