Another typhoon in the northern Philippines really is something to be scared about, and Mirinae is expected to make landfall there in the mid-morning hours on Halloween, October 31. Mirinae will be the fourth major storm to hit the Philippines in one month bringing more rain to an already flood-weary region.
NASA's Tropical Rainfall Measuring Mission (TRMM) satellite is already hard at work analyzing rainfall, to provide meteorologists with an idea of what can be expected when the storm hits.

NASA and the Japanese Space Agency's TRMM satellite flew over Typhoon Mirinae on October 29 at 1018 UTC and measured its rainfall from space. Mirinae had moderate rainfall between .78 to 1.57 inches per hour around its center. TRMM images are made at NASA's Goddard Space Flight Center in Greenbelt, Md. and take some ingenuity to create. A typical TRMM rainfall image combines the infrared and visible channels overlaid with a precipitation analysis from the TRMM Microwave Imager and PR instrumen
