The Tropical Rainfall Measuring Mission or TRMM satellite came into service in November of 1997 with the primary mission of measuring rainfall in the Tropics using a combination of passive microwave and active radar sensors. The TRMM- based, near-real time Multi-satellite Precipitation Analysis (MPA) at the NASA Goddard Space Flight Center monitors rainfall over the global Tropics. MPA rainfall totals are shown here for the period 19 to 29 November 2007 for the Philippines and the surrounding region. Two separate areas of heavy rain lie just off the coast of Vietnam over the western South China Sea and right along the eastern edge of the Philippines in the western part of the Philippine Sea. These two areas are associated with Hagibis and Mitag, respectively. The storm tracks are shown by the thin black lines with 00 UTC positions overlaid with storm symbols. With Hagibis, the highest rainfall totals of over 500 mm (~20 inches, shown in the darkest red) occur where the storm made it's "U-turn". With Mitag, similar peak totals occur to the left of and right along its path as it approached the central Philippines. Some of this heavy rain is seen to impact the far eastern islands. The northern island of Luzon, where Mitag made landfall, received on the order of 100 to 200 mm (~4 to 8 inches) of rain (shown in green).

In addition to the Philippines proper, the storms, especially Hagibis, had a impact on fishing vessels in the region. So far, 26 fishermen are still missing from a Filipino fishing vessel that capsized in the South China Sea during the storm along with two rescue pilots. Two Chinese fishing vessels also sank in the area with 9 crew still missing.
