The Global Precipitation Measurement mission, also called the GPM, has a core satellite that provides images of storm formations from space. The images that they release allow people to have a clear overview of what they could expect from the weather condition as reported on the news. More importantly, it serves as a warning for those who reside in areas where heavy rainfall could bring about flooding and other disastrous situation, so that they could prepare for the worse. 

The satellite passed by the Eastern Pacific Ocean and that's where it became a witness to the brewing strength of the Tropical Storm Mario. Apart from the images, it also provided a measurement of the rainfall that people can expect and the numbers are not looking as good. 

At 3:46 a.m. of September 18, 2019 EDT, GPM was able to detect the heaviest rainfall measurement at the southeastern side of the storm formation. It has a rate of over 36mm every hour. In the other quadrants of the storm, lighter rainfall rating was given. The band of thunderstorms that comes with towards the center also have relatively lighter rain. The forecasters working at the National Hurricane Center (NHC) of project NOAA has already incorporated the data collected to the ones they already have to make a more accurate weather forecast. 

It all started as a Tropical Depression and developed. It reached the Tropical Storm level only on September 17 after only six hours. At the forecast released by the NHC, the center of this tropical storm Mario was located 14.5 degrees north at the longitude 111.0 degrees west. Mario is travelling fast, but is still far from hitting the islands, that's why there are no released of coastal warming or watchout news to residents of a particular area.

Mario is moving towards the northwest at 12mph at a constant speed. However, on Thursday, the tropical storm Mario is expected to reduce its speed. It is further expected to become stationary early on Friday and throughout the rest of the weekend. 

The maximum sustained winds of this tropical storm is at the rate of 65 mph, with an estimated central pressure at 996 millibars. Hurricanes are considered as one of the most powerful forces of nature. NASA and their expertise in space exploration and scientific processes continue to provide essential information through forecasts and images to ensure that the citizens all over the world are given the latest information.
