Tropical Depression 9, an Impending Tropical Storm

According to an article on Nasa.gov a Tropical Depression, a precursor to a Tropical Storm, a storm less severe than a hurricane, by the name of Tropical Depression 9 is expected to “intensify over the next day or so.” The author, Hal Pierce claims that the reason the depression is expected to intensify is due to the vertical wind shear, the amount that the winds change with height, being low, and the fact that the depression is currently moving over warm waters.

            The GPM, Global Precipitation Measurement, an organization attempting to measure global rain fall amounts, found a series of storms within the Gulf of Mexico which were puring down upwards of 4.1 mm of rain per hour. According to Jeff Haby on theweatherprediction.com anything above .31 inches of rain per hour is considered to be a “heavy rain.” These series of storms happen to be falling at a rate several times higher than what could be considered a heavy rain fall. A few of these storms have begun to reach heights exceeding 9.9 miles. If the tropical storm continues to grow in this manner it will become a tropical storm by the name of Hermine.
