2006 TROPICAL CYCLONE SEASON FOR THE PHILIPPINES
The Philippines have experienced another busy but typical year in terms of
tropical cyclone activity. The island chain often finds itself directly in
the path of tropical cyclones that have formed upstream in the Western Pacific.
Between 1984 and 2004, approximately 20 tropical cyclones per year on average
have formed or entered the region with nearly 9 of those making landfall in the
Philippines. In an average year, the Northwest Pacific basin typically sees 27
named storms, 17 typhoons, and 8.5 typhoons of category 3 or higher. So far
this season there have been 22 storms, 15 typhoons and 7 super typhoons with
nearly 2400 reported fatalities as a result.
For the Philippines, the season began with Super Typhoon Chanchu (locally known
as Caloy), which made landfall as a Category 1 storm on May 11th before passing
through the central Philippines where it left behind 32 dead. Next came Prapiroon
(known as Henry), which cut across Luzon as a mere tropical depression beginning
on July 31st but still killed 6. Xangsane (known as Milenyo) passed through the
central Philippines in late September. This strong storm made its initial landfall
at Category 2 intensity on the 27th and was responsible for at least 200 fatalities
in the islands. Super Typhoon Cimaron (known as Paeng) struck Luzon on October
29th as a powerful category 5 storm and left behind at least 19 persons dead.
This was followed less than two weeks later by Chebi (known as Queenie), which
also hit Luzon. The storm made landfall at Category 3 with only 1 fatality. The
biggest disaster for the season came at the end of November when Super Typhoon
Durian (known locally as Reming) struck Albay province in the central Philippines
on the 30th. The storm dumped a tremendous amount of rain, which combined with
loose volcanic ash on the slopes of Mount Mayon to generate massive mudslides.
At least 1200 people are feared dead. Utor, the final storm of the season and
known locally as Seniang, hit the central Philippines soon after on December 9th
as a Category 1 typhoon. So far, 16 fatalities have been reported in the
Philippines as a result of Utor.
The Tropical Rainfall Measuring Mission or TRMM satellite was launched into service
in November of 1997. It was designed to measure rainfall over the global Tropics
using both passive and active sensors, including the first and only space-borne
precipitation radar. The TRMM-based, near-real time Multi-satellite Precipitation
Analysis (MPA) at NASA Goddard Space Flight Center monitors rainfall over the global
Tropics. MPA rainfall totals resulting from tropical cyclones for the 2006 season
are shown here for the Philippines and surrounding region. It can be seen that
upwards of 30 inches of rain fell across large portions of the northern and central
Philippines as a result of passing tropical cyclones (red areas). The southern
islands, in contrast, saw far less due to the absence of any passing storms in the
immediate vicinity.
